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.

According to #ClimateCentral's @kaitlyntrudeau.bsky.social, "Climate change is increasing the risk of critically-dry conditions that set the stage for extreme fire behavior — and that's exactly what we've seen so far in 2026.” 🎥Watch our latest Monthly Climate Briefing: youtu.be/XUtVXGG1UqA?...

The global surface temperature record is one of the most iconic figures in climate science. We now have 12 different groups of researchers from the US, UK, EU, Japan, and China (among others) that have calculated it and found nearly identical results:
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...

In late February, after reopening thousands of refugee claims in Minnesota, the White House said ICE agents would be empowered to detain legal refugees in the U.S. indefinitely for “aggressive rescreening.” trib.al/H9nHeqf

Somali immigrants in the U.S. haven’t just fled violence—they’ve fled climate catastrophes that the U.S. has helped create.

Mongabay@mongabay.com · last yr.The world’s most vulnerable people increasingly face threats related to climate change. Many lack the ability to move away from impacts like heat, flooding and landslides. Experts say governments and organizations can invest in low-cost interventions aimed at reducing suffering.
#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...
Flooded refugee camps. Heat-stricken urban communities. Displacement isn’t always a choice—many people want to leave but can’t. "Leaving isn’t an option, and staying is increasingly dangerous." – @lisathalheimer.bsky.social, IIASA. #scicomm #climatechange #refugees
‘Trapped populations’ need help to escape climate risks
For many refugees and other populations trapped by poverty and conflict, migration is not an option. So how can they be helped?

As climate risks intensify, many communities are forced to relocate, but what about those who can’t move? A new Nature Communications study led by IIASA researcher @lisathalheimer.bsky.social highlights the struggles of populations trapped in high-risk areas 🌊🌪️🌩️ 👉 iiasa.ac.at/news/mar-202...

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.
