Distinct and synergistic influences of sea ice rheology and seabed stress on simulated Arctic fast ice

Abstract. Fast ice (FI) refers to sea ice that remains mechanically immobilised along the coast for extended periods. In the Arctic, its presence influences the stability of the halocline by displacin...

The progress we made in moving away from higher emissions futures should tell us that progress is possible. But it shouldn't breed complacency; the risks remain far too high and grow with each molecule of carbon emitted. The world still isn’t nearly concerned enough.

This is what a monster El Niño on an ocean already warmed by climate change looks like.

Jeff Berardelli @weatherprof.bsky.social · last wk.

It’s official, the 2026 El Niño has broken a record for the highest ocean anomaly in 170+ years… Incredibly reaching that threshold a full 2 months ahead of 2015’s record of +3.02C set on Nov 18th. See that red line? That’s 2026. Every other bold line are the strongest El Niño’s on record. 1/

#Europe and #Canada are talking about a closer partnership. @esa.int has been showing what that can look like for decades: Canada has been its only non-European Cooperating State since 1979.

Here is the latest combined forecast across all 14 models, compared to past strong El Nino events. It shows just how extreme and unprecedented this event is forecast to be:

Here is an example of how relentless and excessive the heat has been in parts of Europe. Baden-Württemberg in SW Germany added a whopping 30% of hot days (>30°C) to the previous warmest year. London with 55 days w/o rain is also mad #ClimateEmergency Source: www.mtwetter.de (image modified) (2/2)

Globally, the hottest August in observed history is just about to end. In Western Europe, the summer of 2026 (June, July, August) has been the warmest as well. Compared to this year, 1976 (the famous UK summer) and 2003 (the hottest EU summer so far) look like amateurs in terms of heat (1/2)

A millennium-long record from Galápagos corals suggests that El Niño is intensifying as the planet warms, with ENSO variability in the eastern Pacific roughly 37% higher than during the preindustrial era. Learn more: https://scim.ag/4zJ0DTJ

A comprehensive new study finds that the El Niño events during the past 40 years are 36% stronger than those during the preindustrial era, a trend that is likely tied to climate change. www.cnn.com/2026/08/27/c... [THREAD] 1/
