Prior to Shindell's work, such calculations had
assumed aerosol impacts were uniform around the globe.
The maximum temperature change is about (0.19 +.10) 0.3 C. Still not close to the actual of 0.5 C. Thats
assuming the aerosol impact is zero, but it's not.
Not exact matches
In particular, the
impacts of sulfate
aerosols and additional (non-CO2) greenhouse gases currently cancel out, so it was
assumed that they would keep cancelling and could therefore be ignored.
