Thanks @Longreads for picking my Rockhoppers story as one of this week’s Top 5! Love the write-up — you really captured the piece. Team Penguins! 🧪🐧 longreads.com/2026/02/06/t...

Great to see the Olympics finally ban PFAS in ski wax! I first reported on this environmental health hazard in 2011: www.scientificamerican.com/article/ski-... grist.org/culture/the-... 🧪⛷️❄️

I'm thrilled to have the Rockhopper penguins story I reported from the Falklands called out in today's New York Times! No, it's NOT about Trump... it's in the second half of Frank Bruni's column: "For the Love of Sentences." 🧪🐧 www.nytimes.com/2026/02/02/o...

Southern Rockhoppers are the world’s cutest and most badass penguins. I visited their Falkland Islands colonies to report on the problems they now face—and the pluck that may see them through. My story in Smithsonian Magazine, with photos by Chris Linder🧪🐧 www.smithsonianmag.com/science-natu...

Puffins in the Pacific? Yes, Tufted Puffins! They’re every bit as cute as Atlantic Puffins—and largely unknown. My latest, for Audubon Magazine, about scientists looking for causes and solutions to these intrepid mariners’ steep decline. 🧪🐧 www.audubon.org/magazine/tuf...

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...

Kudos to @agu.org and @ametsoc.org for stepping up to fill the National Climate Assessment void! 🧪 news.agu.org/press-releas...

Tariffs on Svalbard and Jan Mayen? Just about the only thing these remote Arctic islands export is science…🧪 www.thebarentsobserver.com/news/trump-s...

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. 🧪🪫💡

Check out the changes in January #Arctic sea ice thickness by decade... Data information: climatedataguide.ucar.edu/climate-data...

Love the headline on this important story about the escalating potential for land grabs in the Arctic: www.thebarentsobserver.com/news/halfwit...

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...

Older people, Democrats and analytical thinkers best able to tell true from fake news, interesting new study shows. www.pnas.org/doi/10.1073/...

The world’s greenhouse gas output continues to soar, new ⁦‪@NOAA‬⁩ report shows. CO2 levels averaged a record 419 ppm last year, while methane topped 1922 ppb.
