China Trash Ban Creates Crisis for Recyclers

Just less than $6 billion worth of U.S. waste was sent to China last year to be converted into packaging and products, and then shipped back to the United States and other markets. Scrap recyclers had taken advantage of low shipping costs for empty containers returning to China after the ships had unloaded their goods on the U.S. West Coast.

Today, that flow of trash is just a trickle, the result of a Chinese ban that went into effect Jan. 1 on many types of foreign garbage, from mixed papers to waste textiles.

The result of the ban is seen at a recycling facility in Anaheim, California, owned by Republic Services, a national company headquartered in Phoenix, Arizona. The parking lot of the materials recovery facility (MRF) is brimming with 2,400 bales of mixed paper that once would have been bound for China.

The surplus is a result of an unprecedented 12-day backlog, said James Castro, the facility’s general manager.

And it’s not clear where it’s all going.

China has banned imports of mixed paper, as well as low-grade plastics, certain metals and other types of waste. In April, it expanded the ban, to go into effect later this year, to include more metals and chemical waste. A ban on additional kinds of scrap, including waste timber, is being targeted for the end of 2019.

Less-contaminated scrap

It has also imposed stricter contamination standards on the scrap it does accept, allowing only 0.5 percent contaminants, down for most materials from 1.5 percent.

That has slowed the sorting process, said Richard Coupland, Republic’s vice president of municipal sales.

Further complicating matters, the ban has led to a huge reduction in worldwide prices on recyclable goods, such as mixed paper.

One year ago, bales of unsorted paper, like those now stacked in the parking lot, would have been worth $100 a ton. Today, each ton is worth “less than $5, or negative in some markets,” including shipping costs, Coupland said. He added that much of the industry’s backlog may end up in landfills.

To the north in the city of Azusa, Waste Management’s MRF is also dealing with tightened standards for the workers and sorting machines that use magnets, optical sensors and other means to separate the waste. Executives say they are tweaking a costly system that was designed to meet China’s insatiable craving for scrap.

Asia-based journalist Adam Minter, author of the book Junkyard Planet: Travels in the Billion-Dollar Trash Trade, sums up the dilemma facing these companies.

“Recycling is about manufacturing,” Minter said, “and if somebody doesn’t want to use those raw materials, then putting stuff in your recycling bin is doing nothing more than playing with your garbage.”

He says China’s trash ban is spurred partly by a desire to clean up the environment, but even more by nationalism and a desire for political control.

“When you see China pushing against the recycling industry,” Minter said, “it’s really pushing against private industry and in favor of state-owned enterprises, and that is very much in line with the way that Chinese economic policy has been going for the last five years.”

​‘Shockwaves around the world’

Some environmentalists have welcomed the trash ban.

Greenpeace East Asia plastic campaigner Liu Hua said it will send “shockwaves around the world” and force countries to confront their attitudes toward waste, especially environmental contaminants like plastics.

China expert Joshua Goldstein of the University of Southern California said the ban will have social repercussions in China.

Goldstein has studied the informal sector of 3-5 million small-scale recyclers, entrepreneurs whom he says are “picking through (trash) and making their lives slightly better every day through the money that they made.”

“It had environmental repercussions,” he said, “but it also raised 3 to 5 million households out of poverty.”

Goldstein said China faces hurdles to create an operation as efficient.

Companies are also searching for new markets. More recyclable scrap from the United States will now go to India, Vietnam, Malaysia, Thailand or Indonesia, but industry experts say shipping costs are high and demand in those countries is limited.

As commodity prices drop, there is hope for increased use for scrap such as mixed paper in the United States.

​Cleaning up waste

Brent Bell, vice president of recycling operations for Waste Management, said his company is also cleaning up its waste to meet the higher standards that China and other countries are demanding.

“I think as an industry, we’re all at fault to some degree,” Bell said, noting the company is working to educate consumers about better recycling. “Something we all missed as an industry,” he added. “Whether we’re shipping material to China, to India, or even to Louisiana, our customers all want to make sure the material is as clean as possible.”

Republic’s Coupland said the waste and recycling industry needs to work with local communities to find a new business model to replace one that has become unsustainable. It could mean, he said, an increase in the rate that consumers pay for hauling away their trash.

China may yet make adjustments to its policies, USC’s Goldstein added.

Paper fiber is hard to replace, he notes, and China may loosen its bans to bring in the raw materials that its manufacturers require.

“What parts of this reform, this ban, are going to be long term and what parts are going to be short term is still quite unclear,” Goldstein said. But he noted that the economics of the recycling industry are changing.

Seaweed May Hold Key Ingredient for Ocean Friendly Sunscreen

As summer draws near in the Northern Hemisphere, millions of people will slather on sunscreen to protect themselves from the sun’s harmful rays. But most sunscreens contain chemicals harmful to the oceans. Now researchers in London have developed a compound found in seaweed that could be the basis for a new generation of environmentally friendly sunscreens. As VOA’s Julie Taboh reports, they may not only protect us from damaging rays from the sun but also act as an anti-oxidant.

North Korea Uses US Tech for ‘Destructive Cyber Operations’

North Korea’s senior leadership has been exploiting loopholes in international sanctions to obtain the U.S. technology that Pyongyang uses to conduct “destructive cyber operations,” according to a global cyberthreat intelligence company.

Recorded Future, based in Massachusetts, found that while export bans and restrictions are somewhat effective in keeping North Korea from acquiring technology for its nuclear weapons program, sanctions fail when it comes to regulating computer products from entering into North Korea.

“Because of the globalized nature of technology production and distribution, the traditional export control is not really working for [computer] technology,” said Priscilla Moriuchi, one of the authors of “North Korea Relies on U.S. Technology for Internet Operations.” “It may work quite well for ballistic missile parts or fissile material, but the system is not designed to limit technology transfer, and it’s not optimized for that.”

​Upcoming summit

In the report, Moriuchi and her co-author, Fred Wolens, call for a “globally robust unified effort to impose comprehensive sanctions” on North Korea, warning that without this Pyongyang “will be able to continue its cyberwarfare operations unabated with the aid of Western technology.”

The report was released days before North Korean leader Kim Jung Un and U.S. President Donald Trump are scheduled to meet in Singapore for a summit focused on ending the North’s nuclear weapons program in exchange for economic incentives and security guarantees.

But some consider North Korea’s cyberthreat capabilities as damaging as the threat of its nuclear weapons, Morgan Wright, a former a senior adviser in the U.S. State Department Antiterrorism Assistance Program, wrote in The Hill.

Even as advance teams prepared for the June 12 summit, North Korean cyberattacks continued, Moriuchi told Cyberscoop. On May 28, it reported the Department of Homeland Security and the FBI released a joint alert about Hidden Cobra, which is associated with North Korea’s hacking activities.

FireEye, a Silicon Valley cybersecurity company, detected cyberattacks by Lazarus, the North Korean hacking effort responsible for stealing millions of dollars from the Bangladesh Central Bank in 2016. Lazarus is also believed responsible for the 2014 Sony Picture’s hack and last year’s WannaCry ransomware attack.

​Defining ‘luxury goods’

How did U.S. technology reach North Korea? Part of the answer lies in “international inconsistencies in the definition of the term ‘luxury goods,’” according to the Recorded Future report. The U.S. “effort to restrict technology exports at the national and international level” has not reaped results because of “varied definitions by nations and [their] inconsistent implementations,” said Moriuchi, a former East Asia analyst for the National Security Agency.

While the United Nations did not include electronics in Resolution 2321, which covered exports to North Korea, when it was issued in 2016, each member nation was allowed to interpret luxury goods. The U.S. has defined luxury goods to include laptop computers, digital music players, large flat-screen televisions and electronic entertainment software. China, in particular, does not “honor the luxury goods listed by other countries when it exports to” North Korea, according to the report.

US exports OK

Another factor is that for seven years in the period spanning 2002 to 2017, “the United States allowed the exportation of ‘computer and electronic products’ to North Korea,” according to the report. The total for those seven years was more than $430,000 of legal exports, and according to Recorded Future, “at its peak in 2014, the U.S. exported $215,862 worth of computers and electronic products to North Korea.”

The Recorded Future report, citing the U.S. Department of Commerce (DOC), said that category includes “computers, computer peripherals (including items like printers, monitors and storage devices), communications equipment (such as wired and wireless telephones), and similar components for these products.”

Much of that equipment remains in use, according to Recorded Future, and North Korea’s ruling elites, including party, military, and intelligence leaders and their families, have long been known to use products manufactured by U.S. companies such as Apple, Microsoft and IBM to access the internet.

A third element in how the U.S. tech went astray is what the report called North Korea’s “sophisticated sanctions evasion operation, which uses intermediaries and spoofs identities online.”

As an example, the study points to North Korea’s shell company Glocom with which Pyongyang “used a network of Asian-based front companies to buy computer components from electronic resellers, and the payment was even cleared through a U.S. bank account.” The United Nations found that Glocom was tied to Pan Systems Pyongyang, whose director, Ryang Su Nyo, reports to Liaison Office 519 in the North Korean intelligence agency’s Reconnaissance General Bureau.

​Just like us

North Korea’s elites surfed and browsed just like users outside North Korea until recently when the Recorded Future researchers found “a stark change” in the elite’s usage patterns as they “migrated almost completely” from Facebook, Google and Instagram “to their Chinese equivalents — Alibaba, Tencent and Baidu,” and over the course of a few months “dramatically increased” their use of internet obfuscation services, such as virtual private networks (VPN), virtual private servers (VPS), transport layer security (TLS) and the Onion Router (Tor).

While tracking the change in activity from December 2017 to April 2018, researchers found “the overwhelming presence of American hardware and software on North Korea networks and in daily use by senior North Korean leaders.”

While U.S. exporters are responsible for understanding and adhering to export regulations, the study indicates even the implementation of robust compliance procedures were insufficient in preventing banned U.S. computer products from reaching North Korea.

U.S. export enforcement rests with the Office of Foreign Asset Control, the Office of Export Enforcement and Homeland Security Investigations. The U.S. is one of the only countries that enforces its export laws outside of its national boundaries, placing federal agents in foreign countries to work with local authorities.

Widespread international sanctions were imposed beginning in 2006, when North Korea conducted its first nuclear weapons test. In response, the U.N. passed two resolutions (Resolution 1695 and 1718) banning a broad range of exports to North Korea by any U.N. member states. The U.N. subsequently expanded those sanctions through a number of resolutions that prohibit and restrict exporting items ranging from missile material to oil to North Korea.

The case of ZTE

The Recorded Future report mentions Chinese manufacturer ZTE (Zhongxing Telecommunications Equipment) as a case where the implementation of export regulation failed, pointing out that the U.S. had the chance to enforce its export laws when the company was under Export Administration Regulation (EAR), a dense set of laws regulating exports.

ZTE was initially placed on the so-called Entities List for violating U.S. sanctions for selling products containing U.S. goods to Iran and North Korea in March 2016. For two years, the company and the U.S. government attempted to reach an agreement over penalties and how to verify that ZTE had stopped violating U.S. sanctions.

The Department of Commerce (DOC) ended the negotiations and imposed a denial order that banned U.S. companies from selling to ZTE for seven years.

In May, the DOC lifted the denial order, which would have put ZTE out of business, and allowed ZTE to purchase components from U.S. companies. The move came after threats of a trade war and Trump’s intervention.

Moriuchi said if the U.S. had let ZTE fail, it would have sent “a huge message to the rest of the world that there is no [company] too big to fail” and that “the U.S. government takes export control very seriously.”

In the end, “an opposite message ended up being sent with the administration’s deal with China, and that there are companies too big to fail especially if that company … has significant interest with the United States,” she said, adding the case demonstrated that “you can circumvent U.S. export control as a company and in the end, survive.”

The U.S. enforces its export laws through the DOC and regulates them through EAR, which not only restricts commercial goods and technologies from reaching hostile countries but also regulates the re-export of U.S. goods and technologies from one foreign country to another.

Until 2008, U.S. sanctions prohibiting exports to North Korea were implemented through the Trading with the Enemy Act, through which the U.S. government banned any exports to designated countries including North Korea.

Subsequently, the Obama administration issued the North Korea Sanctions Regulations and a number of Executive Orders (13551, 13570, 13687, and 13722) to further prohibit various measures, including exports of “goods, services or technology to North Korea.”

Additionally, numerous U.S. sanctions were imposed against North Korea under Trump’s “maximum pressure” campaign, especially in 2017 during Pyongyang’s nuclear weapons and ballistic missiles tests, which also saw the U.N. issue new sanctions.

Fog Catchers Conjure Water Out of Moroccan Mist

Growing up on Mount Boutmezguida in southwest Morocco on the edge of the Sahara desert, Khadija Ghouate never imagined that the fog enveloping the nearby peaks would change her life.

For hours every day and often before sunrise, Ghouate and other women from nearby villages would walk 5 km (3 miles) to fetch water from open wells, with girls pulled out of school to help and at risk of violence on the lonely treks.

But with groundwater levels dropping due to overuse, drought and climate change, the challenge to get enough water daily was becoming harder, and almost half of people in the local area sold up and quit rural life after generations for the city.

As the future of the traditional Berber region by Mount Boutmezguida floundered, a mathematician whose family came from the area had a eureka moment gleaned from living overseas – using fog to make water.

Now Ghouate’s village is connected to the world’s largest functioning fog collection project, alleviating the need to collect water that fell mainly on women, and with state-of-the-art equipment setting an example for other projects globally.

“You always had to go to the wells, always be there, mornings, evenings,” said Ghouate, a mother-of-three, as she prepared lunch for her family, showing off the tap in her home.

“But now water has arrived in our house. I like fog a lot.

The project, running since 2015 after nine years of surveys and tests, was founded by the Moroccan non-government organization Dar Si Hmad, which works to promote and preserve local culture, history, and heritage.

It was the brainchild of mathematician and businessman Aissa Derhem whose parents were originally from Mount Boutmezguida where the slopes are covered in mist on average 130 days a year.

Derhem first came across fog collection when he learned of one of the world’s first projects – in Chile’s Atacama Desert – while he living in Canada in the 1980s studying for his PhD.

But it was not until visiting his parents’ village years later that he realized the mountainous location, situated at the edge of the Sahara and about 35 km (22 miles) from the Atlantic Ocean, was perfect for fog.

Ideal Location

Mist accumulates in coastal areas where a cold sea current, an anticyclone and a land obstacle, such as a mountain range, combine.

“When the sea water evaporates, the anticyclone … stops it from becoming rain, and when it hits the mountain, that’s where it can be gathered,” Derhem told the Thomson Reuters Foundation, looking out from the top of Mount Boutmezguida besides a small building used as a fog observatory and tool deposit.

“If we look at the planet, we see this happening in all tropical regions … In Chile and Peru in Latin America. The Kalahari desert in Africa. In Western Australia. Around the Thar desert in India and in California,” he listed as examples.

Developed in South America in the 1980s, fog collection projects have since spread globally to countries including Guatemala, Ghana, Eritrea, Nepal and the United States.

In Morocco, Dar Si Hmad has built a system of nets stretching about 870 square metres – about 4.5 tennis courts.

These nets are hung between two poles and when wind pushes the fog through the mesh, water droplets are trapped, condense and fall into a container at the bottom of the unit with pipes connecting the water to reservoirs.

Derhem hopes the success of the Mount Boutmezguida scheme can help other areas in West Africa and in North Africa – where the United Nation’s Food and Agriculture Organization (FAO) says fresh water resources are among the world’s lowest.

Studies show climate change impacting water patterns globally and Derhem said in Morocco levels have dropped to about 500 cubic meters a person a year from about 1,500 cubic meters a person in the 1960s on calculations based on government figures.

Challenges Too

The principles behind fog collection are simple, and throughout nature examples exist of creatures capturing moisture from the air in the most arid conditions, ranging from beetles in the Namib Desert to lizards in the Australian outback.

But creating a water collection project on a large scale comes with challenges, as the research and development, as well as the infrastructure and technology involved in expanding and developing fog collection projects, can be costly.

The project at Mount Boutmezguida, however, has been a trailblazer for other projects due to its equipment, according to its founders.

The original nets used were insufficiently resistant to the high winds and tore but a partnership with the German non-profit Water Foundation allowed Dar Si Hmad to develop a stronger net.

The CloudFisher was described by the WaterFoundation as the first maintance-free fog collector that can withstand wind speeds of up 120 kph with flexible troughs following the movement of the net in the wind.

Now collected water is filtered and combined with underground water before being distributed to villages on the grid with homes paying for water through a pre-paid system.

The initial pilot project served five villages. At present, the 870 square metres of nets installed reach about 140 families – 14 villages – while a second set of nets is being built.

“Fog is like aeroplanes at the start. At the beginning they were only little toys but, with some effort, things have changed … but it needs investment,” said Derhem.

“Along the coast, there is three times as much fog as there is available on Mount Boutmezguida. The government spends millions for water desalination processes. This is something that is worth exploring.”

For with dry wells comes anxiety and risk but also the unraveling of traditional livelihoods and communities.

Mohamed Zabour, president of the local municipality, said more than 60 percent of the inhabitants of the region live without running water in their homes.

Between 2004 and 2014, 2,000 of the 5,000 local residents moved to cities.

“Our region is rich but it needs infrastructure. And water is one of the priorities,” said Zabour.

“If we don’t find a solution in the next 10 years, it’s going to be a catastrophe … It’s going to be like a desert. Empty.”

For Ghouate, the fog scheme has improved village life.

“When we were kids, we didn’t even know what it meant to need water  … Now there is less rain and if I still had to go to the wells, I wouldn’t find much water now,” she said. “Everything is about water, everything. I don’t have to worry about it anymore.”

Ukraine Approves Anti-Corruption Court, Fires Finance Minister

Ukraine’s parliament has voted to establish an anti-corruption court in an effort to meet the criteria to receive $17.5 billion from the International Monetary Fund.

 

Before the IMF releases the funds needed to shore up Ukraine’s struggling economy, it will have make sure the court’s laws are IMF compliant. The West has repeatedly called on Ukraine to reform it political system and establish an independent body to fight corruption.

 

“What we’ll be looking to see is that it ensures the establishment of an independent and trustworthy anti-corruption court that meets the expectation of the Ukrainian people,” IMF spokesman Gerry Rice said at a briefing Thursday.

 

President Petrol Poroshenko said the court was in line with Western recommendations and Ukrainian law.  

 

Last year Poroshenko rejected the need for an anti-corruption court, saying such institutions are needed in “Kenya, Uganda, Malaysia and Croatia” but not in Western Europe or the United States.

 

While the approval of the court was seen as a positive, Ukraine also likely dismayed the West by firing Finance Minister Oleksandr Danylyuk, a respected reform advocate.

Danylyuk’s ouster came after he took on Prime Minister Volodymyr Groysman, accusing him of stalling reforms of the state tax service that are needed to combat corruption.

 

Before the parliament voted on his ouster, Danylyuk addressed the lawmakers, telling them he had been accused of “defending the interests of international organizations.”

 

But, “I am defending the interests of Ukrainians,” he said.

Construction Planned to Prepare Alaska’s Arctic Refuge for Oil Drilling

The Trump administration said Thursday it would spend $4 million on construction projects in the Arctic National Wildlife Refuge in preparation for oil drilling in the nation’s biggest wildlife park.

In an announcement that touted planned improvements to U.S. Fish and Wildlife Service visitor facilities, the Department of the Interior said it has approved spending on projects for “Oil Exploration Readiness” in the coastal plain of the Arctic refuge.

The Trump administration is pushing for an oil lease sale in the refuge as early as next year. The tax-overhaul bill passed by the U.S. Congress last December includes a provision mandating two oil lease sales, each offering at least 400,000 acres (161,874.26 hectares), within seven years.

True wilderness refuge

The 19-million-acre (7.7 million-hectare) Arctic refuge, the largest in the U.S. national wildlife refuge system, contains some of the wildest territory in North America. There are no roads, established trails or buildings within the refuge border, and no cell phone service, according to the Fish and Wildlife Service.

“This is a true wilderness refuge,” the Arctic refuge website advises.

Political and business leaders in oil-dependent Alaska have tried for decades to pry open the refuge’s coastal plain, which is believed to hold potential for billions of barrels of oil.

But the plain, between the mountains of the Brooks Range and the Arctic Ocean, is prized for its importance to caribou, polar bears and other wildlife. Oil development there had been banned until Alaska Senator Lisa Murkowski led a move to insert a pro-drilling provision into the 2017 tax bill signed by President Donald Trump.

Some Alaskans opposed

In Alaska, the development plan is largely embraced, but not universally so. Drilling opponents gathered outside of last week’s Anchorage and Fairbanks hearings about the proposed lease sales to protest the plan.

Interior spokeswoman Heather Swift, in an email, said the $4 million “will be used to support six projects designed to improve and construct existing outbuildings, facilities and research operations.”

That work will include improvements to facilities outside the refuge, in the Inupiat village of Kaktovik and at Galbraith Lake along the Trans-Alaska Pipeline corridor, she said in the email.

Large appropriation

The $4 million appropriation for Arctic refuge projects is one of the largest single items in a total of $50 million in planned DOI construction spending.

“The president is a builder, he loves to build and he loves our public lands, so it is a natural fit that the Trump administration is dedicating so much attention to rebuilding our aging Fish and Wildlife Service infrastructure,” Secretary Ryan Zinke said in a statement Thursday.

A partnership of three companies is seeking to do seismic surveys in the refuge starting this winter. That plan, from SAExploration and two Alaska Native corporations, was panned by the U.S. Fish and Wildlife Service, the Washington Post reported last month.

There has been no decision on that application, Swift said Thursday. “It was a draft application. The department does not make decisions based upon early drafts,” she said by email.

Facebook Says Privacy-setting Bug Affected as Many as 14M

Facebook said a software bug led some users to post publicly by default regardless of their previous settings. The bug affected as many as 14 million users over several days in May.

 

The problem, which Facebook said it has fixed, is the latest privacy scandal for the world’s largest social media company.

 

It said the bug automatically suggested that users make new posts public, even if they had previously restricted posts to “friends only” or another private setting. If users did not notice the new default suggestion, they unwittingly sent their post to a broader audience than they had intended.

 

Erin Egan, Facebook’s chief privacy officer, said the bug did not affect past posts. Facebook is notifying users who were affected and posted publicly during the time the bug was active, advising them to review their posts.

 

The news follows recent furor over Facebook’s sharing of user data with device makers, including China’s Huawei. The company is also still recovering from the Cambridge Analytica scandal, in which a Trump-affiliated data-mining firm got access to the personal data of as many as 87 million Facebook users.

 

Jonathan Mayer, a professor of computer science and public affairs at Princeton University, said on Twitter that this latest privacy gaffe “looks like a viable Federal Trade Commission/state attorney general deception case.” That’s because the company had promised that the setting users set in their most recent privacy preferences would be maintained for future posts. In this case, this did not happen for several days.

 

Facebook’s 2011 consent decree with the FTC calls for the company to get “express consent” from users before sharing their information beyond what they established in their privacy settings. Even if the bug was an accident on Facebook’s part, Mayer said in an email that the FTC can bring enforcement action for privacy mistakes.

 

Facebook, which has 2.2 billion users, says the bug was active from May 18 until May 27. While the company says it stopped the error on May 22, it was not able to change all the posts back to their original privacy parameters until later.

 

The mistake happened when the company built a new way for people to share “featured items” on their profiles. These items, which include posts and photo albums, are automatically public. In the process of creating this feature, Facebook said it accidentally made the suggested audience for all new posts public.

 

When people post to Facebook, the service suggests a default distribution for their posts based on past privacy settings. If someone made all posts “friends only” in the past, it will set their next post to “friends only” as well. People can still manually change the privacy level of the posts — anywhere from “public” to “only me” — and this was the case while the bug was active as well.

Scientists Say Cost of Sucking Carbon from Thin Air Could Tumble

High costs of extracting greenhouse gases from thin air could tumble with new technologies that can help to combat climate change, scientists said on Thursday.

Carbon Engineering, a Canadian-based clean energy company, outlined the design of a large industrial plant that it said could capture carbon dioxide from the atmosphere at a cost of between $94 and $232 a ton.

That is well below past estimates of about $600 a ton by the American Physical Society, said David Keith, a Harvard University physics professor and the founder of Carbon Engineering who led the research.

“I hope to show that this as a viable energy industrial technology, not something that is a magic bullet … but something that is completely doable,” he told Reuters of the peer-reviewed study published in the journal Joule.

Carbon Engineering, which has about 40 employees and produces about a ton of carbon dioxide a day from an experimental plant. The technology makes synthetic fuels using only air, water and renewable power.

Keith said an industrial-scale plant could make fuel at a dollar a liter. That would be competitive in California, where low carbon fuel standards to cut pollution from cars and trucks mean high prices.

He said some investors were interested. An industrial plant, costing hundreds of millions of dollars, could capture a million tons of carbon dioxide a year, equivalent to emissions by 250,000 cars.

Other experts welcomed the study as a step to clear up huge uncertainties about the costs of “direct air capture.”

U.N. reports indicate that governments may have to deploy such novel technologies this century to remove carbon from nature and bury it to limit global warming under the 2015 Paris climate agreement.

“Direct air capture is a politically promising route for carbon dioxide removal,” said Oliver Geden, of the German Institute for International and Security Affairs.

And an air capture plant could be built almost anywhere. It would not threaten farmland, unlike options of planting vast forests which soak up carbon dioxide, he said.

Climeworks, a Swiss company and Carbon Engineering’s main rival, also told Reuters it was hoping to cut its production price to $100 a ton in the next 5-10 years, from about $600 now. It sells carbon dioxide to greenhouses as an airborne fertilizer to grow tomatoes or cucumbers.

Jan Wurzbacher, a founder of Climeworks, said more and more governments are likely to jack up penalties on carbon emissions to limit floods, storms and rising seas in coming years, making the technology more viable.

The World Bank says Sweden has the highest carbon taxes, currently 1,150 Swedish crowns ($133) a ton.

Theater Club at NASA Center Gives Scientists Creative Outlet

By day, she’s a cryogenics engineer at NASA’s Goddard Space Flight Center, where she works on what she calls a “baby step toward a mission to Mars.” By night, she participates in Goddard’s Music and Drama Club, often known as MAD. She played keyboard for the club’s spring musical.  

“The work here can get very intense,” said Breon, a 30-year NASA veteran. “We did our thermal vacuum testing a couple of months ago, and it was an around-the-clock, 24/7 operation.” 

The club members include scientists, engineers and managers who work for NASA on projects including weather satellites and space telescopes, and they say the club is a creative outlet for them.  

“We’ve got more engineers per square foot than any other theater group around,” said Randy Barth, who directed the club’s latest musical, “Weird Romance.”

MAD has staged at least one show a year at Goddard since 1970, from “Oklahoma!” and “The Sound of Music” to science-fiction fare. Club members say it helps them with their day jobs and shows the public another side of scientists at the sprawling flight center northeast of Washington.

Astrophysicist Kim Weaver is the club’s president. Doing theater helps her connect with people who aren’t scientists, she says.  

“When I say I’m an astrophysicist, I usually get a blank stare. So in order to get (people) to actually open up and smile at me, I then say I also do theater, because that’s the part that they think is cool,” Weaver said. “You say you’re a scientist, and I think that scares people. They think they can’t talk to you.”

She was a graduate student intern when she saw a flyer about the club’s auditions for “Sweet Charity.” Making the show was what led her to take a job at Goddard. 

“It really helped improve my chances, even in my career,” Weaver said. “I met some more senior astronomers who later on down the line were able to help steer me and guide me in my career path.”

“Weird Romance’” combines science and drama.  

In the first act, “The Girl Who Was Plugged In,” a corporate mogul creates his own celebrity using a beautiful, artificial body that is controlled by a homeless woman. 

The second, “Her Pilgrim Soul,” was adapted from a “Twilight Zone” episode. In it, a projector shows holographic images of a woman that were not programmed into it, to the surprise of the scientists involved. 

One of the production’s stage directions describes a character as having “a smile that could melt frozen methane.” 

Breon considered that a good omen, since her job actually involves melting frozen methane. 

“We have to do more than smile at it, though,” she joked. 

DRC Reports First Confirmed Ebola Case in Over a Week

The Democratic Republic of the Congo has recorded its first confirmed case of Ebola in over a week, the health ministry said Thursday, although medics said they had made significant progress in their efforts to contain the disease.

The patient, a known contact of someone believed to have died from Ebola on May 20, was confirmed positive on Wednesday for the hemorrhagic fever in the rural community of Iboko, the ministry said in a daily report.

Health officials have moved aggressively to contain the epidemic in a bid to head off a repeat of the 2013-16 outbreak in West Africa that killed more than 11,300 people.

Over 1,800 health workers and other people who could have been exposed to the virus have received an experimental vaccine first tested in the waning days of the West Africa epidemic.

Those efforts and the slowing pace of new cases have led health officials to express cautious optimism about containing the outbreak, although its location directly up the Congo River from the capital, Kinshasa, remains a concern.

The last confirmed case before Wednesday was on May 30 in Iboko. The ministry also reported five new suspected cases on Thursday, including two in Mbandaka, a city of 1.5 million people.

In all, the ministry has recorded 38 confirmed, 14 probable and 10 suspected cases, including 27 deaths.

The World Health Organization said Thursday that it was committing $15.6 million over the next nine months to help the nine countries that border Congo to scale up their emergency response capabilities.

Earlier this week, the government of the northern Angolan province of Malanje closed its river border with Congo in response to the outbreak.

Google won’t do artificial intelligence work for weapons, the company said Thursday.  

The company will not work on “technologies that cause or are likely to cause overall harm,” wrote Sundar Pichai, Google’s CEO, in a blog post.

 

Google has come under fire in recent months for its contract with the U.S. Department of Defense to use AI for sifting through drone footage. AI is a field of study whereby a computer or technology is able to do things typically associated with human behavior, such as make decisions, plan and learn.

 

Google and other tech firms have been bringing the advances in AI to fields such as medicine, natural disaster planning, energy, transportation and manufacturing.

But these advances have also led to ethical concerns about the kinds of decisions being made without human input.

“How AI is developed and used will have a significant impact on society for many years to come,” Pichai wrote. “As a leader in AI, we feel a special responsibility to get this right.”

 

Sifting through drone footage

In recent months, more than 4,000 Google employees signed a petition calling for the cancellation of the company’s contract with the Department of Defense as part of the DoD’s Project Maven initiative. They joined other critics in raising alarms that the project could lead to the use of autonomous weapons.

 

Last week, a Google executive reportedly told employees that the company would not seek to renew its Project Maven contract with the military.  

Kirk Hanson, the executive director of the Markkula Center for Applied Ethics at Santa Clara University, which counts Google as a financial supporter, said Google’s contract highlights a larger debate about AI and military applications.

“Until we have trust that those systems will not make mistakes, we’re going to have a lot of doubts about the use of artificial intelligence for autonomous weapons,” Hanson said.

 

Google will continue some work for the military, Pichai said.

 

“We want to be clear that while we are not developing AI for use in weapons, we will continue our work with governments and the military in many other areas,” he said. “These include cybersecurity, training, military recruitment, veterans’ healthcare, and search and rescue.”

Google Bars Uses of its Artificial Intelligence Tech in Weapons

Google will not allow its artificial intelligence software to be used in weapons or unreasonable surveillance efforts under new standards for its business decisions in the nascent field, the Alphabet unit said Thursday.

The restriction could help Google management defuse months of protest by thousands of employees against the company’s work with the U.S. military to identify objects in drone video.

Google instead will seek government contracts in areas such as cybersecurity, military recruitment and search and rescue, Chief Executive Sundar Pichai said in a blog post Thursday.

“We want to be clear that while we are not developing AI for use in weapons, we will continue our work with governments and the military in many other areas,” he said.

Breakthroughs in the cost and performance of advanced computers have carried AI from research labs into industries such as defense and health in the last couple of years. Google and its big technology rivals have become leading sellers of AI tools, which enable computers to review large datasets to make predictions and identify patterns and anomalies faster than humans could.

But the potential of AI systems to pinpoint drone strikes better than military specialists or identify dissidents from mass collection of online communications has sparked concerns among academic ethicists and Google employees.

A Google official, requesting anonymity to discuss the sensitive issue, said the company would not have joined the drone project last year had the principles already been in place. The work comes too close to weaponry, even though the focus is on non-offensive tasks, the official said Thursday.

Google plans to honor its commitment to the project through next March, a person familiar with the matter said last week.

More than 4,600 employees petitioned Google to cancel the deal sooner, with at least 13 employees resigning in recent weeks in an expression of concern.

A nine-employee committee drafted the AI principles, according to an internal email seen by Reuters.

The Google official described the principles as a template that any software developer could put into immediate use. Though Microsoft and others released AI guidelines earlier, the AI community has followed Google’s efforts closely because of the internal pushback against the drone deal.

Google’s principles

Google’s principles say it will not pursue AI applications intended to cause physical injury, that tie into surveillance “violating internationally accepted norms of human rights,” or that present greater “material risk of harm” than countervailing benefits.

“The clear statement that they won’t facilitate violence or totalitarian surveillance is meaningful,” University of Washington technology law professor Ryan Calo tweeted Thursday.

Google also called on employees and customers developing AI “to avoid unjust impacts on people,” particularly around race, gender, sexual orientation, and political or religious belief.

The company recommended that developers avoid launching AI programs likely to cause significant damage if attacked by hackers because existing security mechanisms are unreliable.

Pichai said Google reserved the right to block applications that violated its principles. The Google official acknowledged that enforcement would be difficult because the company cannot track each use of its tools, some of which can be downloaded free of charge and used privately.

Google’s decision to restrict military work has inspired criticism from members of Congress. Representative Pete King, a New York Republican, tweeted Thursday that Google not seeking to extend the drone deal “is a defeat for U.S. national security.”

Foreign Firms Invest in Brazil Oil Despite Fuel Price Strike

Multinational oil companies bought significant stakes in three Brazilian pre-salt oil fields auctioned Thursday, a show of confidence in the future of the energy sector despite a recent strike by truckers over rising fuel prices that brought Latin America’s largest nation to a halt.

The auction, which included several multinationals among the 16 companies bidding, was closely watched to gauge market reaction to the trucking shutdown, which raised questions about the ability of state oil giant Petrobras to set prices without government interference. 

In addition, Petrobras CEO Pedro Parente stepped down last week, saying his presence would be a distraction as the company looked to the future.

Those developments did not appear to present problems for companies that agreed to pay $798 million to explore three of four fields being auctioned. There were no bids on the fourth. 

Shell buys 40 percent

In the first, Shell bought 40 percent while Chevron and Petrobras each bought 30 percent. In the second, BP Energy bought 30 percent, Statoil 25 percent and Petrobras 45 percent. In the third, Statoil and ExxonMobil bought 28 percent each, while Petrobras got 30 percent and Petrogal 14 percent. Petrobras will be the operator in all three.

“This round was extremely successful, getting the attention of large companies,” said Decio Oddone, director of the National Petroleum Agency, which regulates the oil and gas sector in Brazil. “We continue the process of attracting investment for the country.”

Last year, for the first time the government gave private companies the chance to operate pre-salt fields alone.  It was part of President Michel Temer’s plan to increase foreign investment and give Petrobras more independence to set fuel prices.

Government gives in

However, Petrobras’ future is in doubt on the heels of the truckers’ multiday strike that led to widespread shortages in supermarkets and hospitals and the shuttering of thousands of schools. 

The strike ended when the government agreed to subsidize the price of diesel for 60 days and meet several other demands. 

While Temer and Cabinet ministers repeatedly insisted Petrobras would not be messed with, the markets were suspect. During the strike, the company’s stock plunged more than 20 percent on fears that in the future the government would intervene to set prices, a common practice before Temer took power in 2016.

Atlantic reserves

The pre-salt reserves auctioned lie offshore in the Atlantic. They are more than 1 mile (1.6 kilometers) below the ocean’s surface and under a further 2.5 miles (4 kilometers) underneath soil and corrosive salt. 

Eduardo Costa Pinto, an economics professor at the Federal University of Rio de Janeiro, said doubts about Petrobras’ future were likely outweighed by a combination of rising world oil prices and increasingly cheaper costs of pre-salt drilling.

“The overall risk for investors is minimal,” said Pinto.

More Than 14% of US Farm Exports Seen at Risk in Trade Disputes

More than 14 percent of $140 billion in annual U.S. farm exports have been or are likely to be hit by retaliatory tariffs in trade disputes with countries

such as China and Mexico, a top U.S. trade negotiator said Thursday.

Mexico imposed tariffs on American products including steel, pork and bourbon Tuesday, striking back against import duties on steel and aluminum imposed by U.S. President Donald Trump.

The duties raised trade tensions and further complicated efforts to renegotiate the trillion-dollar North American Free Trade Agreement between Canada, the United States and Mexico.

Trump blames the 1994 pact for U.S. manufacturing job losses to lower-cost Mexico.

Mexico is the largest export market for U.S. pork, the product likely being targeted for retaliatory tariffs more than any other commodity, said Gregg Doud, the chief agricultural negotiator for the office of the U.S. trade representative.

“We’ve got to get this NAFTA thing sorted out,” he told a room full hog farmers at an agricultural event in Iowa.

China has also imposed tariffs on U.S. pork and other products. It was the second-largest destination for U.S. pork by volume last year.

Trump has threatened tariffs on up to $150 billion worth of Chinese exports as part of a different dispute over Chinese intellectual property protections.

Separately, Trump has withdrawn from the multilateral Trans-Pacific Partnership promoted by Japan, the top destination for U.S. chilled and frozen beef. Europe is expected to become a bigger competitor to U.S. meat in Japan unless Washington strikes a new deal with Tokyo.

“I am very concerned about the situation with Japan,” Doud said.

A bright spot for U.S. pork is an agreement that allows U.S. pork exporters to ship meat to Argentina for the first time in 26 years, Doud said.

“These things now that we have to fix are very, very difficult,” he said. “This is going to get a little more difficult here in the short term.”

Ty Rosburg, who transports hogs for a living in Iowa and heard Doud speak, said he worried trade disputes could hurt the farmers who are his customers. Still, he said he believed U.S. officials were attempting to improve trade.

“I guess at some point you have to trust they’re working for the greater good and hope that we don’t get bit too bad,” he said.

CDC Reports Spike in US Suicide Rates

Suicide rates rose in nearly every U.S. state from 1999 to 2016, with the rate spiking by more than 30 percent in half of the country, the Centers for Disease Control and Prevention (CDC) reported Thursday.

Though mental health is often blamed for suicides, more than half of the people who took their own lives in 27 states in 2015 had not been diagnosed with mental illnesses, the CDC said.

While suicide rates rose across age groups, the CDC said people ages 45-64 had the biggest rate increase. That age group also had the highest rate. People ages 10-24 had the lowest rate.

“It’s a national problem of wide scope that we need comprehensive approaches for,” said Anne Schuchat, a CDC deputy director.

Nearly 45,000 people committed suicide in 2016, making it one of three leading causes of death on the rise in the United States, along with Alzheimer’s disease and drug overdoses.

The death of designer Kate Spade by suicide in New York this week shocked the fashion world. Her husband said in a statement Wednesday that she had suffered from depression and anxiety for many years.

The CDC said suicides were rarely caused by any single issue.

In addition to mental health conditions and suicide attempts as risk factors, other contributing circumstances include social and economic problems, access to the means to commit suicide, and poor coping and problem-solving skills, the health agency said in its Morbidity and Mortality Weekly Report.

The CDC found that suicides had increased in every state except Nevada, where they decreased by 1 percent. However, Nevada had the ninth-highest suicide rate in the country.

North Dakota had the highest increase, at nearly 58 percent over the studied time period.

Montana had the highest suicide rate, at 29.2 per 100,000 people per year, while the District of Columbia had the lowest, at 6.9 suicides per 100,000 people per year.

The CDC recommended a broad approach to suicide prevention, including boosting economic support by states, supporting family and friends after a suicide, and identifying and supporting people at risk for suicide.

Heat-Trapping Carbon Dioxide Levels in Air Hit Another High

The amount of heat-trapping carbon dioxide in the air peaked again this year at record levels, scientists reported Thursday.

The National Oceanic and Atmospheric Administration said Thursday that carbon dioxide levels averaged 411.25 parts per million in May at the federal Mauna Loa observatory in Hawaii, up from 409.65 a year ago.

The Scripps Institution for Oceanography, where scientists first started tracking the gas, found a similar increase.

May is traditionally the highest month for carbon dioxide levels; in late spring and summer, plants suck the heat-trapping gas out of the air.

The amount of carbon dioxide in the air has increased nearly 26 percent in 50 years. Burning coal, gas and oil emits carbon dioxide, which is a major greenhouse gas.

NOAA greenhouse gas monitoring chief Pieter Tans said the rate of increase from last year is a little less than past years but much more than it was in the 1990s.

“The emissions that we are causing today will still be in the atmosphere-ocean system thousands of years from now,” Tans said. “We are as a global society making an extremely long climate change commitment.”

Trump Says Working With Abe to Improve US-Japan Trade Relations

U.S. President Donald Trump said on Thursday after White House talks with Japanese Prime Minister Shinzo Abe that the two leaders were working together to improve trading relations and that Abe promised new Japanese investment in the United States.

At a joint news conference, Trump said Abe told him Japan was buying “billions and billions of dollars of additional products of all kinds – military jets, airliners from Boeing, lots of farm products.”

“We’re working hard to reduce our trade imbalance which is very substantial, remove barriers to U.S. exports and to achieve a fair and mutually beneficial economic partnership,” Trump said.

Japan, a key American ally, is among a number of countries hit by metal tariffs Trump has imposed this year. The Trump administration has also threatened levies on imports of Japanese cars.

Trump has made clear he prefers a bilateral deal to reduce the U.S. trade deficit with Japan, while Abe’s government says multilateral agreements would be best.

“The United States seeks a bilateral deal with Japan that is based on the principle of fairness and reciprocity,” Trump said on Thursday.

Abe said he had a detailed and candid exchange of views with Trump and the discussions focused on North Korea.

Trump said his administration encouraged Japanese investment in new plants in the United States.

“The prime minister told me that will happen,” he said. “We want new auto plants going into Michigan and Pennsylvania and Ohio.”

South Sudan and Sudan Agree to Repair Damaged Oil Infrastructure

South Sudan said Thursday it had agreed with its northern neighbor Sudan to repair oil infrastructure facilities destroyed by conflict within three months to boost production in Africa’s youngest country.

Michael Makuei Lueth, South Sudan’s information minister, told Reuters that officials agreed with their visiting Sudanese counterparts to “evaluate and assess the damage” to South Sudan’s oilfields in the Heglig area in the country’s north.

“There is an agreement between the two oil ministries of the two countries. They agreed to cooperate and work together in order to repair [the damage],” he said.

South Sudan depends virtually entirely on oil sales for its revenue but production has declined since war broke out in the country in 2013.

The oil is shipped to international markets via a pipeline through Sudan.

Fighting was triggered by a political disagreement between President Salva Kiir and his former deputy Riek Machar, and a regionally brokered peace pact failed to end the war after violations by both parties.

Officials from the two countries “agreed that within the period of three months they will repair all the oil blocks and resume oil production in the region,” he said referring to the infrastructure in the oil blocks.

The war has uprooted a quarter of South Sudan’s population of 12 million, ruined the country’s agriculture and battered the economy.

A joint force would also be established by both countries to protect the oilfields from attacks by rebel forces in South Sudan and Sudan.

NASA Rover Data Shows Mars Had Ingredients Needed for Life

A NASA rover has detected a bonanza of organic compounds on the surface of Mars and seasonal fluctuations of atmospheric methane in findings released on Thursday that mark some of the strongest evidence ever that Earth’s neighbor may have harbored life.

But National Aeronautics and Space Administration scientists emphasized there could be nonbiological explanations for both discoveries made by the Curiosity rover at a site called Gale crater, leaving the issue of Martian life a tantalizing but unanswered question.

Three different types of organic molecules were discovered when the rover dug just 2 inches (5 cm) into roughly 3.5 billion-year-old mudstone, a fine-grained sedimentary rock, at Gale crater, apparently the site of a large lake when ancient Mars was warmer and wetter than the desolate planet it is today.

Curiosity also measured an unexpectedly large seasonal cycle in the low levels of atmospheric methane. About 95 percent of the methane in Earth’s atmosphere is produced from biological activity, though the scientists said it is too soon to know if the Martian methane also is related to life.

Organic molecules are the building blocks of life, though they can also be produced by chemical reactions unrelated to life. The scientists said it is premature to know whether or not the compounds were created in biological processes.

Whether anywhere other than Earth has harbored life, perhaps even in microbial form, is one of the paramount questions in science.

“There’s three possible sources for the organic material,” said astrobiologist Jennifer Eigenbrode of NASA’s Goddard Space Flight Center in Maryland. “The first one would be life, which we don’t know about. The second would be meteorites. And the last one is geological processes, meaning the rock-forming processes themselves.”

The rover, which has allowed scientists to explore whether Mars ever boasted conditions conducive to life, in 2014 made the first definitive detection of organic molecules, also in Gale crater rock formed from ancient lake sediment — but it was a much more limited set of compounds.

“What the organic detections in the rock do is to add to the story of habitability. It tells us that this ancient environment on Mars could have supported life,” Eigenbrode said. “Everything that was needed to support life  was there. But it doesn’t tell us that life was there.”

Christopher Webster, an atmospheric science research fellow at NASA’s Jet Propulsion Laboratory in California, said it is possible existing microbes are contributing to the Martian atmospheric methane.

“With this new data, we again cannot rule out microbial activity as a potential source,” Webster said.

The amount of methane peaked at the end of summer in the northern hemisphere at about 2.7 times the level of the lowest seasonal amount.

The scientists were surprised to find organic compounds, especially in the amounts detected, considering the harsh conditions, including bombardment of solar radiation on the Martian surface. After drilling, Curiosity heats the rock samples, releasing the compounds.

Referring to the findings regarding organic compounds and methane, Webster said, “They hint at an earlier time on Mars when water was present and the existence of primitive life forms was possible.”

The scientists hope to find better preserved organic compounds with Curiosity or other rovers that would allow them to check for chemical signatures of life.

The research was published in the journal Science.

Hawaii Volcano Gives Experts Clues to Boost Science

Hawaii’s Kilauea volcano may be disrupting life in paradise with its bursts of ash and bright-orange lava, but it also has scientists wide-eyed, eager to advance what’s known about volcanoes.

The good news is: Volcanoes reveal secrets when they’re rumbling, which means Kilauea is producing a bonanza of information.

While scientists monitored Big Island lava flows in 1955 and 1960, equipment then was far less sophisticated. Given new technology, they can now gather and study an unprecedented volume of data.

“Geophysical monitoring techniques that have come online in the last 20 years have now been deployed at Kilauea,” said George Bergantz, professor of earth and space sciences at the University of Washington. “We have this remarkable opportunity … to see many more scales of behavior both preceding and during this current volcanic crisis.”

Starting May 3, Kilauea has fountained lava and flung ash and rocks from its summit, destroying hundreds of homes, closing key highways and prompting health warnings. Kilauea is one of five volcanos that form the Big Island, and is a “shield” volcano — built up over time as lava flows layer on top of layer.

Technically speaking, it has been continuously erupting since 1983. But the recent combination of earthquakes shaking the ground, steam-driven explosions at the top, and lava creeping into a new area some 12 miles (20 kilometers) from the summit represents a departure from its behavior over the past 35 years, said Erik Klemetti, a volcanologist at Ohio’s Denison University.

What’s happening now is a bit more like the Kilauea of nearly a century ago. In 1924, steam explosions at the summit lasted for more than two weeks.

Scientists are looking into what caused the change and whether this shift in the volcano’s magma plumbing system will become the new normal.

Radar allows researchers to measure the height of ash plumes shooting from the summit, even when they occur at night. Plume heights are an effect of how much heat energy is released and the explosion’s intensity.

“It’s one of the key factors that dictates how far ash will be dispersed,” said Charles Mandeville, volcano hazards coordinator for the U.S. Geological Survey. The other is where the winds are blowing. Such knowledge is useful in alerting the public.

Scientists can also monitor where gas is emerging, as well as determine its composition and volume. They can even measure the subtle rise and fall of the ground over a broad area and time — down to seconds — which suggests when and where magma is pooling underground.

Discovering variations or correlations between past and present activity provides more clues on what’s happening. It also helps scientists understand past lava flows, anticipate what could occur next, and pinpoint signs or patterns before an eruption.

“You’re sort of zeroing in on finer and finer levels of detail into how the volcano works,” said Michael Poland, a U.S. Geological Survey volcanologist. “The more stuff you put on the volcano to make measurements, the more you realize there’s stuff going on that you never knew.”

Better technology has also meant U.S. Geological Survey scientists have been able to accurately forecast Kilauea’s behavior as it sputters over Puna, the island’s most affected district.

“They’ve been spot on,” said Janine Krippner, a volcanologist at Concord University in West Virginia. “It’s incredible — they’re looking at things happening below the surface, using the monitoring equipment that they have, the knowledge they have of past eruptions, and have been able to get people to not be in a deadly area.”

This is unfortunately not always possible, as nature can be unpredictable. On June 3, Guatemala’s Volcano of Fire sent a mixture of hot gas, rock and other material racing down its slopes and inundating the valley, killing nearly 100 people.

Krippner compared the Guatemala eruption to opening a can of soda after shaking it vigorously. Volcanic gas underneath created bubbles that expanded, increasing pressure that blew magma apart when it reached the surface, spewing cooled lava rocks ranging from the size of sand grains to boulders.

Explosions can be bigger, or occur differently, than expected, and that presents a learning opportunity for scientists, who work on computer models to map out areas that may be at higher risk in the future. “Looking at the footage afterward, we can start to tease out how these things actually work,” Krippner said, as it’s often too dangerous for experts to physically get close to an eruption.

Volcanic eruptions happen fairly regularly — as many as 60 occur worldwide each year — but many are in isolated areas, according to the U.S. Geological Survey.

After Kilauea’s 1924 summit explosions, the volcano entered a decade of piddly rumblings, followed by 18 years of silence. Experts say Kilauea may be heading toward years — even decades — of little or no activity.

For now, volcanologists feel a “tremendous amount of responsibility” to learn as much as possible from the volcano, Poland said. Its latest activity has destroyed about 400 homes — including about 280 over the last several days — and displaced thousands of residents. Lava from Kilauea has also downed power lines and knifed across highways.

“It’s coming at a great cost in terms of impact on the lives and livelihoods of so many people — we owe it to the people of Puna to make sure that we learn the lessons the volcano is teaching us,” Poland said.

US, China Reach Deal to End Sanctions on Telecom Giant ZTE

The U.S. and China have reached a deal to lift sanctions against the giant Chinese ZTE telecommunications company that hobbled the firm when the United States banned the sale of American-made components it needed for its consumer products, U.S. Commerce Secretary Wilbur Ross said Thursday.

Ross told CNBC the accord will force ZTE, which employs nearly 75,000 workers, to pay a $1 billion fine for violating the U.S. ban on trade with North Korea and Iran, put another $400 million in escrow, and within 30 days replace its entire management and board.

Ross said going forward, the deal imposes the “most strict” compliance on ZTE. He said the penalties should serve as a very strong deterrent for “other potential bad actors” to force compliance with U.S. trade restrictions.

“If they do violate it again, in addition to the billion dollars they are paying us up front, we had them put $400 million in escrow,” he said. “The total deal is $1.4 billion. That money will be forfeited if they violate anything … and we still retain the power to shut them down again.”

ZTE must hire a new compliance team selected by the U.S. Commerce Department for a 10-year term.

“We are literally embedding a compliance department of our choosing into the company to monitor it going forward,” Ross said. “They will pay for those people, but the people will report to the new chairman.”

“This is a pretty strict settlement,” he added. “The strictest and largest settlement fine that has ever been brought by the Commerce Department against any violator of export controls.”

The commerce secretary said he did not think the settlement of the ZTE dispute would have any impact on ongoing contentious trade and tariff talks between the U.S. and China, the world’s two biggest economies.

Washington and Beijing have threatened each other with massive new tariffs on up to $150 billion of exports from the two countries, the fallout from the U.S. demand that China buy more American goods to sharply cut last year’s $375 billion Chinese trade surplus with the U.S.

The ZTE agreement was reached after weeks of talks between U.S. and Chinese officials. The dispute stemmed from a U.S. decision to block sales of American-made components ZTE needs to manufacture its products for seven years, until 2025. The agreement calls for a 10-year suspended ban that can be activated if ZTE commits new trade violations.

Most of the world first heard of the dispute over ZTE nearly a month ago following a tweet by U.S. President Donald Trump.

Some U.S. lawmakers, both Republicans and Democrats, balked at Trump’s effort to reach an accord on ZTE, saying that firm was a threat to U.S. national security through intelligence gathering on its devices. But Trump ignored the complaints, pushing Ross to settle the dispute.

Trump’s Solar Tariff Costs US Companies Billions

President Donald Trump’s tariff on imported solar panels has led U.S. renewable energy companies to cancel or freeze investments of more than $2.5 billion in large installation projects, along with thousands of jobs, the developers told Reuters.

That’s more than double the about $1 billion in new spending plans announced by firms building or expanding U.S. solar panel factories to take advantage of the tax on imports.

The tariff’s bifurcated impact on the solar industry underscores how protectionist trade measures almost invariably hurt one or more domestic industries for every one they shield from foreign competition. 

Trump announced the tariff in January over protests from most of the solar industry that the move would chill one of America’s fastest-growing sectors.

​Utility-scale projects

Solar developers completed utility-scale installations costing a total of $6.8 billion last year, according to the Solar Energy Industries Association. Those investments were driven by U.S. tax incentives and the falling costs of imported panels, mostly from China, which together made solar power competitive with natural gas and coal.

The U.S. solar industry employs more than 250,000 people, about three times more than the coal industry, with about 40 percent of those people in installation and 20 percent in manufacturing, according to the U.S. Energy Information Administration.

“Solar was really on the cusp of being able to completely take off,” said Zoe Hanes, chief executive of Charlotte, North Carolina solar developer Pine Gate Renewables.

Companies with domestic panel factories are divided on the policy. Solar giant SunPower Corp opposes the tariff that will help its U.S. panel factories because it will also hurt its domestic installation and development business, along with its overseas manufacturing operations.

“There could be substantially more employment without a tariff,” said Chief Executive Tom Werner.

​Lost profits, jobs

The 30 percent tariff is scheduled to last four years, decreasing by 5 percent per year during that time. Solar developers say the levy will initially raise the cost of major installations by 10 percent.

Leading utility-scale developer Cypress Creek Renewables LLC said it had been forced to cancel or freeze $1.5 billion in projects, mostly in the Carolinas, Texas and Colorado, because the tariff raised costs beyond the level where it could compete, spokesman Jeff McKay said.

That amounted to about 150 projects at various stages of development that would have employed 3,000 or more workers during installation, he said. The projects accounted for a fifth of the company’s overall pipeline.

Developer Southern Current has made similar decisions on about $1 billion of projects, mainly in South Carolina, said Bret Sowers, the company’s vice president of development and strategy.

“Either you make the decision to default or you bite the bullet and you make less money,” Sowers said.

Neither Cypress Creek nor Southern Current would disclose exactly which projects they intend to cancel. They said those details could help their competitors and make it harder to pursue those projects if they become financially viable later.

Both are among a group of solar developers that have asked trade officials to exclude panels used in their utility-scale projects from the tariffs. The office of the U.S. Trade Representative said it is still evaluating the requests.

Other companies are having similar problems.

Stockpiling panels

For some developers, the tariff has meant abandoning nascent markets in the American heartland that last year posted the strongest growth in installations. That growth was concentrated in states where voters supported Trump in the 2016 presidential election.

South Bend, Indiana-based developer Inovateus Solar LLC, for example, had decided three years ago to focus on emerging Midwest solar markets such as Indiana and Michigan. But the tariff sparked a shift to Massachusetts, where state renewable energy incentives make it more profitable, Chairman T.J. Kanczuzewski said.

Some firms saw the tariff coming and stockpiled panels before Trump’s announcement. For example, 174 Power Global, the development arm of Korea’s Hanwha warehoused 190 megawatts of solar panels at the end of last year for a Texas project that broke ground in January.

The company is paying more for panels for two Nevada projects that start operating this year and next, but is moving forward on construction, according to Larry Greene, who heads the firm’s development in the U.S. West.

‘A lot of robots’

Trump’s tariff has boosted the domestic manufacturing sector as intended, which over time could significantly raise U.S. panel production and reduce prices.

Panel manufacturers First Solar and JinkoSolar , for example, have announced plans to spend $800 million on projects to increase panel construction in the United States since the tariff, creating about 700 new jobs in Ohio and Florida. Last week, Korea’s Hanwha Q CELLS joined them, saying it will open a solar module factory in Georgia next year, though it did not detail job creation.

SunPower Corp, meanwhile, purchased U.S. manufacturer SolarWorld’s Oregon factory after the tariff was announced, saving that facility’s 280 jobs. The company said it plans to hire more people at the plant to expand operations, without specifying how many.

But SunPower has also said it must cut up to 250 jobs in other parts of its organization because of the tariffs.

Jobs in panel manufacturing are also limited because of increasing automation, industry experts said.

Heliene, a Canadian company in the process of opening a U.S. facility capable of producing 150 megawatts worth of panels per year, said it will employ between 130 and 140 workers in Minnesota.

“The factories are highly automated,” said Martin Pochtaruk, president of Heliene. “You don’t employ too many humans. There are a lot of robots.

Blockchain Advances Could Revolutionize Daily Life

As the internet continues to revolutionize communications, the next world-changing technology may already be here. Blockchain, a way of recording data and automatically storing it on computers around the world, has the potential to change everything from collecting crime scene evidence to creating new digital currencies. VOA’s Jill Craig visited a blockchain hackathon in Memphis, Tennessee, to learn more.
