...there be a third future? That will depend on whether we succeed in holding proliferation at bay. Iran is the test case. It is the most dangerous political entity on the planet, and yet the world response has been catastrophically slow and reluctant. Years of knowingly useless negotiations, followed by hesitant international resolutions, have brought us to only the most tentative of steps--referral to a Security Council that lacks unity and resolve. Iran knows this and therefore defiantly and openly resumes its headlong march to nuclear status. If we fail to prevent an Iranian regime run by apocalyptic fanatics...
...planet is 4,500,000,000 years old, and we've had nukes for exactly 61. No one knows the precise prospects for human extinction, but Feynman was a mathematical genius who knew how to calculate odds. If he were to watch us today about to let loose the agents of extinction, he'd call a halt to all bridge building...
...North African coast for that matter. The early adventurers who came to the Americas created the original melting pot. It's hard to imagine one particular race laying claim to the discovery of this place we call the Americas. We shouldn't even refer to the western hemisphere. A planet, after all, has no east or west...
...learning that climate disruptions feed off one another in accelerating spirals of destruction. Scientists fear we may be approaching the point of no return THE GREENHOUSE EFFECT Without the greenhouse effect, life on Earth would not be possible. Energy from the sun is absorbed by the planet and radiated back out as heat. Atmospheric gases like carbon dioxide trap that heat and keep it from leaking into space. That's what keeps us warm at night...
...humans pour ever increasing amounts of greenhouse gases into the atmosphere, more of the sun's heat gets trapped, and the planet gets a fever BURNING FOSSIL FUELS RELEASES CARBON FUELING THE FIRE The amount of carbon dioxide in the atmosphere is climbing fast. Most of it comes from burning fuels for energy--gasoline in cars or coal for electricity, for example. The U.S., with less than 5% of the world's population, produces one-quarter of all greenhouse gases BURNING FORESTS REDUCES OXYGEN AND INCREASES DROUGHT SPREADING THE PAIN Deforestation, through clear-cutting or burning, sows havoc far beyond...
