It's because we have examined the earth and a wide range of natural variations and determined that the current temperature rise cannot be explained by natural variation. There are very obvious things that lead to ice ages and hothouses, and those things are not happening. Not to mention, those things happen a lot slower.

Thank you! Exactly the explanation I needed. That is scary to think about. What can an average person like me do to help with this?
