"You can stop the climate disaster. Trees will save us" – we wrote in early July quoting the publication in "Science". The researchers then estimated that if we could forests 0.9 billion hectares – an area roughly equal to the US surface – new forests would draw 205 billion tons of coal from the atmosphere.
Of course, not directly, the forest matures for hundreds of years. But if we quickly reduce current greenhouse gas emissions to zero and stop cutting down natural forests like Amazonia, it would be possible within ten human generations to remove less than half of the carbon we have emitted – mainly in the form of CO2 – for the past two and a half centuries.
