How to remove 200 megatons of carbon from our atmosphere
A recently published article on Science (July 5, 2019 Vol. 365 Issue 6448 pp. 76-79) by Jean-Francois Bastin et al, notes that restoration of forests is among the most effective carbon draw-down strategies humanity can implement globally. The article states that worldwide, excluding existing forests and agricultural and urban areas, our planet has room for an additional 0.9 billion hectares of canopy cover (9 million square kilometers or 3.5 million square miles). This could store 205 Gt of carbon (205 billion metric tons) representing about 25% of the current atmospheric carbon pool. The authors state that the time to act is now as climate change could shrink the potential canopy cover by 223 million hectares by 2050.
