In 1886, the US was hit by an incredible seven hurricanes, including two major hurricanes.
Suppose that some snake oil salesman named Hames Jansen had been running around the country in 1886 claiming that he could prevent hurricanes by having everyone give up coal and oil.
The consequences would have been catastrophic, had people been stupid enough to listen to Dr. Hames Jansen.
So why are people in 2012 stupid enough to listen to snake oil salesman James Hansen?
A great civilization is not conquered from without, until it has destroyed itself within. The essential causes of Rome’s decline lay in her people, her morals, her class struggle, her failing trade, her bureaucratic despotism, her stifling taxes, her consuming wars.
