I'm liberal, but I also have a science education. I don't like that some early 'global warming' data was deleted. The only thing that can mean is, they didn't want the data checked. But the Scientific Method is about reproducable results. Someone else has to look at the data and get the same results.
I recently saw mention of a scientist who stated he had been trying to tell other scientists that his theory was 30-40 years of warming, followed by 30-40 years of cooling. They ignored him, now he says this cold snap is part of what he predicted. More is on the way next winter.
I think it will be cold next winter.
