Michael Oppenheimer quotes:

The only hope for the world is to make sure there is not another United States. We can't let other countries have the same number of cars, the amount of industrialization, we have in the US. We have to stop these Third World countries right where they are.

Mexican police will round up illegal American migrants surging into Mexico seeking work as field hands.

The only hope for the world is to make sure there is not another United States.

A hotter, moister atmosphere is an atmosphere primed to trigger disasters.

If we don't start with rapid emissions reductions and substantial emissions reductions, then we will pass a danger point, beyond which the consequences for many people and countries on Earth will simply become unacceptable and eventually disastrous.

The unthinkable is that we're distorting this atmospheric balance. We're shifting the chemical balance so that we have more poisons in the atmosphere - ozones and acid rain on ground level - while we're also changing the thermal climate of the earth through the greenhouse effect and - get this - simultaneously causing destruction of our primary filter of ultraviolet light. It's incredible. Talk about the national-debt crisis - we're piling up debts in the atmosphere, and the piper will want to be paid.
