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.”

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 ⚒️

Quotes from Albert Einstein, Hannah Arendt, Gustave Gilbert, and Elon Musk, next to drawings of each in pencil style by Patt Bagely. In sequence: "empathy is patiently and sincerely seeing the world through the other person's eyes." - Einstein. "The death of human empathy is one of the early and most telling signs that a culture is about to fall into barbarism." - Arendt. "It is one of characteristic that connects all the defendants -- a genuine incapacity to feel with their fellow men. Evil, I think, is the lack of empathy." - Gilbert. "The fundamental weakness of western civilization is empathy." - Musk

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.
