"Nearly three in four of us will face extreme weather changes within the next two decades, a new study predicts.

“In the best case, we calculate that rapid changes will affect 1.5 billion people,” says physicist Bjørn Samset from the Center for International Climate Research (CICERO) in Norway.

This lower estimate would only be reached by dramatically reducing greenhouse gas emissions – something that is yet to occur.

Otherwise, CICERO climate scientist Carley Iles and colleagues’ modeling finds that if we continue on our current course, these dangerous changes will hit 70 percent of Earth’s human population.

Their modeling also suggests that much of what’s to come is already locked in.

“The only way to deal with this is to prepare for a situation with a much higher likelihood of unprecedented extreme events, already in the next one to two decades,” explains Samset.

We’ve already lived through examples of these extremes…"
