2025 State of the Climate Report: Our Planet’s Vital Signs are Crashing

By -
By Grace van Deelen, Eos/AGU. 

Excerpt: A yearly analysis of climate change’s progress and effects shows a “planet on the brink” of ecological breakdown and widespread crisis and suggests that only rapid climate mitigation can avoid the worst consequences. ...The sixth annual report, published in BioScience, analyzes global data on Earth’s atmosphere, oceans, energy, ecosystems, food systems, and more. Researchers identified our planet’s so-called vital signs, including ocean temperature, surface temperature, sea ice extent, and carbon pollution. Of the 34 vital signs, 22 were at record levels, indicating a highly stressed Earth system. For example, 2024 surpassed 2023 as the hottest year on record. Ocean heat and wildfire-related tree cover loss are both at all-time highs. Deadly weather disasters surged in 2024 and 2025, with floods, wildfires, and typhoons killing hundreds in the U.S. alone. Atmospheric warming is showing signs of accelerating. Ice at the poles continues to melt, contributing to sea level rise. And the Atlantic Meridional Overturning Circulation, a global network of currents critical for circulating heat on Earth, is showing signs of weakening, which could trigger further climate disruptions....

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 -
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 .
