Society's emissions of carbon dioxide may or may not turn out to have something significant to do with global warming-the jury is still out.

The scientist is not responsible for the laws of nature. It is his job to find out how these laws operate. It is the scientist's job to find the ways in which these laws can serve the human will. However, it is not the scientist's job to determine whether a hydrogen bomb should be constructed, whether it should be used, or how it should be used. This responsibility rests with the American people and with their chosen representatives.

Physics is, hopefully, simple. Physicists are not.
