Comments: >>2) Stratospheric sulphur aerosols look fairly promising, and we can cheaply deploy them with balloons. They might wreck the hydrological cycle in general, and the monsoon in particular. Other aerosols are worth a look.
Balloons are not optimal. Airplanes work fine at Arctic needed altitudes, < 50,000 feet. I don't think anyone really believes "They might wreck the hydrological cycle" -- these are ~5% effects at best, especially doubtful in the Arctic case. >>3) Carbon dioxide air capture looks very promising, but it requires further development, and will take ages to work. Nope. The CROPS method (Metzger & Strand & me) can start right away and works every year to capture at least 10% of world C emissions.
