And there you go. Choose your time interval carefully and hey! It's always cooling!

Look at the total run of data and you reach a different conclusion. Which, BTW, is what the actual scientists actually say in the actual peer-reviewed literature.

“Because of the pronounced effect of interannual noise on decadal trends, a multi-model ensemble of anthropogenically-forced simulations displays many 10-year periods with little warming.  A single decade of observational TLT data is therefore inadequate for identifying a slowly evolving anthropogenic warming signal.  Our results show that temperature records of at least 17 years in length are required for identifying human effects on global-mean tropospheric temperature.”

So if you see any blogging about climate change trends that uses a less than 17 year window - grain of salt. If they conclude it's not happening - your baloney detector should redline.
