Under extreme heat and drought, trees hardly benefit from an increased CO2 level

  • Due to greenhouse gas-induced climate change, trees are increasingly exposed to extreme drought and heat.
  • Together with scientists of Ludwig-Maximilians-Universität München, the University of Vienna, and Weizmann Institute of Science in Rechovot/Israel, KIT researchers studied the impact of an increased CO2 concentration on carbon metabolism and water use efficiency of Aleppo pines (pinus halepensis) under drought and heat.
  • The findings of the study: An increased CO2 concentration reduced water loss of the trees and increased their water use efficiency under increasing heat load.
