A. Swimming.
1. Polar bears are strong swimmers; they swim across bays or wide leads without hesitation. They can swim for several hours at a time over long distances. They've been tracked swimming continuously for 100 km (62 mi.) (Stirling, 1988).
2. A polar bear's front paws propel them through the water dog-paddle style. The hind feet and legs are held flat and are used as rudders.
3. A thick layer of blubber (fat), up to 11 cm (4.3 in.) thick, keeps the polar bear warm while swimming in cold water (Stirling, 1988).
4. Polar bears can obtain a swimming speed of 10 kph (6.2 mph) (Stirling, 1988).
5. The hair of a polar bear easily shakes free of water and any ice that may form after swimming.
6. A polar bear's nostrils close when under water.
Now shut the fuck up about your poor bears lost floating on an ice sheet... jesus jumped up and knocked granny out of the rocking chair... |

Reports this week claimed that polar bears were being forced by climate change into cannibalism and attempting suicidal swims. Experts say it is too early to be sure, but that these are the kind of impacts expected as melting sea ice leaves the bears with longer distances to travel.
At the sixteenth biennial conference on the biology of sea mammals in San Diego, California, last week, marine biologists from the US Minerals Management Service reported finding four bears drowned off the northern coast of Alaska last autumn. They also spotted an unusually large number of bears swimming in the open sea, some as far as 95 kilometres offshore. Twenty percent of bears seen in the area in September were in the water, while records from previous years show that 4% of sighted bears were swimming.
Tonje Folkestad, climate-change officer at the World Wildlife Fund's Arctic programme in Oslo, Norway, agrees that bears are at risk from melting ice, but says it's too early to conclude that more are drowning because of climate change.
"We can't say at the moment that there is a trend for polar bears to drown," she says. "But we do expect to see more of this kind of event in the future." Spending more time in the open sea increases bears' exposure to the risks of the effect of cold, exhaustion or rough seas. "Common sense tells you that if they have to swim 60 miles instead of 20, drowning is more likely," adds Folkestad.

maybe they are fucking stupid and it takes them weeks to figure out they are floating out to sea.
maybe we are fucking stupid too and it will take us years and years of CO2 build up and temp rises to see we drifting away too.
