Last month saw a very large temperature anomaly gradient between the Weddell Sea region and West #Antarctica. In fact, this was one of the very few places anywhere on the globe with colder than average temperatures in August, especially compared to older baselines (e.g., 1951-1980). Data from ERA5.
Polar stereographic map of 2-m air temperature anomalies in the Antarctic for August 2026. Red shading is shown for warmer anomalies, and blue shading is shown for colder anomalies. There is a lot of variability in the pattern of temperature anomalies across the continent. Anomalies are calculated relative to a 1981-2010 baseline.

If you haven't been masking, give it a try. What do you have to lose? Just wear one in crowds and on planes, trains, and buses. Find a style that fits, so you don't futz with it. You don't have to get sick all the time.

High temperatures and low precipitation in the American West last winter led to record-low snowpack. A study finds that such a snow drought is 4.4 times more likely in the current climate than it would have been in the pre-industrial climate. In PNAS: ow.ly/LKKh50ZtquX
Low snowpack is visible on the Front Range mountains from Interstate 25 near Colorado Springs on February 21, 2026, during an unusually dry winter season. Stock photo.

A possibly worthwhile point of clarification: the 'models' discussed here are statistical fits to the last ~100 years of data (from NOAA Atlas 14). This is inevitably backwards looking and will be an underestimate of current probabilities of rainfall intensity in a changing climate.

Of all of the post-splashdown photos from the Artemis II mission, this is my favorite. It captures the best of who we are, the best of who we can be. (More here: www.nasa.gov/gallery/arte...)
NASA astronaut Victor Glover, Artemis II pilot, left, and NASA astronaut Christina Koch, Artemis II mission specialist are seen sitting on a Navy MH-60 Seahawk from Helicopter Sea Combat Squadron (HSC) 23 on the flight deck of USS John P. Murtha after they and fellow crewmates CSA (Canadian Space Agency) astronaut Jeremy Hansen, Artemis II mission specialist, and NASA astronaut Reid Wiseman, Artemis II commander, were extracted from their Orion spacecraft after splashdown, Friday, April 10, 2026, in the Pacific Ocean off the coast of California. NASA’s Artemis II mission took the quartet on a nearly 10-day journey around the Moon and back to Earth. Following a splashdown at 5:07 p.m. PDT (8:07 p.m. EDT), NASA, U.S. Navy, and U.S. Air Force teams are working to bring the Orion spacecraft aboard the recovery ship.
