Fear of excessive warming from more CO2 in the atmosphere, including that released from human activity, has caused some people to advocate substantial and expensive reductions in CO2 emissions. But observations, such as those on our CO2 Coalition website, show that increased CO2 levels over the next century will cause modest and beneficial warming—perhaps as much as one degree Celsius (1.8 degrees Fahrenheit)—and that this will be an even larger benefit to agriculture than it is now. The costs of emissions regulations, which will be paid by everyone, will be punishingly high and will provide no benefits to most people anywhere in the world.” — Harrison H. Schmitt and Rodney W.
