Latest Atmospheric methane Stories
ESA's Earth-observing satellites are helping to understand the intricate role that Eurasia's boreal forest â€“ the planet's largest land ecosystem â€“ plays in the chemical make-up of the atmosphere and the global climate system.
Concentrations of greenhouse gases approached record levels in 2009 and could set off even greater methane emissions from the Arctic, the UNâ€™s weather agency warned Wednesday.
Methane in the atmosphere of Mars lasts less than a year, according to a study by Italian scientists.
40,000 years ago rapid warming led to an increase in methane concentration.
By examining 800,000-year-old polar ice, scientists increasingly are learning how the climate has changed since the last ice melt and that carbon dioxide has become more abundant in the Earth's atmosphere.
The extinction of mammoths and other megafauna that came after humans spread out across the New World may be one explanation of a sharp decline in global temperatures more than 12,750 years ago.
A section of the Arctic Ocean seafloor that holds vast stores of frozen methane is showing signs of instability and widespread venting of the powerful greenhouse gas.
The surprising increase in methane concentrations millennia ago, identified in continental glacier studies, has puzzled researchers for a long time.
Canadian scientists say stressed crops emit more methane than thought and could result in a bigger global warming problem than currently forecast. University of Calgary scientists said when crops are exposed to environmental factors that are part of climate change -- increased temperature, drought and ultraviolet-B radiation -- some plants show enhanced methane emissions.
Scientists at the University of Calgary have found that methane emission by plants could be a bigger problem in global warming than previously thought.
