Lord Christopher Monckton, who criticizes the climate change people for a vast over-reach, was at the recent Rio Summit. The gathering received little coverage, but it is worth noting its tone.
"(D)uring the UN's Rio+20 summit last week, the walls of the conference center were festooned with disturbing images, many painted by children under the rubric, 'children teaching their parents.'
"In one painting, a child painted the sun, dressed as a doctor taking the temperature of the earth. The diagnosis? 'I'm sure you have humans!'
"Our children are being taught by fraudulent scientists and extremists that people are a plague!"
