Teller on Global Warming

An interesting article has appeared in The Guardian on UC-Berkeley physics professor and his predictions of global warming. Teller was much better known as the father of the H-bomb, his participation in the Manhattan Project, and his postwar testimony against former Berkeley physics professor J. Robert Oppenheimer in the aftermath of the Project.

Excerpt from Teller's remarks to a conference on the hundredth anniversary of the oil industry in 1959:

Ladies and gentlemen, I am to talk to you about energy in the future. I will start by telling you why I believe that the energy resources of the past must be supplemented. First of all, these energy resources will run short as we use more and more of the fossil fuels. But I would [...] like to mention another reason why we probably have to look for additional fuel supplies. And this, strangely, is the question of contaminating the atmosphere. [....] Whenever you burn conventional fuel, you create carbon dioxide. [....] The carbon dioxide is invisible, it is transparent, you can’t smell it, it is not dangerous to health, so why should one worry about it? 

Carbon dioxide has a strange property. It transmits visible light but it absorbs the infrared radiation which is emitted from the earth. Its presence in the atmosphere causes a greenhouse effect [....] It has been calculated that a temperature rise corresponding to a 10 per cent increase in carbon dioxide will be sufficient to melt the icecap and submerge New York. All the coastal cities would be covered, and since a considerable percentage of the human race lives in coastal regions, I think that this chemical contamination is more serious than most people tend to believe...
