I chuckle when somebody insists CO2 is a greenhouse gas and that’s all there is to it. Virtually all expert science would say, then, don’t worry about CO2 because the direct effect of increased CO2 is easily calculated to be only about 1 degree Celsius of warming from an expected atmospheric doubling later this century.
To make CO2 responsible for the warming already observed—1.2 degrees—scientists have to posit “positive” or warming feedbacks. In a new paper, veteran NASA scientist James Hansen offers a larger estimate of the (ironically) negative feedback from particulate emissions. This negative feedback (cooling) becomes, in effect, a positive feedback (warming) only because our efforts to curb air pollution allow more sunlight to reach Earth’s surface.
