Heat waves, intensified by climate change, have cost the global economy trillions of dollars in the past 30 years, a study published Friday found, with poor countries paying the steepest price.

And those lopsided economic effects contribute to widening inequalities around the world, according to the research. 

“The cost of extreme heat from climate change so far has been disproportionately borne by the countries and regions least culpable for global warming,” Dartmouth College professor Justin Mankin, one of the authors of the study published in the journal Science Advances, told AFP. “And that’s an insane tragedy.”

“Climate change is playing out on a landscape of economic inequality, and it is acting to amplify that inequality,” he said.

Periods of extreme heat cost the global economy about $16 trillion between 1992 and 2013, the study calculated. 

But while the richest countries have lost about 1.5% of their annual per capita GDPs dealing with heat waves, poorer countries have lost about 6.7% of their annual per capita GDPs. 

The reason for that disparity is simple: poor countries are often situated closer to the tropics, where temperatures are warmer anyway. During heat waves, they become even hotter.

The study comes just days ahead of the start of the COP27 climate summit in Egypt, where the question of compensation for countries that are disproportionately vulnerable to but least responsible for climate change is expected to be one of the key topics. 

The costs of heat waves come from several factors: effects on agriculture, strains on health systems, less productive workforces and physical damage to infrastructure, such as melting roads. 

Study researchers examined five days of weather considered extreme for a specific region each year. 

“The general idea is to use variation in extreme heat, which is effectively randomly assigned to all these economic regions and see the extent to which that accounts for variation in economic growth” in a given region, Mankin explained. 

“Then the second part is to say, ‘OK, how has human-caused warming influenced extreme heat?'” he added.

Despite these calculations, the study results almost certainly underestimate the true cost of extreme heat, according to the paper — only studying five days per year does not reflect the increased frequency of such heat events, and not all potential costs were included. 

Previous studies on the subject had focused on the costs of heat to specific sectors, though scientists say it is important to look at the price tag of climate change wholistically. 

“You want to know what those costs are, so that you have a frame of reference against which to compare the cost of action,” Mankin said, such as establishing cooling centers or installing air conditioners, versus “the cost of inaction.”

“The dividends economically of responding to the five hottest days of the year could be quite great,” he said.

But according to Mankin, the most important response is to reduce carbon emissions to slow global warming at the source. 

“We need to adapt to the climate we have now, and we also need to deeply invest in mitigation,” he said.

YouTube announced Thursday it wants to help people make informed health care decisions by allowing more medical sources to share videos on its platform.  

“At YouTube, we’re working to make it easier for people to find authoritative information to help answer their questions, and we’re putting health professionals at the core of our efforts to connect people with helpful content,” the company said on its website. 

Doctors, nurses, and other health care professionals can now apply to have their video channels certified to participate in You Tube’s health features, something that, until now, has only been available to educational institutions, public health departments, hospitals and government entities.

“The reality is that the majority of healthcare decisions are made outside the doctor’s office, in the everyday lives of our patients,” YouTube said.  “That’s why YouTube Health has been working on additional ways to help doctors, nurses, mental health professionals and health care information providers to bring high quality health information into the spaces that people visit throughout their day – like their favorite video-sharing app. 

“This new step will allow us to expand to include high quality information from a wider group of health care channels,” the company said.

YouTube has been criticized in the past for being home to some misinformation about COVID-19 vaccines but has since banned the misleading information.

Tuberculosis case numbers increased from 2019 to 2021, reversing years of progress as the COVID-19 pandemic disrupted access to treatment and testing, the World Health Organization said Thursday. 

“For the first time in nearly two decades, WHO is reporting an increase in the number of people falling ill with TB and the drug-resistant tuberculosis, alongside an increase in TB related deaths,” said Tereza Kasaeva, director of the U.N. health agency’s global TB program. 

A WHO report released Thursday stated that more than 10 million people got tuberculosis in 2021, a 4.5% increase from 2020. Roughly 450,000 cases involved individuals infected with the drug-resistant TB strain, a 3% increase from 2020 to 2021. Most of these cases were reported in India, Indonesia, Myanmar and the Philippines.

The COVID-19 pandemic “continues to have a damaging impact on access to TB diagnosis and treatment,” WHO said. COVID-19 restrictions, such as lockdowns and physical distancing, resulted in fewer people being diagnosed and getting the necessary treatment. With fewer people being diagnosed and treated for TB, more patients unknowingly spread the disease to others. As a result, more than a decade of progress was lost, said Dr. Mel Spigelman, president of the nonprofit TB Alliance. 

Tuberculosis is caused by bacteria that attack the lungs. The disease is mainly spread through the air and, after COVID-19, tuberculosis is the world’s deadliest infectious disease. It primarily affects adults, particularly those who are malnourished or immunocompromised, in developing countries. More than 95% of cases are in developing countries.

The downturn of the global economy during the pandemic worsened the problem, as families faced unbearable costs due to their treatment, especially in developing countries. 

Dr. Hannah Spencer, with Doctors Without Borders in South Africa, suggested lowering the prices of tuberculosis treatment to no more than $500 to help low-income patients. WHO also suggested that more countries should cover the cost of TB diagnosis and treatment. 

“If the pandemic has taught us anything, it’s that with solidarity, determination, innovation and the equitable use of tools, we can overcome severe health threats,” WHO Director-General Tedros Adhanom Ghebreyesus said in a news release Thursday. “Let’s apply those lessons to tuberculosis. It is time to put a stop to this long-time killer.”

Hawaii officials are warning residents of the Big Island that the world’s largest active volcano, Mauna Loa, is sending signals that it may erupt.

Scientists say an eruption isn’t imminent, but they are on alert because of a recent spike in earthquakes at the volcano’s summit. Experts say it would take just a few hours for lava to reach homes closest to vents on the volcano, which last erupted in 1984.

Hawaii’s civil defense agency is holding meetings across the island to educate residents about how to prepare for a possible emergency. They recommend having a “go” bag with food, identifying a place to stay once they leave home and making a plan for reuniting with family members.

“Not to panic everybody, but they have to be aware of that you live on the slopes of Mauna Loa. There’s a potential for some kind of lava disaster,” said Talmadge Magno, the administrator for Hawaii County Civil Defense.

The volcano makes up 51% of the Hawaii Island landmass, so a large portion of the island has the potential to be affected by an eruption, Magno said.

There’s been a surge of development on the Big Island in recent decades — its population has more than doubled to 200,000 today from 92,000 in 1980 — and many newer residents weren’t around when Mauna Loa last erupted 38 years ago. All the more reason why Magno said officials are spreading the word about the science of the volcano and urging people to be prepared.

Mauna Loa, rising 13,679 feet (4,169 meters) above sea level, is the much larger neighbor to Kilauea volcano, which erupted in a residential neighborhood and destroyed 700 homes in 2018. Some of its slopes are much steeper than Kilauea’s so when it erupts, its lava can flow much faster.

During a 1950 eruption, the mountain’s lava traveled 15 miles (24 kilometers) to the ocean in less than three hours.

The Hawaiian Volcano Observatory, which is part of the U.S. Geological Survey, said Mauna Loa has been in a state of “heightened unrest” since the middle of last month when the number of summit earthquakes jumped from 10 to 20 per day to 40 to 50 per day.

Scientists believe more earthquakes are occurring because more magma is flowing into Mauna Loa’s summit reservoir system from the hot spot under the earth’s surface that feeds molten rock to Hawaii’s volcanoes.

The temblors have declined in frequency in recent days but could rise again.

More than 220 people attended a community meeting last weekend that county civil defense officials held in Ocean View, a neighborhood that lava could reach in hours if molten rock erupts through vents on Mauna Loa’s southwest flank.

Bob Werner, an Ocean View resident who didn’t attend the meeting, said it’s wise to be aware of a possible eruption but not to fear it. He’s not concerned that the neighborhood would be completely cut off, if lava flows across the only road connecting it to the bigger towns of Kailua-Kona and Hilo, where many people do their shopping.

The “greater concern is it will be extremely annoying to drive an extra hour or two hours to get the same stuff,” he said.

Ryan Williams, the owner of the Margarita Village bar in Hilo, said the volcanic unrest wasn’t worrying customers who are used to warnings.

There could still be a heightened sense of urgency since officials have been holding town hall meetings, urging people to prepare.

“But everything I’ve read or heard, they trying to kind of assure people that conditions have not changed,” Williams said. “There’s no imminent eruption, but just to be alert.”

Magno said his agency is talking to residents now because communities closest to vents likely wouldn’t have enough time to learn how to respond and prepare once the observatory raises its alert level to “watch,” which means an eruption is imminent.

The current alert level is “advisory” meaning the volcano is showing signs of unrest yet there’s no indication an eruption is likely or certain.

Residents in other parts of the island would have more time to react.

Lava from Mauna Loa’s northeast flank could take days or weeks to reach residential communities. That’s because the mountain’s slopes on that side are relatively gentle and because towns are farther from volcanic vents.

Frank Trusdell, research geologist at the Hawaiian Volcano Observatory, said all of Mauna Loa’s eruptions in recorded history have started in its summit crater. About half of them stayed there, while the other half later spewed lava from vents lower down the mountain.

Lava erupting from the summit generally doesn’t travel far enough to reach residential areas.

Mauna Loa has erupted 33 times since 1843. It last erupted in 1984 when lava flowed down its eastern flank only to stop 4.5 miles (7.2 kilometers) short of Hilo, the Big Island’s most populous town.

Mauna Loa also has a history of disgorging huge volumes of lava.

In the 1950 eruption, which lasted for 23 days, Mauna Loa released 1,000 cubic meters (1,307 cubic yards) of lava per second. In contrast, Kilauea released 300 cubic meters (392 cubic yards) per second in 2018.

The earthquakes could continue for a while before any eruption: increased seismic activity lasted for a year before a 1975 eruption and a year-and-a-half before the 1984 one. Alternatively, the temblors could subside and Mauna Loa may not erupt this time.

Trusdell said residents should look at his agency’s maps and learn how quickly lava may show up in their neighborhood. He also urged people living in one of the short-notice areas to pay attention if the summit turns red.

“All you got to do is look up there and see the glow. You grab your stuff, throw it in the car and drive. Go!” he said.

They can always go home after if the lava ultimately doesn’t flow into their neighborhood, he said.

GENEVA – A U.N. report warns the window for preventing a climate catastrophe is fast closing. The U.N. Environment Program’s latest Emissions Gap Report urges unprecedented cuts in greenhouse gas emissions and a rapid transformation of societies to head off the worst.

The U.N. report finds the world is falling far short of the Paris climate goals agreement, with no credible pathway for limiting a temperature rise to 1.5 degrees Celsius by the end of the century.

UNEP Executive Director Inger Andersen said progress since last year’s climate change conference, COP 26 in Glasgow, Scotland, has been woefully inadequate. She said nations have failed to deliver on their pledges for greater emissions cuts.

She noted greenhouse gas emissions must be cut by 45 percent by 2030 to stop climate change. However, instead of stabilizing global temperatures at 1.5 degrees above the pre-industrial level, she said temperatures will likely rise 2.4 to 2.6 degrees by 2100.

“We are sliding from climate crisis to climate disaster. This report is sending us a very, very clear message. If we are serious about climate change, we need to kickstart a system-wide transformation now. We need a root and branch redesign of the electricity sector, of the transport sector, of the building sector, and food systems.”

Additionally, she said financial systems must be reformed so they can bankroll the required transformations. She says incremental changes no longer are an option. Bold action must be taken now.

Secretary-General of the World Meteorological Organization Peterri Talaas called the transformational changes doable. He noted the IPCC, Intergovernmental Panel on Climate Change, earlier this year reported that prices of climate-friendly energy solutions have been dropping.

“Nowadays, it is cheaper to invest in solar or wind energy as compared to the fossil energy. And the good news is also that 32 countries have reduced their emissions during the past 15 years, whereas their economies have been growing. So, there is not an automatic connection between economic growth and emissions growth.”

He mentioned European countries, the United States, Japan, and Singapore as some of the countries that have managed to grow their economies while reducing emissions.

Environmental experts estimate a global transformation to a low-emissions economy is expected to require investments of at least $4 trillion to $6 trillion a year. They are urging nations attending next week’s COP27 in Sharm el-Sheikh, Egypt, to agree to foot the bill and to up their pledges to cut greenhouse gas emissions.

The charity Doctors Without Borders said Thursday that Kenya’s Dadaab Refugee Complex faces a high risk of measles and cholera outbreaks as thousands of new refugees arrive from areas of Somalia where the diseases are circulating. 

More than 233,000 refugees live in three overcrowded camps in the complex.  

Doctors Without Borders, best known by its French acronym MSF, reported a sharp rise since January in the number of people fleeing to Kenya to escape drought, hunger and violence. 

Many of the new arrivals are from southern Somalia, where measles and cholera outbreaks recently have occurred, the charity said.  

MSF’s deputy program manager for Kenya, Adrian Guadarrama, said Thursday in Geneva that many are being received by refugee communities inside camps, but many more are living in very poor conditions on the outskirts of the camps. 

Last week, he said, MSF teams recorded three cases of measles and two suspected cases of cholera in Dagahaley, one of Dadaab’s three refugee camps. 

“This should be an alarm for all the actors and stakeholders involved in the response in Dadaab. Because we know that just one case of any of these diseases can cause a full-blown outbreak very quickly, affecting not only the refugee community, but also the host community,” Guadarrama said. 

Kenya’s Health Ministry last week issued a cholera alert following confirmation of 61 cases in six counties. 

Guadarrama said Kenya stopped registering new arrivals in Dadaab in 2015.  

Unregistered refugees, he said, cannot get basic services and assistance. He said clean drinking water is scarce, and toilets and handwashing points lacking. These conditions, he said, make the unregistered refugees highly vulnerable to life-threatening diseases. 

Guadarrama said the need for measles and cholera vaccination campaigns is urgent, but that devising a strategy is complex. Some people are scattered in the outskirts, he said, while others are inside Dagahaley camp. 

“We talk about a camp of 115,000. So, just to identify them is quite a challenge,” he said. “And this is why having screening, or a reception center or a registration center — that would be ideal — would allow us to cope with those activities and provide access to basic services including vaccination, for example.” 

Guadarrama said the humanitarian situation in the camps and in the surrounding communities is not yet at the breaking point and there is still time to avoid an emergency in a long and protracted crisis.

Germany on Wednesday unveiled plans to legalize cannabis, potentially making it one of the first countries in Europe to make marijuana legal.

Presenting his plans to the cabinet of Chancellor Olaf Scholz, German Health Minister Karl Lauterbach said the proposal aims to achieve “the most liberal cannabis liberalization in Europe, and, on the other hand … the most tightly regulated market.”

Germany’s federal Cabinet reportedly approved the plan, kicking off a lengthy process to legalize growth, cultivation and distribution of the plant.

German laws must comply with European legislation, and under the proposal, the government would regulate cannabis production, sale, and distribution as part of a controlled, legalized market, said Lauterbach, describing the reform as a possible “model” for other European countries.

Although many European countries have decriminalized small amounts of cannabis for recreational purposes, only one, Malta, has fully legalized it.

The proposed plan would also legalize the acquisition and possession of 20 to 30 grams of cannabis for personal consumption, cultivation of up to two or three plants per person, and sales through specialized stores. Use of cannabis would remain prohibited for anyone under 18.

According to the plan, the government would also introduce a special consumption tax and develop education and abuse prevention programs, while ongoing investigations and criminal proceedings connected to cannabis would be terminated.

Legalizing cannabis would push out Germany’s cannabis black market and could increase annual tax revenues, create 27,000 new jobs, and generate cost savings of about $4.7 billion, according to a report by Reuters.

Wednesday’s announcement was met with mixed reactions throughout the country. A national pharmacists association warned of potential health risks of legalizing cannabis, while some regional officials expressed concerns that Germany would become a drug-tourism destination, similar to the Netherlands, where some coffee shops are allowed to sell cannabis under strict conditions.

According to The Guardian, Germany’s health minister said the Dutch system “combined two disadvantages: liberal use but not a controlled market. What we have learned from the Dutch experience is that we don’t want to do it that way. We want to control the entire market.”

After two years of low influenza case numbers during the COVID-19 pandemic, the U.S. Centers for Disease Control and Prevention warns of a possibly harsh flu season.  

“The United States has experienced relatively little influenza activity since 2020, thanks, in part, to community mitigation measures used to control the spread of COVID-19, making the country ripe for a severe influenza season,” the CDC told VOA in an email.  

According to the CDC, the flu is already spreading in parts of the South, with relatively high activity levels in Georgia and Texas, compared to the same period last year.  

Although the influenza season in the U.S. is just beginning, “based on what we have seen in parts of the Southern Hemisphere, flu has the potential to hit us hard this year,” Dr. William Schaffner, medical director of the National Foundation for Infectious Diseases, said earlier this month.

Researchers often look to the Southern Hemisphere because its flu season hits first, usually from May to October, to foreshadow what will happen in the north, where flu season usually starts in October, peaks in December and can last through May. 

Australia’s flu season hit that country two months earlier than usual and caused one of its worst seasons in recent years, with cases peaking about three times higher than average, according to the Australian government’s Department of Health and Aged Care. During Australia’s 2022 flu season, of the 225,332 laboratory-confirmed cases, there have been 308 influenza-associated deaths, the agency reported. In comparison, in 2020, of the 21,266 laboratory-confirmed cases, there were 37 influenza-associated deaths. 

The flu hit younger people especially hard in Australia. Although COVID-19 has been relatively mild for younger people, experts caution that children may be at especially high risk this year. That’s because many children have not been exposed to the flu due to COVID-19 safety precautions, including the use of masks, remote learning and social distancing taken in recent years, leaving them without natural immunity. 

Influenza A, which causes more serious illness than other strains of the virus, is more prevalent this year, according to CDC data. It also spreads about two to three times more rapidly than Influenza B, a less common type of influenza.  

Although influenza symptoms are similar to those of a common flu, they are typically more intense and begin more abruptly. The symptoms include common cold symptoms, such as a cough or runny nose, but also range to symptoms such as a fever or body aches. Some people also experience vomiting or diarrhea, although this is more common in children than adults.  

The CDC urges that Americans ages 6 months and older get a flu shot by the end of October. Experts say it’s the best way to be protected from the ailment. 

“Over the past two years, we’ve seen some worrisome drops in flu vaccination coverage, especially in some groups of people who are at the highest risk of developing serious flu illness,” CDC Director Dr. Rochelle Walensky said during a news conference earlier this month.  

Health officials fear fewer people will be vaccinated because of the anti-vaccine sentiment that increased during the COVID-19 pandemic. A survey by the National Foundation for Infectious Diseases found that fewer Americans said they will get the flu shot compared to years before.  

The CDC told VOA News in an email that to help avoid the flu, “people should continue to practice the everyday preventive actions that we saw work so well during the pandemic like social distancing, frequent handwashing, staying home when you are sick, and covering coughs and sneezes.”   

“With a potentially challenging flu season ahead, I urge everyone to protect themselves and their families from flu and its potentially serious complications,” Walensky said.

Bees pollinate 71 of the 100 crop species that provide 90% of food worldwide. They also pollinate wild plants, helping sustain biodiversity and the beauty of the natural world.

But climate change, pesticides and parasites are taking a terrible toll on bees, and they need protecting, said European beekeepers, who held their annual congress in Quimper, western France, this week.

The congress, which said some European beekeepers were suffering “significant mortalities and catastrophic harvests due to difficult climatic conditions,” was an opportunity for beekeepers and scientists to respond to the major concerns.

The European Union, the world’s second-largest importer of honey, currently produces just 60% of what it consumes.

French beekeepers, for example, expect to harvest between 12,000 and 14,000 metric tons of honey this year, far lower than the 30,000 tons they harvested in the 1990s, according to the National Union of French Beekeepers (UNAF).

“I’ve been fighting for bees for 30 years, but if I had to choose now, I don’t know if I’d become a beekeeper,” said UNAF spokesman Henri Clement, who has 200 hives in the mountainous Cevennes region in southeastern France.

Clement is 62 and not far off retiring.

“But it’s not much fun for young people who want to take up the profession,” he said.

Many of the topics buzzing around the congress were evidence of this — pesticides, climate change, and Asian hornets, parasitic varroa mites and hive beetles, all invasive alien species in Europe.

Challenges includes rain, drought

With climate change, “the bigger issue is just the erratic weather and rain patterns, drought and things like that,” said U.S. entomologist Jeff Pettis, president of Apimondia, an international federation of beekeeping associations in 110 countries.

“In certain places, the plants had been used to a certain temperature. And now it goes up, and you have a hot dry summer, and there are no flowers,” Pettis told AFP.

No flowers means no pollen, which means bees dying of hunger.

Climate scientists say human-induced global heating is intensifying extreme weather events such as flooding, and heatwaves that exacerbate wildfires.

“The fires seem to be a big issue,” Pettis said. “They come sporadically, and we lose hives directly from flooding and fires.

Pettis, a former scientist at the U.S. Department of Agriculture, published a study in 2016 on the quality of pollen produced by goldenrod, a hardy perennial also known as solidago that produces a myriad of small yellow daisy-like flowers.

The study showed that the more carbon dioxide — a greenhouse gas — that accumulates in the atmosphere, the lower the amount of protein in goldenrod pollen.

North America bees are dependent on nourishment from goldenrod pollen to get through the winter, Pettis said.

“Getting inferior food … should affect wintering. It could happen with other pollen sources. We don’t know.”

As in France, 30% to 40% of hives in the United States are dying every winter, Pettis said, decimated by varroa mites, pesticides and the destruction of wild spaces where wild plants grow

“Today, there are even American startups that are developing drones to pollinize plants in the place of bees. It’s utterly appalling,” said Clement.

Toxic threat

Toxic pesticides are another factor decimating bee colonies and other pollinating insects.

French molecular biophysics scientist Jean-Marc Bonmatin said parasites such as varroa were “boosted by the presence of neonicotinide pesticides, which directly poison pollinators.”

Neonicotinoids, chemically similar to nicotine, are systemic pesticides.

Unlike contact pesticides, which remain on the surface of the treated leaves, systemic pesticides are taken up by the plant and transported to its leaves, flowers, roots and stems, as well as to its pollen and nectar.

These toxic substances can remain in the soil for between five and 30 years, Bonmatin said.

The EU restricted the use of three neonicotinoids — but not all — in 2013 and banned them outright in 2018.

But since 2013, several EU states have repeatedly granted “emergency authorizations” to use noxious insecticides on major crops.

He said open-source software called Toxibee was being launched soon to help farmers protect bees by identifying the least toxic molecules to use on their crops.

“Before they spray the crops with pesticides, they can try to limit their noxious effect,” he said. “Because what kills bees will one day damage people’s health, too.”

Pettis strove, however, to remain upbeat, pointing to some of the ways people can help bees.

“[We should] diversify agriculture and try not [to] be driven by chemically dependent agriculture, support organic and more sustainable farming.”

He also stressed the incredible resistance of some bee species, helped by factors in the natural world.

He cited the example of a black bee found on the Ile de Groix in Brittany, which has survived varroa attacks without beekeepers treating them for mites or giving them supplementary feeding.

“We think the bees are dependent on us, but in reality, they survive pretty well even without us,” he said. “And you still have the beauty of the bees. It’s such a good thing to work with bees.”
