Excerpt: Hawaii shuttered its last remaining coal-fired power station on Thursday, a major milestone in the state’s ambitious effort to transition to 100 percent renewable energy by 2045. The station, the AES Hawaii Power Plant near Kalaeloa, in southwest Oahu, provided more than 11 percent of the state’s electricity in 2021, according to data from the U.S. Energy Information Administration. “It really is about reducing greenhouse gases,” said Gov. David Ige, a Democrat, in an interview with The Associated Press. “And this coal facility is one of the largest emitters. Taking it offline means that we’ll stop the 1.5 million metric tons of greenhouse gases that were emitted annually.” Throughout the United States, coal plants are powering down, squeezed out by cheaper natural gas, cleaner renewable energy and tougher emissions regulations. There are fewer than 270 coal-burning power plants remaining in the country; more than 600 have been retired over the past two decades.…

Like McCann, the three others had turned up feverish and confused. ...among the possible causes were mosquito-borne viruses, in particular two encephalitis-causing viruses endemic to Australia: Kunjin, a strain of West Nile virus, and Murray Valley encephalitis virus (MVEV), named for the river valley where McCann has swum, water skied, fished, and boated since he was a boy. ...As with other weather events, the record-breaking wetness of the 2021–22 season can’t be attributed with certainty to climate change. But as the globe warms, the atmosphere holds more water, enabling more intense rainfall and flooding; daily rainfall associated with th

Relax, Electric Vehicles Really Are the Best Choice for the Climate

Those conditions need to be addressed, but it’s a mistake to view them in isolation. Oil extraction h

Lost history of Antarctica revealed in octopus DNA

https://www.science.org/content/article/lost-history-antarctica-revealed-octopus-dna By ERIK STOKSTAD .  Excerpt: Some 100,000 years ago, scientists believe Antarctica’s massive western ice sheet collapsed, temporarily opening waterways between a trio of seas surrounding the continent. New evidence for that scenario comes from a surprising source: octopus DNA. ...About 129,000 to 116,000 years ago, a warm spell called the last interglacial gave our planet a brief break in between several million years of ice ages. The average temperature of the planet was about 0.5°C warmer than it is today—and climate projections predict it will be again within decades. The global sea level was also 5 meters to 10 meters higher than current levels. Many scientists believe  the collapse of the West Antarctic Ice Sheet and consequent melting could have been a primary reason . ...The findings are consistent with growing geological evidence supporting the ice sheet collapse....
