Well look what's happending to the Polar Bear population. Because of rising temperatures Greenland's ice fields form later and recede earlier in the season every year. To get through the summer of fasting the bears have to really layer on the fat before the ice breaks up. So if that (breakup) gets shortened by two or three weeks, that's a lot of fat they don't get to store. These days breakup is, on average, 10 to 14 days earlier than a couple of decades ago. Not only are more cubs dying but the birth rate has dropped 15%. Temperatures in western Hudson Bay have been steadily rising 0.3 to 0.4 degrees every decade since 1950. Some researchers concluded that some Arctic areas have warmed 10 times as fast as the world as a whole, which has warmed an average of 1 degree Fahrenheit over the past century. If this continues we are in for a rude awkening! You don't have to give a name like Global Warming if that makes you feel better but this is what is occuring.
