A quick vacation to Washington's Olympic Peninsula reminded me of two things. First -- dang, those trees are huge!

And second -- dang, there's a lot of clearcut coastal forestland that's still just basically sitting there: no trees, just scrub and piles of decaying stumps.
Which got me to thinking: How much CO2 could the clearcut land store if returned to its full rainforest glory? Enough to take a serious bite out of our climate-warming emissions?
