Specifically, we devise a combined reanalysis/model estimate of the likelihood of current records being broken, in which the eastern US, eastern China, & Australia stand out. We also find MENA and the tropics endure the most severe, long-lasting, and clustered events, and the greatest uncertainties.

Alarmingly, the single largest ERA5 daily wet-bulb temp affects estimated return periods by a factor of >3 or even >10 in many regions, including those where JRA55 and NOAA20CR agree well. We address this undersampling of possibilities by bringing in large ensembles...

The year 2025 and this podcast's title have partly converged, but other social, technological, etc. trends also feature prominently. As always, the new season contemplates topics that feel fresh and necessary, aiming to come to some fuller understanding. At the least, this helps preserve sanity.

Multiple model ensembles are already suggesting a broad region of record mid-tropospheric ridging over the far NE Pacific and Washington/British Columbia, with possible record-breaking late-season warmth in the same region. That's a very strong signal ~1 week out. #WAwx #ORwx #BCwx

2024 was another boom year for humid heat, esp. in East/South Asia. Hats off to Kate Willett and all for packing much info and definitional complexity into the kind of thing one could read over breakfast -- if one likes to start the day with multi-panel figures and intricately abbreviated variables.
