What Will Ice-Free Arctic Summers Bring?: Scientific American

"My people rely on that ocean and we've seen some dramatic changes," said Inupiat leader Caroline Cannon at a Greenpeace event on the Arctic in New York City on September 19. "We are the gatekeepers of the ocean. We speak for the animals. They provide for us so it's our time to speak for them," by arguing to ameliorate climate change.
..."If we release that methane, we will amplify global warming by an unknown amount," Maslowski says. "We have no idea."  [If the science is so settled, why don't you have some idea?]
..."The jet stream becomes more kinked," NSIDC's Meier notes, which allows cold air to spill further south or warm air to penetrate further north.

If Greenland were to melt entirely—which is still a distant prospect according to most glaciologists' estimates—the ice sheet contains enough water to raise sea level by six meters globally. "How many people live within six meter sea level rise of the coast?" Barber asks. "The answer is: too many."   [To prepare for the CO2-induced melt of the Greenland ice cap, should we evacuate all areas that are less than six meters above current sea level?]

The seasonal loss of all "Arctic sea ice is one of those tipping points and unfortunately we're going to pass that tipping point," said climate scientist James Hansen, director of the NASA Goddard Institute for Space Studies in New York City, at the same Greenpeace event. "I think we're going to lose that sea ice. The good news is: this tipping point is reversible." Should local conditions change, for whatever reason, however, it is possible the ice could regrow.
..."At this time, the Arctic Ocean is a biological desert," notes ecologist Louis Fortier of Laval University in Quebec City. If the plankton blooms, the tiny photosynthesizers pull carbon dioxide out of the air and can serve as the bottom of a food chain that could create new and productive fisheries.

#climate change means US insurers' risk models don't work http://huff.to/Vqzbln  - so more will lack insurance. But it's natural cycle, right?
