Impacts of global warming on Permo-Triassic terrestrial ecosystems

► Wildfires and acid rain caused devastation of land life at the end of the Permian. ► Tetrapods suffered massive losses, as severe as life in the sea. ► There were extinctions of plants and insects also, but perhaps less severe. ► Key killers for life on land were acid rain, mass wasting, and aridification. ► Hypoxia may not have been the main killer of plants, insects, and tetrapods.
