Ivar Giaever quotes:

I am a skeptic...Global warming has become a new religion.

In the APS (American Physical Society) it is ok to discuss whether the mass of the proton changes over time and how a multi-universe behaves, but the evidence of global warming is incontrovertible? The claim (how can you measure the average temperature of the whole earth for a whole year?) is that the temperature has changed from ~288.0 to ~288.8 degree Kelvin in about 150 years, which (if true) means to me is that the temperature has been amazingly stable, and both human health and happiness have definitely improved in this 'warming' period.'

Incontrovertible is not a scientific word. Nothing is incontrovertible in science.

Is climate change pseudoscience? If I'm going to answer the question, the answer is: absolutely.

I'm a skeptic. ...Global Warming it's become a new religion. You're not supposed to be against Global Warming. You have basically no choice. And I tell you how many scientists support that. But the number of scientists is not important. The only thing that's important is if the scientists are correct; that's the important part.

To me the greatest moment in an experiment is always just before I learn whether the particular idea is a good or a bad one. Thus even a failure is exciting, and most of my ideas have of course been wrong.

If you want to do good research, it's important not to know too much. This almost sounds contradictory but really if you know too much and you get an idea, you will sort of talk yourself out of trying it because you figure it won't work. But if you know just the right amount and you get enthusiastic about your project, you go ahead, you do it and if you're lucky things'll work out.
