István Szapudi, an astronomer at the University of Hawaii Institute for Astronomy, has turned to essentially geoengineering a giant parasol, or what he calls, a "Tethered solar shield" to shield the Earth from a portion of the sun's energy.
Scientists such as Christopher Essex, emeritus professor of applied mathematics and physics at the University of Western Ontario and former director of its theoretical physics program, said carbon dioxide isn't the driver of Earth's warmer temperature and that such geoengineering measures are "Extraordinarily dangerous."
The Oxford Geoengineering Programme defines geoengineering as "The deliberate large-scale intervention in the Earth's natural systems to counteract climate change."
"Solar radiation management is a geoengineering approach that aims to reduce the amount of solar radiation absorbed by the Earth to mitigate the effects of climate change," Mr. Szapudi wrote in his report.
"Given what we know today and the known risks of climate change, a tethered sun shield near the L1 Lagrange point at 1.5 million kilometers from us would not present an obvious risk to Earth. The benefit is preventing and even reversing negative effects of climate change."
Who built his first computer climate model in the 1970s and was chairman of The Global Warming Policy Foundation's Academic Advisory Council, said part of the problem with a sun shield is that it looks at the climate from an engineering perspective instead of a scientific one.
"Our results show that solar geoengineering will not simply reverse climate change. Instead, it has the potential itself to induce novel changes in climate."
