Interesting new study finds polar bears aging faster due to stress caused by #ClimateChange. Age advancing by a year for each degree of #Arctic warming—which is now up to +3 C. (Note: report in preprint) www.biorxiv.org/content/10.1... 🧪❄️

Last summer’s record heat wave sent 1% of Svalbard’s ice down the drain.(Well not exactly, but you known what I mean…)❄️🧪 www.highnorthnews.com/en/svalbard-...

Winter temps in Svalbard above freezing for half of Feb.; new @nature.com paper shows the impacts. “When winter warming crosses the 0 °C threshold, it marks more than just a warm anomaly — it signals a fundamental shift in Arctic winter dynamics.” 🧪❄️ www.nature.com/articles/s41...

Arctic sea ice has shrunk to a new record low this year @nsidc.bsky.social reports. Meanwhile, Arctic winter temps have been running up to 2 C above average. 🧪

1000s of Greenland lakes have abruptly shifted from carbon sinks to sources — driving CO2 output up 350%, new @umaine.bsky.social paper in @pnas.org finds. I accompanied the researchers in 2023 and wrote this report from the field: e360.yale.edu/features/gre... 🧪 www.pnas.org/doi/10.1073/...

Well hell — our home solar installation just finished yesterday, at the same time as this:

The massive Moss Landing energy storage facility was largely destroyed by a battery fire this weekend — the 4th (including one at an adjacent site) since I wrote about the project in 2020: e360.yale.edu/features/in-... Could deal a major blow to grid renewable energy storage efforts. 🧪🪫💡

Just got back from the other end of the world to find LA burning, and now this: 2024 was the hottest year on record, new NASA report confirms www.nasa.gov/news-release..., with avg global temp up more than 1.5 C since pre-industrial times, according to @copernicusecmwf.bsky.social 🧪🌡️🔥

Circling back to the tundra, increasing #Arctic wildfires are spewing huge atmosphere-warming emissions. Across the polar region, fires have released on average 207 million tons of carbon per year since 2003, latest #ArcticReportCard shows. www.climate.gov/news-feature... 🧪

Somewhat good news for the Greenland Ice Sheet — this year’s ice loss was the lowest since 2013. Still, the ice sheet shrank by some 55 gigatons, the 2024 #ArcticReportCard says. The best analogy I can find for that is 550,000 fully loaded aircraft carriers.🧪 arctic.noaa.gov/report-card/...

#Arctic temps continue to rise. The 2023-24 annual average was the 2nd highest since 1900. Arctic now warming 3 times faster than the global average, 2024 #ArcticReportCard says. 🧪 arctic.noaa.gov/report-card/...

Summer sea ice remains low, although rate of decline has moderated in the past few years, 2024 #ArcticReportcard shows. This September was the 6th lowest on record. arctic.noaa.gov/report-card/...

The summer of 2024 was the Arctic’s wettest on record, the latest #ArcticReportCard states. Arctic precip predicted to grow as temps rise; falling as rain instead of snow in many parts. arctic.noaa.gov/report-card/...

Warmer, wetter Arctic conditions are turning the tundra from a carbon sink to source, NOAA’s 2024 #ArcticReportCard reports today. Here’s a ground-level view in my story from Greenland: thttps://e360.yale.edu/features/greenland-lakes-climate-change 🧪

A huge congratulations to @thebarentsobserver.com, including my favorite persona non grata @thomasnilsen.bsky.social, for winning the Sønsteby Award! You are a beacon in the Arctic darkness; long may you shine!

How the #Greenland Ice Sheet fared in 2024. SPOILER: It lost about eighty billion (80,000,000,000) metric tons of ice to the global oceans. Or to put it another way: on average, an ice mass of this size every five days.

The Society of Environmental Journalists urges the U.S. Senate to pass S. 2074, the bipartisan #PRESSAct, in the current Congress. It is urgently needed and long overdue. www.sej.org/sej-calls-pa...
