In summary, there is high confidence that ET increased by between approximately 0.5 and 1.5 mm yr2 between the 1980s and early 2010s due to warming-induced increased atmospheric demand worldwide and greening of vegetation in many regions. Increases in many areas are 10 mm yr-2 or more, but in some tropical land areas, ET has decreased by 10 mm yr-2. Plant stomatal responses to rising CO2 concentrations may play a role, but there is low confidence in quantifying this. Changes in land cover and irrigation have also changed regional ET .
