Sunday ice update - #Arctic sea ice extent is currently the lowest on record (JAXA data) • about 740,000 km² below the 2010s mean • about 1,340,000 km² below the 2000s mean • about 1,720,000 km² below the 1990s mean • about 2,260,000 km² below the 1980s mean Plots: zacklabe.com/arctic-sea-i... 🌊

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between January and April by looking at the decadal average line positions.

Just another typical late winter season in the Pyrocene -- "Wildfires rage across the Carolinas...More than 175 wildfires burning across SC and additional fires in NC... Much of eastern US seaboard under increased fire risk." www.yahoo.com/news/wildfir...

Wildfires rage across the Carolinas; SC governor issues state of emergency

The National Weather Service issued advisories on Sunday from Georgia to New Jersey warning of an increased risk of wildfires.

Sometimes it is only one side of the #Arctic that experiences anomalously low conditions during winter, but this year we are seeing the sea ice edge on *both* the Atlantic & Pacific sectors at very low levels for this time of year. This is contributing to the historic record low for early February.

NSF PRFB POSTDOCS: Pull the remainder of this funding cycle’s stipend, all remaining research funds, and all remaining travel funds (if you have them). Do it before 5PM today. Per instructions from multiple NSF POs. If you’re not already on the PRFB slack, DM me and I’ll send you an invite

For my first scientific post here, I want to talk about the Phanerozoic temperature record we published last Fall, which unfortunately has been making rounds in the climate denier circuit 👀 First though hopefully you can appreciate the beauty of this reconstruction ✨...
