A sane world would be dramatically cutting fossil fuel use now. CO2 concentrations are already at levels not seen in at least 3-5 million years, before humans existed, when trees grew in Antarctica and sea levels were something like 65 feet higher. Levels might even be greater than they were 23 million years ago. John Lennon said, “Our society is run by insane people for insane objectives . . . by maniacs for maniacal ends.” Like bank and oil company executives and their bought-and-paid-for politicians who are driving the world headlong into catastrophe.
