When Deutsch and Penn ran their models to find out how species would respond in the very high- and low-emissions scenarios, they found two dramatically different visions of the planet’s future. In the very high-emissions scenario, the projected mass extinction rivals the severity of the previous “Big Five” extinctions in Earth’s past—including the Permian-Triassic extinction and the one that wiped out the dinosaurs. But if warming stays at the levels estimated in the low-emissions scenario, the loss of species due to climate change should stay close to its current levels.
“You see us effectively sitting on the good side of a cliff,”
