Senior business correspondent Amanda Lang of the respected Canadian Broadcasting Corporation’s Lang and O’Leary Exchange interviewed physicist and climate expert Michael Mann on Thursday about the accumulating magnitude and costs of climate change. (See the entire interview on video below.)
Like a resounding chorus of others, from the latest UN IPCC report authors to the passionate scientists and screen artists of The Years of Living Dangerously, Dr. Mann perceives opportunities for humankind in addressing the challenge—but doing nothing about heat-trapping emissions for another 15 years may make the problem unsolvable with known technologies and crippling to future generations, he thinks. The sooner we act, Mann says, the less it will cost.
In this interview Michael Mann stresses some major observations he’s made about the anthropogenic climate change we’re experiencing now and its projected near-term challenges. He also repeats the caution that we are approaching a whole new level of climate risk, one in which we may not be able to reverse some of the damaging consequences.
Lang asks Professor Mann point-blank what he thinks will be the tipping point in the climate change crisis. Watch the interview for his pointed reply. You’ll also gain insight into why Michael Mann says the costs to us of existing climate change (1% of global GDP) have begun to exceed the costs of taking action against greenhouse gases and other effects of cheap but ultimately dangerous fossil fuel consumption.
