Due to human activities. the level of CO2 and other trace gases in the atmosphere has increased. These changes in atmospheric composition will result in increase in global temperature. The best estimates for the southern U.S. (30oN to 35oN latitude) are an annual increase of about 1.5 to 3.0oC by the year 2050. This predicted change has important implications for forest insect pest management and silviculture. Implications of direct and indirect effects of changing climate on fores insects are discussed. A specific example illustrating the effect of climate change on losses from southern pine beetle attack is presented.
