"Hail Mary" Technologies to Engineer Earth's Climate

Abstract

Scientists and inventors have proposed a variety of technologies to avoid further increases in the Earth s temperature by greenhouse gases. The two most popular technological approaches are: reflecting solar energy back into space and sequestering and storing carbon to prevent it from reentering the atmosphere. These last ditch efforts are now being referred to as _Hail Mary technologies, or efforts made in desperation with only a small chance of success. However, humankind due to the severity of the situation, has given these _Hail Mary technologies a serious consideration, even though these approaches have not be adequately researched to address one component of a much larger problem.
