Posted By: fostertom“Today more than 40% of EU gas is methane-heavy gas from Russia, which is worse than coal for the climate”That won't be a problem when Russia switches off the supply
Posted By: WillInAberdeenMethane-heavy natural gas, eh?Why not? I admit I thought I'd learned that 'natural gas' was pure methane, but was a bit surprised - would have expected a mixture of methane, butane, propane etc in varying proportions from different sources. So Russian may be 'methane-heavy'.
Posted By: fostertombut 'worse than coal'?Maybe, if the sources of natural gas are leaking more greenhouse effect in the form of unburned methane than the greenhouse effect of the carbon dioxide from burning coal.
Posted By: fostertomSo it should have read 'methane-leak-heavy gas
Posted By: Gavin SchmidtThis implies that if you convert the impacts of each set of emissions into temperatures, as was done in the IPCC AR6 report, you get about 0.75ºC from the changes in CO2 and 0.5ºC for CH4 (from the late 19th C, see figure below) or 1ºC and 0.6ºC, respectively, from 1750. Thus despite the smaller concentrations and changes in methane compared to carbon dioxide, the impacts are comparable.Remember, though, that it would be a one-off reduction. If CH₄ emissions are reduced then, over a decade or so, the temperature drops compared with what it would otherwise have done then continues to climb as a result of CO₂ accumulation.
