No more ice

Ocean currents move hot water from the tropics to the colder regions north and south, and bring it back cold. As the temperature of tropical seas rises, provoking stronger hurricanes, so does that of ocean currents, which means the warmth they carry gets closer to the poles.

The polar ice-caps are melting faster than predicted. This is associated with an irregular jet stream and hot air reaching polar latitudes. Rising temperatures around the equator are sending more heat to the poles. And that extra atmospheric and oceanic heat is being cooled by melting ice. When the ice is gone, that hot air and water will just get hotter and hotter.
