As Donald Kennedy, editor in chief of Science magazine, said of the subject: "Consensus as strong as the one that has developed around this topic is rare in science." Global warming is real. It is happening beyond the explanation of natural cycles; it is happening because of human contribution of greenhouse gases to the atmosphere. We are heading into an era of unprecedented climate change, the effects of which will be unlike anything our civilization has ever seen.
A campaign of disinformation has befallen us, striving to discredit the science and to give the illusion that there is still serious disagreement among scientists about global warming. The Bush-Cheney administration has been the primary source.
