DOH! Global warming caused by ... cleaner air!

My God. What will the enviro-nuts do now?

When the effects of global warming are discussed, Europe is often the focus. While many parts of the Earth have seen little or no warming in the past two decades, Europe has seen a rapid temperature increase of one full degree Centigrade. The rise has been a contributing factor in at least one deadly heat wave in recent years.

A new study suggests much of that warming isn't due to global warming at all, but rather a decrease in atmospheric pollution as a result of clean air legislation. The cleaner air has fewer small particles known as aerosols, which tend to block sunlight from reaching the Earth's surface. A reduction in aerosols leads to an effect known as "solar brightening," which increases surface warming. (Link.)

What a conundrum, eh?
