BIRD DOG at Maggie’s place sieves one up that I saw but neglected to post.
…science reality in 2008 is that the IPCC’s hypothesis of dangerous, human-caused global warming has been repeatedly tested and failed. In contrast, the proper null hypothesis that the global climatic changes that we observe today are natural in origin has yet to be disproven. The only argument that remains to the IPCC — and it is solely a theoretical argument, not evidence of any kind — is that their unvalidated computer models project that carbon-dioxide-driven dangerous warming will occur in the future: just you wait and see!
