NEW – Factcheck: No, Europe is not having its ‘quietest’ year for wildfires ✍️ @giulianaviglione.bsky.social and @rtmcswee.carbonbrief.org 💬 With comments from @calxcunningham.bsky.social Read here: buff.ly/pDQGTR3

Rahmstorf: “Some people think we can wait and, when it gets too bad, then we reduce emissions People don’t realise that we can’t make it get better again. We can only prevent it from getting much worse.”

In today’s climate, events of this intensity are expected to occur once every 20 years in southwestern France and once every six years in central Spain.

Human-induced climate change made the extreme fire weather that fuelled the recent destructive wildfires at least twice as likely in France and at least 20 times more likely in Spain, according to our new study.

The model spread for this year's El Niño forecasts remains insane. 11 of the 13 models expect a very strong (aka "super") El Niño. (rONI > 2 °C) 7 of 13 expect the strongest El Niño in modern history.

Here's the CCC's @elpinchbeck.bsky.social speaking today in front of the Met Office's new "future forecast" for a... ..."plausible 2056 heatwave". Yes, that's showing 45C (113F) in the Bristol area! With exquisite timing, the UK's all-time June temp record is due to be broken this week.

BREAKING: UK govt is targeting 87% cut in emissions by 2040 under the 7th "carbon budget" It says meeting this target will boost energy security, lower bills, create jobs and growth, improve quality of life – and tackle the "climate crisis"
