Evidence is presented that indicates US temperatures decreased by a fraction of a degree during the past 70 years contrary to the estimates of some researchers concerned with the greenhouse effect. There is general agreement that the carbon dioxide concentrations in the atmosphere will double by the late or mid 21st century. Experiments on cotton growth under increased temperature and carbon dioxide concentrations indicate sizeable gains in yield. This increased yield is exhibited by citrus trees and is projected for other crops. There is a concomitant need for more water and fertilizer. Increased populations of parasitic mites and insects also occur. Climatic changes are seen as being more gradual than previously thought. The possible increases in food production under these changes in climate are one positive element in the emerging scenario.
