Trees can’t save us

The birth and growth of small-town forests has occurred all across America, aided by our love of shade and having adequate water. The rise of surface level CO2 also has given them a boost, at least up to a point. Rising temperatures, drought and nitrogen depletion in the soil are threatening factors in their future health, and there is no way we can plant enough trees to overcome our outpouring of CO2.
