yes, agreed, there must be something that is more powerful than CO2 AT THIS POINT IN TIME. The real question is whether that external event that is impacting the trend is an outlier and transient or if it is the beginning of a new trend that invalidates the GW theory.

I have to tell you, again speaking as a statistician, that 8 years of up and down data, not uniformly below trend, does not give me very much confidence that a long term trend has been broken. The rule of thumb for the possibility that a trend line has been broken is 6 or more data points in sequence above or below the regression line. The data I've seen has not shown enough sequential data below the trend line to warrant a break from trend. That means, the probability is high that the last 8 years have been outliers caused by a transient event.

Maybe Solar radiation and Sunspots??

The sun has always been the case! But the variation in energy output is a fraction of a percent between the peak of a typical solar cycle and solar minimum.

Looks like we won't have to worry very long. The sun is perking up now with more sunspots beginning to appear the last few months.

Here is a couple good websites that I follow that have lots of info:
