Scientists find clues to greenhouse gas mystery A team of international scientists has discovered why levels of methane, the second most important greenhouse gas, have stabilized in recent years but they warned on Wednesday that the trend may not last. Reduced and more efficient use of natural gas in the Northern Hemisphere in the 1990s had helped methane levels in the atmosphere to stabilize. Rising emissions from fossil fuel use in north Asia since 1999 have threatened to push up atmospheric levels but this has been balanced by lower emissions from wetlands as they dry up. "Had it not been for this reduction in methane emissions from wetlands, atmospheric levels of methane would most likely have continued rising," said Dr Paul Steele of CSIRO Marine and Atmospheric Research in Australia and an author of the study published in the journal Nature. If the drying trend of wetlands is reversed and emissions from them return to normal levels, atmospheric methane will increase again and could worsen global warming, according to the authors. Scientists say the Earth is getting hotter because of human activities, notably the release into the atmosphere of greenhouses gases which let in sunlight and trap its heat like the walls of a greenhouse. "Methane is an important greenhouse gas and this work is a major step in better understanding why methane emissions are changing," said Professor Neville Nicholls, an expert on climate change at Monash University in Melbourne, Australia. "But the relentless increase in carbon dioxide emissions from fossil fuels is, and will continue to be, the most important driver of the global warming we are witnessing," he added in a statement. The scientists used computer simulations to track back to the source of methane emissions and how the gas is transported in the atmosphere.

the universe and God are generally unconcerned about the feelings and opinions of Britain's leading scientific academy. The scientific minds that have made up the membership of the Royal Academy over the centuries (Newton, Dirac, Maxwell, Einstein etc etc) have never purported to have influence over god or the universe. They merely observe it. www-groups.dcs.st-andrews.ac.uk The sycophants, quacks and meddlesome alchemists of the Exxon Mobil Corp. appreciation society have no historical record of being accurate except for saying the things that Exxon Mobil Corp. want to hear. They do not have peer review, do not use scientific method, and present a fraudulent case that the climate is not changing. That is why the Royal Society made it's complaint.
