In London #XR rebels supported Norwegian and Sami activists in the global mobilisation at Hartree offices in London, Oslo, Geneva, Hamburg, New York and Melbourne. A letter was delivered and it is hoped that dialogue will now take place. 2/2 @naturogungdom.bsky.social #reddrepparfjord

In short: the #AMOC is weakening, may collapse this century, &even small shifts could trigger abrupt change These tipping points are a major national security blind spot, threatening food, energy &global stability, they must be addressed urgently As argued here by @laurielaybourn.bsky.social et al

8️⃣ "Subjective probability estimates based on expert opinions are useful & indicate a substantial probability of an #AMOC collapse, particularly under high future warming scenarios." Expert assessments suggest a substantial probability of collapse if warming continues. Action now can reduce risk.

5️⃣ "Because of the possibility of a collapse, the AMOC is one of the most prominent #climate tipping systems, along with the polar ice sheets and the Amazon rainforest." This puts the #AMOC in the same league as the most high-stakes elements of the climate system.

Globally, #climate harms follow patterns. The elderly, the sick, marginalized communities, and the poor are consistently at greater risk. Vulnerability isn’t just exposure, it’s embedded in infrastructure, policy, and social support systems that fail to protect certain groups.
Diagram showing climate vulnerability as the interaction of three components: exposure, sensitivity, and adaptive capacity. Exposure includes the area affected by climate hazards, their severity, and frequency. Sensitivity includes household and community characteristics, housing quality, and access to services and utilities. Adaptive capacity includes mobilizable resources, information and skills, communication, and institutional and social capital. Together, these factors determine overall climate vulnerability.

The optimist green growther outlook assumes that if we fix the climate system then we're good. It's a complete failure of systemic analysis of planetary systems.

And I'd like to add the most important 'pessimist' point of all: even if we do continue with exponential renewables addition and replace instead of add to ff energy, we're over planetary boundaries in other systems and growing 'green' energy and material throughput will only make that worse.

I feel called out because I solidly agree with the 'pessimist' framing in each of your examples. I have to say I'd call it 'realist' not pessimistic. I retain stubborn optimism that we can still do better, but the optimist framing feels unrealistic given how much faster we need to transition.

11/ Until we name that, this argument will keep looping. I find myself cautious when interpreting these trends: progress exists, but limits are real and urgent, and much more could be done to reduce unnecessary harm.

10/ The optimist–pessimist divide isn’t just about hope or despair It’s about interpreting uncertainty & which risks we consider acceptable when some outcomes are far worse than others Scenario-based projections amplify room for multiple readings depending on the counterfactuals we deem plausible

9/ This matters because climate communication often treats disagreement as a knowledge problem. But many people aren’t confused about the data. They’re weighting momentum vs limits, trends vs risk, improvement vs sufficiency, differently.

8/ Taken together, these graphs show why the debate doesn’t resolve. Optimists tend to read the data dynamically: Are things moving in the right direction? Are reinforcing effects kicking in? Pessimists read it physically: Are we within limits? Is change fast enough to avoid irreversible harm?

7/ Projected warming under current policies O: We’ve moved past worst-case futures. Policy matters; agency shows in the numbers P: 2.5–3°C is devastating. We’ve failed to hold warming to 1.5°C & science shows impacts arriving sooner & hitting harder than models projected. Assumes promises are kept

6/ Global energy investment Optimist: Most new investment now goes to clean energy. Capital is reallocating. The transition is being built. Pessimist: New investment is still being poured into fossil fuels. Capital is actively expanding the system driving the #ClimateCrisis, not just lagging.

5/ Renewables as a share of total energy Opti: This is early exponential growth. As renewables scale, substitution will accelerate. Primary energy understates progress: much fossil energy is wasted Pessi: The denominator matters: fossil energy isn’t shrinking. Additive growth isn’t displacement

4/ Carbon intensity of the economy Opti: The economy emits less CO₂ per unit of output. Efficiency & cleaner power decouple growth from emissions Pessi: Lower carbon intensity can mislead: energy use & demand often rise, so emissions keep growing. Efficiency lowers intensity, yet problem persists
