Most of these damages come from non-market values: nutrition, coastal protection, and the existence value of marine ecosystems — not just market losses.

Our central estimate is $48 per ton of CO₂ (2020 USD) — which roughly doubles the SCC of the model without ocean damages. But here is a fuller comparison using other discount rates and baseline damage functions.

Figures looked weird, so sharing again!

Together:
🌍 Socioeconomics push toward recovery.
🔥 Warming oceans stall or reverse progress.
Without climate change, mangroves could recover to global restoration targets. With warming, we lose ~150,000 ha by 2100.

Temperature matters too.
Warming helps colder sites expand. But beyond a threshold, heat damages dominate.
We identified sea surface temp of the hottest month (SSTh) as the strongest signal.
This Figure shows the marginal effect of both drivers

Mangroves protect coasts, store carbon & sustain fisheries. Using global data (1996–2020), we mapped mangrove extent & tracked how it responds to climate & socioeconomic drivers. Each point = 1° grid cell with mangroves.

After months held up in customs, @paulkelleher.net 's book finally made it to me. Now riding along with me on the Mexico City metro.

New paper!
Polycrisis isn’t a series of mistakes — it’s a tangled web of crises we navigate through increasingly rough terrain.

What a view of the Sandia mountains last week in Albuquerque. So happy to join the @aereorg.bsky.social scholars cohort, an amazing group of supportive and brilliant people!

What an amazing week at the Beijer Institute, Royal Swedish Academy of Sciences!
Sharing ideas, methods and good moments with this talented group of scholars studying socioecological impacts.

In an activity of naming ocean-based values that I've been doing for a while in some classes, the top words historically have been 'food' and 'recreation' 🌊
I was happy to see a new word emerging today: 'peace'.
Naming what we value is the first step to including it in environmental policy

So stoked about artists illustrating our recent paper on climate-driven ecosystem range shift and economic impacts.
