Prof. Tatiana IlyinaWhat 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 <a href="https://mas.to/tags/EarthSystemModel" class="mention hashtag" rel="nofollow noopener" target="_blank">#EarthSystemModel</a> suitable for <a href="https://mas.to/tags/weather" class="mention hashtag" rel="nofollow noopener" target="_blank">#weather</a> and <a href="https://mas.to/tags/climate" class="mention hashtag" rel="nofollow noopener" target="_blank">#climate</a> forecasts.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 😉At an all-hands workshop at the Seewetteramt <a href="https://mas.to/tags/Hamburg" class="mention hashtag" rel="nofollow noopener" target="_blank">#Hamburg</a> last week we discussed progress and challenges. <a href="https://social.bund.de/@DeutscherWetterdienst" class="u-url mention" rel="nofollow noopener" target="_blank">@DeutscherWetterdienst</a>

Prof. Tatiana IlyinaAcceleration of <a href="https://mas.to/tags/climatechange" class="mention hashtag" rel="nofollow noopener" target="_blank">#climatechange</a> is taking place due to our failure to cut increasing CO2 emissions.Any impact of Arctic coastal <a href="https://mas.to/tags/permafrost" class="mention hashtag" rel="nofollow noopener" target="_blank">#permafrost</a> erosion on the global <a href="https://mas.to/tags/climate" class="mention hashtag" rel="nofollow noopener" target="_blank">#climate</a> through increasing atmospheric CO2 concentrations until 2100 is comparatively small. Yet, this new <a href="https://mas.to/tags/EarthSystemModel" class="mention hashtag" rel="nofollow noopener" target="_blank">#EarthSystemModel</a> component allows for a better quantification of the carbon budget, necessary for carbon monitoring under <a href="https://mas.to/tags/decarbonisation" class="mention hashtag" rel="nofollow noopener" target="_blank">#decarbonisation</a> .Read more in this press release 👇 <a href="https://www.uni-hamburg.de/en/newsroom/presse/2024/pm40.html" rel="nofollow noopener" translate="no" target="_blank">https://www.uni-hamburg.de/en/newsroom/presse/2024/pm40.html</a> <a href="https://mas.to/tags/ilyinaScience" class="mention hashtag" rel="nofollow noopener" target="_blank">#ilyinaScience</a>

Prof. Tatiana IlyinaIn a <a href="https://mas.to/tags/newpaper" class="mention hashtag" rel="nofollow noopener" target="_blank">#newpaper</a> from my group, led by David Nielsen, we incorporated coastal permafrost as a new component of an <a href="https://mas.to/tags/EarthSystemModel" class="mention hashtag" rel="nofollow noopener" target="_blank">#EarthSystemModel</a>.This allowed us to quantify that <a href="https://mas.to/tags/coastal" class="mention hashtag" rel="nofollow noopener" target="_blank">#coastal</a> <a href="https://mas.to/tags/permafrost" class="mention hashtag" rel="nofollow noopener" target="_blank">#permafrost</a> erosion weakens the Arctic Ocean <a href="https://mas.to/tags/CO2" class="mention hashtag" rel="nofollow noopener" target="_blank">#CO2</a> uptake from the atmosphere by 7-14%. This exerts a positive biogeochemical feedback on <a href="https://mas.to/tags/climate" class="mention hashtag" rel="nofollow noopener" target="_blank">#climate</a>, increasing atmospheric CO2 by 1–2 TgC yr−1 per °C of increase in global surface air temperature.Find out more here👇 <a href="https://www.nature.com/articles/s41558-024-02074-3" rel="nofollow noopener" translate="no" target="_blank">https://www.nature.com/articles/s41558-024-02074-3</a> <a href="https://mas.to/tags/ilyinaScience" class="mention hashtag" rel="nofollow noopener" target="_blank">#ilyinaScience</a>

Prof. Tatiana IlyinaWhat happens after a snowball Earth melts?With the new <a href="https://mas.to/tags/EarthSystemModel" class="mention hashtag" rel="nofollow noopener" target="_blank">#EarthSystemModel</a> ICON, we find that the supergreenhouse climate was not necessarily a stable and hot climate over hundreds of thousands of years. It is also possible that the temperatures were moderate and even declined rapidly, on a time scale of just a few thousand years, in response to changes in the ocean C-cycle.Find out in this news piece👇 <a href="https://mpimet.mpg.de/en/communication/news/was-passiert-wenn-eine-schneeball-erde-schmilzt" rel="nofollow noopener" translate="no" target="_blank">https://mpimet.mpg.de/en/communication/news/was-passiert-wenn-eine-schneeball-erde-schmilzt</a>with more details in our new paper👇 <a href="https://doi.org/10.1038/s41467-024-47873-6" rel="nofollow noopener" translate="no" target="_blank">https://doi.org/10.1038/s41467-024-47873-6</a>

Prof. Tatiana IlyinaOnce upon a time, only about 650 million years ago, our Earth was a snowball. What was the aftermath <a href="https://mas.to/tags/greenhouse" class="mention hashtag" rel="nofollow noopener" target="_blank">#greenhouse</a> <a href="https://mas.to/tags/climate" class="mention hashtag" rel="nofollow noopener" target="_blank">#climate</a> triggering deglaciation and the ocean's role in it? We addressed this intriguing scientific question via a set of <a href="https://mas.to/tags/EarthSystemModel" class="mention hashtag" rel="nofollow noopener" target="_blank">#EarthSystemModel</a> experiments in the new Nature Communication paper "Moderate greenhouse climate and rapid carbonate formation after Marinoan snowball Earth" led by Lennart Ramme within his PhD project.<a href="https://doi.org/10.1038/s41467-024-47873-6" rel="nofollow noopener" translate="no" target="_blank">https://doi.org/10.1038/s41467-024-47873-6</a>

Prof. Tatiana IlyinaHave a look at our simulation of the air-sea <a href="https://mas.to/tags/CO2" class="mention hashtag" rel="nofollow noopener" target="_blank">#CO2</a> flux and surface wind speed in a high-resolution <a href="https://mas.to/tags/EarthSystemModel" class="mention hashtag" rel="nofollow noopener" target="_blank">#EarthSystemModel</a> model ICON 👇 <a href="https://youtu.be/63NZSPjxv6w" rel="nofollow noopener" translate="no" target="_blank">https://youtu.be/63NZSPjxv6w</a>I find September particularly fascinating in this animation. A hurricane in the Western Atlantic entirely messes up the CO2 flux. Here, the immediate effect is that the hurricane enhances the outgassing of CO2. Behind it, the flux swaps the sign and there is uptake of CO2.<a href="https://mas.to/tags/ilyinaScience" class="mention hashtag" rel="nofollow noopener" target="_blank">#ilyinaScience</a>
