Arctic Tipping Point?

Scientists are suggesting that the Arctic thaw may have reached its tipping point and that Arctic ice may disappear in the summer, decades before it was anticipated to happen.

They caution that that this is not alarmist, as tipping points can be reversed but they do say that many models have underestimated the speed of which Arctic ice is melting.

Scientists ‘stunned’ as Arctic sea ice shrinks to 30-year low

Arctic ice has melted to its lowest recorded level, with scientists and researchers blaming rising concentrations of greenhouse gases, which have pushed up temperatures from one to four degrees.

Canada's typical summer heats up, especially in the Arctic

The summer of 2007 was hotter than average and that’s becoming the norm. Canada’s statistical agency says the trend is “consistent with what scientists predict will happen more frequently as the world becomes warmer as a result of climate change.”

The News Just Gets Harder to Bear

Two-thirds of the world's polar bears will be killed off by 2050 — and the entire population gone from Alaska — because of thinning sea ice from global warming in the Arctic, government scientists forecast Friday. Polar bears have walked the planet for at least 40,000 years.

Rapid climate change threatens world’s largest creatures

A new report entitled “Whales in hot water?” says whales, dolphins and porpoises (cetaceans) face increasing threats from global warming as rising sea temperatures destroy polar habitats and undermine their food sources.

Global warming heats up in the Arctic

The U.S. Geological Survey estimates the Arctic holds some 25 per cent of the world’s undiscovered oil and gas, among other resources, and the melting of the Polar ice cap due to human-induced climate change is accelerating the stampede for riches. It's a catastrophic scenario for the Arctic ecosystem, for polar bears and other wildlife, and for Inuit populations whose ancient cultures depend on frozen waters.

U.S. stifles officials from responding to global warming questions

Internal memorandums circulated in Alaska’s federal Fish and Wildlife Service appear to muzzle government biologists traveling abroad in Arctic countries from discussing climate change, polar bears or sea ice without official authorization. Only those who “understand the administration’s position” can talk to the issues.

Asia’s pollution hits global climate harder than previously realized, study finds

Scientists say an “Asian haze” of pollution from rapid industrialization is boosting storms in the Pacific and having profound impacts that may be felt as far away as the Arctic.

UN draft: Climate-change impact worse than expected

An unpublished draft of the long-awaited second part of a United Nations report , obtained by SPIEGEL ONLINE, says global warming is happening faster than previously believed. No region of the planet will be spared, says the UN’s Intergovernmental Panel on Climate Change, and some will be especially hard-hit.

$350-million study of North, South polar changes set

Scientists from 60 countries will camp on drifting Arctic sea ice and trek to uncharted Antarctic mountains to clarify the role of greenhouse gases and global warming in the rapid changes already occurring at both poles. Called the International Polar Year despite its two-year timetable, it is the fourth such integrated Arctic and Antarctic science effort since 1881. The last ended in 1958.
