Putting the Arctic sea ice record straight

For the third month running low pressure was dominant over the Central Arctic Basin during August: greatwhitecon.info/2026/09/fact... Temperatures at the 925 hPa pressure level were anomalously high across most of the Arctic, particularly over the Kara Sea and Canadian Arctic Archipelago.

Here's a “false colour” image of the swirl of cloud caused by a cyclone over the central #Arctic this morning. The choice of frequencies in the visualisation makes it easier to distinguish clouds from snow and ice. More at: greatwhitecon.info/2026/06/fact...

In other news from the High North, it now seems exceedingly unlikely that JAXA extent will achieve a record low maximum this year. The metric is currently 4th lowest for the date (in the satellite era) at 13.68 million km², marginally below last year’s maximum of 13.78 million km². 2/2

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again. www.nature.com/immersive/d4...
This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.
