Re: 2009 April 21 - global warming
I enjoy the discussion here as it is at a higher level than normally seen on the web. I still have a problem with the "human caused global warming" science. As has been shown near the beginning of this discussion, climatic changes occur with or without humans. Also, there are cycles within...

Re: 2009 April 21 - global warming
So, how do we test the models? Well, we could run them backwards and see if they predict the past (they all fail). Where do you get this. In fact, the models all do a reasonable job of predicting the past over the ranges they are designed around (that is, there are long range models- thousands of y...

Re: 2009 April 21 - global warming
There were many comments about good science, bad science, and what not. Let us not forget the scientific method. That method requires the following Make observations on a subject (in this case global temperature changes) Develop an hypothesis based on those observations Make predictions based on the...
