Record‑strong El Niño forecast fuels climate alarm and Swedish policy calls

Climate researcher Zeke Hausfather says analysis of the latest climate‑model ensemble indicates the El Niño developing this year is likely to be the strongest since reliable measurements began, with a median sea‑surface‑temperature anomaly of about 3.6 °C – roughly 0.8 °C higher than the previous record set in 2015‑16. He warned, "The models predict something outside the range we have ever observed," noting that the difference between the strongest and the fifth‑strongest events over the past 150 years is only about 0.5 °C.

The World Meteorological Organization’s most recent annual report describes a climate system in unprecedented imbalance: greenhouse‑gas concentrations are at all‑time highs, the past 11 years have been the warmest on record, sea‑level rise is accelerating, glaciers and Arctic/Antarctic ice are melting faster, and extreme weather events are becoming more frequent. The report links rising heat waves to food insecurity, social instability, migration pressures, and heightened health risks.

In Sweden, the Climate Political Council warns that current national policies will miss all climate targets. It urges voters to back parties with strong environmental platforms and highlights Professor Kimberley Nicholas’s SHIFT guide, which stresses collective, structural actions over individual lifestyle changes as the most effective way to mitigate the crisis.
