Increasing CO2 emissions have caused Arctic temperatures to rise by five degrees Celsius over the past 100 years, and the extent of sea ice has decreased by six percent over the past 20 years. By around 2050, scientists now predict a 60 percent loss of summer sea ice, which would more than double the summer ice free season from 60 to 150 days.

Ummm...this is bad?

Yeah, a 5 degree C increase in the tropics would be bad. But a 5 degree C rise in arctic temperature still leaves it too !@#$%%^ cold to be habitable.

I'm sorry, but here at the 45th parallel (give or take), a little warming makes for milder winters, a longer growing season, and generally better living. Let's think about humans first, polar bears second.

No, it's quite a good thing. Envirowhackos like to sit in their air conditioned offices and cubicles and try to dictate to the world that we have to freeze global ecology forever exactly where it was 300 years ago at the end of the Little Ice Age, when atmospheric carbon dioxide concentrations were at the lowest levels in geological history, and to 'restore' wetlands which are mostly artifacts of glaciation, so that hordes of disease carrying mosquitoes can proliferate. They don't really know what they're talking about and a lot of them are misanthropes, IAC.
