Rising tides could wipe out Pacifica, but residents can’t agree on how to respond

By Connor Letourneau, San Francisco Chronicle. 

Excerpt: “When people fight the ocean,” [Pacifica, City Council member Christine] Boles said, “the ocean always wins.” ...Pacifica, a picturesque surf town of roughly 35,000 just south of San Francisco, has become an important case study for the increasingly urgent questions climate change raises for many coastal communities. Should residents stay to defend their homes from rising tides that grow fiercer by the year? Or, should they admit defeat and cede the land back to nature? ...“Managed retreat” — a term coined by geologists to describe the process of removing people, homes and businesses from at-risk areas — is at the root of the debate. ...“We can’t build seawalls high enough to protect us forever,” said Gary Griggs, a professor of Earth and planetary sciences at UC Santa Cruz. “So, in the long run, it’s either going to be managed retreat or unmanaged retreat. It’s up to each community to decide.”...

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 .

Warmer, more crowded cities bring out the rats

By -
By Elizabeth Pennisi , Science.  Excerpt: Climate change  emerged as a driving factor behind urban rat swarms , the researchers report today in  Science Advances . As temperatures rise, they conclude, and people flock to urban areas and convert formerly “green” spaces into neighborhoods and shopping centers, they created a perfect storm for rat populations to explode. And the city that’s fared the worst over the past decade? Washington, D.C.....  Full article at https://www.science.org/content/article/warmer-more-crowded-cities-bring-out-rats .
