Other communities may not need to pull up stakes for decades. But Cuban social scientists are already fanning out to those ill-fated villages to educate people on climate change and win them over on the eventual need to move. That’s an easier sell in the wake of a major hurricane, Rodríguez Batista says. “Irma has helped us with public awareness,” he says. “People understand that climate change is happening now.”

Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time.

Sea ice data updated daily with one-day lag.

A blue ocean event means a complete absence of Arctic sea ice, allowing the heat of the sun to fully penetrate the open waters of the Arctic, which would then dramatically accelerate the rate of warming in the Arctic.

Some countries fared better than others: tropical areas such as Central and South America were hit badly, but crop yields actually increased in certain temperate areas, including northern China and the United States. Some areas of those countries saw yield increases of up to 90% — but this was not enough to offset the global decrease.
