(Climate) "Coverage is punctuated by bursts of attention to late-year international climate conferences, but the recent decline persists even when you smooth that out. And it appears poised to continue. The real question is how far coverage can fall."

Impossible to quantify how much this has already hurt the next generation of scientists.
This a word cloud from the titles of ~1100 terminated NSF grants.

It is hard not to see these grant terminations as an attack on the training of the future United States scientific workforce.

Carbon dioxide (CO₂) averaged about 429 ppm in January 2026

10 years ago January averaged about 403 ppm

Last month observed unusually high sea surface temperatures in areas near a lack of sea ice, such as the Labrador Sea and western Bering Sea. Ocean temperatures continued to be very warm north of Scandinavia as well.

"How and how much the media cover climate change matters greatly.

This 2025 downward trend appears in contrast with ongoing global warming where average temperatures in the most recent years have been the highest in nearly 150 years of recorded history."

January 2026 #Arctic sea ice extent was statistically tied (with last year) for the 2nd lowest on record for the month...

This was 1,310,000 km² below the 1981-2010 average. January ice extent is decreasing at about 2.85% per decade. Data: @nsidc.bsky.social (nsidc.org/data/seaice_...)

It is currently austral summer, which means that #Antarctic sea-ice extent is on its way to the annual minimum. This year will *not* be a new record low, partially due to very widespread ice cover in the Weddell Sea.

This is the point I keep trying to get across in media interviews and conversations.

The science and data matter (obviously), but this is fundamentally a *people* story. These losses and lack of opportunities affect real people, real communities, and the impacts will last for decades.
The state of the field is bad, actually.

The private sector seems to be still doing ok but the rest is hanging by a thread.

We have government shutdowns roughly every 2 months. Federal workers are treated like 3rd class citizens. NCAR as we know it may very well cease to exist.

Last month was the 13th lowest #Antarctic sea ice extent on record for the month of January.

Monday ice update - #Arctic sea ice extent is currently the 3rd lowest on record (JAXA data)...

• about 910,000 km² below the 2000s mean
• about 1,480,000 km² below the 1990s mean

Large departures in #Arctic sea ice continue around Baffin Bay and the Labrador Sea, as well as the Barents Sea and Sea of Okhotsk. Resulting from the recent weather pattern, Bering Sea ice has a sharp locational gradient.
