Re-freezing the Poles

Author: EIS Release Date: Sep 23, 2022

Researchers at Yale have proposed a way to re-freeze the North and South Poles.

 

 Aircraft flying at 43,000  feet could spray microscopic aerosol particles into the atmosphere at latitudes of 60 degrees north and south.

 

The particles would slowly drift poleward, slightly shading the surface beneath which  would allow the melting poles to refreeze, solving the problems of melting glacial ice and rising sea levels. 

 

The technique would ‘abate climate change by deflecting back into space a small fraction of the incoming solar radiation’, the scientists say. 

 

The concept, lead by Yale lecturer Wake Smith, is called stratospheric aerosol injection (SAI). It would cost a $11 billion a year – but the researchers say this would be cheaper than other climate mitigation methods.
