Methane is too unstable in an atmosphere like ours to build enough of a concentration to be a greenhouse threat.
More Fake News.
Once again, it seems that you have taken the minority view. Don’t
@me because I CBFd giving oxygen to laypersons who think that they know better than phd level academics. It’s like arguing with an oncology radiologist that you don’t have cancer because you read up about it on the weekend and saw some stuff on youtube.
Researchers from Stockholm University on the icebreaker Oden in the Arctic Ocean
reported from the site that "vast methane plumes" were rising from the ocean floor probably due to a tongue of warmer Atlantic water that is penetrating into the Arctic. The observation shocked the scientists on board who issued a
press release. A recent
news story on the Oden's mission also reflected their strong concerns.
Meanwhile, a crater spotted in the frozen Yamal peninsula in Siberia earlier this month was probably caused by methane released as permafrost thawed due to higher temperatures, researchers in Russia say. The science journal Nature carried a
report of the finding.
The Problem with Methane
Methane is a greenhouse gas as is carbon dioxide. Human activity has increased the amount of methane in the atmosphere, contributing to climate change. Methane is particularly problematic as its impact is 34 times greater than CO2 over a 100-year period, according to the latest
IPCC Assessment Report. A significant source of human-made methane emissions is fossil fuel production. For example, methane is a key by-product of the rapidly rising global extraction and processing of natural gas. Other top sources of methane come from the digestive process of livestock and from landfills, which emit it as waste decomposes.
