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.
Originally, I believe, the US area was one deciduous forest all the way to the Missouri river and perhaps beyond, with feet of rich topsoil below. Slash and burn agriculture worked to clear the land and create one of the greatest agricultural areas in the world, in the future responsible for feeding lots and lots of people. Reforestation of that particular land would reduce the food supply. Of course, that precious topsoil is being lost by current agriculatural practices which will eventually need reform.
