How does global warming affect the Arctic?

definition from NASA--"an increase in the average temperature of Earth's surface" scientists think humans and ecosystems may not be able to adapt to these climate changes countries came up with an agreement called the Kyoto Protocol to help solve the problems caused by global warming--160 countries in 1997--met in Kyoto, Japan-- Pictures

 * Effects of global warming **

One of the most important is that dark open water and tundra absorb much more solar heat than white ice and snow. This is a "feedback loop" that will make changes happen faster.

The great loss of ice from the Arctic, which includes not only the polar sea ice cover but also thawing glaciers and tundra permafrost, has other major implications. One of the most important is that dark open water and tundra absorb much more solar heat than white ice and snow. This is a "feedback loop" that will make changes happen faster.

There might be deadly viruses in the melting glaciers. There was a virus, called ToMV, found by american researchers in the arctic ice, it is a warning that there may be more viruses.
