On the train home to Lund after a wonderful day in Stockholm, marching for the climate with at least 50,000 other people - including my friend and colleague @mogren.ml. Walked among others with @researchersdesk.bsky.social. I hear this may have been the largest climate march in Swedish history!

City farm initative update: Today we built a cardboard island - but before that we removed 2+ bags worth of tape/plastic from the cardboards. Tomorrow we'll get manure to spread on the island, after which we can plant the potatoes that are currently sprouting in the old barn.
