Gray states that the last century's global warming of about 1 degree F is not a consequence of human activities. This warming is primarily the result of a multi-century changes in the globe's deep ocean circulation.
I find it always interesting that the professionals who come out against "Anthropogenic Global Warming" -- also -- confirm that there has been "Global Warming".
I think it's about time that certain other FReepers also recognize that the "real existence" of "Global Warming" does not mean that one cannot fight against the false science and false assertion of "Anthropogenic Global Warming"...
Even Lord Monckton confirms that he believes that there has been "Global Warming" but he does not think there is such a thing as "Anthropogenic Global Warming"...
At the moment the climate seems to be cooling....but it has cycles.
