Pay no attention to the man behind the curtain or the global cooling that may throw off the global-warming computer models

 Parts of North America and Europe may cool naturally over the next decade, as shifting ocean currents temporarily blunt the global-warming effect caused by mankind, Germany's Leibniz Institute of Marine Sciences said.

``If we don't experience warming over the next 10 years, it doesn't mean that greenhouse-gas warming is not with us,'' Keenlyside said in an interview. ``There can be natural fluctuations that may mask climate change in the short term.''

So the "natural" cycles can affect the "man-made" climate change. Isn't that fascinating?
