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! 🔥

Melting over 80.6% of the area of the Greenland Ice Sheet. This is the highest value in our data set, which starts in 1981.

@polarportal.bsky.social

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

Torffrei gärtnern. Wichtig.
Aber nicht vergessen:
👉 die größte Menge Torf konsumieren wir durch den Verzehr von Gewächshaus-Gemüse.
Egal, ob aus Spanien, Deutschland oder Niederlande.

Ein wichtiger Hinweis zum Start der Gartensaison - verwendet bitte torffreie Erde!

Hört Euch um, oft könnt Ihr Erde in der Kompostieranlage vor Ort kaufen, unverpackt und wesentlich günstiger 🌻💚

🌍 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.

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).

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?

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.
