GLOBAL WARMING ISSU NOW 2013. Arctic Climate Change... be careful man in the world today !!!!!!

The Arctic Ocean's sea ice is in a "death spiral" due to rising temperatures, scientists said in 2008. Many marine species, such as these narwhals swimming through a bay in Nunavut, Canada, depend on the ice throughout their life cycles. Experts predict that summer Arctic ice may completely disappear within a few decades.

Fact Polar bears—like this one leaping between ice floes in Svalbard, Norway's Hinlopen Strait—live on the Arctic ice, hunting seals and other fatty marine mammals. But as the ice vanishes, some experts predict this predator will also disappear from the Arctic by 2050.

NASA Permafrost—the frozen soil that forms the backbone of the Arctic tundra—is melting due to climbing global temperatures. In Alaska, the mercury may rise by 1 to 5 degrees Celsius (1.8 to 9 degrees Fahrenheit) by 2100. In this false-color image of Alaska's North Slope, taken by NASA's Terra satellite, the blue-black color shows the many ponds of meltwater that collected on the coast in July 2007.
