6. Reduced regional precipitation

Some scientists predict as much as a 10% decline in precipitation in the subtropics for each 1°C (1.8°F) of global warming.

7. Arctic-free summers

If the Earth warms by 2°C above pre-industrial levels (we are now 1°C warmer), scientists predict one out of 10 summers in the Arctic will be ice free. Warming in excess of 4°C will likely further eliminate Arctic ice.

8. Greenland could completely melt

Greenland’s ice sheet melt is rapidly accelerating, and further temperature increases could cause the massive ice sheet to completely melt within a few hundred years.

9. Sea level rise

Warming of 4°C will likely lead to a sea-level rise of at least 3 feet by 2100, with some estimates of the rise as high as 8.2 feet.

10. Long-term major sea level rise

In the longer-term, sea levels could rise by some as much as 50 feet.
