You may have heard news reports about a funny gas smell in New York. The Wayne Madsen Report thinks it's oceanic methane;
There's some hard science that makes this plausible. Nature.com has an article about the massive methane out-gassing that triggered the early Eocene heating. What goes around comes around.
According to U.S. maritime industry sources, tanker captains are reporting an increase in onboard alarms from hazard sensors designed to detect hydrocarbon gas leaks and, specifically, methane leaks. However, the leaks are not emanating from cargo holds or pump rooms but from continental shelves venting increasing amounts of trapped methane into the atmosphere. With rising ocean temperatures, methane is increasingly escaping from deep ocean floors. Methane is also 21 more times capable of trapping heat in the atmosphere than carbon dioxide.
In fact, one of the major sources for increased methane venting is the Hudson Submarine Canyon, which extends 400 miles into the Atlantic from the New York-New Jersey harbor. Another location experiencing increased venting is the Santa Barbara Channel on the California coast.
Meanwhile, a strong natural gas odor was reported this morning in Manhattan, Brooklyn, Jersey City, Weehawken, and Newark. The strong odor was also detected in Union City, Secaucus, and Hoboken. Last August, a similar unexplained gas odor sent people to the hospital in Staten Island and Queens. Although methane is odorless, natural methane venting is often accompanied by the venting of acrid hydrogen sulfide, a byproduct of bacterial decomposition.
The US Coast Guard sent a message to ships and tugs in the bay and ocean south of New York requesting any reports of the odor being detected at sea. There were also an unconfirmed report of a similar strong odor being detected this morning on the Delaware coast near Lewes. This morning, the prevailing winds in New York and New Jersey were southerly at 5 to 10 miles per hour.
In other global warming news, the warm temperatures on the U.S. East Coast are resulting in early blooming of the cherry trees and azaleas in Washington, DC and New York City, apple and peach trees in Maryland, and roses, forsythias, and crocuses in Connecticut. A number of people along the East Coast are suffering from allergies usually experienced in April. Monk parakeets from South America have invaded the Chicago area.
George W. Bush continues to insist that global warming is "silly science" based on "fuzzy math." Corporate news media masters are pressuring plastic-faced and neatly-coiffured TV weathermen to treat the current abnormal warm weather as an unexpected "gift" for their viewers. The latte-sipping and SUV-driving yuppies in Washington, DC are certainly taking the current weather abnormality in stride -- they almost appear ecstatic about the weather, obviously unaware that the future of our planet is hanging on a thread.
About 55 million years ago, our planet emitted a spectacular burp. Trillions of tonnes of methane, until then safely locked up in soils and beneath the ocean floor, were released into the oceans and atmosphere. Methane is a greenhouse gas, so the result was a global-warming incident that has not been matched since — within a few thousand years, average temperatures in some areas rose by up to 8 °C.AlterNet has a piece looking at just how hard reversing global warming could be;
Although the evidence for this warming is clear, what sparked the methane release is a mystery. Some researchers believe that the trigger was a small change in ocean temperature. Others suggest that a comet impact was responsible. Analyses of cores from ocean-drilling experiments may soon provide the answer, but the results might do more than shed light on ancient climate — they may also tell us what the long-term consequences of current global warming are likely to be.
I'm not very optimistic that the public really wants to go there. I think the sad story of the East Coast fishery is instructive. The Grand Banks of Newfoundland used to have the most prolific cod fishery in the world. Old accounts from early sailors tell how they would lower a boat, swing an oar in the water and club a couple of fishes for lunch. No more. The Grand Banks sustained a lucrative commercial fishery for four hundred years until the methods switched to big factory ships and huge drag nets. Already in the 'eighties marine biologists were warning that the catch was unsustainable. But no politician concerned would dare impose realistic quotas.
Monbiot argues for a global carbon emissions cap allocated on a per capita basis. Since all of humanity shares the biosphere, which has only a limited absorptive and cleansing capacity and all humans are created equal, then each should have equal use of that capacity.
The implications of biospheric equity are so profound and so disturbing, that it is understandable why American environmentalists shy away from discussing the issue. Currently, global carbon emissions are about 7 billion tons, roughly, 1 ton per person. But the average American generates, directly and indirectly, some 10 tons per capita. Thus, to save the planet and cleanse our resource sins, Americans must go far beyond freezing greenhouse gas emissions. As a nation, we must reduce them by more than 90 percent, taking into account the sharp reductions in existing global emissions necessary to stabilize the world's climate.
Suddenly we realize that addressing the global warming problem will be very difficult, not only politically but economically and institutionally. And it may well entail significant sacrifice.
I well remember the then Minister of Fisheries, John Crosbie, thundering in the House in his thick Newfoundland accent about "not talking work from our fishermen." There were a few very profitable years and now the fishery is gone, probably beyond hope of recovery. Not diminished, not scaled back - gone. There is no commercial cod fishery in Eastern Canada. Unless this kind of greedy short-term thinking is changed, our whole civilization will be going the way of the cod.
