The new briefing on solar radiation modification considers the impacts of deploying these techniques globally, looking at effectiveness, limitations, risks, and challenges with monitoring and governance. Read the full briefing here: royalsociety.org/news-resourc...

Thanks to @tinyicybubbles.bsky.social for helping cut this ice! Hoping to get some ages (probably over 400,000 years) from this ice from 651 m deep. @cambridge-earthsci.bsky.social @erc.europa.eu @royalsociety.org

🧊Our researchers have just finished analysing ancient Antarctic ice spanning 1.2 million years of climate history! The Beyond EPICA project extends the ice core climate record by 400,000 years, helping us to understand long-term climate patterns and improve future predictions.

In a UN speech today, President Trump said that "all of these [climate] predictions were wrong". Back in 2019 I led a research effort to digitize old climate model projections and assess how well they did. Turns out they got future warming pretty spot on!

I doubt there is a “cause” for autism, but if I wanted to test for possible contributory factors, I wouldn’t ask an economist or a lawyer. I’d ask a medical scientist who could tell me what the scientific literature tells us. All of it: not just the bit that gives the answer I want to hear.

Today is an important day to speak up for making decisions based on the best scientific evidence. @royalsociety.org

This is part of the BeyondEPICA project. Extremely impressive setup of multiple analysis systems by the team, especially Liz Thomas, Jack Humby, Sarah Jackson et al. @bas.ac.uk

Was extremely exciting today to visit the team melting and analysing Antarctic ice more than a million years old in the BAS CFA analysis campaign. @bas.ac.uk @royalsociety.org

The past two years have witnessed unprecedented extremes in the Antarctic linked to #ClimateChange. Register now for our upcoming discussion meeting to discuss the urgent implications of these changes. You can also apply to present your poster at the meeting: royalsociety.org/science-even...

If anyone is reading, then I have repurposed the Wacswain account to show my name (Eric Wolff). The ERC project has ended, so I can’t claim to speak for its members any more. But I will start posting here again, mainly about science but I may be tempted to give my opinion occasionally as well!

In July 2025, the U.S. DOE released a climate report tied to EPA’s proposed rollback of emissions rules. The report claims to challenge decades of climate science… But scientists say it is unscientific and misrepresents key findings 🧵 science.feedback.org/review/misle...

Our project “BeyondEPICA” collected ice at least 1.2million years old. Now we are meeting at this palazzo in Venice to finalise how it will be analysed to show us the climate and CO2 across this fascinating time period!

Science advances our economic, physical, and social and cultural wellbeing, and is key to a sustainable future. However, we live in times of great change, and the values that have driven science for the benefit of humanity are under threat. Read our statement here: royalsociety.org/news/2025/02...

We have an exciting opportunity for postdoc to join our group at @bas.ac.uk and take part in two big ice core projects: www.beyondepica.eu and @fetch4.bsky.social. Package includes: mugs, stickers, maps, trips to Copenhagen, Grenoble and (maybe) Greenland. bas.ciphr-irecruit.com/applicants/v...

Wacswain is no longer on Twitter/X. Hurrah!

5. The fact that a significant part of WAIS was lost anyway still says we should avoid the climate that caused it. That requires us to reach net zero sooner rather than later.

4. Lessons for the future? This suggests we should expect significant ice loss from WAIS over the next decades to centuries, but makes the very worst case scenarios look slightly less realistic.

3. We find: a. The Ronne Ice Shelf survived b. But the West Antarctic Ice Sheet (WAIS) certainly retreated . So it's good news and bad. The ice sheet retreated but didn't do the worst case that some models proposed. WAIS retreat was probably mainly in the Amundsen sector, not the Weddell.

2. Our article uses the Skytrain Ice Rise ice core to show what happened around the West Antarctic Ice sheet (WAIS) in the last interglacial, 125000 years ago. This is a time when Antarctic temperature was similar to what we expect in the next few decades. What we found follows in number 3.

WACSWAIN has just published the main outcome of our project. Article entitled "The Ronne Ice Shelf survived the last interglacial", out today in Nature www.nature.com/articles/s41... @cambridge-earthsci.bsky.social @royalsociety.org @ercresearch.bsky.social Explanation follows

Our planet's history recorded in ice just got about 50% longer! Beyond EPICA: Oldest Ice have reached the Antarctic bedrock and what is probably the planet's oldest ice - the trapped ancient air bubbles could help us better understand climate change. My story here www.bbc.co.uk/news/article...

Very exciting news from the Beyond-EPICA Oldest Ice project. Ice at least 1.2 million years in stratigraphic order collected from Antarctica. www.bas.ac.uk/media-post/h...

Warm Climate Stability of the West Antarctic Ice Sheet in the Last Interglacial Funded by European Research Council Advanced Grant ERC-AdG-2016 - 742224 Cambridge University, British Antarctic Survey, Royal Society

This is the first post on Bluesky for the Wacswain project. Wacswain is a project funded by the European Research Council. It aims to use ice cores to see how stable the West Antarctic Ice Sheet was in past warm climate.
