That no warming since ... canard is just cherry picking the end points. The data show the climate is warming over the long term. 2012 was a record warm year since we have had direct measurements.
The melting Arctic ice is playing havoc with the jet stream and this means that the north/south waves are more extended and slower moving and weaker. Cold air is spilling down farther south sometimes. Just because the overall temperature averages are rising doesn't mean that all cold weather goes away.
It has been over 27 years since we had a record cold month.
