Earth’s poles: global warming: Scientists suggest ‘controversial’ plan to refreeze Earth’s poles. Details here

In what might seem like a last ditch effort to save the melting ice caps and fight global warming, scientists have suggested a gigantic and controversial solution. According to them, high-flying jets can be used to spray the upper layers of the atmosphere with microscopic aerosol particles. This would reflect sunlight and allow the ice sheets to cool and refreeze.


What is the proposed plan?


According to the detailed plan, 125 military jets with air-to-air tankers would be needed to release a microscopic cloud of sulfur dioxide. The altitude would be 43,000 feet and the necessary latitude is 60 degrees in both hemispheres. 13 tonnes of particles released in summer and spring would cool the Earth’s poles by 2 degrees Celsius.

A former UK scientist says the plan would refreeze the Earth’s poles and control global sea level rise.

Wake Smith, the scientist leading the study, said the suggestion would only treat one of the symptoms of climate change.

This would not provide an effective cure for the cause.


Why is the plan controversial?


A large number of flights would be required for the plan to work. They would release greenhouse gases into the upper layers of the atmosphere, where these gases are very harmful.

Sun protection can reduce crop yields.

A program of this magnitude would require international agreement, which is difficult.

What is the debate?

Researchers and scientists say the plan targets the Earth’s poles, where only 1% of the population lives. Additionally, the cost is expected to be £1 billion, far less than other modes of responding to climate change.

Scientists believe that efforts are needed to deal with melting ice caps, as it would benefit all of humanity.
