Climate change

He has taken part in a review of the 2007 Intergovernmental Panel on Climate Change.

Murty characterizes himself as a global warming skeptic. In an August 17, 2006 interview, he stated that "I started with a firm belief about global warming, until I started working on it myself...I switched to the other side in the early 1990s when Fisheries and Oceans Canada asked me to prepare a position paper and I started to look into the problem seriously.".^[1] Murty has also stated that global warming is "the biggest scientific hoax being perpetrated on humanity. There is no global warming due to human anthropogenic activities."^[4] Murty was among the sixty scientists from climate research and related disciplines who authored a 2006 open letter^[5] to Canadian Prime Minister Stephen Harper criticizing the Kyoto Protocol and the scientific basis of anthropogenic global warming.
