$this->bbcode_second_pass_quote('dohboi', 'A')gain, for lurkers: AGW is based on very basic, incontrovertable facts--
1. CO2 is a greenhouse gas (established beyond question over 100 years ago)
2. We have dumped hundreds of billions of tons of CO2 into the atmosphere by burning ff
3. CO2 atmospheric concentrations have risen over the last 150 years
4. Global temps have increased over the last hundred years
No deniers can question the basic truth of any of these, and only a confirmed denialist would fail to connect these very clear dots.
There is a lot more to it than that, Dohboi. I received a Geology degree from the 5th best academic Geology program and the best funded program in the USA. My play toys in the department were scanning electron microscopes and isotopic spectrum analyzers. I was an intern (he called me "his slave", LOL) and received precious personal tutelage from one of the most famous Geology professors in the USA, Robert Folk. He created some of the classification systems used by all geologists in the world today, like the Folk sedimentary rock classification system. Ok, enough academic chest thumping but I wanted to establish some authority. There is a lot of misinformation and conjecture in this thread.
Your causality that you established above is not iron clad. The earth has been warming for 11,000 years, not just the past 150. The earth has been transitioning from a cold house to a hot house environment for 11,000 years. The earth's poles have been without ice in previous hot house environments.
What I am concerned about is the rate of change humans are effecting on the world's environment. This is not limited to CO2. The problem is much larger than that. Species exist within environmental niches. We are changing the world's environment so fast, thus changing species' niches more quickly than they can adapt, that massive extinction, possibly the greatest extinction event ever, is now underway. Resource depletion (forests, minerals, fossil fuels, fish stocks, fresh water, productive soil) is increasing at a parabolic rate, which is completely unsustainable. We are rapidly making our world unlivable for most of its inhabitants. Creating more CO2 is just one very small slice of the environmental pie.
As far as science goes, there are tens of thousands of scientists who have signed onto proclamations saying that they do not agree that global warming can be directly attributed to human activity. There are studies which have been performed on ocean warming which claim to absolutely establish global warming and CO2 levels ties to human activity. There are many isotopic studies on ice and carbonate layers which show parabolic spikes in greenhouse gas levels starting 500 years ago, coinciding with the dawn of industrialism in England. The question is, how much is this going to really change our environment in the next 100-200-500 years? No one really knows the answer to that question.
I personally think that human activity is destroying this planet and we may be too far along the slippery slope to stop, unless we kill 85% of the world's population with an engineered plague or something. Human activity is changing not just the atmosphere, but ground water, oceans, soil, and especially animal and plant life. CO2 is one small facet of the problem.
As far as Cap and Trade goes, in my opinion it's just another tax by the bankers (or their lackeys, the government). I have heard, but I don't know if it's true, that home inspections and fines will created by this bill. I don't know if this is true, I'd like to see confirmation somewhere. So to me, it's just another excuse for more governmental control over our lives. I think there is a better solution to this problem than this tax and control bill.
