The world has warmed 1.4 degrees since pre-industrial times. Warming has been faster over land, and particularly fast over Europe.
All of which are fuelling UK temperatures in May of 34+ degrees, numbers that were unthinkable when I was born

A pleasure to host @timwoollings.bsky.social, Ken Mylne, @hcbloomfield19.bsky.social & @drchriswhite.bsky.social yesterday for the annual @earthscista.bsky.social symposium, this year on "From dynamics to impacts: Weather in a warming world". Thank you all for visiting and giving such great talks!
The forecast for Sunday in London is 32°C.
There is a chance of breaking the UK record temperature for May of 32.8°C, which occurred back in 1944, just before D-Day.

A big congrats to Josh Duffield, supervised by @drmichaelbyrne.bsky.social, for passing his PhD viva today with @ruthgeen.bsky.social and me as examiners. Some fascinating work on extreme temperatures that was a pleasure to read and discuss! 🥳 @earthscista.bsky.social
Kew Gardens recording 35.1ºC today breaks its previous May record in 1922 before this spell by NEARLY 5ºC and breaks its June maximum temperature record set in 1976 by 0.5ºC - this also beats the previous May UK maximum record by OVER 2ºC (32.8ºC, 1922/44). An incredible anomaly
🌞👨🔬 “It’s not what we’re meant to have in terms of our climate. It’s not what we’re built for...we need to be careful of those kinds of things. These are serious events, and having more of these is not good for us."
- UCD Professor Andrew Parnell, UCD School of Mathematics and Statistics
Today has been the hottest day in May on record with Kew Gardens provisionally reaching 34.8°C - exceeding the previous highest May temperature in the UK by a full 2 degrees Celsius🌡️
This heat would be exceptional in the UK even in mid summer, let alone in May📈
Looks like the UK heatwave will be killed by thunderstorms. Emerging research, from our group and others, suggests the threshold for triggering convection (i.e., thunderstorms) may increase in a warming climate, potentially enabling very hot days to warm more rapidly.
To underscore this even even further, the June record – set during the 1976 heatwave – is only 0.5°C higher but was set over a month later (28 June).
It is staggering to think what is now possible in June, in the current climate (let alone the future), following this record-shattering May heatwave
Rainfall intensity matters as much as how much rain falls.
New in Nature: Corey Lesk and I show that daily-scale concentration of precipitation dries the land over the long-run, an effect as strong as total precipitation is climatological wetting.

The prospect of comfortably beating the current record (32.8C) is "bonkers", according to BBC Weather's Simon King.
Today is now the hottest day in May on record for both England and Wales with Kew Gardens provisionally reaching 35.1°C and Cardiff Bute Park reaching 32.9°C 🌡️
