Sentences with phrase «cause atmospheric methane»

An instantaneous release, for example, would cause the atmospheric methane concentration to spike immediately, then decay back toward the unperturbed value on a time scale of approximately one decade.

«As these — rice and cattle — were once big sources, their lack of continued increase would then cause atmospheric methane to stop increasing as well.»

Not exact matches

Since methane can cause about 20 times as much atmospheric warming as carbon dioxide, curbing methane would help slow global warming.

«Our data suggest that when the icebergs entered the North Atlantic causing exceptional cooling, the rainfall belt was condensed into the Southern Hemisphere, causing tropical wetland expansion and abrupt spikes in atmospheric methane,» she added.

Small wonder atmospheric methane can cause such global catastrophe considering its dramatic rise during the last few years, as elucidated by Carana on 5 December 2013 in the figure below.»

A study surveying «leaky valves and pipes in the rapidly growing natural gas industry» observed 50 % more methane leakage than expected, but the extra atmospheric contribution still causes less global warming than coal.

What is concerning is the possibility that rapid global warming could occur faster than many people believe is possible, if global warming due to atmospheric carbon dioxide causes the Earth's atmosphere to warm enough to release enormous deposits of frozen methane (CH4) that are stored in the permafrost above the Arctic Circle and in frozen methane ice, known as methane hydrate, underneath the floors of the oceans throughout the world (see: How Methane Gas Releases Due To Global Warming Could Cause Human Extinmethane (CH4) that are stored in the permafrost above the Arctic Circle and in frozen methane ice, known as methane hydrate, underneath the floors of the oceans throughout the world (see: How Methane Gas Releases Due To Global Warming Could Cause Human Extinmethane ice, known as methane hydrate, underneath the floors of the oceans throughout the world (see: How Methane Gas Releases Due To Global Warming Could Cause Human Extinmethane hydrate, underneath the floors of the oceans throughout the world (see: How Methane Gas Releases Due To Global Warming Could Cause Human ExtinMethane Gas Releases Due To Global Warming Could Cause Human Extinction).

This led to the «early anthropogenic hypothesis» that early agriculture caused the observed (and anomalous) reversals in the natural declines of atmospheric CO2 (carbon dioxide) near 7000 years ago and CH4 (methane) near 5000 years ago.

Since a sustainable future based on the continued extraction of coal, oil and gas in the «business - as - usual mode» will not be possible because of both resource depletion and environmental damages (as caused, e.g., by dangerous sea level rise) we urge our societies to -LSB-...] Reduce the concentrations of warming air pollutants (dark soot, methane, lower atmosphere ozone, and hydrofluorocarbons) by as much as 50 % [and] cut the climate forcers that have short atmospheric lifetimes.

On longer timescales, our results show that the decrease in atmospheric methane growth during the 1990s was caused by a decline in anthropogenic emissions.

Two studies published in April 2017 suggest that recent increases in atmospheric concentrations of methane may not be caused by increasing emissions.
