Earth's clouds are shrinking, boosting global warming

Earth gets over 170,000 terawatts of solar energy every day—10,000 times more than humanity uses. Losing just a fraction of our cloud cover means a massive, invisible throttle is coming off the climate system. If this trend holds, we’re not just warming—we’re stepping on the gas.

terawatt is not an energy unit.

I like the use of watts/day instead of joules here because we have some intuition about watts. Earth must dissapate 170 exawatts per day of sunshine, in addition to letting off some amount of heat from the molten core.

(Life has evolved on the edge of a knife, at the narrow balance point between enormous energies that cancel out just so. I often think that at the beach, looking out across the ocean, marveling that the water is almost never sloshing around at any scale proportional to itself. It's up to us to educate those who don't understand positive feedback loops and the existential risk they present to any system in equilibrium.)
