Methane in atmosphere today is at 2 ppm, carbon dioxide is at 420 ppm. If methane is 20 times more potent, this implies that atmospheric methane is equivalent to 40 extra ppm of carbon dioxide.
If we removed literally all methane from the atmosphere, this would be equivalent to reducing carbon dioxide concentration to 380 ppm. This would bring us back to climate of 2005. By any reasonable measure, climate in 2023 is not significantly different than the climate in 2005 (eg. you’d hardly be able to observe any difference without making a lot of very careful measurements, you wouldn’t “feel” any difference on your own skin).
And that’s if we remove literally all methane. Most of the methane in atmosphere is a result of natural processes, not caused by human activity. Thus, if we stop all methane emissions caused by human activity, we can maybe at best slow down climate change by 10 years. In terms of practical effects as felt by human beings, this is accurately described as “won’t change a thing”. Actually, to be more specific, slowing climate change by 10 years won’t make any difference, but stopping all methane emitting activities would be tremendously negative to human flourishing.
