Forests offset warming more than thought: study
Replanting forests can cool the planet even more than some scientists once believed, especially in the tropics. But even if every tree lost since the mid-19th century is replanted, the total effect won’t cancel out human-generated warming.

It eventually evolved into a collaborative research paper, drawing on Earth system modeling and land-use data to explore what large-scale reforestation could realistically achieve.
