The Remaining Carbon Budget (RCB) varies with different temperature levels & probabilities, based on Forster et al 2025 (calculation via @robinlamboll.bsky.social).
Though, the variation in the RCB due to non-CO2 emissions spans 1.5°C-1.7°C & many likelihoods.

I don't think people appreciate the extent to which coral reefs are screwed. Even if ocean acidification doesn't get them, increasing ocean temperatures will. How screwed they are is up to us.
There’s no tipping point beyond which ocean acidification kills corals, new research shows. With every creeping bit of acidification, corals just continue to die off. 🧪🌊 eos.org/articles/cor...

As seawater becomes steadily more acidic, complex branching corals die off and are replaced with hard boulder corals and algae.
