Dr. Pierre Jutras, a geologist (could that be petroleum geologist?) from St Mary's University in Halifax, says:
The last time carbon dioxide levels were so low, near the end of the Paleozoic era (about 250 million years ago), the Earth's biosphere went through its greatest extinction, as 90 per cent of Paleozoic species were gone by the beginning of the Mesozoic era (age of the dinosaurs).
Well, it's always good to take a long view, but considering that the concentration of CO2 in the atmosphere is higher today than at any time in the last 650,000 years, humans seem to be dealing well with the current hostile conditions on earth.
Justras belittles climate change as an issue for “urban and economic planners,” the kind of people who care whether New Orleans or New York are swamped in an inevitable rise in sea level. You have to wonder if he's putting us on.
Even more, you have to wonder what is happening at the Globe and Mail that they would take this guy seriously and print his piece - even virtually. In a world crowded with serious scientists, it's hard to imagine why the Globe would entertain this diversion.
