Hi

I wanted to get another perspective on CH4 for myself to understand and in order to explain to others - and compiled the following table

Does this compute? I used your graph below to estimate the GWP of 1GT CH4 released over selected periods of 25 and 50 years relative to CO2

CO2 equivalent warming potential per 1 GT CH4 released
Current global average CH4	ppb	1890	1890
Current global average CH4	ppm	1.89	1.89
Time period CH4 release and decay	Years	25	50
IPCC equivalent CO2 warming equivalent over time	%	65	45
IPCC equivalent CO2 warming equivalent over time	ppm	123	85.05
Current global CO2	ppm	397	397
CH4 as % of current CO2 warming	%	31	21
Present amount of CH4 in atmosphere	GT	5	5
Ratio current GT CH4 in atm to ppm	GT:ppm	0.38	0.38
Increase in CO2 equivalent per GT CH4 released	ppm/GT	34	24
Total CO2 equivalent ppm in atm if 1 GT CH4 released	ppm	431	421
Increase in CO2 warming equivalent per GT CH4 released	%	9	6
