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 preindustrial levels (we are now 1 C warmer), scientists predict that 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 ice sheet could completely melt

Greenland’s ice sheet is melting much faster than previously thought, 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 lead to a sea level rise of between 6.9 and 10.8 meters, or between 22.6 and 35.4 feet.

10. Long-term major sea level rise

In the longer-term, sea levels could rise by as much as 50 feet. In addition to the significant and inevitable changes to the climate and virtually all of the Earth’s biomes, sea level rise necessarily means less livable land area for humans.
