Sulpher dioxide , combating global cooling by Hezikia

There is a new way to combat global warming by artificially creating global cooling.How you might wonder? It is easy by simply pumping tons of sulphur dioxide into the atmosphere. The sulphur dioxide, once injected into the stratosphere, will combine with other chemicals to form a substance that reflects sunlight. The sulphur would come from mines in Canada. To really combat global warming in this manner, most effectively, two launching sights would be needed; one at each of the two poles. The really great part about it is that the substance is actually already in the atmosphere due to the fact that factories produce it as well. The current estimated cost is actually lower than Al Gore raising awareness for global warming.
