"A fleet of roughly 125 tankers could return subpolar regions close to pre-industrial temperatures"
Scientists presented a controversial plan whereby high-flying jets similar to a modified American KC-135R could spray microscopic aerosol particles into the atmosphere to refreeze the North and South Poles. The recently published research in IOP's Environmental Research Communications suggests that the method would be feasible and fairly cheap.
The plan, which falls under a controversial climate intervention technology called Stratospheric aerosol injection (SAI), would target only subpolar regions- instead of having a global intervention that most other SIA operations assume, highlights the paper.
For the southern hemisphere, it's a little more complicated. 60 degrees of the south pole touches nowhere on land and is inhabitable. The closest significant airfields are in Chile and Argentina at the southern tip of Patagonia. Read more:

Last summer, the Intergovernmental Panel on Climate Change (IPCC) issued a barn burner of a report laying out an unpleasant reality: Cutting CO2 emissions is no longer enough—countries also need to capture CO2 and store it away. Historically, the United States has been late to the party when it comes to implementing IPCC recommendations, but when the report dropped, the United States was already in the early stages of a very specific boom in carbon capture infrastructure—specifically, new pipelines that would carry captured CO2.
