North America (and the US) is greener than 20 years ago.

Europe is greener than 20 years ago.

Asia is greener than 20 years ago.

Africa is greener than 20 years ago.

The entire planet is greener than 20 years ago.

It has nothing to do with people planting trees and everything to do with Co2 being what plants eat.

Fully agree. The world was greenest during the Carboniferous when avg temps were 0 above modern levels and CO2 was 800ppm.

That's my understanding as well: more carbon dioxide -> more green.
