As the first reanalysis data become available, I think I can say with a fairly high degree of confidence that the March 2026 heatwave will go down as the most anomalously extreme heat event ever observed at any time of year in the southwestern U.S.

The last 11 years have been the hottest years ever recorded. Earth’s energy imbalance has reached its highest than at any time in observed history, with heat reaching deeper into the ocean. This is the Global #StateOfClimate 2025. 📰 Press release: https://bit.ly/4ds4r2V #WorldMetDay

This Saturday marks #WorldGlaciersDay. Understanding how glaciers and ice sheets move, thin, and lose mass is essential for projecting sea level rise. @esa.int Climate Change Initiative Glaciers and Ice Sheets projects deliver the satellite data to do just that. Find the projects here: t1p.de/5gm62

Thwaites Glacier could lose as much ice in 40 years as all of Antarctica does today. A new study shows that using satellite altimetry to calibrate ice-sheet models makes predictions up to ten times more accurate - increasing confidence in future sea-level projections.

2️⃣ While the study in @pnas.org shows most of the coastline remains stable (for now), in three decades the ice sheet has retreated from the grounding line (where continental ice meets the ocean) at an average rate of 442 sqkm per year, mostly in West Antarctica. ▶️ www.pnas.org/doi/10.1073/...

The intense upwelling of the last few weeks has collapsed as trade winds failed again. One possible reason is the Bermuda high is weak and positioned east than is needed to drive the pressure gradient that sets up wind-jet upwelling in the Gulf of Panama, although this idea needs further exploration

In a sane world, this would be front page news everywhere. But it will hardly be covered anywhere. The North Pacific Ocean surface warmed over twice as much over the past 15 years than it did over the preceding 156 years. That's an increase in warming rate of >2000%!

Breathing in air pollution from wood burning increases your risk of heart and lung disease, asthma, diabetes and dementia. Even homes with newer “Ecodesign” wood burners are three times more polluted than those without. This #CleanAirNight, share the facts about wood burning.

Shanghai famously turned its back on the bike decades ago, surrendering its streets to cars in pursuit of economic prosperity. But in the coming years, they will make a remarkable U-turn, reclaiming substantial road space to add 1,250 km of high-quality cycling routes in the name of urban vitality.🧵
