NASA’s top climatologists reported the same thing in 1971, and made it clear that the effects of CO2 are not dangerous, and never will be dangerous.
Obama’s science adviser John Holdren reported the same thing in 1971, and predicted a new ice age in a joint paper with Paul Ehrlich.
Ehrlich also reported that the US would have food and water rationing by 1980.
NOAA shot this theory down by the year 1977, so it is pretty remarkable that Gavin is trying to resurrect it in 2015.
