Patrick, Some comments on your letter:

The very likely part is because the report, and science, do not act in complete certainty, there is always the probability of being wrong, we have to accept our limitations. A "very likely" cause, is something we should consider. To illustrate with a simple example, it is very likely you can break some bones if you fall from a 5-story building. There is a chance you will not break any bones, but its unlikely. > Has anyone studied whether a large proportion of global warming is being > caused by an increase in geothermal heating of the oceans?

Solar radiation does varies, but it doesn't seem to be the cause. > Am I missing something here, or does it really not add up?

Unfortunately this is the most common argument from the skeptics, and I can't understand it. You won't accept what the science can provide and demand other explanations because you can't accept that humans can have an impact. There are more than 6 thousand million people, a thousand million of those running to match the US lifestyle in China. One person may be too small, but we are just too many. Why not even consider we MAY be having an impact. What about the ozone layer hole? We did that. Therefore, we are able to have an impact. Furthermore, there are many correlations and models that back the conclusion. Yes, there may be another cause, but I better be safe than sorry. We owe it to the future generations. Luis J.
