I've often heard it said that there's a consensus of thousands of scientists on the global warming issue and that humans are causing a catastrophic change to the climate system. Well I am one scientist, and there are many that simply think that is not true.
John Christy...it is fairly well agreed that the surface temperature will rise about 1°C as a modest response to a doubling of atmospheric CO2 if the rest of the component processes of the climate system remain independent of this response.
John ChristyI was at the table with three Europeans, and we were having lunch. And they were talking about their role as lead authors. And they were talking about how they were trying to make the report so dramatic that the United States would just have to sign that Kyoto Protocol.
John Christy[W]e are not morally bad people for taking carbon and turning it into the energy that offers life to humanity in a world that would otherwise be brutal (think of life before modernity). On the contrary, we are good people for doing so.
