Not enough. We both cut down trees and burned underground carbon stores.

Merely replanting trees goes part of the way but it can’t address the whole issue.

The calculations you showed seem to be about blunting annual emissions. But we still have all the excess we previously emitted which has warmed the atmosphere. We need to deal with that eventually.

The amount of trees that could be planted would capture more than the airborne excess carbon, which means they would be capturing previous excess too. Since we're really close to peak global CO2 emissions, this means the new trees would be a carbon sink that keeps capturing excess carbon for at least decades, until far better capture solutions are created than long disruptive pipelines.
