The hallmark of good science is the testing of a plausible hypothesis that is then either supported or rejected by the evidence.

Too much ice is really bad for polar bears.

The warming we've experienced in the late 20th century could just as easily be explained by small decreases in cloud cover - natural changes in the system - and have nothing to do with CO2.

There is no experimental data that exists that supports the view that the Earth's climate is changing in any dangerous way.

Changes in clouds and rainfall can overwhelm what little effect CO2-water vapour has on temperature.

Changes in solar activity have influenced what has been called the "conveyor-belt" circulation of the great Atlantic Ocean currents over the past 240 years.

There is some CO2-water vapor feedback. But it's not operating on a global scale. The modellers cannot accurately separate water vapour from the effects of clouds and rainfall.

...a magical CO2 knob for controlling weather and climate simply does not exist!

I am a scientist. I go where the facts take me.

Solitude is strength to depend on the presence of the crowd is weakness. The man who needs a mob to nerve him is much more alone than he imagines.

My mother taught me about the power of inspiration and courage, and she did it with a strength and a passion that I wish could be bottled.

Songwriters can sort of get away with murder. You can throw out crazy theories and not have to back it up with data or graphs or research.

I can't help but note that God is being useful to a lot of people trying to do harm to one another.

A young lady ought to be two things: tasteful and breathtaking.

Reality is devoid of any intrinsic identity that can be captured by any one single proposition - that is what Buddha meant by "voidness."

Humans tend to build walls when they should be opening doors.

I'm certainly not tired - work doesn't tire people, it's getting bored that's tiring.

You may use different sorts of sentences and illustrations before different sorts of audiences, but you don't -- if you are wise -- talk down to any audience.

You feel you can pretend to be young until you're 50, but after that, what happens and how do you approach it?
