Study Rules Out Ancient 'Bursts' Of Methane From Seafloor Deposits
ScienceDaily (Aug. 24, 2006) —
A dramatic increase about 12,000 years ago in levels of atmospheric
methane, a potent greenhouse gas, was most likely caused by higher
emissions from tropical wetlands or from plant production, rather than
a release from seafloor methane deposits, a new study concludes.

•• Note: 12,000 ago was just at the end of the last ice age

This research, to be published Friday in the journal Science,
contradicts some suggestions that the sudden release of massive
amounts of methane frozen in seafloor deposits may have been
responsible -- or at least added to - some past periods of rapid
global warming, including one at the end of the last ice age.

The findings were made with analysis of carbon isotopes from methane
frozen in Greenland ice core samples, by researchers from Oregon State
University, the University of Victoria, University of Colorado, and
the Scripps Institution of Oceanography at the University of
California-San Diego.

For climate researchers, an understanding of methane behaviour is of
some significance because it is the second most important "greenhouse
gas" after carbon dioxide.

•• Bull****!!! The ONLY important GHG is H2O which
comprises 12,387 parts per MILLION or 97% of the
total. Methane @ 1.745 parts per BILLION is too
insignificant to count. CO2 is measured @ 385 ppm
and is constantly being recycled.

Its atmospheric concentration has increased about 250 percent in the
last 250 years, and it continues to rise about 1 percent a year.

•• ROTFLMAO - How much is 1% of 1.745 parts per billion. 0.01745 ??

Your just plain wrong about global warming apparently because you're blinded
by republican bull **** and pap from the "scientific experts" like Limbaugh.

This is one of hundreds of recent articles about warming effect happening
now. You need to pull your head of that dark place and take a look without
republican prejudice and BS coloring your judgment. You sound foolish and
ignorant like Inhofe.
