The atoms become like a moth, seeking out the region of higher laser intensity.

Sustainable energy is the equivalent of the U.S. moon shot.

So imagine a world 6 degrees warmer. It's not going to recognize geographical boundaries. It's not going to recognize anything. So agriculture regions today will be wiped out.

If other countries don't impose a cost on carbon, then we will be at a disadvantage...we would look at considering perhaps duties that would offset that cost.

Somehow we have to figure out how to boost the price of gasoline to the levels in Europe.

For the better part of my last semester at Garden City High, I constructed a physical pendulum and used it to make a "precision" measurement of gravity. The years of experience building things taught me skills that were directly applicable to the construction of the pendulum. Twenty-five years later, I was to develop a refined version of this measurement using laser-cooled atoms in an atomic fountain interferometer.

While we cannot accurately predict the course of climate change in the coming decades, the risks we run if we don't change our course are enormous. Prudent risk management does not equate uncertainty with inaction.
