More About Global Warming Deceit

I received an e-mail encouraging me to check out the 10 part series about the global warming debate that has appeared in the Canadian press lately. It provides a lot of good reading about how false premises may have lead so many astray in searching for a cause of climate change. That is not new. This site has linked lots of such material. What struck me was the source.

I got the e-mail from a friend. He happens to be a scientist (albeit, nuclear, not climate) and professor at Berkley. He got it from a colleague who called the source paper, The National Post, his "national paper of choice when we are up here [in Canada.]" That indicated to me that it is more than a rag.

Back to the series of articles. It is summarized in the last segment linked above:

Dr. Shariv's digging led him to the surprising discovery that there is no concrete evidence -- only speculation -- that man-made greenhouse gases cause global warming. Even research from the Intergovernmental Panel on Climate Change-- the United Nations agency that heads the worldwide effort to combat global warming -- is bereft of anything here inspiring confidence. In fact, according to the IPCC's own findings, man's role is so uncertain that there is a strong possibility that we have been cooling, not warming, the Earth. Unfortunately, our tools are too crude to reveal what man's effect has been in the past, let alone predict how much warming or cooling we might cause in the future.
The scientist quoted, Dr. Shariv, studies space, rather than the earth. He believes that cosmic rays from the sun drive climate change. He estimates that cosmic rays could adjust the earth's temperature by up to 15%, sufficient to turn ice ages on and off. On the contrary, he does not believe that "greenhouse" gasses have such an effect. In fact, he considers them so insignificant that doubling them would have no effect. Meaning that halving them would not matter, either.

It seems to me, we should know more about all of this before we start crippling economies with drastic changes in energy use.

What, are you some kind of heretic? For shame, challenging the orthodoxy!

No time to respond. I think the inquisitors are at the door.
