Scientists are considering the possibility of climate engineering via aerosol injection
In a new paper published in Environmental Research Letters [open, DOI: 10.1088/1748-9326/aae98d] researchers discuss the potential to use what is known as stratospheric aerosol injection (or SAI) to help cool the Earth over a long period of time. This "solar geoengineering" effort would take a long time to plan and put into action, but the authors of the work suggest that it is indeed possible.
"While we don't make any judgement about the desirability of SAI, we do show that a hypothetical deployment program starting 15 years from now, while both highly uncertain and ambitious, would be technically possible strictly from an engineering perspective," Dr. Gernot Wagner of Harvard said in a statement. "It would also be remarkably inexpensive, at an average of around $2 to 2.5 billion per year over the first 15 years."

Not to mention that if Professor Zharkova is even close to correct, we're going to have a rude surprise here in the next decade or so, and will need all the warming we can muster. Cold equals crop failure, and this time around we've got WAY more mouths to feed.

And there is no Alkibiades to come back and save us from ourselves.
