Fantastic workshop yesterday led by @timgbenton.bsky.social imagining our possible environmental futures with a team from across the university. Thought provoking and sobering.

A rare moment of how I always imagined university should be! You know it has been good when 4 hours goes in a flash

A future scenario for planet Earth - self-sufficiency for security. An unstable conflict-ridden world with countries retreating into isolationism.

What I called the 1984 scenario

Not even close 😥 I tried to show the size of removals given a delay in this animation 👇 related to the amount of BECCS assumed in size of EU (note that this is for a 67% chance not a 50% chance as per Glen's figure). Used Climate Action Tracker for the national targets.

Summer UK temperatures have warmed faster than global average temperature.

But the very hottest days have warmed 4x faster than the global average, especially in south-east England.

Global warming is not "just" 1°C or 2°C. The effects of climate change are non-linear, especially for extremes.

Maps showing warming for each UK county for typical summer days (left) and hottest days (right), with darker reds and faster warming for the hottest days especially in south-east England.

New paper by Sebastian Sippel and colleagues provides evidence that the SST component of most current global temperature datasets is too cold during (roughly) 1900-1930.

Important new study shows that current climate models underestimate the human-caused slowing of the #AMOC (Atlantic Meridional Overturning Circulation), because they neglect freshwater influx from Greenland melt and other sources. /1 🌊

Fresh meltwater entering the Labrador and Irminger seas has resulted in a slowing of the Atlantic Meridional Overturning Circulation since the 1950s, according to a combination of modelling approaches...
