Professor Carter on AM Friday 21st January. Listen here.
BOB CARTER: Lots of scientists have been looking for that evidence but to date there is nothing in the scientific literature which says we have more climatic emergency events at the moment than in the past or that these are more frequent or more dangerous. There is no scientific evidence for that.
MEREDITH GRIFFITHS: Professor Carter says it's not surprising that last year was one of the warmest, but says that doesn't mean greenhouse gases are the blame.
BOB CARTER: The question is not whether it causes warming, the question is how much warming? Since 1998 we've had three warm years - 1998, 2005 and 2010 - and each of those years is associated with an El Nino event which causes or is related to the warming. Okay, but there's no trend, 2010 is not significantly warmer in any way than 1998.
So we have a warm period over a period of 12 years. Over those same 12 years we have a five per cent increase in carbon dioxide in the atmosphere. The carbon dioxide is supposed to cause more warming. Well this data that we've just discussed tells you that human carbon dioxide emissions are not causing dangerous global warming, indeed they're not causing any warming at all at the moment.
MEREDITH GRIFFITHS: Professor Carter says the last 150 years have been among the coolest in the past 10,000 years of the Earth's history.
