London: Chemicals pollinating sun lowering expensive eye & # 39; above the World to reduce global warming can be "remarkably lower", and cost about $ 3.1 billion a year over & # 39; 15 years, according to a study by American scientists.

A new way to reduce climate change? Blocked the sun.

Some researchers say that the technique of geo known as stratospheric aerosol injection engineering (SAI) can & # 39; to limit rising temperatures are causing climate change.

S & # 39; yet, unproven and hypothetical, it involves the use of & # 39; big pipes, gun or aircraft specially designed to spray large quantities of & # 39; sulphate particles in the layer & # 39; on the atmosphere to act as a barrier to reflect against the sunlight.

The total costs for the launch of & # 39; & # 39 hypothetical effort; the SAI 15 years from now of & # 39; $ A4.8 billion, scientists at the University & # 39; Harvard said in & # 39; report published in the journal Letters & # 39; Environmental Research, Adding that the average & # 39; annual operating costs would & # 39; about $ 3.1 billion a year over 15 years.
