There is very little evidence that man-made CO2, etc has made any impact on the climate.
However, it's ridiculous when people claim that we are going to have a noticeable climate change if we don't stop burning coal/oil/gasoline at our current rate.
These are the two parts of your statement I find fault with. There is in fact quite a bit of evidence that there is a strong correlation between CO2 concentrations and climate shifts. If you had there is not enough evidence then You statement would reflect your opinion and would be perfectly valid. Many are unconvinved by the present data, but that is no reason to stifle further research which to your credit you say you support.
Your second statement is ripe for picking apart. Your use of absolutes is discouraging and points towards you having your mind made up already by something other than solid scientific research. Why do you think it is so "ridiculous" that something humans do could affect the environment. We have affected the rivers and oceans and even groundwater systems and the air around our cities. Why is it impossible to believe that nothing we do could possibly affect weather systems?
I am by no means a rabid environmentalist and am disheartened by the statements made on both sides of the fence. Some envirowhackos go running with incomplete science and make a huge deal out of things, while at the same time people who profit from raping the Earth want us to believe that there is no danger ahead. I have done considerable research in this field and have come to the conclusion that like most things, the truth is somewhere in the middle. In this case I believe the truth leans towards the side of the environmentalists but is still close to center.
There are certian things that we should be willing to do such as moving towards renewable energy sources. It must be done eventually so why not start making those steps. The innovations that come with these investments will fuel the economy producing a new industry, with tons of service, manufacturing and research positions. The benefits are for everyone. We cant continue to be dependant upon the middle east for our energy. A large portion of every dollar we spend on gas and oil products in the US goes right overseas into the pockets of the tyrants we dislike so much. Reducing our oil useage is good for all americans in many ways.
