About 960 kilometers of the track is 4,000 meters above sea level, with the highest point at 5,072 meters.

He said the railway was built to allow a 2-3 Celsius degree temperature rise through measures including fixing ventilators under the railway and installing equipment producing cooling air to prevent thawing of tundra.

Dr. Howard MacCabee, an oncologist in California and a conference participant, says that even very liberal estimates show that industrial pollution by itself has negligible or little effect on global warming.

"Human contribution is small, probably not zero, and it's small compared to these other factors which we cannot change. We cannot change the sun, we cannot change [the sun's] multidecadal oscillations, we can't change ocean currents, we can't stop El Nino," MacCabee says.

Killer whales benefit from global warming: Researchers

Sea ice loss has already caused problems for polar bear populations, and it's bad news for marine mammals like belugas, narwhals and bowhead whales, which rely on ice to evade orcas.

"As they lose the ice, they're going to lose protection," Ferguson said.

Thank goodness the thickening ice saved these 629 narwhals from the alleged SUV-induced killer whale invasion

MITTIMATALIK/POND INLET - Of the 629 narwhal carcasses now sitting frozen to the sea ice near Pond Inlet, 25 will be removed and taken to the Inuit-owned lands area of Bylot Island south of Sirmilik National Park.

The carcasses are the remains of the narwhals harvested last November after they were trapped by thickening ice.
