Excerpt: Record-breaking warm waters have bleached large parts of Australia’s Great Barrier Reef this year, as they did in 2016 and 2017, scientists reported on Thursday — the latest sign that global warming threatens the health of one of the world’s most important marine ecosystems. “We can confirm that the Great Barrier Reef is experiencing its third mass bleaching event in five years,” David Wachenfeld, chief scientist of the Great Barrier Reef Marine Park Authority, said in a video [http://www.gbrmpa.gov.au/the-reef/reef-health] posted on its website. ...Scientists say reefs around the world have been dying at an alarming rate for several years because of global warming. Reef corals grow very slowly, and while most of them can live only in warm water, they are highly sensitive to above-normal temperatures....

2024 was the hottest year on record, breaching a critical climate goal and capping 10 years of unprecedented heat

By Laura Paddison , CNN.  Excerpt: It’s official: 2024 was the hottest year on record, breaking the  previous record  set in 2023 and pushing the world over a critical climate threshold, according to new data from Europe’s climate monitoring agency Copernicus [ https://climate.copernicus.eu/copernicus-2024-first-year-exceed-15degc-above-pre-industrial-level ]. Last year was 1.6 degrees hotter than the period before humans began burning large amounts of fossil fuels, Copernicus found. It makes 2024 the first calendar year to breach  the 1.5-degree limit  countries agreed to avoid under the Paris climate agreement in 2015. Scientists are much more concerned about breaches over decades, rather than single years — as above that threshold humans and ecosystems may struggle to adapt — but 2024’s   record   “does mean we’re getting dangerously close,” said Joeri Rogelj, a climate professor at Imperial College London....  Full article at https://www.cnn.c...

Where Glaciers Melt, the Rivers Run Red

By Mitra Taj , The New York Times.  Excerpt: As the glaciers of South America retreat, the supply of freshwater is dwindling and its quality is getting worse. Dionisia Moreno, a 70-year-old Indigenous farmer, still remembers when Shallap River, nearly 13,000 feet up in the Cordillera Blanca, brought crystal clear water brimming with trout to her village, Jancu. “People and animals alike could drink the water without suffering,” she said. “Now the water is red. No one can drink it.”....  Full article at https://www.nytimes.com/2024/11/19/science/peru-glaciers-water-pollution.html .

How will China impact the future of climate change? You might be surprised

By -
By Julia Simon , NPR.  Excerpt: The U.S. is preparing for a second presidential term for Donald Trump, who has called climate change a hoax and federal investments in climate solutions a " green new scam “. In China, it’s a different story. China has made it clear it plans to be at the forefront of manufacturing climate solutions–and selling them around the globe. China is the world’s largest producer of renewable energy, now constructing almost  two thirds of all large-scale wind and solar power , according to nonprofit Global Energy Monitor. And China is spreading climate solution technologies across the developing world. Walk into an electric vehicle showroom in Colombia, the Dominican Republic, or Kenya these days, and the car on offer is likely made in China. “They’ve set up a situation where it’s good for them to sell clean energy technologies to the world,” says  Alex Wang , a professor of law at UCLA focused on Chinese climate policy. “It’s very good economically,...
