Study: Melting sea ice could help cool the planet by flooding the atmosphere with particles that deflect sunlight. - The study wa published by the American Meteorological Society. Australian research suggests climate modelers have underestimated a natural “thermostat” that helps alleviate the rise in temperatures: immense quantities of reflective compounds, emitted by marine microbes, that act like a handbrake on global warming.
'The simple truth: the models that predicted catastrophe for polar bears due to diminished summer sea ice turned out to be wrong.'
Polar Bear expert Dr. Susan Crockford: "What is causing the death of the polar bear as a climate change icon? Fat bears are part of it, but mostly it’s the fact that polar bear numbers haven’t declined as predicted. Not only have we been seeing pictures of fat bears rather than starving bears in recent years but there are lots of them, in Western Hudson Bay and other seasonal sea ice regions where there should be none (if the models had been correct). No wonder polar bears are falling out of favor as an icon for catastrophic human-caused global warming."
UK Times: "Scientists said satellite images suggested the North Pole would remain inaccessible except by an icebreaker...Scientists warned, though, that despite the rapid melting of the ice there was unlikely to be access to the North Pole via open water for some years. Professor Mark Serreze, director of America’s National Snow and Ice Data Centre, said the North Pole was still surrounded by nearly 800 miles of solid pack ice as of last week."
Update Aug. 15, 2017: This appears to be a media stunt to sail the Arctic ocean with the media hook of possibly sailing "even to the North Pole." The leader of the crew has said: “The secondary objective is to sail as far north as the sea ice safely allows us, possibly even to the North Pole.” BBC reports the ship has set sail on its mission of heading toward the North Pole which current data says is not possible to cross in this sail boat.
