The article presents information on a study conducted on the impact of rising temperatures and drought on the mortality of trees. In the study, scientists Nathan L. Stephenson and Phillip van Mantgem of the U.S. Geological Survey analyzed the effects of higher temperatures on old-growth temperate forests. The researchers said that the combination of temperature and drought reduces the ability of the forests to absorb carbon dioxide, which traps heat and results in global warming.
