I’m a climate scientist. Let me fix this headline. “Nearly a century ago, scientists showed that burning fossil fuels warms the planet. Today, we know human emissions account for over 100% of the warming. Yet dark money and disinformation still work to keep Americans addicted to fossil fuels.”

Scientists have reached a consensus that human behavior is a big driver of climate change—but Americans aren't buying it.

Hybrid lead halide perovskites often behave weird. One of the reasons for that is that typical perovskite thin films contain a whole zoo of microscopic structures that affect electronic and ionic charge transport. (1/5)

This iridescent, dendritic (from the Greek word dendron, meaning tree) #perovskite likely formed from volcanic gases released from a volcanic vent, or fumarole. This crystal is from the Eifel Mountains, Germany. Perovskite can be beautiful! More on dendritic crystals in the comment. #MinCup25 ⚒️

Perovskite from Rother Kopf Mountain, near the community of Roth in the town of Gerolstein, also in Rheinland-Palatinate’s span of the Eifel Mountains. (Photo: Fred Kruijen) This crystal looks like a iridescent tree branch made of rectangular crystals.

The volume of mining and material use with EVs and renewables is massively in favor of clean energy, mainly because you can reuse batteries for decades and then recycle them. Oil, gas, and gas must be constantly moved.

»Für Hitler und seine Anhänger gibt es auf dieser Erde keine Strafe, die ihren Taten gerecht wäre.« Hans Scholl auf einem Flugblatt der ‚Weißen Rose'. 22.9.1918 - 22.2.1943

Das Cover eines Buches über Hans Scholl. Die Biografie zeigt auch die Brüche seines Lebens auf und ich finde sie lesenswert.

Sophie Scholl am Tage ihrer Hinrichtung: „So ein herrlicher Tag , und ich soll gehen. Aber was liegt an unserem Leben, wenn wir es damit schaffen, Tausende von Menschen aufzurütteln und wachzurütteln.“

Ein Foto von ihr mit langen Haaren. Sie trägt eine Strickjacke, hat eine Margerite  sich an die Bluse gesteckt. Schaut skeptisch ihr gegenüber an.
