Artificial Cooling Of The Earth

Spray aerosols high up in the stratosphere? Paint roof and plant light-colored crops? Brighten clouds with sea water? How about positioning "sun shades" over the earth?

While thinking deeply over global warming, a group of scientists, philosophers, and legal scholars observed whether the human intervention could artificially cool the Earth. When it comes to global warming some scientists are thinking out of the box.

Methods of Artificial Cooling of the Earth

Some of the ideas include

• Constructing a sun-shield and reflecting the sun rays to prevent them from reaching the earth.

• Spraying huge amounts of sulfur dioxide into the atmosphere, this chemical would reflect the sun's light, cooling the planet.

• Using asteroid dust to block the sun's light

• Assembling a giant, translucent glass disk at the point where the gravitational pull of the earth and the sun are felt in roughly equal measure, which would cover an area roughly the size of India, would reflect some of the sun's rays away from the earth.

• Cover the Arctic Ocean with bits of white plastic that will float on the surface of the water and reflect the sun's light into space.

Effects

A document released at the UN climate conference after examining the present day scenario said that reflecting a small amount of sunlight back into space before it strikes the Earth's surface would return to levels 250 years ago before the industrial revolution began dumping CO2 into the air trapping the heat and causing temperatures to rise. Scientists feel anxious about injecting sulfur dioxide into the upper atmosphere could put some regions at risk. Some scientist's say that they can't put their ideas to test as the Earth cannot be trusted. Well, it is not the planet that can't be trusted but we humans.

Many Geoengineering researchers tell that climate manipulation could have a devasting effect on some regions. It is a highly risky strategy where one region could be benefitted, destroying the others. Injecting aerosols in the northern hemisphere will reduce the cyclone activity. Such artificial cooling techniques may even lead to tumultuous storms as well as drought-prone areas which would lead to adverse effects. This would even lead to major consequences like less rainfall and more fire due to the sudden stoppage of the release of greenhouse gases which would heat up things very quickly.

Implementation

These solutions aren't cheap or easy but they could help hold off warming even if we do not cut our greenhouse gas emissions. So buy a hybrid car now and hope for a gigantic solar umbrella later-but don't count on it.
