Good video, superb ending

This video about common climate change denier misconceptions (or lies, when repeated by those who have been told repeatedly that they aren't true, but whose stock in trade is to keep lying to people who believe their lies) has most of the regular stuff covered.

But what I found interesting was that they ended up with the common misconception / repeated misstatement / repeated untruth that during glacial/interglacial transitions during the Pleistocene, the rise in CO2 lags the rise in temperature.  The scientists pretty much understood this already, but the Shakun et al. 2012 paper (which you can read here) explained it all quite well with definitive proxy data.  This paper is one of the clearest and strongest demonstrations that CO2 is the primary atmospheric control knob on Earth's climate.  Because a rise in CO2 changes the radiative forcing of the atmosphere by absorbing more infrared (longwave) radiation, the CO2 we humans are adding to the atmosphere will cause the global climate system to get warmer.  Right this moment, it appears that most of the heat is going into the oceanic water column and melting polar ice.  But that may change and the incipient (hopefully) El Nino in the Pacific may push 2014 to an all-time high annual record temperature.

So everybody pay attention.
