"…they exceed expectations for even the strongest #ElNiño, if that were the only driving factor. Warming is also being driven by another factor, one that is ultimately more consequential: a large decrease of Earth’s #albedo…Earth has become darker, absorbing more of the sunlight…(Fig. 2)…is a decrease of… (reflectivity)…equivalent to a sudden increase of atmospheric CO2 from 420 to 530 ppm."
"Every year the world subsidizes fossil energy adds 12 trillion dollars to the global economy. Take that away and you are in a fine pickle. You had better find something else to spend it on, and quick.
My ace DMI colleague @Hotblack43 is sending a fancy camera up to the #ISS with #AndreasMogensen on the #Huginn mission this week + calling for people to make + post full moon snaps here in RAW or NEF format (NOT Jpeg) tagged #NewMoonSnap
It's to help measure the earth's #albedo + perhaps solve an important #climate puzzle
