Gavin Schmidt: "Our ability to properly quantify the air pollution around the world … is actually not very good"

NASA data shows that the ‘pause’ in global warming continues | The Daily Caller: "“Our expectations for what temperatures should be changing like, they come from our understandings of our forcings of climate change,” Schmidt said, adding that such forcings include greenhouse gases, volcanoes, solar activity and air pollution — for example, aerosols from coal burning, smog and volatile organics.

“Our ability to properly quantify the air pollution around the world … is actually not very good, and we have had historically a problem in defining those aerosol forcings very accurately … and that has not improved,” Schmidt admitted."
