Thanks for your polite reply, Michael. I've followed the issue closely for years and I have no doubt that global warming is a natural happening. I think humans may affect it, but not much; however, I don't know how to quantify it. I have not seen any good figures indicating how much humans affected it. I have yet to see any calculation about the amount of greenhouse gases expelled by Nature. I guess that makes me a crank or an oil company flak. I suppose we're not allowed to discuss such matters on this site, so fine, thanks, I'll shut up. -- Joe
Oh jeez, can we let this thing go? The science is clear for global warming as a human-affected phenomenon. There are a few cranks and oil company people who have an interest is sowing disbelief, but the debate in the scientific community is now about specifics--not about the overall trends.
The earth is also roughly spherical, not flat. There are no water-sprites in your garden. There is no boogey man under the bed. The pyramids were not built by aliens.

The history of global warming is a fact that global warming alarmists can't really explain. Warmer climate conditions than we now have existed during the Medieval Warming Period and during the Greek, Persian and the early Roman era. These temperature records are validated both by Sargasso Sea data and Greenland ice cores. Any theory of global warming that attributes most of the current warming to man-made causes must explain why the earth was warmer during these periods.
I think variability of the sun is the main factor controlling global warming with man made influences mainly in the noise of the data. In fact particulate emissions may actually have a cooling effect as seen briefly after 9/11 when flights were grounded and the temperature rose. This may have been a coincidence.
The Clear Sky Clock predicts clear weather in Salt Lake until this evening for the transit of Mercury.

Caution: this article may prove to be more satisfying to global-warming cranks than to global-warming believers:

The linked "References and detailed calculations" PDF file is a 40-page "force multiplier": if the article pleases you, the PDF file will probably please you more; if the article displeases you, the PDF file will likely increase your displeasure. :-)
