A soil-plant-atmosphere model for 2050-2069 predicts that changes in precipitation and air temperature are likely to lead to increased plant mortality risk within 13 temperate and tropical forest biomes across the globe; however, increases in specific humidity and carbon dioxide concentrations are likely to partially offset the rising mortality risk, according to a study.
