I'm not sure what the point of this study is. Despite serious efforts at obfuscation by the fossil fuel sector over the past 40 years, it's now widely know that the basic science of climate was solved by the late 1970s (1). Everything since then has been a refinement of the fundamental concept, i.e. that infrared-absorbing atmospheric gas concentraion is a primary control on a planet's surface temperature (along with other factors like albedo, soot and dust levels, etc.). Humans have, primarily by the combustion of fossil fuels, steadily pushed towards a doubling of the levels of the long-lived IR-absorbing gases CO2 and CH4 in the atmosphere. This should take place (we hit 560 ppm) around 2050 at the earliest. Perhaps a betting pool would be the thing? Fossil fuel combustion is the main driver of global warming, as we can see by noting the reduction in 14C in the atmosphere due to dilution with 14C-lacking fossil-sourced CO2 emissions. That also was known by 1980 (2). 1. https://www.princeton.edu/news/2021/10/05/princetons-syukuro-manabe-receives-nobel-prize-physics https://www.princeton.edu/news/2021/10/05/princetons-syukuro... 2. https://www.cambridge.org/core/journals/radiocarbon/article/effect-of-anthropogenic-co2-and-14c-sources-on-the-distribution-of-14c-in-the-atmosphere/1D7E05C4973B4AC2766A5A6F2C18553B https://www.cambridge.org/core/journals/radiocarbon/article/...
