• Insects may migrate in strange new directions. For example, as a temperate climate moves north in the United States, pine beetles could kill off the great whitebark forests.
• Greenland’s glaciers continue melting at a faster rate. In fact, Greenland’s Jakobshavn Glacier is already the fastest-moving ice field on the planet; the amount of ice breaking off the glacier every few days contains enough water to supply New York City for one year.
• Because of a decrease in sea ice, polar bears make the endangered species list.
• Forests begin to take root in Canada’s melting tundra.
• The Pacific islands of Tuvalu could sink beneath the rising ocean tides.
• At 2°C of warming, the impact on the marine ecosystem is likely to be severe, and it is possible that the vast majority of the world’s tropical coral reefs will die off.
