#EGU26 #AtmosphericRivers

This session provides a comprehensive platform for discussing the latest advances in atmospheric river (AR) science. We invite all contributions that aim at a better understanding of AR uncertainties, processes, and impacts across past, present, and future climates.

🌍 Call for Abstracts: Session AS1.34 at EGU General Assembly 2026

We are excited to invite you to submit your abstract to our session at the EGU General Assembly 2026:

🌧️Atmospheric rivers: Understanding their processes and impacts across past, present, and future climates (AS1.34)🌧️

While the very same „deadly rivers“ are also vital resources of freshwater, I really appreciate a global perspective on the hazards they can cause. In this sense, it’s our actions today that that bring about the floods of tomorrow.

Deadly rivers in the sky A new Washington Post investigation reveals where climate change has supercharged the movement of moisture through the skies.

A great article by the @washingtonpost.com which I’m excited to have contributed to!💦💨
It has really powerful interactive visualisations of how a warming planet is also a moistening planet on which more precipitation-induced disasters strike regions all around the globe🌎

Thanks for having me & showing me all the really cool research you’re doing in Valencia!🙌🏻🌏

… we reconstruct temperatures & seasonality from a stalagmite collected in Arctic Siberia, dating 9Ma back. While global average temperatures back then were around 4.5 °C - similar to future high emissions scenarios - Arctic temperatures could have been as high as +11.1 °C (−12.3 °C today). (2/3)

An Arctic warming of > 18 °C far surpasses what models predict and holds vital implications for vulnerable Arctic permafrost soils. (3/3)

Speleothem evidence for Late Miocene extreme Arctic amplification – an analogue for near-future anthropogenic climate change? Abstract. The Miocene provides an excellent climatic analogue for near-future runaway anthropogenic warming, with atmospheric CO2 concentrations and global average temperatures similar to those projec...

The Arctic is warming roughly 4x faster than the rest of the planet. How do we know how fast it will warm in the future? Models, alright, but palaeo-analogues from the deep past offer real data! In our new study… (1/2)

🌍 Fresh dataset of atmospheric rivers just dropped!
After 3 years of work, we proudly present PIKART — 8 decades of user-friendly global AR data.
We really hope it can help to better understand water transport & climate impacts 💨💧

Great to see our work in @eos.org ! A good read for the evening! 😇 kudos to all our friends & colleagues that contribute to this ongoing endeavour - there is so much to learn! 🤩 together - always! @thomasopel.bsky.social @juvmcburst.bsky.social @pucicu.de @scitobias.bsky.social @leverhulme.ac.uk

Back to good old Austria Center Vienna for the European Space Agency’s Living Planet Symposium #LPS25. After a grand opening yesterday, I‘m curious to learn more about Earth Observation & discuss science! 🌎 🛰️

With its 21k attendees, #EGU25 can really feel a bit overwhelming at times😵‍💫 But it’s also an awesome opportunity to catch up with
science friends & check out loads of cool research! 🌍

Thanks to all attendees & everyone presenting exciting research in last Friday‘s first-ever #EGU25 session on Atmospheric Rivers! See you next year! #atmosphericrivers

Early-twentieth-century cold bias in ocean surface temperature observations - Nature Independent statistical reconstructions of the global mean surface temperature from either ocean or land data show that existing estimates of early-twentieth-century ocean surface temperatures are too...

A new paper led by Sebastian Sippel just appeared in Nature arguing that ocean temperature measurements in the early 20th century have a cold bias.

It's a fun story illustrating the process of scientific discovery, so let me talk about it a bit. 🧵

Why did so many die in Spain? Because Europe still hasn't accepted the realities of extreme weather | Friederike Otto Severe flooding is, unfortunately, inevitable. What isn’t inevitable is how ready we are, says Friederike Otto of World Weather Attribution

We Europeans need to practice survival in a rapidly changing climate - my opinion piece, focussed on Spain, but could equally have been written 3 years ago after the deadly floods in Germany . We've not learned enough & that costs lives and livelihoods. www.theguardian.com/commentisfre...
