Re: [prag] Re: [geo] Are 1.5 c or 2.0 c thresholds economically realistic in a voluntary NDC regime?

 Another way to articulate what Robert said is to  quote  Keynes: “Anything we can actually do we can afford.” Economics can help guide us on the most resource sparing means to achieve a goal, but the setting of the goal is inherently value based and politically mediated.  It seems that there are at least three possible goals with respect to the climate crisis: Our current goal - Avoid the worst impacts by limiting temperature increases to well below 2° C by 2100 even if we temporarily exceed that goal-  Avoid the activation of tipping points by limiting temperature increases to well below 2° at all times by shaving peak temperatures Restoring a healthy climate by limiting temperature increases to well below 1° C Herb Herb Simmens Author A Climate Vocabulary of the Future @herbsimmens On Apr 8, 2023, at 9:13 AM, David desJardins <da...@desjardins.org> wrote:  On Sat, Apr 8, 2023 at 4:59 AM Robert Chris <robertgch...@gmail.com> wrote: David, no matter what the goal may be, it is always economically realistic. So long as global warming is mediated through an economic lens, the likelihood of a happy ending is pretty remote. I'm confused. Don't these two statements contradict one another?  -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
