I think the Caribbean countries face rising oceans and they face increase in the severity of hurricanes. This is something that is very, very scary to all of us. The island states in the world represent - I remember this number - one-half of 1 percent of the carbon emissions in the world. And they will - some of them will disappear.

Switching to light-coloured roofs and roadways would have the equivalent effect on greenhouse gas emissions to taking one billion cars off the road for eleven years.

If I were emperor of the world, I would put the pedal to the floor on energy efficiency and conservation for the next decade.

Science is really about describing the way the universe works in one aspect or another in all branches of science-how a life-form works, how this works, how that works. ... You have to have a natural curiosity for that.

I also developed an interest in sports, and played in informal games at a nearby school yard where the neighborhood children met to play touch football, baseball, basketball and occasionally, ice hockey.

I approached the bulk of my schoolwork as a chore rather than an intellectual adventure.

Coal is my worst nightmare.
