There is a common critical drought and temperature threshold that results in significant drought damage or death across many different ecosystems. Tree death occurs when drought and temperature conditions exceed 98 percent of the total range of conditions experienced at that particular site.[from the article]
For example, the droughts, direct human effects and their interactions “may be more immediate threats to the integrity of Amazon rainforests, and should remain a focus of conservation policy.”
