Arguing that Cop26 produced a weak declaration because of the unfairness of singling out coal over oil and gas.

There is some truth in that, but I think it is a matter of details. There are many powerful specific interests in one kind of fossil fuel or another. Whatever set of priorities among fossil fuel activities an international campaign might choose — including the set, "all fossil fuels are equally bad" — will arouse strong opposition somewhere. That opposition will create arguments about "fairness", all aimed at "reduce that other fossil fuel in that other region first".

There will be no fairness in the climate disaster we are heading for. Wealthy countries such as the US will be able to keep things going for longer than India.
