It seems the redwoods in CA have been doing well with the increased CO2 and reduced fog in Northern CA if a recent study is to be believed. Go trees go. http://www.sfgate.com/science/artic...ods-in-growth-spurt-of-a-lifetime-4730759.php If you haven't been out to Northern CA, around the Avenue of the Giants, you need to put it on your bucket list. Stunning, natural, items are there. The Sequoias in Yosemite are awesome in their own right as well.
