It is well documented than more CO2 directly benefits plant growth. See Climate Change Reconsidered: The Report of the Nongovernmental International Panel on Climate Change (NIPCC) 2009 - Chapter 7 examines the biological effects of rising CO2 concentrations and warmer temperatures. This is the largely unreported side of the global warming debate, perhaps because it is unequivocally good news. Rising CO2 levels increase plant growth and make plants more resistant to drought and pests. It is a boon to the world s forests and prairies, as well as to farmers and ranchers and the growing populations of the developing world. Chapter 8 examines the IPCC s claim that CO2-induced increases in air temperature will cause unprecedented plant and animal extinctions, both on land and in the world s oceans. We find there little real-world evidence in support of such claims and an abundance of counter evidence that suggests ecosystem biodiversity will increase in a warmer and CO2-enriched world.
