Despite the frequent attempts to claim otherwise, the scientific community does not unanimously believe in man-made global warming. And now, more than 17,000 scientists have signed a petition to that effect, stating:

There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gasses is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth.
