Reposted by Andrew PatrickZeke Hausfather @zekehausfather.com · 22/09/2026So while we think we are heading toward ~3C today, we could really end up at 4C if we role 6s on the proverbial climate dice. Its more useful to treat climate outcomes as a set of risks – the odds of the world warming by 2C, 3C, or 4C over time – rather than a deterministic outcome. 25714
Reposted by Andrew PatrickZeke Hausfather @zekehausfather.com · 22/09/2026These arise from two factors: carbon cycle feedbacks – how the biosphere and ocean's ability to absorb carbon changes as we emit more and the world warms, and climate sensitivity – how the interplay of feedbacks like water vapor, clouds, snow and ice, etc. respond to warming. 1429
Reposted by Andrew PatrickZeke Hausfather @zekehausfather.com · 22/09/2026We hear a lot about central outcomes of climate change. For example, under the new "medium" scenario (e.g. current policies continuing), the world warms around 2.9C by 2100. But these numbers mask some massive uncertainties in how the climate actually responds to our emissions. 1325
