Could refreezing the north and south poles reverse global warming?



Global warming can be reversed by refreezing the poles, according to new research.

Blocking the sun would restore Earth's ice 'caps' at the north and south - maintaining weather systems.

The ambitious idea sounds like a crazy plot from a sci-fi blockbuster - but it is "both feasible and remarkably cheap," researchers claim.


Aircraft would fly over the Arctic and Antarctic spraying particles - known as a stratospheric aerosol injection (SAI).

They combat greenhouse gases by dimming starlight - cooling the whole planet, say the US team.

The first author Professor Wake Smith, of Yale University: "It would seek to abate climate change by deflecting back into space a small fraction of the incoming solar radiation."

The study found it would only have to be done in the sub-polar regions. Previous proposals have suggested using the technique across the planet.

It would quickly envelop the poles and may arrest or reverse ice and permafrost melt at high latitudes - stopping sea level rise..
