New Study Shows Planting Trees May Not Be as Good for the Climate as Previously Believed

The climate benefits of trees storing carbon dioxide is partially offset by dark forests’ absorption of more heat from the sun, and compounds they release that slow the destruction of methane in the atmosphere, the research shows.

How phantom forests are used for greenwashing

Capturing carbon by increasing forest cover has become central to the fight against climate change. But there's a problem. Sometimes these forests exist on paper only - because promises have not been kept, or because planted trees have died or even been harvested.
