Asteroids - way to fight warming?

A radical way to combat global warming came up with Scottish scientists. They propose that the close of the sunlight falling on the earth giant cloud of dust. This dust can be obtained from asteroid if combined with a solenoid top. He will chop up, spew a jet of dust and also mention that the asteroid is moving towards the required point.Dust cloud should be placed in the so-called Lagrange points, the line between the Sun and the Earth, where the force of gravity offset each other. Creating a giant dust cloud will require effort and resources, says astrophysicist Sternberg Astronomical Institute Vladimir Muffler:- In order to disperse the particles and the amount of such a closed country, you need a pretty massive asteroid. Care should crash and this substance spread over an area of ​​many thousand square kilometers. Costs for the project will be colossal.

Scottish forecasts indicate climate: temperature in the world will increase by the end of the century almost 6.5 degrees. If the Lagrange point switch asteroid 32 kilometers in diameter Ganymede, it will keep a large cloud of dust that can close 7% sunlight. This will compensate for global warming. But moving such large cosmic bodies far impossible. In addition, you will learn to fear the cloud of dust can lead to the most unexpected consequences for the Earth. Astrophysicist tells the Astronomical Institute RAN Dmitry Vibe.- It would be more to look at this idea climatologists. Cloud of dust will reduce the level of solar radiation, the temperature will fall to the ground, what we dream. We are therefore very happy, and she will continue to fall further. And how much will be good at it to have uncontrollable dust cloud, is not known. It may turn out to be far more dangerous than uncontrolled asteroid.Better yet does not break the asteroids, but terrestrial climate control methods. Among other things, withdraw from burning carbon fuels, consider astrophysicist Vladimir muffler. Now humanity gradually moves to the environmentally clean energy sources - wind, tide, solar energy. They have enough for our civilization. Smao should learn to use them efficiently. Scots ideas are nice, but not feasible, summarizes scientist.
