Dan,

Re: CO2

very few people are aware of how incredibly quickly we are changing the atmosphere.

Do you know that just by breathing, you are adding CO2 to the atmosphere? So please do you part and stop making things worse.

Joe

Dear Dan3: It is my understanding the biggest cause of the increase in CO is the burning of the rain forests in S. America for farmland (slash and burn technicues) and volcanic eruptions (forgot the name of the ones recently). Auto pollution has much less effect with the cleaner burning engines we have today.

Dan - *OT* My daughter did her undergraduate work in environmental engineering (with a minor in Political Science so that she would understand how to put environmental theory into practice) and her senior thesis was originally going to be based on an analysis of the Mauna Loa work. She was at that time a big believer in the greenhouse theory and was basing her thesis on the need for widespread government action to reverse the trends.

But she is also a pretty good scientist, and in the course of her research came across a number of studies suggesting that the Mauna Loa work was incorrectly considering micro effects as indicative of macro trends. This lead her into a broader analysis of the various relationships between fossil fuel use and the shifts in CO2 and other greenhouse gasses. Her thesis eventually shifted to a study on the social and environmental impact, and the real economic costs, of programs designed to correct effects based on a single and rather narrow set of assumptions when the effects of those programs can not be measured for years.

She is still on the fence on this issue, but I was exposed to enough discussion on the topic to convince me that it is far from open and shut that the assumptions about the greenhouse effect are supported by accurate theories about the causes and trends.

Thanks for the links, that is certainly one side of the debate.
