methane under pressure
rather than solid
methane hydrate continuing to dissociate, assuming no
methane flows in from surrounding areas, and so on.

methane,
rather than increased melting in deep sediments — isotope ratios ought to help clarify that.
By basing the levy on emissions
rather than carbon all greenhouse gases stand on a common level, sequestration is strongly encouraged as well as such simple things as capturing
methane from oil wells and garbage dumps (that gets built into the cost of disposal).
Because the carbon that stimulates
methane production is primarily dissolved organic carbon carried downward through the peat by rainwater
rather than the solid - phase carbon that forms peat, this change in transport depth doubled the peak production zones for
methane.
«[Howarth et al.'s] analysis is seriously flawed in that they significantly overestimate the fugitive emissions associated with unconventional gas extraction, undervalue the contribution of «green technologies» to reducing those emissions to a level approaching that of conventional gas, base their comparison between gas and coal on heat
rather than electricity generation (almost the sole use of coal), and assume a time interval over which to compute the relative climate impact of gas compared to coal that does not capture the contrast between the long residence time of CO2 and the short residence time of
methane in the atmosphere.»
In the agricultural sector, most of the approximately 5 million metric tons of CO2 equivalent emissions are from

Thus, the problem with the proposals currently being discussed in Congress: They will, for the foreseeable future, direct private investment toward the least expensive emissions reductions (such as burning
methane from landfills, purchasing forest land for carbon sequestration, or retrofitting power plants and buildings so they operate more efficiently)
rather than toward breakthrough technologies (like low - cost solar energy and carbon capture and storage), which are too expensive to become widely adopted today but which are vital for creating a new energy economy and thus drastically reducing emissions.

methane levels.
Robert Howarth, an environmental biology professor at Cornell University, used research from the United Nations to calculate that if
