Scientists have come up with a radical new way in which to help reduce the effects of global warming.
[!gad]Few topics have been discussed as much or have generated as much controversy as climate change. With global temperatures set to soar within the next 100 years, scientists have been looking for more effective solutions to tackle the global warming crisis. Now researchers in Scotland have come up with a novel new idea for a way to reduce the amount of sunlight hitting the Earth - a giant dust cloud generated by an asteroid in space.
The technique would involve installing a device on to a near-Earth asteroid that would hurl material out in to space and create a vast cloud of dust, blotting out the Sun. Scientists have openly admitted however that the concept would not only prove risky but that there would be no way to properly test the concept before going ahead with it.
The researchers calculate that the largest near-Earth asteroid, 1036 Ganymed, could maintain a dust cloud large enough to block out 6. 58 percent of the solar radiation that would normally reach Earth, more than enough to combat any current global warming trends.
