Perhaps some group might be capable of producing a climate model that correlates the periodicity of natural climate change events like volcanic eruptions, tectonic shifts, etc. with the measured, natural increase in our Sun's energy output, and the measured growth in the technological human population. The next step would be to incorporate the result of such a "Kentucky Windage" climate model into the "best so far" data of the Earth's available/accessible human needed resources such as food production, water use, and manufacturing raw materials. Lastly, measurement of what's estimated against what's actually happening would be needed to provide a basis for human decision making. Face it. The Sun has ~5By left on the Main Sequence. During that time, Earth bound H. Sapiens will go extinct, sooner or later; hopefully, later. To be cynical, today's predictions/admonitions/fears of climate change/global warming sound like "Hoots in Haydes" of the "sooners" who appear as rapacious special interests, and political power mongers. N.B.: Dismissing out of hand the dire consequences predictions of climate change/global warming should not be done. Neither should marked, wholesale political decisions be imposed on societies based on today's "guesstaments" or the panicky "it's almost too late to do anything so do X,Yand Z right now". Today, the roadmap into our climate future seems foggy.
