In which @madisoncondon.bsky.social and I expand on our argument that "extreme" climate scenarios, such as RCP 8.5, are actually useful and we should use them as part of climate risk analyses. Thanks to @progressivereform.bsky.social for encouraging us and giving us space!

The climate scenario RCP 8.5 is unfairly understood as "misleading," "controversial," or deceptive. This is unfortunate, write @madisoncondon.bsky.social and @vsrikrish.bsky.social — even if its predicted emissions are unlikely, it's incredibly useful for all kinds of climate modeling

A new paper led by @bbastien.bsky.social estimates that accounting for climate pollution's impact on the oceans via the one-two punch of warming & acidification nearly doubles the social cost of carbon (which the Trump EPA thinks is $0). My new @climateconnections.bsky.social article & 🧵 (1/8):

As @bbastien.bsky.social told me, improved estimates of the social cost of carbon are still valuable to other countries, and even state governments. And at some point, a future evidence-based administration will be able to make use of it too. Hopefully before the damages become too great (8/8)

🌊 Accounting for ocean impacts nearly doubles the social cost of carbon By factoring in impacts on corals, mangroves, fisheries, & ports, the 2020 blue social cost of carbon jumps to $48/ton CO2-almost doubling traditional estimates. Protecting “blue capital” matters www.nature.com/articles/s41...

About 150,000 hectares (580 sq. mi.) of mangrove ecosystems, vital for coastal protection, habitat creation, carbon storage, and water quality, will be lost by the end of the century due to #climatechange, with Asia bearing nearly two-thirds of these losses. oceanographicmagazine.com/news/warming...

Warming ocean will cost $28bn a year in mangrove losses alone - Oceanographic

Continued increase in ocean temperatures is projected to stall the advances made in mangrove recovery and restoration, a new study has warned.

I'm pleased to announce our newest paper published at Scientific Data, where we establish a framework for generating fast, custom SRM scenarios. This will allow us to develop probabilístic regional and global impact studies of geoengineering interventions. www.nature.com/articles/s41...

Claim: "Water vapor is a greenhouse gas!" Reality: Yes, and there's more of it in a warmer atmosphere -"CO2 is plant food!" -pretty hard to eat when you're on fire -"Climate has changed before!" -We know, we told you that -"Scientists don't know everything!" - doesn't mean we know *nothing*

Polycrisis isn’t a series of mistakes — it’s a tangled web of crises we navigate through increasingly rough terrain. In this study, we compile a global database and analyze the co-occurrence of shocks, the building blocks of crisis, from 1970 to today. www.cambridge.org/core/journal...
