This heatwave is yet another climate-driven extreme. Even as fossil fuels spike in price from geopolitical chaos, their indirect costs keep adding up in an ever hotter world through more dangerous weather. They're just not great, to be honest.

A chart showing the seasonal cycle of daily maximum temperatures averaged over a large part of the western US (smoothed over a running 5-day mean). The average seasonal cycle from 1950-1979 (what we used to expect) is shown in blue, and the average from 1996-2025 (what we expect now) is in red. The red line is always above the blue line, and in March is several degrees higher. A black line shows the temperatures recorded this year, which reached more than ten degrees C above what we would expect in March, a level described by scientists as 'what the frickadoodles?'

Mind-boggling out-of-season heat in western North America right now - our new rapid study found it's been made much hotter by climate change. Check out our @wwattribution.bsky.social study, but I also made a handy figure to illustrate the bonkersness.

🚨 NEW STUDY: As Australia prepares for another heatwave, our latest study found the early January heatwave which hit SE Australia was made 5x more likely due to climate change. What was once a relatively rare 1-in-25-year event is now expected about every 5 years. 🧵 1/6

⛈️ Climate change made record-breaking downpours behind deadly Midwest and South US flooding 9% more intense.
