High CO2 Reduces Tree Water Loss

Many climate scientists expect a hotter world will be drier in many regions. Tough on plant growth. However, higher atmospheric carbon dioxide reduces the need for trees to open pores to absorb carbon dioxide. This reduces water loss from leaves. DURHAM, NH, July 10, 2013 - A study by scientists with the U.S. Forest Service, Harvard University and partners suggests that trees are responding to higher atmospheric carbon dioxide levels by becoming more efficient at using water. Whether this will be a benefit to you personally probably depends on where you live. Trees that release less water into the atmosphere will reduce precipitation downwind. How efficient trees are in using water has implications for ecosystem function, services and feedbacks to...
