Climate change could result in a more abrupt collapse of many animal species than previously thought, starting in the next decade if greenhouse gas emissions are not reduced, according to a study published this month in Nature.
The study predicted that large swaths of ecosystems would falter in waves, creating sudden die-offs that would be catastrophic not only for wildlife, but for the humans who depend on it.
“For a long time things can seem OK and then suddenly they’re not,” said Alex L. Pigot, a scientist at University College London and one of the study’s authors. “Then, it’s too late to do anything about it because you’ve already fallen over this cliff edge.”
