Hi Andy--Growing up in 1950s with college in early 1960s, I'll admit I'm an idealist, and likely naive, but what is that old saying: "Never wrestle with a pig. You get dirty and the pig likes it." (for attribution controversy, see https://quoteinvestigator.com/2017/07/08/pig/) As noted in my

Replies appreciated. It is obviously provocative for Peter Fiekowsky to compare views of climate scientists to claims that health scientists made for tobacco companies and that oil company scientists made about climate actions. I think there is a real difference, in that climate

Important discussion and Mike’s point about roles and sequencing has merit, but may be. missing an important negative feedback loop. That loop exists when the ethical frame of one faction in civil society, let’s say represented by EWG, is used to demonize and prohibit relevant science itself.

Dear Peter--A couple of comments: 1. What reducing methane emissions would do is to reduce the radiative forcing over the ensuing decade or two. With the heat from the higher levels having built up in the ocean, the time for recovery of the temperature (and climate)  is longer, so until the

Robert- Good point about the scientists uniformly calling for delaying implementation, essentially indefinitely, since they don't offer any criteria for actually starting to restore safe methane levels and protect against a methane burst. Do you think this is an ethical issue? Doubling the
