University of Arizona eyes a greener campus

…The oil industry peaked last year, and half of the oil in the world has been used up, said Guy McPherson, a professor of natural resources and ecology and evolutionary biology.

“If global warming is a three on a scale of one to 10, then peak oil is a 12,” McPherson said.

McPherson estimated a decline in oil supply during the next 20 to 30 years will account for the deaths of tens of millions of Americans. The current price of oil per barrel is $65, but within 10 years, oil is expected to cost about $400 per barrel, McPherson said.

“We will suffer more than any other country because we are so dependent on fossil fuels,” he said.
