Satellites confirm 1990s sea-level predictions were shockingly accurate Satellite data reveals sea-level rise has unfolded almost exactly as predicted by 1990s climate models, with one key underestimation: melting ice sheets. Researchers stress the importance of refining ...

Sea level projections from the 1990s were right.

Being on social media is fine but if it’s getting in the way of you doing deep reading and deep thinking, then your balance of how you spend your time is off

Lots of interesting threads here and none of them are a substitute for reading a good book or essay

Incredible serac fall from Hengsteren Glacier on Wetterhorn (3,690 m, Grindelwald) 🧊

37 degrees in the valley yesterday when this serac carve off 🥵

Meanwhile on the Monta Rosa the same day the temp at 3500m was between 6 and 13°C! 🔥

Screenshot from polarportal.dk, a website that makes research on the Arctic research conducted by Danish institutions available to the public and researchers. The image shows Greenland in tan and the Greenland Ice Sheet in red and white. The red part indicates melting and covers all except about 20% in the northeast, which is roughly the area higher than 2500 m above Se level. Below the map is a chart that compares 2025 melting to the 1981-2010 average. The average melting peaks in mid-July at about 35%. For the last few days, melting has occurred over roughly 80% of the area of Greenland, with a maximum melt area of 80.6% on 24 July 2025. This is the highest value in our dataset, which starts in 1981.

Writing is hard because the process of getting something onto the page helps us figure out what we think—about a topic, a problem or an idea. If we turn to AI to do the writing, we’re not going to be doing the thinking either. (Rosenzweig 2023)

Can we infer fire intensity from charcoal counts alone in #palaeoecology? Most possibly not! Using several charcoal-based methods & novel Raman spectroscopy we recommend using several #paleofire methods for more informative past fire reconstructions

I did the same and I'm very happy with my decision!

There was so much going on #peatland & #palaeoecology-wise at the #EGU25 this year! Lots of great talks, posters, discussions, gatherings... 😊 As I have almost 0 photos from the congress, here you go, a beautiful finding from a quick visit at @leopoldmuseum.bsky.social, a wetland by Carl Moll

Our new paper in @pnas.org shows how the first Polish dynasty established a state and later, due to social and ecological imbalance, orchestrated its colapse.

🌍 Global peatland drainage - 3 key facts🌱

1️⃣ Artificial drainage damages peatlands and their ecosystem services.
2️⃣ Drained peatlands are more susceptible to flooding and burning.
3️⃣ 85% of drained peatlands are located in Europe and Southeast Asia.

On the one hand, I’m appreciating all the conversations about the turning point in social media, and that more people are quitting for more generative spaces like blogs and newsletters. On the other hand, that only works if you have an audience (often built on social media) to follow you there.

Great idea! 🙃 You can add me to if it's not a problem.

Hello, so, I'm an anthropologist who has studied wildfires for over a decade and, just recently, handed in a book manuscript for peer review on the pathologies of wildfire management in Australia and, to a lesser extent, Canada and the US. It's called "How to Control Fire" (TBC).

There's still a few days left to submit your abstract for the #EGU25. If you didn't decide yet on the suitable session for your #peatland #palaeoecology contribution consider our session on long-term peatland records!

Cameron, Ariz. Living on one of the largest swaths of land in America without electrical power, Thomasina Nez's entire life is a scramble to complete basic tasks. To take a hot shower, she must wait for buckts of water to come to a boil on a small propane stove outside her wood framed roundhouse. To make meals, she relies mostly on canned goods because unfridgerated produce rots qucikly in the Arizona heat. Its a struggle to stay warm at night, because she refuses to use her coal-powered heate after its fumes killed her two dogs.

A fierce battle for electric power is being waged across the nation, and Nez is one of thousands of people who have wound up on the losing end. Amid a boom in data acenters, the energy intensive warehouses that run supercomputers for Big Tech companies, Arizona is racing to increase electricity production. In February, the state utility board approved an 8 percent rate hike to bolster power infrastructure throughout the state, where data centers are popping up faster than almost anywhere in the US But it rejected a plan to bring electricity to parts of the Navajo Nation land, concluding that electric consumers should not be asked to foot the nearly $4 million bill.

I know academics who use AI regularly, for work and play, and I'd really like them, and universities, to tell me how they contend with AI's bottomless appetites for power and water.

Is asking ChatGPT to interpret a Xmas song or making it write your syllabus worth this to you?

Female Foundations: The Lives and Legacies of Women in Earth Sciences CALL FOR PAPERS *EXTENDED DEADLINE* We are hosting a day school to coincide with International Women’s Day 2025 on 8 th March 2025 in Dorchester, Dorset, UK. We welcome proposals for papers that celebrate individual or collective women’s contributions to science (broadly defined), with a focus on how their work, research or scientific endeavour enabled a progression of ideas or shift in practice within their field. We are therefore not inviting purely historical accounts, but how a past or current woman’s work has been influential and why we should celebrate them. We are delighted that the award-winning author Tracy Chevalier, will be joining us to talk about her work on Mary Anning. We invite abstracts (c. 150-250 words) for oral papers of a 20 minute duration, by 30/12/24 to anne@pastparticipate.co.uk
