One novelty of this work is bridging observations and resilience-potential theory. Figure 3 shows how the potential landscape changes under increasing forcing. Special thanks to Prof. Lu Zhou for leading the observation-theory bridge. #Resilience #ArcticSeaIce
As external forcing increases, the ice-covered state loses stability through a saddle-node bifurcation. Reversing the transition requires much stronger cooling, revealing the irreversibility associated with hysteresis. #ClimateScience #NonlinearDynamics
Can resilience be observed? We present a resilience-potential framework that bridges Arctic sea ice observations and nonlinear tipping theory. #Arctic #SeaIce #TippingPoints
We’re launching the 2026 International Summer School on Complex Systems in Earth System 🌍 Explore resilience, tipping points, and climate dynamics through lectures, discussions, and hands-on work. 📍 Tsinghua University 📅 Aug 3–15, 2026 Deadline: June 15
“NCAR has played a greater role in advancing weather prediction & atmospheric modeling than perhaps any other single entity in the world,” says @weatherwest.bsky.social Dismantling NCAR would be “like taking a sledgehammer to the keystone holding up our scientific understanding of the planet.” KH
Trump administration plans to break up largest federal climate research center
Russ Vought, director of the White House Office of Management and Budget, said the National Science Foundation "will be breaking up" the National Center for Atmospheric Research in Colorado.

The Trump regime wants to dismantle a world leading climate research center. Why? Because the US has become a petrostate where the government has been captured by fossil fuel interests. They’re calling climate science “green new scam research”, in full denial of reality. 🤯
USA TODAY@usatoday.com · 8mo agoExclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.
