It is always a delight to read a clear discussion of good data and what it means. It is all the more delightful when it supports the position I like and uses the very data of the enviro-nanny-fascists to directly refute their concepts.
CO2 might have had a serious effect on global climate. The theory was worth examining. It has been examined and effectively disproved by actual events.
Mr. Hoven is correct to view either a 30-year trend or a 10-year trend as rather short. The cycling of temps within the instrument record seems to indicate that we are seeing only normal variations. The doubts about the validity of the instrument record are also well-founded.
As far as instrument records go, I have read repeatedly (I don't have the cite handy) that satellite temperature monitoring has had no discernible trend in thirty years. These cover more of the planet with more consistent measuring tools than anything on the surface. One of the things that hampers James Hansen's credibility is his refusal to use the satellite data when it comes from his own agency.
