Trump demands review of scientific manual used by federal judges

By -
By Benjamin S. Weiss , Courthouse News Service.  Excerpt: The president said the government-backed compendium of scientific and technological information, used to help judges ruling on complex cases, has been “totally discredited” and accused its authors of misleading the courts on climate change. ...Writing in a post on his social media platform Truth Social on Sunday evening, Trump said he had ordered “federal suspension and debarment officials” to review the National Academy of Sciences’ “Reference Manual on Scientific Evidence,” [RMSE] a decades-old publication produced in partnership with the Federal Judicial Center and aimed at assisting federal judges on issues of science and technology. ...The latest edition of the judicial reference manual, published late last year, included a chapter on climate science and climate change. ...But in February, the Federal Judicial Center, the government’s education and research agency serving federal courts, said it had removed the climate ...

Climate scientists sharpen tools for linking global warming to extreme weather

By -
By Julia Vaz , Science.  Excerpt: June’s European heat wave, in which temperatures above 40°C led to the deaths of more than 10,000 people, made headlines not just for its severity, but for what it said about climate change. Last week, a group called World Weather Attribution (WWA) linked it firmly to global warming, saying such a heat wave would have been “virtually impossible” 50 years ago. It was a high-profile claim from a field called extreme event attribution, which seeks to gauge how global warming impacted a particular heat wave, flood, or storm. The field is still evolving, according to a report released today by the National Academies of Sciences, Engineering, and Medicine (NASEM). ...In the past decade, attribution science has advanced rapidly , with the annual number of studies more than doubling since 2012, according to the report. Better climate models, longer observational records, and more sophisticated statistical techniques have all improved researchers’ abiliti...

As the Arctic warms, gray whale boom turns into a bust

By -
By Warren Cornwall , Science.  Excerpt: Whale CRC-2293 was once part of a celebrated revival, a member of a burgeoning population of gray whales ( Eschrichtius robustus ) in the eastern Pacific Ocean. The population, once depleted by commercial hunting to just a few thousand animals, had flourished following the 1980 moratorium on most whale hunts, to the point that it was deemed to no longer need protection under the U.S. Endangered Species Act. ...Since 2019, gray whales have been washing ashore in unusually high numbers as they migrate from Mexico, where they overwinter and give birth, some 8000 kilometers to their Arctic feeding grounds. The death toll slowed for several years. But in the past 2 years it has surged again toward record levels up and down the North American coast while overall populations have fallen to less than half their peak. Scientists are now predicting a sustained decline. The likely cause: ...“a fundamental regime shift in their feeding grounds in the Arc...

In Gambia, Salt Water Intrusion Is the Leading Edge of Climate Change

By -
By Phred Dvorak , Inside Climate News.  Excerpt: The little nation of Gambia is on the front lines of a global struggle with salt, as a combination of climate change and human activities push ocean waters further inland, threatening ecosystems, aquifers and agriculture.  Most of the salt intrusion is taking place along coastlines and deltas, where rising sea levels send saline water flooding ashore, seeping underground and changing the chemistry of nearby land. Droughts increase salinity too, since there is less rainfall to dilute the salt or flush it out. Both phenomena are expected to worsen with global warming. ...In farming areas, the overuse of fertilizer can increase salt levels in soil as well....  Full article at https://insideclimatenews.org/news/12072026/gambia-sea-level-rise-agricultural-crisis/ .

Trump taps climate science denier to run US government’s flagship climate report

By -
By Dharna Noor , The Guardian.  Excerpt: The Trump administration has tapped a former geochemist who has railed against “climate alarmism” and calls himself an “Earth science professor-in-exile” to oversee the federal government’s flagship report about climate impacts on the US. Matthew Wielicki, who lacks formal training in climate science, will now lead the nation’s Global Change Research Program, which federal officials have gutted during Trump’s second term. In his new position, Wielicki will lead the National Climate Assessment, a congressionally mandated report detailing how Americans are affected by the climate crisis. ...The assessments are required to be produced every four years under legislation passed by Congress in 1990 , but last year, the Trump administration shut down the online portal to access the five editions published since 2000. Wielicki is a climate science denier who frequently criticizes established climate science online , including in videos by right...

Ocean acidification may be shrinking the brains of the world’s most intelligent invertebrates

By -
By EurekAlert!  Excerpt: An ongoing research project exploring the effects of rising levels of oceanic CO 2 on squid neurology reveals that exposure to future levels of ocean acidification could shrink their brain volume by around 50%. This severe brain shrinkage appears to be most pronounced in the areas that interpret visual information, correlating with significant reductions in normal feeding behaviours and suggesting serious consequences for the future of squid and other cephalopods. ...To investigate the effects of future ocean acidification on the squid neurology, ...Dr Allen and project lead Dr Yung-Che Tseng ...at Academia Sinica’s Marine Research Station reared the squid in one of two parallel water tanks: one representing the modern oceans (pH 8.2) and one representing the oceans in the year 2100 under a predicted climate change scenario (pH 7.8). After 90 days, the squid were removed and their heads were preserved for visual analysis with diffusion magnetic resonance i...

The Ocean Has a 'Fever.' These Are the Symptoms

By -
By Arden Dier , Newser.AI .  Excerpt: The massive marine heat wave, formed as a North Pacific hot spot merged with warming tied to a developing super El Niño along the equator, covers about 13.5% of Earth's surface, stretching from the Philippines to Peru and toward Hawaii and California...the Washington Post reports. Forecasters say the heat is already helping fuel Super Typhoon Bavi in the western Pacific and could help set up a strong heat dome over the western US in mid-July, heightening fire risks from Arizona to Colorado. As the ocean absorbs heat, the water expands, with implications for global sea levels. ...sea levels this winter could run 6 inches to 2 feet above normal—with storms pushing that surge to 2 to 3 feet higher, raising the odds of disruptive coastal flooding, the Post reports. ...Globally, marine heat waves now cover more than 37% of the ocean, triple the share seen in the late 1980s....  Full article at https://www.newser.com/story/392288/pacific-ocean...
