Forest Cover ≠ Forest Certainly a good thing: Creating ways to help farmers financially benefit by preserving forests on their lands is a vital part of combatting climate change — but (at the risk of being too snarky) I can't help but thinking that the differences in carbon storage of a particular area of land when it's an actual forest and when it's only got 10 % of its original tree cover is pretty signif

of highly - organized functioning
of ecological communities, including their genetically encoded ability to respond to environmental perturbations

forests will ease global warming) will continue to lack any resemblance to reality.
