More evidence a cold spell helped doom the Roman Empire

Excerpt: Historians have long debated the reasons why the Roman Empire—which once stretched across the Mediterranean sea and from northern Africa to the U.K.—collapsed. Recently, some have pointed to a sudden period of cooling called the Late Antique Little Ice Age. This cold spell could have hindered agricultural production, facilitated disease outbreaks, and driven people to migrate. According to a new paper, serendipitously discovered rocks on the shore of Iceland add to the evidence for this chilly period. ...the change in climate may have compounded the troubles of an empire that was already in decline. “When it comes to the fall of the Roman empire, this climate shift may have been the straw that broke the camel’s back,” co-author Tom Gernon told The Independent....

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,...
