Grist notes a Dec. 12 report on Nature:

Cold temperatures have kept crabs out of Antarctic seas for 30 million years. But warm water from the ocean depths is now intruding onto the continental shelf, and seems to be changing the delicate ecological balance. An analysis by [marine ecologist Craig] Smith and his colleagues suggests that 1.5 million crabs already inhabit Palmer Deep, [a] sea-floor valley… And native organisms have few ways of defending themselves. "There are no hard-shell-crushing predators in Antarctica," says Smith. "When these come in they’re going to wipe out a whole bunch of endemic species."

The US National Intelligence Council (NIC) has issued a new report, "Global Trends 2030: Potential Worlds," that emphasizes the rise of China and the risk of catastrophic climate change. An Associated Press summary Dec. 10 says the report finds global terrorism will recede along with the US military footprint in Iraq and Afghanistan, but cyber-attacks will be a growing concern. "The spectacular rise of Asian economies is dramatically altering...US influence," said NIC chairman Christopher Kojm. While the report sees the potential for US-China cooperation on global security, it also warns of resource struggles leading to instability. Under the heading "Stalled Engines," in the "most plausible worst-case scenario, the risks of interstate conflict increase," the report said. "The US draws inward and globalization stalls." The section "Black Swans" foresees extraordinary events that can change the course of history—such as a severe pandemic that could kill millions in a matter of months, or more rapid climate change. The report is optimistic, however, on the prospects for US energy independence. "With shale gas, the US will have sufficient natural gas to meet domestic needs and generate potential global exports for decades to come," it predicts.

Japan scrambled  fighter jets on Dec. 13 after a Chinese maritime aircraft entered airspace over the disputed islands known as the Senkaku to the Japanese and the Diaoyu to China. The Japanese defense ministry said the incident was the first violation of Japanese airspace by a Chinese official aircraft since 1958. "It is extremely deplorable," said Osamua Fujimura, Japan’s chief government spokesman. Kyodo News quoted Japan's Chief Cabinet Secretary Osamu Fujimura that the plane belonging to the Chinese Oceanic Administration was spotted near the Uotsuri Island at 11:06 AM local time, and Japan's Air Self-Defense Force responded by dispatching F-15 jets. The response was of course prosted by Beijing. Foreign Ministry spokesman Hong Lei  said: "Flying a marine surveillance airplane in airspace above the Diaoyu Islands is completely normal. China urges Japan to stop illegal actions in the waters and airspace of the Diaoyu Islands. The Diaoyu islands and affiliated islands are part of China's inherent territory. The Chinese side calls on Japan to halt all entries into water and airspace around the islands." (Japan Today, FT,  BBC News, Dec. 13)

Police in Sechuan's Aba county on Dec. 11 detained two Tibetan men—a monk at the local Kirti monastery and his nephew—on charges of "inciting" self-immolations. Four days earlier, the self-immolation of a 17-year-old girl at Rebkong monastery town in Qinghai brought the total number of such cases to 95. Chinese authorities again accused the Dalai Lama of encouraging the practice. (The Hindu, Dec. 11) The following day, the New York Times ran an op-ed, "Tibet is Burning," by prominent human rights lawyer Xu Zhiyong, who has defended peasants struggling to keep their lands before China's onslaught of "development."  Xu writes about his journey in October to pay respects to the family of Nangdrol, an 18-year-old self-immolation martyr. Paraphrasing the note left by Nangdrol, Xu calls the current situation in Tibet "scarless torture." He writes about his fellow passengers on his ride in a car packed with locals to Nangdrol's hometown of Barma in northeast Tibet:

In the recent wave of anti-Japan protests in China, we've wondered how much of it was genuinely spontaneous and how much (contrary to official appearances) state-instrumented. The signals are even harder to read in Vietnam, where several were actually arrested in anti-China protests Dec. 8. At issue is the contested South China Sea and its oilfields, a question that has (paradoxically, for those who can remember back just to the 1960s) caused Vietnam to tilt to the US in the New Cold War with China. Has the regime's anti-China propaganda (and exploitation of hopes for an oil bonanza to lift the nation out of poverty) created something now a little out of control? Or are even the arrests part of a choreographed game?

We were pleased as punch last month when South Korean rapper PSY's irresistible "Gangnam Style" video became the most-viewed clip of all time on YouTube, with 806 million views, surpassing something by that pisher Justin Bieber. (LAT, Nov. 24) How can this be anything other than an advance for humanity? The young YouTube star XiaoRishu, a London vlogger of Chinese-Vietnamese background, has a devastating video taking down the stateside xenophobic backlash to K-pop's ascendence, as exemplified in another vid from some redneck punk somewhere in the US heartland sputtering (all too literally) a racist anti-Gangnam Style rant (no, we're not gonna give him a link). What makes it even better is that "Gangnam Style," as its Wikipedia page informs us, is intended to poke fun at the well-heeled residents of Seoul's upscale Gangnam suburb—the song is a proletarian statement against the bourgeoisie, even if the video's legions of fans in places like Bel Air or Roslyn, Long Island, don't have a clue about this. So it is no surprise that "Gangnam Style" has now officially entered the USA's tiresome and interminable culture wars...

The Guardian on Dec. 7 noted a Dec. 3 story in Military Times, "Some Afghan kids aren’t bystanders," concerning an October air-strike in Nawa district of Afghanistan's Helmand province in which three children were killed, and, apparently, intentionally targetted—two boys and one girl, aged 8 to 12. Local officials protested the targetting of children. Writing from Helmand's Camp Leatherneck, Military Times responds: "But a Marine official here raised questions about whether the children were 'innocent.' Before calling for the M142 High Mobility Artillery Rocket System mission in mid-October, Marines observed the children digging a hole in a dirt road in Nawa district, the official said, and the Taliban may have recruited the children to carry out the mission." The supposed hole was intended for an improvised explosive device, according to the Marine official. On Oct. 16 the New York Times reported that the young victims' families said they had been sent to gather dung for fuel. Military Times isn't impressed, noting hundreds of cases in which kids were apparently used on missions by the Taliban—including one in Kandahar's Zharay district, where two boys, 9 and 11, along with a 18-year-old male, were found carrying soda bottles "full of enough potassium chlorate to kill coalition forces on a foot patrol."

The Obama administration is suddely making much of Assad's supposed preparations for a chemical weapons attack on Syria's opposition strongholds. Conspiranoid blogs, including one with the unappetizing name Sic Semper Tyrannis, assert that the supposed intelligence is coming from neocon groups like the Washington Institute for Near East Policy (WINEP) which is in turn getting the claims entirely from Syrian insurgent sources. However, the lead story on the WINEP website, "How Would Assad Use Chemical Weapons?," starts off: "US intelligence has detected increased activity at Syrian chemical warfare facilities, raising concerns about the regime potentially using chemical weapons (CW) against the opposition." Are the sources for that "US intelligence" WINEP istelf? Could things really be quite that incestuous? And—contrary to the conspiranoid assumption of a neocon-jihadist plot—the jihadists, like al-Nusra Front, seem to have made the neocons a little gun-shy in Syria. Insurgent sympathizers have been placing lugubrious propaganda videos on YouTube (via a stream called SyriaTube) luridly warning of an imminent chemcial attack. NBC News merely quotes anonymous US "officials" to the effect that "nerve agents" were loaded into warheads, without saying how this was determined. The agents are apparently "precursor chemicals for sarin," the gas that was used by Saddam at Halabja in 1988. Fox News merely cites the NBC account. The New York Times vaguely warns that stockpiles are being moved around to various of Syria's chemical weapons facilities, and that US officlals repeatedly warn Assad will be "held accountable" for their use...
