MIT team finds aviation emissions’ impacts on air quality larger than on climate

Researchers at MIT have determined that growth in aviation causes twice as much damage to air quality as to the climate. In an open-access paper in the journal Environmental Research Letters , they examine how this damage can be mitigated, and provide consistent comparative assessments of aviation emissions trade-offs, considering both climate and air quality impacts. Aviation emissions are an increasingly significant contributor to anthropogenic climate change.

Study finds that steady reduction in fossil fuel emissions will not result in short-term warming spike

Green Car Congress

One view advanced in some studies attempting to model future climate is that cleaning up fossil-fuel air pollution rapidly will unintentionally lead to a near-term rise in atmospheric warming of about a half-degree Celsius, which might take up to a century to reverse. Under all of these scenarios there is no significant spike in warming, no climate penalty, and we actually see a decrease in warming rates within two decades of the start of the phase-out.
