Explainer: How the ‘super El Niño’ will reshape the world’s weather
The world is currently experiencing what is expected to become the strongest El Niño on record – dubbed a “super El Niño” by many.

The ongoing EU heat wave is undoubtedly already historic. The extent of Saturdays convective activity determines Germany's fate on Sunday. Everything from mind-boggling 43°C to just above 40°C is up for grabs. Extremely dangerous, but synoptically tantalizing 🔥 kachelmannwetter.com/de/modellkar...
Four panels with coloured temperature values for Germany (Sunday). Red for moderate maxima and white for extreme maxima. Eastern Germany mostly white, all else more reddish.

#ClimateChange impacts “can force people to stay in place” resulting in involuntary immobility due to various obstacles, e.g., political & social. As @lisathalheimer.bsky.social et al. note, a lack of data & knowledge inhibits policy & planning to address this growing problem doi.org/10.1038/s414...

Confusing title - it sends a *wrong* signal that people can migrate under future warming. Heat and other extremes force people to stay in disaster areas. We discuss some of these involuntary immobility challenges in our upcoming publication. Stay tuned.

2024 is almost history and the global temperature forecast for the remaining few days is rock solid now. Time to wrap up. In most datasets, 2024 will be 0.1 degree C warmer than 2023. Also, 2024 will be the 1st individual year above the 1.5 degree Paris warming threshold in all datasets. (1/10)

Disaster is a function of three things: exposure, vulnerability, and hazard. As climate change pushes up the hazard rates for wildfire, flood, hurricane & more, lack of adaptation and maladaptation on the part of both public and private entities is increasing vulnerability.
