WebApr 11, 2024 · CO 2 remains in the climate system for a very long time: CO 2 emissions cause increases in atmospheric concentrations of CO 2 that will last thousands of years. Methane (CH 4) is estimated to have a GWP of 27-30 over 100 years. CH 4 emitted today lasts about a decade on average, which is much less time than CO 2. But CH 4 also … WebJun 3, 2016 · The long-term effect of methane emissions might appear to be a lot greater than it really is when compared to carbon dioxide in terms of both gases’ potential to warm the climate. The Oxford researchers suggest a new way to account for methane that highlights the considerable differences in how each gas turns up the atmospheric furnace. WebWe have constructed an atmospheric inversion framework based on TM5-4DVAR to jointly assimilate measurements of methane and δC-13 of methane in order to estimate source-specific methane emissions. Here we present global emission estimates from this framework for the period 1999–2016. We assimilate a newly constructed, multi-agency … software technology ppt
