#Stratospheric aerosol injection (SAI) is a solar #geoengineering strategy intended to cool the Earth by dispersing highly reflective aerosols into the stratosphere, mimicking the natural cooling effects of volcanic eruptions. Recent studies evaluated synthetic #diamond dust as a potentially safer alternative to environmentally damaging sulfate aerosols.

Diamonds are not a geoengineer’s best friend

By disproving the viability of a massive "diamond shield," climate scientists can now efficiently redirect computational modeling

And yeah, what this article doesn't mention is that changes in polar atmospheric circulation is due to #ClimateChange (link to study in comments)...

A #Stratospheric Warming event will Engulf the southern #PolarVortex, with possible far reaching Weather impacts

"A stratospheric warming event is about to unfold over the Southern Hemisphere, which is currently in its Winter season. The latest forecasts show strong temperature and pressure waves in the Stratosphere above the South Pole. These events are rare in the Southern Hemisphere but are usually very powerful and are known to have a global impact, potentially even on the upcoming northern Winter season.

"The Southern Hemisphere does not experience these winter stratospheric warming events so often, with only a few known events in the past decades."
