Aerosols: heating or cooling?

The standard line in explanations of global warming to explain the disparity between rising carbon dioxide emissions and an absence of temperature increases in the period from 1940 to 1975 is that heating was precluded by the cooling of the atmosphere by aerosols, which when banned in the 1970's resulted in temperature rises.  Oops! it seems the scientific data totally contradict that explanation: a new study shows that aerosols cause temperatures to rise.
Now you would think this would be headline material.  Interestingly, the mainstream media has been rather silent about this latest scientific discovery.  Luckily for us Steven Milloy continues to monitor the world of junkscience, much to the continued dismay of his legion of critics.
Yet another inconvenient truth.  Can't wait to hear and read the convoluted explanations for this latest nail in the coffin of global warming.
At what point do we cease to explain away the litany of exceptions to the hypothesis and move forward to a more robust, accurate explanation of reality?
