Planetary Ruin

Wall Street Journal: The Environmental Protection Agency's carbon regulation putsch continues, but apparently abusing the clean-air laws of the 1970s to achieve goals Congress rejected isn't enough. Late last week, the EPA made an unprecedented move to punish Texas for being the one state with the temerity to challenge its methods. To wit, the EPA violated every tenet of administrative procedure to strip Texas of its authority to issue the air permits that are necessary for large power and industrial projects. This...

Washington Post: Many policymakers and business leaders have come to see the most basic method of slowing global warming- cutting carbon dioxide emissions through a binding treaty - as elusive for now. They are turning their attention instead toward a more achievable goal: curbing other greenhouse gases that are warming the planet. As the annual meeting of the United Nations Framework Convention on Climate Change kicked off Monday in Cancun, Mexico, with the aim of laying the groundwork for a future pact, many...

Pittsburgh Post-Gazette: A constellation of 508 red dots stretches across a wall map in the office of Bruce Nilles, one for every power plant now burning coal in the United States. It is his job to make these stars go dark, one by one. The director of the Sierra Club's Beyond Coal campaign is a skinny Wisconsinite who bikes to work at the environmental group's warren of offices in adjoining Capitol Hill townhouses. He has no illusions that America can stop burning coal tomorrow, or even 10 years from now, and still generate...

Standard Speaker: Veterans Day at my home was a quiet affair, filled mostly by long walks with the family dog - burning calories, not gasoline. But before the first trek at mid-morning, I read an article in the Burlington, Vt., paper about some Vermont Air National Guard airmen returning home from a lengthy TDY (temporary duty) assignment in Saudi Arabia. Those latter two words in the headline caught my attention because early on in my own career in the Air Force I served a three-month TDY in Riyadh, the Saudis'...

MOSCOW. May 29 (Interfax) – Russian President Vladimir Putin has cautioned against turning Europe into a “powder keg”, referring to Washington’s plans to deploy elements of its missile defense system in Europe.

“We consider it harmful and dangerous to turn Europe into a “powder keg” and to fill it with new kinds of weapons,” Putin told a news conference after talks with the Portuguese prime minister in Moscow.

“It creates new unneeded risks for the entire system of international and European relations,” he said.

A small-scale, regional nuclear war could disrupt the global climate for a decade or more, with environmental effects that could be devastating for everyone on Earth, researchers have concluded.

The scientists said about 40 countries possess enough plutonium or uranium to construct substantial nuclear arsenals. Setting off a Hiroshima-size weapon could cause as many direct fatalities as all of World War II.

 ”Considering the relatively small number and size of the weapons, the effects are surprisingly large,” said one of the researchers, Richard Turco of the University of California, Los Angeles.  “The potential devastation would be catastrophic and long term.”

The lingering effects could re-shape the environment in ways never conceived. In terms of climate, a nuclear blast could plunge temperatures across large swaths of the globe. “It would be the largest climate change in recorded human history,” Alan Robock, associate director of the Center for Environmental Prediction at Rutgers’ Cook College and another member of the research team.

The results will be presented here today during the annual meeting of American Geophysical Union.

Blast fatalities

In one study, scientists led by Owen “Brian” Toon of the University of Colorado, Boulder, analyzed potential fatalities based on current nuclear weapons inventories and population densities in large cities around the world.

His team focused on the black smoke generated by a nuclear blast and firestorms—intense and long-lasting fires that create and sustain their own wind systems. 

For a regional conflict, fatalities would range from 2.6 million to 16.7 million per country. “A small country is likely to direct its weapons against population centers to maximize damage and achieve the greatest advantage,” Toon said.

Chilled climate

With the information, Robock and colleagues generated a series of computer simulations of potential climate anomalies caused by a small-scale nuclear war.

“We looked at a scenario of a regional nuclear conflict say between India and Pakistan where each of them used 50 weapons on cities in the other country that would generate a lot of smoke,” Robock told LiveScience.

They discovered the smoke emissions would plunge temperatures by about 2 degrees Fahrenheit (1.25 degrees Celsius) over large areas of North America and Eurasia—areas far removed from the countries involved in the conflict.

Typically when sunlight travels through the atmosphere, some rays get absorbed by particles in the air, before reaching Earth’s surface. After a nuclear blast, however, loads of black smoke would settle into the upper atmosphere and absorb sunlight before it reaches our planet’s surface. Like a dark curtain pulled over large parts of the globe, the smoke would cause cool temperatures, darkness, less precipitation and even ozone depletion.

At the end of the 10 years, the simulated climate still hadn’t recovered. 

Global upshot

The study showed it doesn’t take much nuclear power to drive meteoric results. Whereas the scenarios presumed the countries involved would launch their entire nuclear arsenals, that total is just three-hundredths of a percent of the global arsenal.

Will the conclusions result in worldly changes? “We certainly hope there will be a political response because nuclear weapons are the most dangerous potential environmental danger to the planet. They’re much more dangerous than global warming,” Robock said.
