One solution proposed is simulating volcano by adding sulfur to the atmosphere. In an actual volcano in 1991 in Mount Pinatubo in the Philippines cooled the earth by 0.9 degrees. However, Simone Tilmes of the National Center for Atmospheric Research argued that this would only create temperature difference in small areas and may even destroy atmospheric ozone. Another proposed solution, fertilizing oceans, is believed, by Charles Miller of Oregon State University, to actually create dead spots in the ocean. It also will not move at a rate even close enough to combat raising carbon emissions. Geo-engineering is predicted to continue to destroy the ozone layer, according to Susan Soloman from the Journal of Geophysical Research. Using aerosol products to reflect incoming solar radiation will continue this pattern. Reflecting sunlight, one proposal to reduce the global temperature in response to climate change would be greatly detrimental to solar energy production. Solar energy is a green energy that creates no green house gas.
