How will the terrestrial vegetation of South America respond to global warming and atmospheric CO2 enrichment? Climate alarmists suggest there will be widespread declines in both ecosystem size and productivity. But are these predictions correct? Given the fact that over the past century the Earth has experienced what alarmists refer to as unprecedented rises in both atmospheric temperature and CO2 concentration relative to the past two thousand years and several million years, respectively, plants should already be responding to the changes in these two environmental parameters. And what has that response been? In this summary we consider this question as it applies to locations in South America.
