There is a new push to reduce CH4 emissions as a possible quick ‘win-win’ for climate and air quality. To be clear this is an eminently sensible idea – as it has been for decades (remember the ‘Methane-to-markets’ initiative from the early 2000s?), but it inevitably brings forth a mish-mash of half-remembered, inappropriate or out-of-date comparisons between the impacts of carbon dioxide and methane. So this is an attempt to put all of that in context and provide a hopefully comprehensive guide to how, when, and why to properly compare the two greenhouse gases.

A bimonthly open thread for discussions related to climate solutions. Note that open discussions of climate science are here. Possible topics of interest are the trial carbon-capture effort in Iceland and the discussions in the lead up to COP26. Please be constructive and substantive.

This month’s open thread for climate science topics. Not sure about you, but we are still reading the details of the IPCC report. We are watching the unfolding hurricane season with trepidation, with particular concern related to the impacts of compound events (and not just those associated with climate), and anticipating another low, if not record, Arctic sea ice minimum.
PS. At some point this month we will be switching Internet service providers, so don’t be surprised if there are some oddities as we switch everything over.
