90 Degrees in Winter: This Is What Climate Change Looks Like

The sky is falling

It is a fact that clouds are thirty meters lower now than ten years ago. This is not because of magnetic changes. It is because the atmosphere is shrinking, so clouds are naturally lower. When leaving San Jose, Costa Rica, I looked down from the small mountain to see the city below. To see it I had to look through clouds. The atmosphere is shrinking because the excess CO₂ is heavy and lies on the ocean and is absorbed. This causes acidic oceans and harms some fishes. Fish stock are shrinking all over the world. Sure, there is massive overfishing as well.
