The most important graph in the world! Another month of NASA CERES data shows that our planet keeps getting darker as global air pollution, cloud cover and ice area continue to decrease. A warmer planet radiates more heat to space, but our greenhouse gases now keep >4 W/m² in!

4W/m2? with Eartht surface of 510 Million km2 that adds up to 2040 Terra Watt 🤯... correct?

Yes (but it's written terawatt). So about 2 petawatt (PW, 10¹⁵ joules per second). The AMOC transports about 1 PW of heat northward, comparable to the greenhouse gas forcing over the Northern Hemisphere.

tx Leon. I'll update my "how many Hiroshima-bombs worth of energy are added to our planet"... 😢
