Using an extensive computer simulation of the climate, the global economy and the global energy system, researchers at Paul Scherrer Institute (PSI) have been analyzing different ways of mitigating climate change, together with colleagues from the US, China, Ireland, Finland and Sweden.
“It could be a close shave, because 70% of our scenarios predict that the world will exceed the 1.5°C mark in the next five years.”
Better find one that makes money or we will drag our feet doing it I presume.
Even if we found a way people would “scorch earth” to get the upper hand.
I’d be interested in seeing a list of descriptions of these scenarios. If we could determine the commonalities and use that to gauge a series of steps with impact vs effort analyses, it could take us a long way toward building out a plan to address climate change that may be more palatable to the collective global population.
They do discuss several commonalities in the paper.

If it is to meet the Paris Agreement target, the worldwide average carbon price in 2030 needs to be equal to today’s (2022) highest carbon taxes ($ 130–137 tCO2-1) that are observed in very few countries
Electricity cannot decarbonise the entire system alone, and hydrogen extends electricity’s reach to hard-to-electrify sectors
The contribution of nuclear power in electricity production increases in the long-term in the decarbonisation scenarios. This is especially pronounced after 2050/60, when the wind and other renewable potentials are fully exploited and the additional electricity supply to meet the increasing demand needs to remain carbon-free.
