In an article published in the journal Nature, three scientists  have called for governments to fund a massive research effort in ways to  shield the planet from solar radiation as a way to stave off global  warming.
"The idea of deliberately manipulating Earth's energy  balance to offset human-driven climate change strikes many as dangerous  hubris," wrote David Keith of the University of Calgary, Canada, Edward  Parson of the University of Michigan and Granger Morgan of Carnegie  Mellon University.
"Many scientists have argued against research  on solar radiation management, saying that developing the capability to  perform such tasks will reduce the political will to lower greenhouse  gas emissions. We think that the risks of not doing research outweigh  the risks of doing it."
The practice of "geoengineering" consists  of finding ways to limit the amount of solar radiation reaching the  earth, thus slowing the rate of planetary warming. Suggested methods  include simulating a massive volcanic eruption by generating sulphate  aerosols high in the atmosphere, or spraying tiny seawater droplets to  create low clouds over the ocean. Although the subject was considered  fringe only a few years ago, scientific interest in geoengineering is on  the rise.
