yep, exactly what humanity needs now to go to hell faster is less forests.
> Tundra vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens.
So, they want to replace grassland with... grassland (maybe with less shrubs)?
To remove the layer of soil is easy but to make it appear again magically... not. You need thousands of years in some cases.
More carbon in trees = good. Maybe we could have a chance.
I think that is not so difficult to understand the concept after so many decades talking about it.
Russia has a 23% of the forests in all the planet. Bigger than Amazonas.
Russian and Canadian forests are bigger than tropical forests, but they are much less productive, contain much less life and therefore much less carbon than tropical forests. That's why restoring the native grasslands (which were destroyed by humans) would be an improvement.
