Polar bears can be saved by emissions cuts, study says

So, even though greenhouse gas emissions put the Artic cap and the polar bear on its way to extinction, scientists are now propsing "emission cuts" to save them. These rapid cuts would help preserve ice cover. Dr Amstrup and colleagues say that the irreversible loss of the Arctic might be avoided if industrial societies act quickly to cut emissions. They claim we have not reached the "tipping point" for the Arctic. Now, they are also finding crossbreeding between grizzly bears and polar bears? Dr Kelly suggests that as the ice cap melts and polar bears go ashore, the natural barrier between the bear populations will fall, and such hybrids, dubbed "pizzly bears" by some, might become more commonplace. I honestly can't even say whether or not this is a good thing or a bad thing.
