Remember when it was warming, and they told us that coal-fired power stations were causing it? Now they tell us that coal-fired power stations have a *cooling* effect

Global warming has slowed because of pollution - Telegraph
Global warming has slowed in the last decade, according to the Met Office, as the world pumps out so much pollution it is reflecting the sun’s rays and causing a cooling effect.
...
But in a new report the Met Office said the reduced rate of warming can be easily explained by a number of factors. And indeed the true rate of warming caused by man made greenhouse gases could be greater than ever.

One of the major factors is pollution over Asia, where the huge growth in coal-fired power stations mean aerosols like sulphur are being pumped into the air. This reflects sunlight, cooling the land surface temperature.

Dr Vicky Pope, Head of Climate Change Advice, said pollution may be causing a cooling effect.
