Don't forget the next SMILE webinar is tomorrow!

Our new paper is out today. I led this project to refine future hydroclimate uncertainties in Central Europe based on large ensembles. link.springer.com/article/10.100…

Our new paper on tropical forcing of jet stream waviness is out today in Nature Communications nature.com/articles/s4146…

A better representation of wind-driven warming processes in models has potential for lessening sea-level rise projections uncertainties associated with Greenland melt. 👉👉 out today Nature Communications with Xavier Fettweis Zhe Li and others not on twitter nature.com/articles/s4146…

Bad news: emissions-driven wind changes are likely not well enough represented in climate models. Good news: when correcting for this issue, the first occurrence of a sea-ice-free Arctic is actually delayed. More details in NatureClimate Free access: rdcu.be/deluw

Sea Ice Is Going, but When Will It Be Gone? A nice comparison of Min et al. and our work 👇 eos.org/articles/sea-i…

We highlight tropical Pacific drivers of Arctic and Greenland ice loss. Convection changes (lower frequency than ENSO) in the tropics is key to drive atmospheric Rossby-waves into the Arctic, but these low frequency changes are not fully captured in CMIP. nature.com/articles/s4155…

The ‘Polar Amplification and lower latitude connections’ AGU23 session already has a nice lineup of abstracts (incl mine 😏). Submissions are still open until 2 Aug, consider if interested👇🏼 session by Prof James Screen Yutian Wu Lantao Sun Qinghua Ding agu.confex.com/agu/fm23/preli…

Honored to have received the young researcher award 2023 of the V4 countries’ academies for my research in the context of polar climate change.

The conclusions about caution of model projections due to dynamical biases are much in line with what we know for Arctic sea ice ( nature.com/articles/s4155… )Could be interesting if there is a common driver behind underestimated dynamics in models between the Arctic and midlat too

Out today! Our new Review paper in Nature Reviews Earth & Environment 🌈 "Short- and long-term variability of the Antarctic and Greenland ice sheets" nature.com/articles/s4301…

Happy to have been involved in this review led by Prof. Edward Hanna . Thanks to all coauthors , I too learnt a lot in the process.

New study: the Atlantic overturning circulation AMOC “is on tipping course”. The paper by Dutch colleagues adds more weight to recent warnings, such as the OECD Climate Tipping Points report of 2022 and the Global Tipping Points report published 2023. realclimate.org/index.php/arch…
