Have you read something about trees in some (tropical?)
climates being less effective or maybe even having a
negative effect? Thought I saw that someplace. Don't
see how that can apply to Hawaii. It seems that trees
have a cooling effect here.

No one can deny that a lot of carbon is stored in the
wood. But if the trees also lead to higer temperatures,
then it might be counter productive.
