Last week, a new study in the journal Science highlighted the role forests could play in tackling climate change. Researchers estimated that by restoring forests to their maximum potential, we could cut down atmospheric carbon dioxide (CO2) by 25 percent — a move that would take us back to levels not seen in over a century. Though the study brings hope in the fight against climate change, other experts warn the solution is not that simple.
The study, led by scientists at ETH-Zürich, Switzerland, determined the planet has 0.9 billion hectares of land available to hold more trees — an area the size of the continental U.S. Converting those areas into forests would be a game-changer for climate change, the authors suggested.
