When it comes to making progress in climate science collaboration instead of academic competition is the way forward. This was the motto for the recent World Climate Research Program Workshop - "a climate modeling summit" - which we hosted in Hamburg earlier this year. Find out why I believe so👇

Chatted recently with a neighbor about their summer vacation reflections: Neighbor: Weird summer, isn't it. Me: climate change 🙄 Neighbor: Hmm, I remember hot weather when I was a child. Me: Wait until Copernicus issues their update. 👇

🌊 In this study we show that coastal permafrost erosion weakens the Arctic Ocean CO2 uptake by 7-14%. This exerts a weak positive biogeochemical feedback on climate, increasing atmospheric CO2 by 1–2 TgC  per year per °C of rise in global surface air temperature. www.nature.com/articles/s41...

A figure displaying changes in CO2 uptake due to erosion of coastal permafrost from Nielsen et al. 2024.
a, Annual changes in the Arctic Ocean’s uptake of atmospheric CO2 due to coastal permafrost erosion. The shading represents the range of uncertainty stemming from varying OM permafrost characteristics in our simulations, while the solid line represents the mean response. b, Total Inner Arctic Ocean CO2 uptake without coastal erosion (lines) and with coastal erosion (shade). c, Evolution of the Inner Arctic Ocean’s sea-ice area.

P.S. Acceleration of climate change is taking place due to our failure to cut increasing CO2 emissions. Any impact of Arctic coastal permafrost erosion on the global climate through increasing atmospheric CO2 until 2100 is 3-4 orders of magnitude smaller than anthropogenic CO2 emissions.

However, my favorite outcome of this paper is that now we coastal permafrost as a new component of an Earth System Model 😍 allowing for a more comprehensive quantification of the carbon budget, necessary for carbon monitoring under decarbonisation.
