"The result remains the gold standard for policy: global warming potential (GWP), which compares the impact of different greenhouse gases on climate." @KHayhoe @Wuebbles

🤔

That statement pulled me up...

I have no doubt about the statement before "When they argued that it was too difficult [to compare GHGs in a single metric], Houghton insisted that they must, because they were the best people in the world to do this."

Don Wuebbles was instrumental in the Ozone Depletion Potential (ODP) & the GWP uses essentially the same concepts.

Houghton pushed as there was a need to compare GHGs for policy, though, I am not sure scientists were so keen on the GWP at the time, nor the years later.

IPCC First Assessment Report “It must be stressed that there is no universally accepted methodology for combining all the relevant factors into a single [metric] ... A simple approach [ie the GWP] has been adopted here to illustrate the difficulties inherent in the concept.”

"Indeed, has there been what might be termed an “inadvertent consensus”, so that the IPCC & policymakers have each perceived that the other was content with the concept & didn’t apply pressure to fully assess alternatives?"

Have a read of the Editorial by Keith Shine, one of the fathers of the GWP, it is rather entertaining!

Not sure the GWP would be called the 'gold standard for policy'? @janfug @ReisingerAndy @oneill_bc

(Also read the section in IPCC AR5 WG1 Ch8)
