The resultant
CH4 emission trajectories in the four SRES markers are displayed in Figure 5 - 17.
Based on this source list, future
CH4 emission trajectories depend upon such variables as volumes of fossil fuels used in the scenarios, regional demographic and affluence developments, and assumptions on preferred diets and agricultural practices.
Not exact matches
To consider such feedback, the forcing has to be the actual action that is disturbing the amount of CO2 and
CH4 (anthropogenic
emissions), and a good description of the response may be time - dependent (
trajectory of climate as a function of
trajectory of anthropogenic
emissions).
Overvaluing the influence of
CH4 emissions on climate could easily result in our «locking» the earth into a warmer temperature
trajectory, one that is temporarily masked by the short - term cooling effects of the
CH4 reductions, but then persists for many generations.
