Some People are Certifiable and Jim Hansen is Among Them

It's really a bit of a scandal that lunatics like Jim Hansen, the NASA climate alarmist, are taken seriously. This guy in endorsing a book that advocates ridding the world of industrial civilization is taking a position that would literally condemn billions to death, perhaps two thirds of the current population (See graph which starts in 1800).

The biosphere doesn't automatically provide for the human population. It takes technology and technology takes energy. Just go back about 100 years and ask what the world population was ... that's probably a little larger than we could sustain on such a program since a hundred years ago was well into the industrial revolution.
