John,
Been away. There isn't a simple answer to the question, even roughly.
They have caused some cooling, but a number depends on the climate
sensitivity. Best would be to look at the IPCC 3rd Assessment Report.
Cheers

Dear Dr. Phil Jones,
I hope that it will be possible for you to give a rough estimate to the following
question.
' What is the estimated cooling effect, in degrees Celsius, of Sulphates, Particulates
etc in the global atmosphere, on the global atmosphere at the surface and near to the
surface of the earth.'
All the Best,
John B Davies.
