Five years ago today, most historical UK monthly rainfall observations were not available to scientists. But the 66,000 pieces of paper containing the data had been scanned. With covid lockdown approaching we saw an opportunity to transcribe the data. #RainfallRescue began... 🧵

If greenhouse gas emissions are not cut drastically soon, he Swiss glaciers could cease to exist by 2100 – so says ETH Professor Daniel Farinotti in this ETH News interview #WorldDayOfGlaciers ethz.ch/en/news-and-...

To be clear: this would mean the *increment* of the increase in 2024 is itself the largest on record (in addition the value being the highest on record, which unfortunately happens essentially every year in our rapid warming era). That's...not great (as Glen discusses downthread).

Our new Nature Communications paper, led by Timo Kelder with coauthor Lisette Klok and an incredible team, explores how we can anticipate extreme weather before disaster strikes and build resilience to its impacts. 📽️ Watch this short video to learn more! 👇@naturecomms.bsky.social

How Switzerland cleaned up its rivers and lakes. This success story is encouraging when we address the next step: improving river morphology and riparian vegetation in a warming world. www.theguardian.com/environment/...

Another fantastic product that came out of the 2024 US CLIVAR workshop on Confronting Earth System Model Trends with Observations: The good, the bad, the ugly. Check it out!

Can climate models reproduce observed trends? The answer can be challenging. Our new review paper in Science Advances led by Isla Simpson and Tiffany Shaw @drshaw.bsky.social discusses challenges and ways forward in confronting climate models and observations. www.science.org/doi/10.1126/...

1/ How to Stop Being Surprised by Unprecedented Weather Our new @naturecomms.bsky.social paper provides our multi-author perspective on methods to anticipate extreme weather and reduce impacts, shifting from reacting with surprise towards resilience. 🔗 Read it here: doi.org/10.1038/s414... 🧵⬇️

How to stop being surprised by unprecedented weather? Transformative adaptation, foundation for long-term resilience, supported by incremental adaptation through upgrading existing infrastructure, and reactive adaptation - early action and disaster response. www.nature.com/articles/s41...

We have seen many record-shattering and unprecedented weather extremes in recent years. In the paper led by @timokelder.bsky.social we review methods on how to stop being surprised by the next one.

📢 Postdoc Opportunity: Ocean Tipping Points & Impacts! We're hiring a postdoc in my group at the University of Bern, Switzerland, to study ocean tipping points and their impacts. The position is part of HEurope project TipESM (@tipesm.bsky.social). Feel free to reach out with any questions. 🌊

ETH Zurich scientists #StandUpForScience2025 in support of our US colleagues. Thanks @soniaseneviratne.bsky.social for spontaneously organizing this.

AGU has joined a lawsuit challenging the firing of probationary employees at federal agencies. These actions weaken science, harm public health & the environment, and threaten national security. 🧵 #StandWithScience

🚨 #NOAA is essential for weather forecasting, climate research, and public safety. AGU stands with the scientific community in urging Congress to protect and strengthen NOAA, not dismantle it. Our economy, environment, and safety depend on it.

Es kam sehr überraschend: Am Donnerstag fiel der Entscheid der SRF aus Spargründen das "Wissenschaftsmagazin" zu streichen. Zusammen mit anderen Forschern (u.a. @erichfischer.bsky.social @florianaltermatt.bsky.social) habe ich meine Bedenken geäussert www.srf.ch/audio/wissen...

The extreme winter warming event continues in the northernmost portions of the #Arctic. This is related to a temporary surge of heat and moisture that was transported northward and is related to the orientation of the large-scale atmospheric circulation. Graph from zacklabe.com/arctic-tempe...

A lot of folks asked why I through this January's record global temperatures were so unexpected. I think this graph shows it pretty clearly: pretty much every other January with La Nina conditions has been a cooler than the surrounding years.

We are alarmed by the Administration’s actions to freeze science funding and eliminate DEI efforts and climate change initiatives, which go against AGU’s mission and harms our members. We must unite to address these changes, beginning by hearing from you. Read more: https://buff.ly/4hm8r4e

Same. Yesterday in my last lecture of the semester, we discussed the importance of defending science and knowledge against the rising threats globally. CO2 will keep rising if we don't do anything about it, and it will keep warming the planet. With or without a website. It's just plain physics...

“This was a very extreme winter warming event,” said Mika Rantanen, a scientist at the Finnish Meteorological Institute. “Probably not the most extreme ever observed, but still at the upper edge of what can happen in the Arctic.” #Arctic @mikarantane.bsky.social

Das Kaspische Meer hat keine Verbindung zu Weltmeeren. Dessen #Wasserspiegel ist in den letzten 20 J. um 2m gesunken. "Je nachdem, wie stark die #Erderwärmung zunimmt, könne er in den kommenden Jahrzehnten um weitere 6 bis 14 Meter sinken", sagt @erichfischer.bsky.social. www.srf.ch/news/wirtsch...

In @wwattribution.bsky.social report on the LA wildfires this January we show the frequency and intensity of the atmospheric circulation of the event has increased in winter, raising the risk of weather conditions that drive the spread of wildfire. www.worldweatherattribution.org/climate-chan...

Very sad news: Linda Mearns passed away last night. A huge loss to her many friends and colleagues, and a tremendous loss to science. She research and insights improved the lives of millions. Her intelligence, humor, and obsession with uncertainty will always be remembered.

Storm #Éowyn has set new wind speed records for Ireland as potential sting jet hits the west coast (mean wind 37.5 m/s & gust 50.8 m/s). The location of the maximum winds and the satellite appearance of #Éowyn match with the conceptual model of a sting jet.

First time experiencing an operational emergency alert in the UK! Hearing everyone’s phones blasting the alert sound just reminds me of storm chasing in the US

Storm Éowyn at 949 hPa at 18Z, with the Met Office analysing a frontolysing cold front with frontal fracture — a powerful Shapiro-Keyser cyclone (as opposed to a standard Norwegian cyclone)

In a new concept paper following the @wcrpclimate.bsky.social Open Science Conference, we examine links between climate science and decision making regarding extremes and risks. Enhancing these links requires better integration of climate sciences and impact sciences for actionable climate info. 1/3

We have our first projection of 2025 annual temperatures out from the UK Met Office. They expect it to be slightly cooler than 2023, albeit with wide uncertainties, but to remain far above any prior year in the observational record: www.metoffice.gov.uk...

Guardian coverage of our #AGU24 session from Tuesday. www.theguardian.com/environment/...

It is always mind boggling at how massive @agu.org is every year. This is just one session of the poster room, which changes over twice daily for the duration of the conference. #AGU24

Sometimes Net-Zero CO2 seems centuries away, e.g. when on your AGU morning run on Capitol Hill you see tens of these lamps powered by an individual diesel generator each…

News from @copernicusecmwf.bsky.social: 2024 is on track to become the warmest year on record both globally and in Europe. Interestingly, this is the first time that both regions will be record-warm in the same year.

If you are at #AGU24, come by poster GC-0263 this afternoon. Devin Rand & I will be discussing an exciting new data product Berkeley Earth will soon be releasing, our Climate Model Synthesis: berkeleyearth.org/climate-mode... A downscaled & observationally-constrained synthesis of CMIP6 models.
