Another Scary IPCC Climate Change Bomb Defused - Scientists Say Greenhouse Gas Fear Overblown
Scientists determine IPCC hysteria about global warming causing Arctic methane gas "tipping point" release to be unfounded - it's not happening
Read here. The UN's IPCC, 'Big Green' and Climategate scientists are all about alarming the public and policymakers, actual science be damned. In this case, the usual scare-culprits came up with a theory that CO2 warming of global will cause a super release of the powerful greenhouse gas methane that would lead to a "tipping point" and "runaway" global warming.
And as it almost always turns out with the IPCC and Big Green, their hysterical climate change predictions are found to be meritless. The research team of Dmitrenko et al. pretty much defused this blown out of proportion prediction, adding to the incredibly long list of failed IPCC fear mongering prognostications.
"So despite a warming Arctic, the feared large methane release has not been manifest. Which fits very nicely into the new results from Dmitrenko and colleagues. They find that the methane observed to be bubbling up from the Arctic seafloor off the coast of Siberia to be the ongoing and long-term response to the flooding of the seabed there that occurred some 8,000 years ago and not a response to recent warming in the region...Dmitrenko et al. write: The CH4 [methane] supersaturation, recently reported from the eastern Siberian shelf, is believed to be the result of the degradation of subsea permafrost that is due to the long-lasting warming initiated by permafrost submergence about 8000 years ago rather than from those triggered by recent Arctic climate changes...The new Dmitrenko result pretty much throws cold water on the “shocking” news that has been making its way through the global media in recent days that reports from a recent survey of the Siberian Arctic Shelf indicate that vast quantities of methane are bubbling to the surface of the ocean and that this is “stok[ing] new global warming fears.” [Igor A.
