By Don Comis, ARS Rising carbon dioxide (CO2) levels can reverse the drying effects of predicted higher temperatures on semi-arid rangelands, according to a study published Aug 3 in the scientific journal Nature by a team of U.S. Department of Agriculture (USDA) and university scientists. Warmer temperatures increase water loss to the atmosphere, leading to drier soils. In contrast, higher CO2 levels cause leaf stomatal pores to partly close, lessening the amount of water vapor that escapes...
