Let's not take sides.
Let's listen carefully to those committing genocide about how they feel.
Let's listen carefully to the 21,000 children they murdered.
Then let's all hold hands and make sure nobody feels uncomfortable.

4 science journalists wanted to discuss the ocean in a changing climate. 4/4 linked the idea of removing CO2 from the atmosphere to "solving climate change". 0/4 understood that this is meaningless without cutting fossil fuels. The concept of #NegativeCO2 is being dangerously miscommunicated 🌊

This week I appeared not once, not twice, but three times on TV 😅 Yesterday our 2024 polar work was broadcast on "Cutting edge science". In a 20 minute documentary we answer questions about the fate of pollutants like Pb and Hg in the ocean 🌊

'Crazy Thursday' in China is a popular discount by KFC, so every Thursday many students can be seen tucking into deep fried chicken. This Thursday was also Teachers' Day, so the largest takeout order I've seen was delivered for our staff and students to celebrate together 🍗 😅

One of my friends when I was a student was often in tears. Their boss insisted on a detailed report every week on their progress. If the report was late, they were shouted at.
I would be suprised if these weekly reports achieved anything other than wasting 10% of the group's time.

A jumble of broken ice, and what it means for Greenland’s calving glaciers.
Ice mélange — sometimes known as sikussaq in Greenlandic — is that chaotic jumble of icebergs, bergy bits and sea water that sits in front of marine-terminating glaciers. It’s been described …
