Courtesy The Powerline Blog, I visited Urgent Agenda and found this gem of a letter on the subject of Anthropogenic Global Warming.
Read it all.
(2) It is obvious that anthropogenic global warming is not science at all, because a scientific theory makes non-obvious predictions which are then compared with observations that the average person can check for himself. As we both know from our own observations, AGW theory has spectacularly failed to do this. The theory has predicted steadily increasing global temperatures, and this has been refuted by experience. NOW the global warmers claim that the Earth will enter a cooling period. In other words, whether the ice caps melt, or expand --- whatever happens --- the AGW theorists claim it confirms their theory. A perfect example of a pseudo-science like astrology.
(3) In contrast, the alternative theory, that the increase and decrease of the Earth's average temperature in the near term follows the sunspot number, agrees (roughly) with observation. And the observations were predicted before they occurred. This is good science.
(4) I emphasized in point (2) that the average person has to be able to check the observations. I emphasize this because I no longer trust "scientists" to report observations correctly. I think the data is adjusted to confirm, as far as possible, AGW. We've seen many recent cases where the data was cooked in climate studies. In one case, Hanson and company claimed that October 2008 was the warmest October on record. Watts looked at the data, and discovered that Hanson and company had used September's temperatures for Russia rather than October's. I'm not surprised to learn that September is hotter than October in the Northern hemisphere.
It snowed here in New Orleans last week and it was the second heaviest snowfall I've seen in the 25 years I've lived in New Orleans. According to the local newspaper, it was the earliest snow had fallen in New Orleans since records were kept, beginning in 1850. I myself have looked at the relative predictive power of Copernicus's theory and the then rival Ptolemaic theory. Copernicus was on the average twice as accurate, and the average person of the time could tell. Similarly, anybody today can check the number of sunspots. Or rather the lack of them. When I first starting teaching astronomy at Tulane in the early 1980's, I would show sunspots to my students by pointing a small $25 reflecting telescope at the Sun, and focusing the Sun's image on the wall of the classroom. Sunspots were obviously in the image on the wall. I can't do this experiment today, because there are no sunspots.

(7) I agree with Dick Lindzen that the AGW nonsense is generated by government funding of science. If a guy agrees with AGW, then he can get a government contract. If he is a skeptic, then no contract. There is a professor at Tulane, with a Ph.D in paleoclimatology, who is as skeptical as I am about AGW, but he'd never be considered for tenure at Tulane because of his professional opinion. No government contracts, no tenure.
Sun Spots: Not just for Amateur Radio Operators anymore.
Now, climate change is real enough. We have plenty of historical, and archaeological, evidence that the climate changes. Things warm up, they cool off.
Empirical evidence is that some human activities can have an impact on the local climate-i.e., turn an agricultural paradise into a howling desert, build reservoirs in a different desert--but all that proves is that the local climate changed. Empirical observation is not scientific theory! Empirical evidence is what you use to devise a theory, which then needs to be tested! The media, and liberals in general, are all about post hoc, ergo propter hoc, which does not necessarily play out in real life.
Personally, I suspect that the Brazilians cutting down the Amazon Rain Forest to plant
