Yes, the Intergovernmental Panel on Climate Change has said that man is at the root of most of Earth's warming in the last five decades.

Sallie Baliunas, an astrophysicist at the Harvard Smithsonian Center for Astrophysics, is pointing to a slide called Interdecadal Magnetic Variability Berillium 10. Its supposed to communicate something about the relationship between the suns intensity and climate change. All I see is a collection of squiggly lines. It could be an EKG or a seismograph test. The man sitting next to me appears to be equally lost. Hes snoring. The woman next to him is staring at her shoelaces.
