On March 16, our local newspaper (Seattle Times) ran a half page syndicated article by Seth Robinson of the Associated Press on some proposed solutions to global warming. They included seeding seas with iron to induce plankton growth, a man-made volcanoe that would shoot tremendous amounts of sulfur high into the stratosphere, a space sunshade produced by trillions of small reflectors placed between the Earth and the Sun and an artificial forest of tree like machines designed to remove CO2 from the atmosphere.
Not long ago on another thread, I posted a story as how our removal of particulates from emissions over the past fifty years has improved air quality but has contributed to global warming by reducing solar energy reflection. The idea about the man-made volcano gave me another idea. During WWII, our destroyers could produce smoke at will by injecting oil into their exhast systems. It shouldn't be too hard to design a similar system that could operate on aircraft jet engines. Planes flying at high altitude on trans polar flights could turn on their smoke generators. It wouldn't take too many years before they created an Artic haze. This haze would reflect solar energy back into space and tend to cool the Artic region, reduce glacier and sea ice melting and as an added benefit provide some cloud seeding to increase winter snow packs. This idea would probably get a lot of objections from the clean air addicts. There objections might be countered by calling this proposal a "Save the Polar Bear" project.
