Now, for the moment, we are safe. The only kind of international violence that worries most people in the developed countries is terrorism: from imminent heart attack to a bad case of hangnail in fifteen years flat. We are very lucky people--but we need to use the time we have been granted wisely, because total war is only sleeping. All the major states are still organized for war, and all that is needed for the world to slide back into a nuclear confrontation is a twist of the kaleidoscope that shifts international relations into a new pattern of rival alliances.

But we are almost certainly going to miss our [global warming] deadline. We cannot get the 10 lost years back, and by the time a new global agreement to replace the Kyoto accord is negotiated and put into effect, there will probably not be enough time left to stop the warming short of the point where we must not go.

As the most religious country of the 18 surveyed, the U.S. also comes in with the highest rates for teen pregnancy and for gonorrhea and syphilis.

Never did anyone ever stay longer than ten years because the resistance grows fiercer as your presence grows longer [in Afghanistan]. I don't think we are going to be any exception. What made us exempt from history?

There is a point of no return after which warming becomes unstoppable - and we are probably going to sail right through it. It is the point at which anthropogenic (human-caused) warming triggers huge releases of carbon dioxide from warming oceans, or similar releases of both carbon dioxide and methane from melting permafrost, or both. Most climate scientists think that point lies not far beyond 2 degrees C hotter (3.6 degrees F).

The real requirement, if we are to avoid runaway global warming, is probably 80% by 2030, and almost no burning whatever of fossil fuels (coal, gas and oil) by 2050.
