Latest Atmospheric methane Stories
An analysis of ancient Greenland ice suggests a spike in the greenhouse gas methane about 11,600 years ago originated from wetlands rather than the ocean floor or from permafrost, a finding that is good news according to the University of Colorado at Boulder scientist who led the study.
According to scientists, Greenlandâ€™s icesheet has revealed a store of methane that appears to be more stable that previously thought, easing tensions over a rapid rise in global temperatures.
New research is challenging the recent finding that plants could be a major source of the atmosphere's methane levels.
The common wisdom is that the invention of the steam engine and the advent of the coal-fueled industrial age marked the beginning of human influence on global climate.
On Wednesday, researchers said the arctic tundra emits the same amount of methane in winter as in the warmer months, a surprising finding that bolsters understanding of how greenhouse gases interact with nature.
The amount of methane in Earth's atmosphere shot up in 2007, bringing to an end approximately a decade in which atmospheric levels of the potent greenhouse gas were essentially stable.
Carbon dioxide is only one of the greenhouse gases that make scientists stay up at night. Methane and nitrogen trifluoride are increasing which makes scientists worry about increasing global warming.
Carbon buried in the Earth could ultimately determine the fate of our planetâ€™s atmosphere. So concluded a pioneering meeting last week about the Earthâ€™s long-neglected â€œdeepâ€ carbon cycle.
Researchers from the National Oceanographic and Atmospheric Administration Earth System Research Laboratory (ESRL) reported new data that shows a higher than usual average increase in carbon dioxide levels over the last 30 years.
