When I think about climate change, I think about Venus. Venus was once covered in oceans and rivers of fresh water, about the temperature of a lovely Spring day here on Earth. It then experienced runaway climate change, with its atmosphere trapping more and more heat. Now it’s a hellscape. The temperature on the surface is nearly 500°C all day and night. There’s not a drop of water anywhere. The atmospheric pressure increased to about 90 times what it is on Earth. It would crush a car in less than a second. Nothing can live on Venus.
