Planting more forest in, say, Canada, can actually be a source of global warming - see http://en.wikipedia.org/wiki/Carbon_offset and scroll down to "Climate impacts"
That assertion is a lot of crap. The whole article seems to be suffused with anti-environmentalist nonsense.
I am certain that returning Canada, the U.S. and other temperate areas to their original forestation would sequester gigantic amounts of CO2 and help reverse global warming.
