We have reached 1.4 degrees celsius #globalheating according to NASA data (smooth black trend line). Breaching 1.5 is now inevitable. From now on the fight is to keep overshoot as small and short as possible.

I found a dino challenge. Not done with last month's art challenge, no time. But I love #dinosaurs. So I decided to make a very simple animation with today's prompt, Coelophysis, for my dad (today is father's day in my place). I also made a public version:

Koalition einigt sich auf Verkehrsprojekte: Für Autobahnen ist plötzlich Geld da, für die Bahn nicht
Trotz Sondervermögens drohte ein Neubau-Stopp bei Straße und Schiene. Der schwarz-rote Koalitionsausschuss will das verhindern. Doch mehr Geld verspricht Finanzminister Klingbeil nur für Autobahnen.

The federal government has censored the work of dozens of scientists, including work by my lab, on the impacts of climate change on Acadia National Park. Signs have been removed from Cadillac and Great Meadow. They’re also removing signs about the Wabanaki’s sacred connections to Cadillac.
