Could A Small Nuclear War Reverse Global Warming?



Nuclear war is a bad thing.

Right?

Scientists from NASA and a number of other institutions have recently been modeling the effects of a war involving a hundred Hiroshima-level bombs, or 0.03 percent of the world's current nuclear arsenal, according to National Geographic. The research suggests five million metric tons of black carbon would be swept up into the lowest portion of the atmosphere.

The result, according to NASA climate models, could actually be global cooling.

From National Geographic:

    In NASA climate models, this carbon then absorbed solar heat and, like a hot-air balloon, quickly lofted even higher, where the soot would take much longer to clear from the sky.

While the global cooling caused by superpower-on-superpower war could be catastrophic (hence the term "nuclear winter") a small scale war could have an impact on the world climate, says National Geographic. Models suggest that though the world is currently in a warming trend, small-scale war could lower global temperatures 2.25 degrees F for two-to-three years following war.

In more tropical areas temperatures could fall 5.4 to 7.2 degrees F.

But the likelihood of disaster over reversing global warming is a more imminent concern, according to TIME.

From TIME:

    ...even a small exchange of nuclear weapons--between 50-100 Hiroshima-sized bombs, which India and Pakistan already have their in arsenal--would produce enough soot and smoke to block out sunlight, cool the planet, and produce climate change unprecedented in recorded human history.

In addition, the extreme weather caused by even a mild nuclear winter would have a tremendous effect on crops and famines, including creating a 10 percent global decrease in precipitation, according to National Geographic. The soot could also cause tremendous harm to the ozone layer, allowing more ultraviolet rays to reach Earth.

The cons seem to outweigh the pros in the event of global cooling caused by even a small nuclear war.

THERE IS NO GLOBAL WARMING BEING CAUSED BY HUMANITY.  GLOBAL WARMING IS CAUSED BY SUNSPOTS AND THE TEMPERATURES RISE AND FALL ACCORDINGLY.

IT WAS A SCHEME PLANNED OUT BY THE BILDERBERG GROUP AND THE CLUB OF ROME TO IMPLEMENT CARBON TAXES TO FUND A WORLD BANK !!!!!!!

UNDER NO CIRCUMSTANCES SHOULD YOU EVER HAVE A NUCLEAR WAR.  MARS HAD ONE IN 10,000 BC +/- AND IT IS STILL IN RECOVERY TODAY.

NASA GETS THEIR FUNDING BY THE SAME EUGENICISTS THAT RUN THE FEDERAL-RESERVE.  SO OF COURSE THEY ARE GOING TO PUT FORTH THESE INSANE SCENERIOS.

DON'T GET SUCKERED PEOPLE !!!!!!!!!!!!!!!

So you never saw this study, I take it?

Study acquits sun of climate change
POSTED: 11:39 a.m. EDT, September 15, 2006


OSLO, Norway (Reuters) -- The sun's energy output has barely varied over the past 1,000 years, raising chances that global warming has human rather than celestial causes, a study showed on Wednesday.

Researchers from Germany, Switzerland and the United States found that the sun's brightness varied by only 0.07 percent over 11-year sunspot cycles, far too little to account for the rise in temperatures since the Industrial Revolution.

"Our results imply that over the past century climate change due to human influences must far outweigh the effects of changes in the sun's brightness," said Tom Wigley of the U.S. National Center for Atmospheric Research.

Most experts say emissions of greenhouse gases, mainly from burning fossil fuels in power plants, factories and cars, are the main cause of a 0.6 Celsius (1.1 Fahrenheit) rise in temperatures over the past century.

A dwindling group of scientists says that the dominant cause of warming is a natural variation in the climate system, or a gradual rise in the sun's energy output.

"The solar contribution to warming over the past 30 years is negligible," the researchers wrote in the journal Nature of evidence about the sun from satellite observations since 1978.

They also found little sign of solar warming or cooling when they checked telescope observations of sunspots against temperature records going back to the 17th century.

They then checked more ancient evidence of rare isotopes and temperatures trapped in sea sediments and Greenland and Antarctic ice and also found no dramatic shifts in solar energy output for at least the past millennium.

"This basically rules out the sun as the cause of global warming," Henk Spruit, a co-author of the report from the Max Planck Institute in Germany, told Reuters.

Many scientists say greenhouse gases might push up world temperatures by perhaps another 3 Celsius by 2100, causing more droughts, floods, disease and rising global sea levels.

Spruit said a "Little Ice Age" around the 17th century, when London's Thames River froze, seemed limited mainly to western Europe and so was not a planet-wide cooling that might have implied a dimmer sun.

And global Ice Ages, like the last one which ended about 10,000 years ago, seem linked to cyclical shifts in the earth's orbit around the sun rather than to changes in solar output.

"Overall, we can find no evidence for solar luminosity variations of sufficient amplitude to drive significant climate variations on centennial, millennial or even million-year timescales," the report said.

Solar activity is now around a low on the 11-year cycle after a 2000 peak, when bright spots called faculae emit more heat and outweigh the heat-plugging effect of dark sunspots. Both faculae and dark sunspots are most common at the peaks.

Still, the report also said there could be other, more subtle solar effects on the climate, such as from cosmic rays or ultraviolet radiation. It said they would be hard to detect.

Mars has a CO2 rich atmosphere and it has 20-30 degree winters and 80-90 degree summers at its equator much like Earth.

There's a universal gas formula where PV = n R T  where P is pressure, V is volume, n is the number of mols in the gas used, R is a universal gas constant, and T is tempurature.

Each gas expands and compresses at different rates but they all fit the formula.

If Venus were to have the 800 F degree temperatures in their atmosphere like NASA claims the planet would have to be 250 times the size of the Earth.

This crap is spewed by scientists who have eugenicists funding their research.
