Polar Vortex: Yes, it's global warming!

The much-hyped "Polar Vortex" that plunged much of North America into dangerously low temperatures is giving the climate change denialist crowd an opportunity to gloat—and, typically, display their ignorance. Bloomberg on Jan. 7 presented a sneering Tweet from Donald Trump dismissing global warming as "bullshit" because the "planet is freezing." But the Bloomberg account, as well as a video on the Greenpeace Blog, quotes Rutgers University climate researcher Jennifer Francis explaining how the Vortex was likely unleashed by—yup, global warming! It seems that the Jet Stream, which normally serves as a boundary separating cold air to the north from warm air to the south, is being destabilized; receding arctic sea ice lessens the temperature difference either side of the Stream, thereby slowing its velocity and causing large loops and meanders to form, and even for it to get "stuck." When this happens, North America and Europe are going either into extreme heat or extreme cold, depending on where the jet gets jammed. Recent record-breaking highs in Chicago and Fairbanks, as well as shriveling heat waves across the Great Plains, may have been caused by the same phenomenon now sending the mercury plunging in the Midwest and Northeast.

Sweden: Sámi protest British mining company

Swedish police have repeatedly broken up a protest occupation by Sámi indigenous people against iron mining in a crucial reindeer herding area above the Arctic Circle. Two weeks ago, police had to dig protesters out of the ground after they buried themselves to the neck in order to shut down a road. Jokkmokk Iron Mines, subsidiary of UK-based Beowulf Mining, runs the Kallak (Gállok) site, on lands ostensibly coming under Sámi autonomous rule. Sametinget, the nascent Sámi general assembly, has issued a demand to halt all mining on Sámi lands without prior consultation. But the Swedish government does not recognize Sámi indigenous title. "The Sámi have no power to stop people coming here to exploit the land without giving anything back, not just to the local community, but also to the Swedish state," said Josefina Lundgren Skerk, chair of the Sametinget youth council.

Arctic Great Game in Alaska missile deployment?

The Pentagon announced plans March 15 to add 14 missile interceptors to its anti-missile system in response to recent nuclear posturing of North Korea. The new interceptors would augment 26 already deployed at Ft. Greely, Alaska, with four others deployed at Vandenberg Air Force Base in California. But the system is plagued with technical failures. The last successful hit against a target was in December 2008; test launches have failed to hit their targets since then. The Pentagon is said to have discovered a flaw in the guidance system of the newest Raytheon-made model. (LAT, March 16; Bloomberg, March 15) The ABM Treaty, which barred anti-ballistic missile systems during the Cold War, was pronounced effectively dead in the Bush years

Court upholds statutory protection for polar bears

The US Court of Appeals for the District of Columbia Circuit on Feb. 1 upheld the listing of polar bears as a "threatened" species under the Endangered Species Act (ESA). Designation of the animal as threatened gives polar bears the lower of two levels of protection. This designation was challenged by both environmental groups, which argued that the polar bears should be considered endangered and be given the highest level of protections, and industry and sporting groups, which argued that they should not be protected under the act at all. The court determined that the Fish and Wildlife Service (FWS) used "reasoned decisionmaking" in deciding to list polar bears as threatened, and therefore did not disturb its designation. The agency went through a three-year rulemaking process and determined that, due to the effects of global warming, polar bears are likely to become an endangered species in the foreseeable future, warranting their designation as threatened.

Arctic sea ice cover hits record low

Arctic sea ice cover this month fell to the lowest summer minimum extent since satellite records began in 1979, according to the National Snow and Ice Data Center (NSIDC). "We are now in uncharted territory," said NSIDC director Mark Serreze. "While we've long known that as the planet warms up, changes would be seen first and be most pronounced in the Arctic, few of us were prepared for how rapidly the changes would actually occur."

Ninth Circuit dismisses Alaska village claim over greenhouse emissions

The US Court of Appeals for the Ninth Circuit affirmed on Sept. 21 the dismissal of the Alaskan village of Kivalina's nuisance claims against energy companies for greenhouse emissions it claimed contributed to global warming and threatened its existence. Kivalina brought suit against 22 energy corporations, attributing the destruction of its land to the effects of global warming, which it alleged partially results from emissions of greenhouse gases by the defendants. The US District Court for the Northern District of California had dismissed the claim on standing in 2009, stating that because it was a political question the courts could not intervene. Citing to the Supreme Court's ruling in American Electric Power Co. v. Connecticut, the Ninth Circuit ruled that:

Petro-oligarchs play presidential candidates —again

We don't doubt that Big Oil has its money on the Republicans and Mitt Romney when push comes to shove. But we noted back in 2008 that the reigning petro-oligarchs were deftly playing both sides in the presidential race. The nature of the game is that no matter who gets in, the petro-oligarchs win. But a part of the game is that Romney gets to bait Obama as a Green Stalin for suggesting that some remnants of federal oversight over the oil industry be retained—which only causes Obama to capitulate yet further. In terms of actual policy on oil and energy, the difference between the two parties has been narrowing almost from the moment Obama took office, until today it is vanishingly small. From AP, Aug. 23:
