Stratospheric sulfur aerosols are largely considered one geoengineering solutions for global warming. How does this jive with your statement?

Maybe if carefully distributed at optimal locations and altitudes you could maximize the cooling effects while minimizing damage, but random emission from flights in no way optimized for that purpose? No, it's just pollution.
- kortex 5y agoSeconding what jjk said, also airliners cruise in the troposphere, not the stratosphere. > From the planetary surface of the Earth, the average height of the troposphere is 18 km (11 mi; 59,000 ft) in the tropics; 17 km (11 mi; 56,000 ft) in the middle latitudes; and 6 km (3.7 mi; 20,000 ft) in the high latitudes of the polar regions in winter; thus the average height of the troposphere is 13 km (8.1 mi; 43,000 ft). Airliners cruise around flight level 310-380 (31-38,000', about 5.9 to 7.2 miles).
