Too hot to handle?

I have read Global warming: A Time to Act by Dianne Feinstein. She argues about global warming, the issues at hand and the ways to eliminate green house gasses.

Greenhouse gasses are the main causes for global warming. These gasses are created by the burning of fossil fuels and the excretion of carbon dioxide. The United States is the largest contributor to the destruction of our planet through pollution that enables global warming to occur. We have to stand up and act together in order to eliminate the excess we produce and consume in order to save our mother earth. Only we can save ourselves so we need to start immediately in reducing the amount of fossil fuels we consume and the carbon dioxides we create.
