I’m unconvinced (and @ccallahan45.bsky.social’s has analysis that supports this) this can’t be explained by the rate of greenhouse gas emissions. But anyways, striking article in the same issue in which the editorial board supports EPA’s repeal of the funding that GHGs endanger health and welfare

We don't know what's happening, but there's no good news here. As long as we keep burning fossil fuels, the world will continue to become more dangerous and chaotic.

Ignoring necessity doesn’t preserve choice. It shifts decisions from deliberation to emergency.

Wonderful talk. The best of the maybe 10 I saw over the years. Some slides are made for beginners. Emotion and ethics r pointed out. Attention pulled to experts in lying, eg 🇨🇦Carney and the now-IPCC chair Skea. And calls for self-empowerment: push for progress within your radius so it can spread🕸️💪

The combined direct economic toll from the recent clustering of strong windstorms in Portugal and Spain now tops €8bn ($9.5bn). This total will increase as this primarily accounts for wind and flood damage to agriculture and infrastructure. Storm Kristin Storm Leonardo (Stephie) Storm Marta

Nature's 'engine is grinding to a halt' as climate change gains pace, says study phys.org/news/2026-02...

Necessity reflects timing, not motivation. Late action narrows freedom regardless of intent.

In the past year we've had a series of papers with results that've shocked #climate scientists - the globe is heating #FasterThanExpected & we don't fully know why The public discourse is not keeping up. Here's a series of 5 new studies that climate hawks & journos need to have on their radar 🧵

What once felt optional becomes unavoidable as system limits are reached.

Necessity isn’t ideological. It emerges when delayed choices turn into physical constraints.

“Some are saying we’ll have a 10% GDP loss at between 3C and 4C degrees [of global heating], but the physical climate scientists are saying the economy and society will cease to function as we know" Damn right we are saying this We are in deep, deep, sh*t www.theguardian.com/environment/...

Our new article (doi.org/10.1038/s432...) shows how climate change is reshaping water use and irrigation demand across Central Asia.

I found this history fascinating, especially how the US under Bush I a) pushed to create the IPCC to center government representatives, not scientists, in UN climate action; b) used the IPCC to block binding emission targets and carbon taxes on rich countries, which seemed imminent in 1988.

As response speed falls behind system change, options turn into constraints.

‘Billionaires- the only minority destroying humanity.’

The optimist vs pessimist divide in #climate debates isn’t usually about the data. It’s about how the same graphs are read, what people emphasise, what they discount, and how they interpret pace and stakes. Here’s what I mean 🧵👇

The window for effective action isn’t political. It’s defined by system dynamics and response times.

I actually liked, and still like, the video Simon Clark made with Zeke Hausfather, but Leon Simons do have a valid concern in my opinion. The position presented in the video, plays the usual mediangame, and even worse, downplays scenarios, that is far from excluded, as not realistic.

Gradual change works far from thresholds. Near them, speed determines whether limits are crossed.

As the world quickly approaches 1.5C, researchers have a call in Nature to rethink the utility of temperature targets – and to potentially replace them with more actionable and precise targets around clean energy:

Mathematically "predicting" thresholds for daily, monthly, annual🌡️. 3C by 2050 is upper unc range in IPCC-AR6. Cool chart! At first glance, it's overwhelming. But ~8 seconds in, I can understand and process all info. Tidy, neat, self-explanatory layout and font design. That's a special gift, Rees🏅

In nonlinear systems, delay doesn’t just postpone outcomes. It changes which outcomes become likely.

Speed isn’t just a policy choice. In a destabilizing system, slow responses become a physical risk.

We need a global shift of attitude of ALL nations & segments of society. Climate deniers keep getting voted in at various levels of government. Vote accordingly & get involved by canvassing for political candidates who take climate seriously. As a society, we can fix this but are getting distracted.

Across systems, the pattern is consistent: rising baselines, thinning buffers, delayed signals, and overlapping shocks. Together, they reduce control long before anything “collapses.”

As multiple systems approach their limits, shocks overlap. With a rising baseline, recovery becomes harder each time.

Masking scarcity delays and accumulates shocks — it doesn’t prevent them.

How are scenarios used? Scenarios are used for contrasting purposes but are often actively interpreted and processed by informed users who are aware of different scenarios’ strengths, limitations and uncertainties. www.nature.com/articles/s44... 1/

Price stability can hide physical instability. Scarcity doesn’t disappear just because signals are dampened.

Reactive responses often stabilize prices, not systems. They treat the signal — not the underlying scarcity.

When impacts arrive as prices or shortages, the signal is delayed and distorted. That makes response reactive — and often misdirected.

Climate impacts don’t stay local. Stress on crops like coffee or cocoa shows up elsewhere — as shortages and higher prices.

When stress propagates across systems, causes and effects separate in space and time. That’s why climate impacts are often felt far from where they originate.

A crazy amount of heat has accumulated in the Equatorial Pacific Ocean over the past two months. Hold on to your hats when this reaches the surface with the next El Niño. Y-axis shows depth, X-axis shows degree longitude (one degree equals 111 km) and colors temp anomalies. @noaa.gov PMEL data

Buffers don’t disappear evenly. Stress concentrates where margins were already thin — and that’s where instability emerges first.

In practice, “buffers” often mean simple things: enough water, food, and energy to absorb shocks. Without them, even mild stress becomes destabilizing.

Adaptation works best when systems retain buffers and reversibility. As both erode, adaptation shifts from prevention to damage control.
