HTTP:: Arctic Sea Bed Releases Methane Gas
--------
In addition to carbon dioxide, the main gas held responsible for global warming, methane, is one of the most potent agents that can bring about climate change. Efforts of reducing emissions exist, but they are insufficient. To make matters worse, it has been recently confirmed that the gas escapes its Arctic sea-bed trap at an alarming rate. Its effects on the climate could be devastating, if efforts to reduce these amounts of released gas are not intensified, experts say, quoted by the BBC News. In a new scientific study, it was determined that about 250 plumes of methane came out of the ground at locations in the sea bed off the coasts of Norway. The methane is released following a vicious cycle. As more and more CO2 is emitted into the atmosphere, the growing temperatures heat up the Arctic ices, melting them, and allowing the methane trapped between frozen water crystals to escape in the atmosphere. This, in turn, leads to even more heating, which continuously acceler!
ates the release process, scientists believe. According to the joint German and British research team analyzing the plumes off West Spitsbergen, the methane comes from depths ranging from 150 to 400 meters below sea level. Details of the team's investigations appear in the latest issue of the respected journal Geophysical Research Letters. Metha...
