NAIROBI, Kenya — The impact of the calamitous rains that struck East Africa from March to May was intensified by a mix of climate change and rapid growth of urban areas, an international team of climate scientists said in a study published Friday. The findings come from World Weather Attribution, a group of scientists that analyzes whether and to what extent human-induced climate change has altered the likelihood and magnitude of extreme weather events. The downpours caused floods that killed hundreds of people, displaced thousands of others, killed thousands of livestock and destroyed thousands of acres of crops. To assess how human-caused climate may have affected the floods, the researchers analyzed weather data and climate model simulations to compare how these types of events have changed between today’s climate and the cooler pre-industrial one. They focused on regions where the impacts were most severe, including southern Kenya, most of Tanzania and …

SEQUOIA NATIONAL PARK, California — High in the evergreen canopy of General Sherman, the world’s largest tree, researchers searched for evidence of an emerging threat to giant sequoias: bark beetles. The climbers descended the towering 2,200-year-old tree with good news on Tuesday. “The General Sherman tree is doing fine right now,” said Anthony Ambrose, executive director of the Ancient Forest Society, who led the expedition. “It seems to be a very healthy tree that’s able to fend off any beetle attack.” It was the first time climbers had scaled the iconic 85-meter sequoia tree, which draws tourists from around the world to Sequoia National Park. Giant sequoias, the Earth’s largest living things, have survived for thousands of years in California’s western Sierra Nevada range, the only place where the species is native. But as the climate grows hotter and drier, giant sequoias previously thought to be almost indestructible are increasingly threatened …

WASHINGTON — Get ready for what nearly all the experts think will be one of the busiest Atlantic hurricane seasons on record, thanks to unprecedented ocean heat and a brewing La Nina.  There’s an 85% chance that the Atlantic hurricane season starting in June will be above average in storm activity, the National Oceanic and Atmospheric Administration announced Thursday in its annual outlook. The weather agency predicted between 17 and 25 named storms will brew up this summer and fall, with eight to 13 achieving hurricane status (at least 75 mph sustained winds) and four to seven of them becoming major hurricanes, with at least 111 mph winds.  An average Atlantic hurricane season produces 14 named storms — seven of them hurricanes and three major hurricanes.  “This season is looking to be an extraordinary one in a number of ways,” NOAA Administrator Rick Spinrad said. He said this forecast is the …

New York — A Michigan dairy worker has been diagnosed with bird flu — the second human case associated with an outbreak in U.S. dairy cows.  The patient had mild eye symptoms and has recovered, U.S. and Michigan health officials said in announcing the case Wednesday. The worker had been in contact with cows presumed to be infected, and the risk to the public remains low, officials said.  A nasal swab from the person tested negative for the virus, but an eye swab tested positive, “indicating an eye infection,” the U.S. Centers for Disease Control and Prevention said in a statement.  The first case happened in late March, when a farmworker in Texas was diagnosed in what officials called the first known instance globally of a person catching this version of bird flu from a mammal. That patient also reported only eye inflammation and recovered.  Since 2020, a bird flu virus …

Experts say that in Ukraine, there has been a heavy increase in cases of anxiety, depression, adjustment disorder, post-traumatic stress disorder and other mental health problems since Russia’s invasion in 2022, and it will likely have a long-term impact. For VOA, Lesia Bakalets has more. …

BERLIN — A group of small island states that include Antigua and Barbuda and the Bahamas secured a win on climate change in an international court Tuesday as they seek to combat rising sea levels. In its first climate-related judgment, the International Tribunal for the Law of the Sea, or ITLOS, said that greenhouse gas emissions absorbed by the ocean are considered marine pollution and countries are obliged to protect marine environments by going further than required under the Paris climate agreement. The opinion was requested by a group of nine island nations facing climate-driven rises in sea levels. The opinion is not legally binding, but it can be used to help guide countries in their climate policy and, in other cases, as legal precedent. “The ITLOS opinion will inform our future legal and diplomatic work in putting an end to inaction that has brought us to the brink of an …

LONDON — Countries raised a record $104 billion last year by charging firms for emitting carbon dioxide, but prices remain too low to drive changes needed to meet Paris climate accord targets, the World Bank said in a report on Tuesday.   Several countries are using a price on carbon emissions to help meet their climate goals by making polluters pay in the form of a tax, or under an emissions trading (ETS), or cap-and-trade, system. “Carbon pricing is a critical part of the policy mix needed to both meet the Paris Agreement goals and support low emissions growth,” the World Bank’s State and Trends of Carbon Markets report said.   There are 75 global carbon pricing instruments in operation, up two from a year ago, covering around 24% of global greenhouse gas emissions. The figure raised in 2023 in carbon revenues was up from around $95 billion raised in 2022. …

Paris — Climate change played a key role in last year’s record-low levels of Antarctic sea ice, a study published on Monday found, marking an abrupt shift from the growth seen in previous decades. Scientists from the British Antarctic Survey (BAS) found that human-caused global warming resulted in a once-in-2,000-year low in ocean surface around the continent blanketed by ice. Compared to an average winter over the last several decades, the maximum extent of Antarctic sea covered by ice shrank by two million square kilometers — an area four times the size of France, the BAS said. “This is why we were so interested in studying what climate models can tell us about how often large, rapid losses like this are likely to happen,” the study’s lead author Rachel Diamond told AFP. Scientists, having analyzed 18 distinct climate models, found that climate change quadrupled the likelihood of such large and rapid …

London — The final report of the U.K.’s infected blood inquiry will be published Monday, nearly six years after it began looking into how tens of thousands of people contracted HIV or hepatitis from transfusions of tainted blood and blood products in the 1970s and 1980s. The scandal is widely seen as the deadliest to afflict Britain’s state-run National Health Service since its inception in 1948, with around 3,000 people believed to have died as a result of being infected with HIV and hepatitis, an inflammation of the liver. The report is expected to criticize pharmaceutical firms and medical practitioners, civil servants and politicians, although many have already died given the passage of time. It’s also set to pave the way to a huge compensation bill that the British government will be under pressure to rapidly pay out. Had it not been for the tireless campaigners, many of whom saw loved …

Washington — After a nearly two year hiatus, Blue Origin flew adventurers to space on Sunday including a former Air Force pilot who was denied the chance to be the United States’ first Black astronaut decades ago.    It was the first crewed launch for the enterprise owned and founded by Amazon billionaire Jeff Bezos since a rocket mishap in 2022 left rival Virgin Galactic as the sole operator in the fledgling suborbital tourism market.    Six people including the sculptor Ed Dwight, who was on track to become NASA’s first ever astronaut of color in the 1960s before being controversially spurned, launched around 09:36 am local time (1436 GMT) from the Launch Site One base in west Texas, a live feed showed.    Dwight — at 90 years, 8 months and 10 days — became the oldest person to ever go to space.    “This is a life-changing experience, everybody needs to …
