  • Earth Day

    We live in a vast universe made up of billions of galaxies, each of which is made up of billions of stars.  Our home is a small planet that revolves around a small sun in a remote galaxy.  It is just the right distance from the sun that it is not too hot and not too cold to support life.  It has air that is breathable, water that is drinkable, and topsoil suitable for growing crops.  In the immensity of space, it is a very small dot, what astrophysicist Carl Sagan referred to as a “pale blue dot.”  Our Earth is the only place we know of that harbors life.  It is precious beyond any riches that could be imagined. 


    One would think that any sane, self-reflecting creatures that lived on this planet would recognize its beauty and preciousness and would want to tend to it with care.  In Antoine de Saint-Exupéry’s classic book, The Little Prince, the prince says, “It’s a matter of discipline.  When you’ve finished washing and dressing each morning, you must tend to your planet.”  But that is an imaginary planet with an imaginary little prince.  On the real planet that supports life, the one we inhabit, there aren’t enough of us who exercise such discipline and tend to our planet with loving care.


    Think about how we have managed our planet.  We have allowed the planet to become divided into rich and poor, where a few people have billions of dollars and billions of people have few dollars.  While some live in greed, the majority live in need.  We have parceled the planet into entities we call countries and created borders that countries try to protect.  We have created military forces in these countries and given them enormous resources to prepare for war and to engage in war.  Annual global military expenditures now exceed $1.6 trillion, while hundreds of millions of humans live without clean water, adequate nutrition, medical care and education.


    We have eagerly exploited the planet’s resources with little concern for future generations or for the damage we cause to the environment.  Instead of using renewable energy from the sun to provide our energy needs, we exploit the Earth’s stores of oil and transport them across the globe.  We have turned much of the world into desert.  We have polluted the air we breathe and the water we drink.  In our excess, we have pushed the planet toward the point of no return in global warming, and then argued global warming as a reason to build more nuclear power plants.


    We keep relearning in tragic ways that we humans are fallible creatures.  That is the lesson of our recurrent oil spills.  It is also the lesson of the accidents at Chernobyl a quarter century ago and at Fukushima one year ago.  It is a lesson that we urgently need to learn about nuclear weapons – weapons we have come close to accidentally using on many occasions and have twice used intentionally. 


    Nuclear weapons kill directly by blast, fire and radiation.  The nuclear weapons used at Hiroshima and Nagasaki were small in comparison with today’s thermonuclear weapons.  In recent years, we have learned some new things about nuclear war.  Atmospheric scientists have modeled a hypothetical nuclear war between India and Pakistan in which each side uses 50 Hiroshima-size nuclear weapons on the other side’s cities.  In addition to the direct effects of the weapons, there would be significant indirect effects on the environment.  Smoke from the burning cities would rise into the stratosphere and reduce warming sunlight for ten years, which would lower average surface temperatures, reduce growing seasons and lead to global famine that could kill hundreds of millions of people. 


    That would be the result of a small nuclear war, using less than one percent of the operationally deployed nuclear weapons on the planet.  A nuclear war between the US and Russia could lead to the extinction of most or all complex life on Earth, including human life.  As we celebrate Earth Day this year, 20 years after the end of the Cold War, both the US and Russia maintain hundreds of launch-ready, land-based inter-continental ballistic missiles on high-alert status, ready to be fired in moments.


    We who are alive today are the trustees of this planet for future generations.  We’re failing in our responsibility to pass it on intact.  We need a new Earth ethic that embraces our responsibility for fairness to each other and to the future.  We need new ways of educating that do not simply accept the status quo.  We need to trade in our patriotism for a global humatriotism.  We need a new approach to economics based on what is truly precious – life and the conditions that support it. 


    Earth Day will have its greatest value if it reminds us to care for our Earth and each other all the other days of the year, individually and through our public policy.  We need to inspire people throughout the world, young and old alike, with a vision of the beauty and wonder of the Earth that we can now enjoy, restore and preserve for future generations if we tend to our planet with the discipline of the little prince. 

  • For Nuclear Security Beyond Seoul, Eradicate Land-Based ‘Doomsday’ Missiles

    This article was originally published by the Christian Science Monitor.

    David KriegerPresident Obama and other world leaders gathered at the Nuclear Security Summit in Seoul, South Korea, this week to address threats posed by unsecured nuclear material. If Mr. Obama is truly concerned about nuclear safety, he should seriously consider doing away with the 450 inter-continental ballistic missiles deployed and ready to fire at Russia on a moment’s notice.

    Last month we were among 15 protesters who were arrested in the middle of the night at Vandenberg Air Force Base, some 70 miles north of Santa Barbara, Calif. We were protesting the imminent test flight of a Minuteman III inter-continental ballistic missile.

    The Air Force rationale for doing these tests is to ensure the reliability of the US nuclear deterrent force; but launch-ready land-based nuclear-armed ballistic missiles are the opposite of a deterrent to attack. In fact, their very deployment has the potential to launch World War III and precipitate human extinction – as a result of a false alarm.

    We’re not exaggerating. Here’s why: These nuclear missiles are first-strike weapons – most of them would not survive a nuclear attack. In the event of a warning of a Russian nuclear attack, there would be an incentive to launch all 450 of these Minuteman missiles before the incoming enemy warheads could destroy them in their silos.

    If the warning turned out to be false (there have been many false warnings), and the US missiles were launched before the error was detected, World War III would be underway. The Russians have the same incentive to launch their land-based missiles upon warning of a perceived attack.

    Both US and Russian land-based missiles remain constantly on high-alert status, ready to be launched within minutes. Because of the 30-minute flight times of these missiles, the presidents of both the US and Russia would have only approximately 12 minutes to decide whether to launch their missiles when presented by their military leaders with information indicating an imminent attack (after lower-level threat assessment conferences).

    That’s only 12 minutes or less for the president to decide whether to launch global nuclear war.  While this scenario is unlikely, it is definitely possible: Presidents have repeatedly rehearsed it, and it cannot be ruled out due to the graveness of its potential consequences.

    Russia came close to launching its missiles based on a warning that came Jan. 25, 1995. President Yeltsin was awakened in the middle of the night and told a US missile was headed toward Moscow. Fortunately, Yeltsin was sober and took longer than the time allocated for his decision on whether to launch Russian nuclear-armed missiles in response.

    In the extended time, it became clear that the missile was a weather sounding rocket from Norway and not a US missile headed toward Moscow. Disaster was only narrowly averted.

    Here is the really compelling part of the story: If all 450 US land-based Minuteman III missiles with thermonuclear warheads were ever launched at Russia – with many of the targets in or near cities, as now planned – most Americans would die as a result, along with most of humanity.  Our own weapons would contribute as much or more to these deaths in America and the rest of the globe as any Russian warheads launched.

    This is because smoke from the enormous nuclear firestorms created by even a “successful” US nuclear first-strike would cause catastrophic disruption of global climate and massive destruction of the Earth’s protective ozone layer, leading to global famine.

    Recent peer-reviewed studies, done by atmospheric scientists Alan Robock (Rutgers), Brian Toon (University of Colorado-Boulder), Richard Turco (UCLA) and colleagues, predict that such an attack would create immense firestorms that would quickly surround the planet with a dense stratospheric smoke layer.

    The black smoke would be heated by the sun, lofted like a hot air balloon, and would remain in the stratosphere for at least 10 years. There it would block and prevent a large fraction of sunlight from reaching the Earth’s surface. The sharp reduction of warming sunlight would rapidly produce global Ice Age weather conditions. This would eliminate or dramatically reduce growing seasons for a decade and would likely cause the starvation of most or all humans.

    Along with other effects – including prolonged destruction of the ozone layer – most complex life on Earth could be destroyed. Scientists say the process would be similar to when an asteroid hit the Earth some 65 million years ago, raising a global dust cloud that reduced sunlight, lowering temperatures and killing vegetation. That caused the extinction of the dinosaurs and 70 percent of the Earth’s species.

    The cause of extinction in our case would not be an external, celestial event, but rather the launching of thermonuclear weapons we had created by our own cleverness, supposedly for our own security.

    The Minuteman III missile tests from Vandenberg Air Force Base are thus really tests of an American Nuclear Doomsday Machine.

    Nuclear weapons do not make the US or the world more secure. In particular, the Minuteman III missiles – land-based, vulnerable, on high alert, and susceptible to being triggered by a false alarm – make us less secure. Anyone who cares about humankind having a future should protest these tests and call for the elimination of all nuclear-armed inter-continental ballistic missiles as an initial step toward the total abolition of nuclear weapons.

    If the US did away now with its nuclear-armed land-based missile force, it would still have 288 invulnerable submarine-launched ballistic missiles (armed with approximately 1,152 warheads) to act as a retaliatory threat to nuclear attack. But it would no longer have tempting targets for the Russians to strike preemptively in a time of tension or in the event of a false warning of attack.

    It would still be imperative to reduce US (and Russian) total warheads to levels that do not threaten the possibility of causing human extinction.

    And even the smaller existing nuclear arsenals of India and Pakistan threaten global disaster. Professor Robock and his colleagues have estimated that in a nuclear exchange between India and Pakistan in which each side used 50 Hiroshima-size bombs (each side now has more than that number), the smoke rising into the stratosphere could cause a global reduction of sunlight and destruction of ozone leading to crop failures and global famine.

    By comparison, the launch-ready thermonuclear forces of the US and Russia contain roughly 500 times the explosive power of the 100 atomic bombs of India and Pakistan.

    Now is the time for the people and nations of the world to stand up against the potential extinction of the human species and demand that political leaders pursue the path to zero nuclear weapons, a path mandated by the terms of the Nuclear Non-Proliferation Treaty and the International Court of Justice. Until then, protest and civil resistance will be necessary.

    We should seek two principal goals: first, a commitment by the existing nuclear weapon states to forego launch-on-warning and first use of nuclear weapons under any circumstances; and second, good faith negotiations for a new treaty for the phased, verifiable, irreversible, and transparent elimination of nuclear weapons.

    It is our hope that by committing nonviolent civil resistance, being arrested, going to federal court, and explaining our actions to the public, we will help to awaken and engage the American people on this issue of utmost importance to our common future.

  • Preventing an Accidental Nuclear Winter

    Nuclear Winter

    In a study made by the World Health Organization, they found that a nuclear war between the U.S. and Russia could kill one billion people outright. In addition, it could produce a Nuclear Winter that would probably kill an additional one billion people. It is possible that more than two billion people, one-third of all the humans on Earth would be destroyed almost immediately in the aftermath of a global thermonuclear war. The rest of humanity would be reduced to prolonged agony and barbarism. These findings are from a study chaired by Sune K. Bergstrom (the 1982 Nobel laureate in physiology and medicine) nearly 20 years ago. (1)

    Subsequent studies have had similar findings. Professor Alan Robock says, “Everything from purely mathematical models to forest fire studies shows that even a small nuclear war would devastate the earth.” (2)

    Rich Small’s work, financed by the Defense Nuclear Agency, suggests that burning cities would produce a particularly troublesome variety of smoke. The smoke of forest fires is bad enough. But the industrial targets of cities are likely to produce a rolling, black smoke, a denser shield against incoming sunlight. (3)

    Nuclear explosions can produce heat intensities of 3,000 to 4,000 degrees Centigrade at ground zero. Nuclear explosions can also lift an enormous quantity of fine soil particles into the atmosphere, creating more than l00,000 tons of fine, dense, radioactive dust for every megaton exploded on the surface. (4) The late Dr. Carl Sagan said the super heating of vast quantities of atmospheric dust and soot will cover both hemispheres. (5) For those who survive a nuclear attack, it would mean living on a cold, dark, chaotic, radioactive planet.

    A nuclear warhead is far more destructive than is generally realized. For example, just one average size U.S. strategic 250 Kt nuclear warhead has an explosive force equal to 250,000 tons of dynamite or 50,000 World War II type bombers each carrying 5 tons of bombs. The truck bombs that terrorists exploded at the New York World Trade Center and in Oklahoma City each had an explosive force equal to about 5 tons of dynamite. (6)

    Accidental Nuclear War

    The U.S. and Russia each have more than 2,000 strategic nuclear warheads set for hair-trigger release. If launched they could be delivered to targets around the world in 30 minutes. They would have an explosive force equal to l00,000 Hiroshima size bombs. (7) Russia and the U.S. have more than 90 percent of the nuclear weapons in the world. The more automated and shorter the decision process becomes the greater is the possibility of missiles being launched to false warnings.

    The U.S. is trying to decide whether to build an anti-missile “star wars” defense or not. In order for an anti-ballistic missile to hit another missile traveling at incredible speed that can come from many different directions, it would be necessary to have a very complex computerized system.

    President Reagan’s Defense Secretary, Casper Weinberger, said that since an anti-missile defense would require decisions within seconds, completely autonomous computer control is a foregone conclusion. There would be no time for screening out false alarms and a decision to launch would have to be automated—there would be no time for White House approval. (8)

    A highly automated defense system that has no time for determining whether a warning is false or not is highly likely to launch to a false warning. There are always false warnings. For example, during 1981, 1982 and 1983 there were 186, 218 and 255 false alarms, respectively, in the U.S. strategic warning system. (9)

    There have been at least three times in the last 20 years that the U.S. and Russia almost launched to false warnings. Fortunately there was enough time to determine that the warnings were false before decision time ran out.

    In 1979, a U.S. training tape showing a massive attack was accidentally played.

    In 1983, a Soviet satellite mistakenly signaled the launch of a U.S. missile.

    In 1995, Russia almost launched its missiles because of a Norwegian rocket studying the northern lights. (l0)

    If the U.S. builds an anti-missile defense it appears certain that missiles would be launched to false warnings because no time is available for determining whether a warning is false or not.

    Preventive Action Needed

    Plans to build an anti-missile defense need to be carefully researched as to how it could increase the danger of an accidental nuclear war. As the research progresses, the findings need to be widely discussed in the news media. The more widely and clearly the danger is made known the more concerned the public should be for agreements to greatly reduce and eventually eliminate all nuclear weapons from the world.

    As humanity’s safety becomes more and more dependent upon technology, the technological dangers need to be guarded against. Technical errors in one system may trigger errors in others. When researching missile defense dangers the following types of factors need to be included in the assessments, e.g. Electromagnetic Pulse (EMP)), “Dead Hand” control of missiles, High Frequency Active Auroral Research Program (HAARP), Hazards of Electromagnetic Radiation to Ordnance (HERO). Russia’s blind spots in its satellite warning system also need to be included in this research.

    The U.S. and Russia are in a position where either can destroy humanity in a flash and yet there appears to be little recognition of this peril hanging over the world. Only 71 out of 435 U.S. congressional representatives signed a motion calling for nuclear weapons to be taken off of hair-trigger alert. (11) The U.S. Senate rejected the Comprehensive Test Ban Treaty in 1999. (12)

    Queen Noor al Hussein, of Jordan, said “The sheer folly of trying to defend a nation by destroying all life on the planet must be apparent to anyone capable of rational thought.” (13) There is a need to greatly increase public awareness of the danger in order to provide broad, long-term understanding and support for arms agreements ridding the world of nuclear weapons.
