God I hate the human race.... well no, thats not accurate, I hate the rediculously vain and pan in the flash media, and the ignorant population who dosent care whats going on outside their back yard.....
For all we know this could be the start of the entire artic-ice shelf collapsing, AKA the APOCALYPSE and this dosent even get 5 minutes on the nightly news.

How is this viewed elsewhere?
It is a scientific fact that we know that the planet is warming.
It is a fact that we know that pollutants cause local warming.
It is a fact that this planet is at it's highest ever level of pollution.
It is a fact that we still cannot tell the difference between short term variance and long term patterns.
It seems to be a fact that we will butt-bang this planet until we have proved it is dead.

Can an ice age end in one persons life time? |
Tough to say, the mechanisms that cause ice advances and retreats can occur in a lifetime, but the effects of those mechanisms usually take much longer to be realised. There's evidence from ~115,000 years ago of an ice advance not only starting but it's impact being felt withing a few years. Pollen from NW Europe shows vegetation changed rapidly from an "interstatial" - warming period - to a glacial period and this happened "suddenly" geologically speaking, within as few as 20 years.
At the end of the last ice advance, ~13,000 years ago, the planet had been warming for about 1,000 years but suddenly reverted back to glacial conditions in NE America and NW Europe. This was caused by a retreating ice sheet covering the Great Lakes region weakening enough for "Lake Agassiz" - a monstrous lake once located just to the NW of Lake Superior - to break through and drain down the St Lawrence pouring into the N Atlantic shutting down the "conveyor belt" system - a mechanism for transfering heat from the tropics to the poles. Of note, this conveyor system for re-distributing heat to the poles roughly follows the path of hurricanes.  This period also saw other vast glacial lakes bursting their ice dams, Lake Bonneville in Utah and Lake Missoula in Idaho and Montana, and those Siberian glacial lakes responsible for the sudden freezing of mammoths so often cited by "Great Flood" proponents...
Btw, technically speaking, we're in an ice age and have been for millions of years. While there may be evidence from long ago of ice ages, several theories have been advanced to explain the one we're in. The rise of the Himalayas ~40 million years ago changing the jet stream, the closing off of the Panama Isthmus shutting down the transfer of tropical and equatorial waters between the Pacific and Atlantic, etc.
I seriously doubt "warming" in Antactica caused the ice shelf's collapse and I'd love to see the evidence. Ice shelfs can only grow so larger before they break off and that is a natural cycle, not something induced by man.

Che is correct. We are in the middle of an ice age, enjoying a few sunny millenium. That is a fact, according to the ice cores reamed out of the very deepest ancient pack ice, according to past ice ages. If this ice age is anything like prior ones, get some good thermals.
So, when you drive your car you are in fact preserving the world as we know it, and perhaps delaying the next inevitable 'snowball earth' scn.
Do a search for 'snowball earth'. I dare you.
