Global warming has caused big problems for polar bears, which depend on sea ice for access to the ocean so they can hunt seals and other prey.

Before the melt, when they were hunting on stable sea ice, the polar bears had a big advantage over their favoured prey.

There is rising concern among polar bear biologists that the big recent summertime retreats of sea ice in the Arctic are already harming some populations of these seal - hunting predators.

What most people seem to forget here, is that on one hand there are fundamental thermodynamical arguments which demand that hurricane intensity increase over time, while on the other hand, there are these two big chunks of ice sitting in both polar regions, which will counteract the warming process in their own special way.

Imagine being that polar bear, having endured a life - threatening swim created by ever - distant ice floes created by our global warming, only to finally find a nice big chunk of ice where he could finally go fishing, only to confront and be murdered by enemy no. 1: mankind, in this case Icelanders.

(Keep in mind that almost all Arctic sea ice researchers add a big caveat when talking of an «ice - free Arctic Ocean,» noting that a big region of thick floes north and west of Greenland will almost surely persist in summers through this century, which is one reason some scientists have proposed targeting polar bear conservation efforts there.)

It was the warming of the polar ice caps that became the greatest concern, since this was the first tangible evidence, and will have the biggest initial impact upon coastal cities and low lying countries.

If you'll recall from my previous post, polar bears seem to have barely survived the extensive sea ice coverage during the Last Glacial Maximum — in other words, too much ice (even over the short term) is their biggest threat.

A team of international scientists is due to set off for the world's biggest iceberg, fighting huge waves and the encroaching Antarctic winter, in a mission aiming to answer fundamental questions about the impact of climate change in the polar regions.The scientists, led by the British Antarctic Survey (BAS), are trying to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf on the Antarctic peninsula.In July last year, part of the Larsen C ice shelf calved away, forming a huge iceberg - A68 - which is four times bigger than London, and revealing life beneath for the first time.

Not only that, but if rising CO2 levels were responsible for the decline of sea ice and implied effects on polar bears since 1979 (when CO2 levels were around 340 ppm), why has spring ice extent been so variable since 1989 (when the first big decline occurred) but so little changed overall since then?

The Polar bears stubbornly refuse to go extinct, indeed the buggers are thriving, the glaciers don't appear to be disappearing, sea levels have stayed boringly level, we haven't been subsumed by hordes of desperate climate refugees, the polar ice caps haven't melted, the Great Barrier Reef is still with us, we haven't fought any resource wars, oil hasn't run out, the seas insist on not getting acidic, the rainforest is still around, islands have not sunk under the sea, the ozone holes haven't got bigger, the world hasn't entered a new ice age, acid rain appears to have fallen somewhere that can't quite be located, the Gulf Stream hasn't stopped, extreme weather events have been embarrassingly sparse in recent years and guess what?

«If climate change is an elaborate hoax, then the ice sheets must be in on it; the sea level must be in on it; and the polar bears are likely in on it, although they are big losers.»

Some bad news for migrating seabirds: shrinking Arctic ice has left polar bears scrambling to find food, and they've taken to eggs in a big way.
