A "Brilliant" Cure for Global Warming!

OMG now why didn't I think of this?!!! It's brilliant in it's simplicity!

Dust Storms May be Causing Global Warming


Scientists have been studying dust storms now for decades. They have determined that these storms has contributed greatly to global warming and the drastic shrinking of the planet's polar ice caps. But are we talking about Earth? No, Mars!

Computer simulations similar to those used to predict weather here on Earth show that the bright, windblown dust and sand particles affects Mars’ albedo—the amount of sunlight reflected from the planet’s surface. The research, detailed in the April 5 issue of the journal Nature, suggests these albedo variations play an important role in the climate of Mars. It could also potentially explain how global dust storms are triggered on the red planet.

Shaun Saunders sent this in saying that this ties in well with other articles posted here earlier on similar subject matter.

The Sun May Be Causing Global Warming

Earth is heating up, but so are Mars, Pluto and other worlds in our solar system, leading some scientists to speculate that a change in the sun’s activity is the common thread linking all these baking events. Habibullo Abdussamatov, the head of space research at St. Petersburg's Pulkovo Astronomical Observatory in Russia, recently linked the attenuation of ice caps on Mars to fluctuations in the sun's output. Abdussamatov also blamed solar fluctuations for Earth’s current global warming trend. His initial comments were published online by National Geographic News. But Abdussamatov’s critics say the Red Planet’s recent thawing is more likely due to natural variations in the planet’s orbit and tilt. On Earth, these wobbles, known as, are thought to contribute to the onset and disappearance ice ages.

Space Sunshade Might Be Feasible In Global Warming Emergency

For the past year, Roger Angel, a University of Arizona Regents' Professor and one of the world's foremost minds in modern optics, has been looking at ways to cool the Earth in an emergency. He's been studying the practicality of deploying a space sunshade in a global warming crisis, a crisis where it becomes clear that Earth is unmistakably headed for disastrous climate change within a decade or two. The plan would be to launch a constellation of trillions of small free-flying spacecraft a million miles above Earth into an orbit aligned with the sun, called the L-1 orbit. The spacecraft would form a long, cylindrical cloud with a diameter about half that of Earth, and about 10 times longer. About 10 percent of the sunlight passing through the 60,000-mile length of the cloud, pointing lengthwise between the Earth and the sun, would be diverted away from our planet. The effect would be to uniformly reduce sunlight by about 2 percent over the entire planet, enough to balance the heating of a doubling of atmospheric carbon dioxide in Earth's atmosphere.

The Lagrange Points mark positions where the combined gravitational pull of the two large masses provides precisely the centripetal force required to rotate with them. They are analogous to geosynchronous orbits in that they allow an object to be in a "fixed" position in space rather than an orbit in which its relative position changes continuously.
