A Quote by Paul J. Crutzen

In discussing the state of the atmosphere following a nuclear exchange, we point especially to the effects of the many fires that would be ignited by the thousands of nuclear explosions in cities, forests, agricultural fields, and oil and gas fields. As a result of these fires, the loading of the atmosphere with strongly light absorbing particles in the submicron size range (1 micron = 10-6 m) would increase so much that at noon solar radiation at the ground would be reduced by at least a factor of two and possibly a factor of greater than one hundred.

If Earth ever suffers a runaway greenhouse effect (like what has happened on Venus), then our atmosphere would trap excess amounts of solar energy, the air temperature would rise, and the oceans would swiftly evaporate into the atmosphere as they sustained a rolling boil. This would be bad.

Neil deGrasse Tyson

Mars does not have an atmosphere and does not have a magnetic field today, so the planet doesn't have the protection from radiation that our atmosphere and magnetic fields provide us on Earth.

David Grinspoon

The industrialization of China alone would increase by 90 percent the concentration of CO2 in our atmosphere and would at least increase the atmospheric CO2 by at least another 100 parts per million.

John Olver

Global warming results not from the emission of greenhouse gases into the atmosphere, but from an unusually high level of solar radiation and a lengthy - almost throughout the last century - growth in its intensity. It is no secret that when they go up, temperatures in the world's oceans trigger the emission of large amounts of carbon dioxide into the atmosphere. So the common view that man's industrial activity is a deciding factor in global warming has emerged from a misinterpretation of cause and effect relations.

Sooner or later there will be a nuclear 9/11 [by Islamic terrorists] in an American city or that of a US ally... A terrorist nuclear attack against an American city could take many forms. A worst case scenario would be the detonation of a nuclear device within a city. Depending upon the size and sophistication of the weapon, it could kill hundreds of thousands or even millions of people.

David Krieger

So, there's quite a big keep-out zone, and when you factor the keep-out zone into account, the solar panels put on that area would typically generate more power than that nuclear power plant.

Elon Musk

A full scale nuclear exchange, lasting less than 60 minutes...could wipe out more than 300 million Americans, Europeans, and Russians, as well as untold numbers elsewhere. And the survivors-as Chairman Khrushchev warned the Communist Chinese, `the survivors would envy the dead.' For they would inherit a world so devastated by explosions and poison and fire that today we cannot conceive of its horrors.

John F. Kennedy

I think Pakistan was not a factor in terms of decision India to obtain nuclear weapon. Because there was no talk of Pakistan having any capability. The main factor was China. And the international prestige that China was getting as a consequence of having its own nuclear weapons.

Subramanian Swamy

I think if terrorists had nuclear materials and found people to put a bomb together - both of which are possible - we would already have seen a nuclear explosion. But we have literally thousands of people around the world working their tails off and making a lot of sacrifices to contain nuclear materials. I particularly would like to compliment the Russians on this. In times of great economic distress, many of them could have made an awful lot of money if they had sold their expertise.

Sam Nunn

Fracking is an amazing instance of discovery of many things that come together to make it much cheaper to extract oil and gas. In a world where burning oil and gas puts more and more carbon into the atmosphere, it's not actually the most important kind of innovation to have.

Paul Romer

Looking back, I underestimated the risks. The planet and the atmosphere seem to be absorbing less carbon than we expected, and emissions are rising pretty strongly. Some of the effects are coming through more quickly than we thought then.

Nicholas Stern

There has been a transition from a nuclear-annihilation scenario to an isolated-terrorist-nuclear-bomb scenario. But we're still locked into a mind-set that nuclear war would be so overwhelming that any kind of preparedness would be futile.

Irwin Redlener

The alternative, no limits on Iran's nuclear program, no inspections, an Iran that's closer to a nuclear weapon, the risk of regional nuclear arms race, and the greater risk of war - all that would endanger our [American] security.

Barack Obama

Not everyone agrees the bears should be protected. Hunters, oil interests, even the state of Alaska has questions about the effects protection would have on oil and gas exploration and commercial shipping. But for many others, the bears are a symbol of a bigger crisis threatening the planet.

Sam Champion

Let the rabbit of free enterprise out of its velveteen bag and too many people would have to be fired, too much idiocy exposed to the light of judgment or ridicule, too much vanity sacrificed to the fires of efficiency. Such a catastrophe obviously would threaten the American way of life, to say nothing of the belief in free markets.

Lewis H. Lapham

There's no question that Saddam Hussein is a threat Yes, he has chemical and biological weapons. He's had those for a long time. But the United States right now is on a very much different defensive posture than we were before September 11th of 2001 He is, as far as we know, actively pursuing nuclear capabilities, though he doesn't have nuclear warheads yet. If he were to acquire nuclear weapons, I think our friends in the region would face greatly increased risks as would we.
