Arctic Has Lost Enough Ice to Cover Texas

Although this wasn’t the worst winter on record for retention of Arctic sea ice, a report from NASA and the National Snow and Ice Data Center says that the region is now missing a Texas-sized chunk of the stuff that keeps polar bears alive and cities above sea level. More alarming, the ice that is there is younger, thinner and more fragile than in years past.

Polar Bears ‘Threatened’

The plight of the polar bear has come to represent the real-world impact of the climate crisis, so it is only fitting that the Bush administration had to be ordered by a court to make a decision on the endangered status of the species. After years of delay, the Interior Department finally classified the animal as threatened, but also promised to fight any meaningful protection.

UK Joins Grab for Polar Territories

While Russia is leading the race to claim the North Pole for itself, Britain has decided to expand its territory on the other end of the world, in Antarctica. The British Foreign Office says it has no immediate plans for the additional 1,000 square miles of seabed, but simply wishes to “safeguard for the future.”

Arctic Land Grab Update: Russia Claims Victory

Russian officials say they have proof to back up Moscow’s claim to the north pole—and nearly half a million square miles of neutral Arctic territory—but don’t expect Denmark, Canada and the U.S. to go down without a fight. It’s all part of a nakedly opportunistic attempt to cash in on energy resources made available by global warming and melting ice caps.

Not So Fast, Putin

For years the North Pole has been considered international territory, and that seemed to suit everyone just fine until global warming came along, making it theoretically easier to extract oil and gas from the region. The Russians kicked off the land grab by planting an underwater flag, and now Denmark is launching a similar expedition. Canada, Norway and the U.S. also have territory disputes in the Arctic.

Russia Claims Much of Arctic

Russia is launching an underwater expedition to the North Pole in order to back up its claim to a massive section of the Arctic, which may contain vast energy reserves. “The Arctic is ours and we should demonstrate our presence,” said a Russian parliamentarian and explorer who will participate in the flag-planting expedition.
