Sea ice extent in the Bering as been basically flat the past week and is now decidedly below the 1991-2020 median. Storminess early this week will likely result in some retreat of the ice edge but then a shift to north winds later in the week would allow for some expansion. #akwx #Arctic #SeaIce

Sea ice extent in the Bering as been basically flat the past week and is now decidedly below the 1991-2020 median for this point in the season. Storminess early this coming week will likely result in some retreat of the ice edge but then a shift to colder northerly winds later in the week would allow for some expansion. @ZLabe @Climatologist49

Hey #seaice researchers. Please stop citing my 2008 paper as evidence that sea ice floe size distributions follow power laws!!!

Yes I wrote that we found a power law *for the data at the time* then criticized it because it was so limited.

This is mentioned in the discussion. And the appendix.

So, citing it without the critique, I know you didn't actually read it.

I gave Agnieszka Herman my data and I'm pretty sure it contributed to this: https://journals.aps.org/pre/abstract/10.1103/PhysRevE.81.066123

Hey, it's that time of year for my seasonal poem A Christmas Peril. When I originally wrote this, in 2008, it seemed to many people that it expressed a distant possibility, but was a cute fairy tale.

Even then, also in 2008, I had done some back of the envelope calculations that suggested to me the possibility that human civilization could be wiped out, perhaps even humanity could go extinct, as early as 2035. But I didn't expect any one would believe it.

Now, less than twenty years later, I feel almost embarrassed circulating it because I hope most people can easily see how it pales against the stark and aggressive reality that the Climate Crisis is.

As for 2035? Well, I hope we have at least that long, but I'm a little worried we don't. Acceleration is a weird thing. Civilization may seem solid, but there are things that could happen (crop failures are the one I'm looking to) that could cause everything to unravel really quickly.

Maybe I should be updating my poem. But, for now, this is what I have to offer. Please read it if you haven't, and share it with family and friends as part of your holiday season. Mastodon boosts count as part of that, if you're of a mind to. :)

Happy holidays, everyone. The Climate Crisis isn't a very happy thought, but it underscores the importance of savoring civilization, stability, family, and friends while you can. I'd like to be wrong. But I wouldn't bet money on it.

The poem is available in three languages (English, Spanish, and Portuguese) with several audio tracks.

The Arctic Just Experienced Its Warmest Year on Record

Sea ice extent in the Bering Sea slightly above the 1991-2020 median for mid-December in NSIDC data. Storminess late last week wiped out most of the ice near the Russian coast southwest of Cape Navarin and opened up the area between St. Lawrence Island and the Bering Strait. #akwx #Arctic #SeaIce

In November 2025, the #SeaIce global extent was 8.7% below 1991-2020 mean. Since the beginning of records (1978):
- #Arctic, 2nd lowest monthly mean, with 11.7% less extent than normal (-1,198,440km²)
- #Antarctic, 4th lowest monthly mean, with 7.3% less extent than normal (-1,188,737 km²)

Fascinating film about a Finnish couple over-wintering in a yacht in a remote corner of Greenland... 😍

The Chukchi Sea is now iced-over and attention turns to the Bering Sea. Recent cold and windy weather has driven a rapid increase in sea ice extent in NSIDC data. Total extent is the highest for Dec 6 since 2021. Upcoming weather pattern change will slow ice extent increase. #akwx #Arctic #SeaIce

The Chukchi Sea is now iced-over and we turn our attention to the northern Bering Sea. Recent cold and windy weather has driven a rapid increase in sea ice extent in NSIDC data. Total extent is the highest for this point in the season since 2021 and a bit above the 1991-2020 median. Change in the weather pattern coming this week with more south winds, slowing ice extent increase. @Climatologist49 @ZLabe

That feeling when the sea you know and love becomes locked in white...and it feels like that's how it will be, from now on. With even the gods themselves falling into silence...

Ice-over of the Chukchi Sea (northwest of Alaska) on December 3 as open water area dropped to under 5 percent of the basin in NSIDC data. Similar timing to last year but earlier than most autumns 2013-2023. Of course, still later than most years before 2002. #akwx #Arctic #SeaIce

Whorls of Sea Ice

Fresh snow shines white on the southern end of Greenland in this satellite image, taken in late February 2025. Whorls of sea ice sit off the coast, where they trace out patterns that reflect the winds and ocean currents of the region. Arctic sea ice typically reaches its largest extent by early March before experiencing a long season of melting. Both the presence and absence of sea ice have a large effect on the Arctic regions. Sea ice helps dampen wave activity; without it, seas are higher and more dynamic, creating more aerosols that seed cloud cover in the Arctic and elsewhere. (Image credit: L.

Update on where Arctic sea ice is at as of the end of November is now posted in at the Alaska and Arctic Climate newsletter. Spoiler: it's not good, not good at all. #akwx #Arctic #SeaIce #Climate #Canada alaskaclimate.substack.com/p/november-2...
