That the climate has always changed. It has never been static. In the past it has seen extremes hotter and colder than what we experience today. So c… - Anthony Watts

As I've always said, the sun is the "Big Kahuna" of climate change on Earth. Everything else is secondary, even though man's opinion of his own self importance in the scheme of things often dictates otherwise.

I'm not sure the "remarkable Arctic warmth" is real, especially since the disappearance of arctic sea ice during that time has been linked not to warmer temperatures, but to wind patterns by other researchers at NASA.

Global warming had become essentially a business in its own right. There are NGOs, there are organizations, there are whole divisions of universities that have set up to study this, this factor, and so there's lots of money involved and then so I think that there's a tendency to want to keep that going and not really look at what might be different.
