The link listed at bottom of the page, is to a new climate change study that has some very interesting results. I will let you read it for yourself but there are a couple of quotes that are challenging to current thought.
"Apparently, these natural carbon sinks [forests] only do their job effectively in tropical regions; in other areas, they have either no impact or actually contribute to warming the planet".
"You can't just blindly go ahead and reforest and that will tackle climate change," he says, pointing out a key finding in the study. "If you think about conservation groups, they're all talking about planting trees. We should be protecting trees for other reasons."
Does this report undermine some of our assumptions on tree planting?
