After the #extremeHeat in France, the danger of #wildfires is enormous. #Heatwave and #soil #dryness didn't change much for the plants this week - with "cool" 30°C and full sunshine. #Trees try to resist by getting "dried" #leaves. At a certain heat temp., the process starts at the exterieur like burnings. Then the green vanishes to the centre until #photosynthesis is stopped. If the plant can't get soon enough rain to regenerate, it can die. Food crops die before trees. #oak #ClimateDiary
