NOAA study: Increase in stratospheric aerosols has offset some recent climate warming

Green Car Congress

The authors analyzed measurements from several independent sources—satellites and several types of ground instruments—and found a definitive increase in stratospheric aerosol since 2000. The increase in aerosols since 2000 implies a cooling effect of about 0.1 watts per square meter—enough to offset some of the 0.28
