Cruising the high arctic. As you get further towards the top of the world, the curvature of the earth gets more pronounced. The icebreaker was having no problems, as the ice was breaking up, and is continuing to do so year on year. This is causing big problems, however, for polar bears, as there are fewer floes that will support their weight without tipping. Polar bears are excellent swimmers, but in recent years more and more are becoming exhausted and drowning as a result of being unable to haul out.

GLOBAL WARMING 2

GLOBAL WARMING- THE EVIDENCE
Believe what you hear....this shot was taken in Svalbard. The captain gingerly edged the ship right up to the ice shelf until it was actually nudging it, enabling the hardier amongst us to take a , shall we say, bracing shower in the run-off caused by the melting ice. It's not until you see the sheer volume of meltwater that's running off 24/7, that you can start to get an idea of just how global warming is affecting the arctic and antarctic. This run off is just one of dozens along a single ice shelf, this shelf being a relatively small one at, I would estimate, about a couple of miles long and maybe 50m high. Of course, it won't be that size any more....
