The world must spend tens of trillions of dollars in the next ten to 15 years to avoid the catastrophic effects of global warming, according to climate change expert, Michael Molitor. A senior adviser on carbon management to PricewaterhouseCoopers and adjunct professor at UNSW's Climate Change Research Centre, Molitor will give a public talk at UNSW on 23 April, 2008.

He will address four burning issues facing the world on climate change.

What is the scale of the problem and when should we act?What will it cost to avoid the catastrophic effects of global warming?Who's going to pay to reduce carbon emissions?What should we spend the money on?

Dr Molitor says climate change has moved rapidly from being a scientific issue to a policy challenge to a significant business opportunity. "General Electric, one of the world's leading industrial companies, sees low-carbon technologies as one the greatest business opportunities in history," he says.
