Pollution Methane levels hold steady Levels of the greenho role gas methane work plateaued for the jump time in about 200 years, shows a notify in Geophysical Research Letters. Methane is second only to coulomb dioxide in contributing to our planets warming. The gas - belched out by fossil-fuel burning, rice paddies, festering farm manure and landfill sites - has been accumulating since the industrial revolution. directly the tide may be turning, say Ed Dlugokencky of the discipline Oceanic and Atmospheric Administration (NOAA) in Boulder, Colorado, and his team. They found that levels stabilise between 1999 and 2002, according to measurements from 43 ground-based stations around the world. The resolve for the change is unclear. Dlugokencky believes that a big contributing factor was the break-up of the Soviet Union in 1991. Oil and gas resultion fell, and the labor became more efficient at plugging gas leaks from pipes and wells. Experts say the plateau is no cause for complacency. Increasing fossil-fuel consumption in ontogeny nations, or renewed drilling for natural gas, might further methane again. The trajectory is still moving up, says David Blake, an atmospheric chemist at the University of California, Irvine.

The finding highlights how small steps to cut methane emissions could slow globular warming, he says. Leaking gas pipelines could be capped and incentives introduced to encourage landfill owners and farmers to use methane to run power generators. Earlier studies hinted at a retardant in the long-term rise in methane - but Dlugokenckys certainty is based on particularly frequent and accurate measurements.. Taiwan, the largest maker of compact discs in the world, will begin to recycle this product as early as next July, when required regulations have been established, Environmental defense Administrator Chang Juu-en said yesterday. Officials from the Environmental Protection Administration (EPA) yesterday were criticized by... If you want to get a serious essay, order it on our website: Orderessay
