[geo] Updated Calcs for staying "well below 2.0 C" with GHG reduction alone

Updated data calcs. The 2019 estimate has been reduced, so going forward requires 4.7% yearly reduction rather than 6.1%, but as most of the decline in global GHG from 2019 to 2021 was due to the pandemic, the big question is whether global GHG emissions will plateau in 2023? In other words

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

Thank you Herbert. As a heterodox economist I generally agree with you with regard to the standard Neoclassical economics school of thought. But by “economically” in this case I was referring to the realism of thinking that near-term human civilization will collectively be able to cut and

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

Dear Colleagues, I’m a “radical”, or “heterodox”, economist so I think of economics (like other social sciences) as inherently based on values. But disregarding semantics perhaps we can all agree that unless the current global political economic regime hanged radically, over 6% GHG reduction

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

Dear Colleagues, Follow up to previous 1.5 C or 2.0 C post: c) Some quick calculation regarding the unrealistic economics of trying to stay below 15 c, or 1.8 C (per the "well below" 2 C of the Paris Accord) based on a purely voluntary NDC regime: As global GHG emissions have not declined by

Dear Colleagues, Segments 19:59 to 24:45 or so and perhaps a bit more in this excellent presentation (until it gets to the "fantasy economics" of postulating huge cuts and drawdowns in GHGs sufficient to stay below 1.5 c in the second part of the presentation - see c) in follow-up post) by Johan

Thanks for sharing, Herb! I haven't read the paper, but from a skim, it looks like maybe some sanity is emerging among climate modelers on this issue. Enough with "shaving the peak", it seems to me that we're going to need cooling (including probably OTEC type generating energy from and cooling
