I feel like xkcd has been getting more into geoscience the last couple of years, and I absolutely love it. Bonus text reads "the administration thinks it's weird, but the geologists say it looks normal." xkcd.com/3284/
xkcd comic #3284, which shows a building labeled "department of geology," but all of the features of the building are slightly offset along a fault running diagonally through the middle. Caption is "The administration regretted giving the geology department free reign to design their new building."

...And, again today, a huge swath of the continental United States clear across from the Pacific Coast to Mississippi River is experiencing all-time March monthly record heat. Some locations are so hot that they are actually exceeding *April* all-time record highs. Incredible.
Map of U.S., from coolwx.com, showing locations currently experiencing record-breaking temperatures. There are countless such locations in the Western U.S., with hundreds of red dots (locations breaking daily record highs) and countless pink dots (locations breaking March monthly record highs). The region of record heat extends from the Pacific Coast to the Mississippi River, and from Canada to Mexico. The region of red and pink dots is vastly larger even than yesterday's.

The official NOAA stats out this week confirm that winter 2025-26 was the warmest on record across a huge portion of the western and central U.S., which has contributed to extremely low mountain snowpack & worsened the CO River crisis. Meanwhile, record March heat is in forecast.
Official map from NOAA depicting the relative rank of winter 2025-2026 temperatures at a county level across the contiguous U.S. Many counties in the western and central U.S. are depicted in dark red color, signifying record-warmest winter. All other counties in the west and central U.S. are depicted in dark orange colors, signifying a "near record warm" rank.

We used an isotope-enabled climate model and process of elimination to determine that the negative excursions in dDwax are likely driven by a combination of more humid conditions and an earlier start of the growing season during warm interstadial phases.
