Do I believe there are greenhouse gases? Of course.
I just dont think it is an eminent problem, CO2 emissions will never reduced without doing it at the expense of this country and the population as a whole. As third world countries such as india, China and so on continue to become the manufacturing hubs of the world they will continue to out produce the U.s. in emissions. Much of the problem I believe is the over population of the world and the expansion of cities. Everyone worries about cutting down trees in our national forests but there is never a discussion when cities expand and knock the single most combative item on the planet against CO2, vegetation.
Without things that convert CO2 out of the atmosphere on this planet the levels will continue to rise, even if we reduced our CO2 emissions to 0 in this country. Methane will continue to rise as well, especially as the population grows, since mathan is produced by making the very thing we as a species need to survive, that is food.
Climates have changed on this world for centuries...now it sounds like we will go into a cooling period....
The computer you are on discussing about climate change has increased the CO2 level ....see the hypocrisy in this. Everything we do, increases the CO2 level, it can not be stopped.
My policy towards environmental issues and the world is a lot like taking a bath. When you take a bath, you will always get the water dirty. But you don't take a crap in your bath tub. The U.S. is getting the water dirty, other countries are crapping in the bathtub. We haven't been craping in our bathtub, but we still have to sit in it no matter what we do.
