The thing about science is that when you have data that contradicts the theory you're supposed to question the theory, not re-adjust the data ...
For the past several years supporters of the man-made global warming hypothesis have told us to ignore sunspot activity even though there was a direct corelation between sunspot activity and global temperature because sunspots did not effect the irradiance of the sun, and therefore should not increase the temperature of the Earth; a remarkably hypocritical stance being that CO2 emissions don't directly impact the temperature of the Earth either. We were told to ignore similar temperature changes on Mars and similar periods of warming on Earth, and accept the unproven theory as complete truth.
In 2008 and 2009 we had a massive drop in sunspot activity which has translated into a massive drop in average global temperatures in 2008, and 2009 is on track to being a much colder year than 2008. For example, the average artic temperature was still not above 0 degrees a couple of days ago and this is the latest day in the year in the 50 years that they have been tracking it that it has remained this cold this late into the year. There are several other statistics in ever country that are demonstrating that this winter (on the whole) was much colder than most in recent history, and (so far) this spring/summer isn't as warm as previous years.
The data indicates that the Sunspots we've been told to ignore plays a large part in the climate of the Earth. Unfortunately, the effect of sunspots has been associated to CO2 in climate models which are being used to justify policy changes that will greatly impact people's lives in a very negative way.
There is a certain element of humour to this though ...
If Sunspot activity stays unusually low over the next couple of years, and the Pacific Decadal Oscillation's cool phase gets up to "Full Strength", the US will be having average temperatures that are the lowest in a century when people start really feeling the impact of cap-n-trade.
