Tanker aircraft might spew sulphur dioxide aerosol in the high atmosphere above Earth's poles, according to scientists.
The research estimates that it would cost around $11 billion per year to reduce polar temperatures by 2 degrees Celsius.
However, there are downsides to this plan, and it is just a temporary fix at best for climate change.
Scientists continue to come up with novel ideas for keeping Earth's temperatures.
Stable in the face of the mounting danger posed by a warming globe.
Recently, a proposal has been introduced in Environmental Research Communications that proposes using high-altitude tanker aircraft.
