A large, rapid "warming rebound" could result if the technology fails or is stopped, especially if there are no parallel efforts to reduce greenhouse gas emissions. (For more on geo-engineering, see this earlier post.) [...] [...] Using geo-engineering to reduce the amount of sunlight reaching the Earth's surface is extremely dangerous.

This gas is converted to sulfate aerosols, which reflect sunlight and have a cooling effect. Because of the way the atmosphere circulates, tropical volcanoes have a stronger cooling effect than mid- and high-latitude eruptions of the same magnitude.

Didn't the chemists gave us nitrogen based pesticides, which is polluting our river? Haven't we spend billions of dollars on cancer and we still haven't found a cure, and we will probably won't because we are looking after the facts instead of preventing it. If the three main contributors for CO2 are the production of electricity by burning coal, transportation by refining gasoline from oil and the making of cement for construction, Why not eliminated them or make the transition to alternative energies?
