One year of cooling can't offset 100 years of warming, and it applies the other way also.
The trend has been 100 years of warming with a mid-century cooling. With reports from NASA, NOAA and NSIDC, I think we could be seeing a mid-century cooling possible. The only way anyone will know for sure is to look back on 10-20+ years of data and look for any sort of a trend.
You have to consider all factors that effect this planets temps; oceans, the atmosphere, ice caps and the sun. We are in a prolonged "solar minimum" right now that started in the summer of 2006, possibly caused by the sun changing it's magnetic flux. I found this snippet in the paper just now.

No knee jerk reactions, just common sense and doing what's right. And polluting less helps out everyone and everything.
