🌊 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.

It is great to see that an image featuring our paper 'Reduced Arctic Ocean CO2 uptake due to coastal permafrost erosion' led by David Nielsen has been chosen as cover art work in this month's Nature Climate Change 🥳

Same here, it’s like meeting all those I knew from before plus so many new people. This is exciting.

Thank you! Yes, David's starter packs are very useful to get started here.

This new ICON-XPP model is our working horse for the upcoming CMIP7 climate projections. It will also remain the horse we are working on for a while 😉 At an all-hands workshop at the Seewetteramt #Hamburg last week we discussed progress and challenges. Dr. Barbara Früh presenting the new project👇

Dr. Barbara Früh presenting the new project CAP7, which she coordinates. The project will enable the German contribution to CMIP7.

What if we could start a weather simulation and let it run over seasons, years, decades, centuries ... This is at the heart of the ICON-Seamless Project developing a new generation Earth System Model ICON-XPP suitable for weather and climate forecasts. www.dwd.de/EN/research/...

These novel simulations will contribute to CMIP7 which will respond to the needs of IPCC AR7. P.S. I left the job description somewhat broad to leave space for candidates' creativity in shaping the focus of their analysis.
