guest is close to the mark when he says that those who provide the funding set the agenda. The studies, however, are funded by different groups. Some research is based on the theory of multiple prejudices, and progresses by knocking them down, leaving the most likely as a basis for further study.

During the Eocene period, the northern hemisphere was subect to "global warming," with plants and animals (including alligators)typical of modern counterparts in the Carolinas, existing on the Arctic Islands. This was the result of a combination of factors, none of them due to man, who would not appear on the scene for another 60 million years or so.

We have had many small swings documented in the past few thousaand years. Man is contributing CO2 and other substances, but how much of the present warming is the result of geological/solar changes and how much to these activities of man?

I believe that man's contribution is too large to ignore, but I understand why there are skeptics.
