re: a warming trend
Tom Brosz — (archived)

Most reasonable people I know think there is a warming trend. Many other reasonable people I know also point out that the beginning of the current trend largely predates the industrial revolution (for example, the retreat of many glaciers began around 1700), and that there have been rapid changes of climate long before humans had fire.

It is also obvious that there is a connection between CO2 and temperature, if you look at the past tens of thousands of years, but I have yet to see anything nailing down cause and effect for this in earlier temperature changes, given the error in the graphs. The link does point out that dropping CO2 concentrations lagged cooling trends, which is telling.

That some of the current CO2 in the atmosphere is manmade is obvious. However, I don't see enough evidence to indicate that this CO2 is the sole reason for the warming, nor do I see evidence that shutting down human civilization is going to stop the warming trend. I will continue to oppose typical U.N.-type "mandates" which have far more political goals than they do environmental ones. On the other hand, I will support the use of alternatives to burning fossil fuels for energy, which would be a good idea even if there was no warming trend at all.
