Joseph D’Aleo, Executive Director at ICECAP did some analysis with the latest version of the Historical Climatology Network Version 2, looking at various correlations with the new data, here is his findings summary:
SUMMARY USHCN temperatures show a cyclical behavior over the past 112 years with peak warming about 1930 and 2000. The temperature trends correlate with a number of factors. We examined them here. We found the correlation strengths to be as follows:
Clearly the US annul temperatures over the last century have correlated far better with cycles in the sun and oceans than carbon dioxide. The correlation with carbon dioxide seems to have vanished or even reversed in the last decade.Given the recent cooling of the Pacific and Atlantic and rapid decline in solar activity, we might anticipate given these correlations, temperatures to accelerate downwards shortly.
I have been following the Sun, Sunspots and shifts in the Pacific Ocean Oscillation with correlations to local temperatures changes. Therefore,I found this correlation chart quite interesting.
Much of the rain and snow we are having right now is the result of a La Nina which may be an early indicator that the Pacific has shifted to a cool phase. This shift will bring us back to the weather we had between the 1940 and 1970s. It was a lot colder and wet in the winter and spring. I remember one year when it seemed to rain from December to May.

UPDATE: Anthony Watt's at Watts Up With That has a detailed analysis to this paper. Read the whole paper and this excellent analysis, with links to some supporting papers.
