No warming left to deny

From Pierre Gosselin, the noted skeptic, the information is that the planet is now cooling and has been for the past fifteen years.

“Looking at the data for the last decade or so, one thing stands clear: Global temperatures have been showing many more signs of cooling than warming. Already we are sensing that global temperature has lost the battle to stay up. The HadCrut data series above shows that cooling has gained the upper hand. Indeed warming is now in the history books, having died some 15 years ago.”

It does not matter whether the planet is cooling or warming, what is at issue is whether mankind is causing either. It is very likely that, if the planet is cooling, we are not causing it. Is it not reasonable to infer that we were not causing it to warm, too, when it was warming?
