I think issue is desertification, and spikes in temperatures causing plants to get into state of shock. Some tree species are very susceptible to temperature change, so they can suddenly die. Also, trees except being CO2 deposits are huge deposits of water, so tree evaporation draws more rain, and there is entire feedback cycle of water, so it is not simple as "more heat more rain as 2/3 of planet is water", as by same logic in deserts would be rain all the time. It is interesting how clouds form as well, as they need small particles, basically seeds to form...
