A patch of the North Atlantic is cooling while the world warms — a symptom that the ocean current carrying tropical heat north is slowing. New 2026 work says it's happening sooner than the models expected, and that the door, once crossed, does not reopen.
El Niño is no longer forming — it has formed, and the forecasts now point past "strong" toward the rare "super" tier, with a real chance of the strongest on record. What a very strong El Niño would mean for the year ahead — and why the honest answer is still a tilt in the odds, not a certainty.
El Niño has not just formed — it is firming toward the top of the record. The latest forecasts now put every major model at strong or above, with most reaching "super" territory. What that means for the year ahead.
A glacier on the Antarctic Peninsula collapsed faster than any modern observation has recorded. Scientists now know the mechanism. Whether the climate models that predict the future of the West Antarctic Ice Sheet account for it is a different question.
The Planet section of this edition reports the structural picture: Amazon deforestation in Brazil is on pace for its lowest year on record, driven significantly by the expansion of legally
Near-real-time satellite alerts indicate that Amazon deforestation in Brazil is on pace, for the period August 2025 through January 2026, for the lowest cumulative clearing in that window
The World Meteorological Organization's State of the Climate in the South-West Pacific 2026 report, released earlier this year, contains the data that anchors much of the Pacific
For most of the satellite record, Antarctic sea ice behaved differently from its northern counterpart. While Arctic sea ice declined steadily from the late 1970s onward — eventually losing roughly half
On 20 May, the United Nations General Assembly adopted resolution A/80/L.65, which formally endorses the International Court of Justice's July 2025 advisory opinion on the
A paper published this week by researchers at the University of Edinburgh, in the journal Communications Earth & Environment, concludes that the Arctic Ocean has undergone a regime shift driven
