I never cease to be amazed by the myopic outlook of "experts"...

"The big unknowns are whether we can afford to do such projects and would we really know what to do. If the planet was cooling, we could, in principle, begin painting the surface black to collect more heat. Could we afford it? And what would be the many possible ramifications of a planet suddenly covered in black paint? Any planetary remediation project would always run the risk of making things worse."

*** We as a species have been a technolological scientific society for only a couple centuries at most. Unless the cultural realtivists win, we refuse to fight and lose our civilization thereby sliding into Islamist dark ages, our fundamental understandings after millenia and hundreds of millions of years (the time when the Sun's luminosity is the issue) will bear no semblance to today's inadvertant trashing of the environment.

The prospects of humans surviving by moving to some other habitable planet or moon aren't good, Brownlee and Ward contend, because even if such a place were found, getting there would be a huge obstacle. Various probes sent into space could survive Earth's demise, and just a few grams of material could arguably carry a DNA sample from every human, they say, but it's not likely the human species itself will survive. Long before the planet's final end, life will become quite challenging, and finally impossible, for humans.

*** It won't be humans per se that move to other planets and it certainly will not be any semblance to our species here when the oceans hear up. Do these "experts" have ANY vision at all?
