The framework driving IPCC climate modelling has officially ditched the extreme scenarios as implausible, writes Roger Pielke jr in Climate Change Dispatch. The new framework has eliminated the most extreme scenarios that have dominated climate research over much of the past several decades — specifically, RCP8.5, SSP5-8.5, and SSP3-7.0.
The international committee responsible for the official scenarios that feed into climate modelling, which are the basis for most projective climate research and the assessments of the Intergovernmental Panel on Climate Change (IPCC), has just published the next generation of climate scenarios.
Tens of thousands of research papers have been — and continue to be — published using implausible scenarios and a similar number of media headlines have amplified their findings, and governments and international organizations have built these implausible scenarios into policy and regulation. We now know that all of this is built on a foundation of sand.
I don’t mind saying I told you so…see my 2022 book, Climate Alarm Reality Check (Wilkinson)
Roger Pielke Jr has called it “the most significant development in climate research in decades”.
No more hysteria, please.
