I do not think that Global Warming is happening by itself without our influence. I would say that our global climate at one time occured naturally-- but not anymore.

For example, if the US emits more greenhouse gases per person than any other country in the world. Greenhouse gases come in many different forms. For example, the natural ones that occur in our atmosphere--which seems to be what Roberto and others were referring to-- are those like water vapor, carbon dioxide, methane, nitrous oxide, and ozone. However, if these are occuring naturally without our input, I would say that is ok, however, this is not the case. We are emitting more carbon dioxide because of our cars; more methane becuase of production of coal, and the list goes on. In addition to this "Fossil fuels burned to run cars and trucks, heat homes and businesses, and power factories are responsible for about 98% of U.S. carbon dioxide emissions, 24% of methane emissions, and 18% of nitrous oxide emissions"--EPA. Not only are we emitting that much we are also cutting down so many trees through deforestation and not allowing the excess CO2 get absorbed by these trees.

So if some of you are going to sit back and say that our earths global warming is occuring "naturally" then I beg to differ. The EPA has suggested that:

"Human activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gases – primarily carbon dioxide, methane, and nitrous oxide."--EPA

Before someone goes ahead and trys to debunk what I have said, try debuking the Environmental Protection Agency. I do know that there are some uncertainties, but I do think that if we have been emitting more gases that have had to be emitted then we must be doing something to alter the atmosphere.
