The United States consumes 3,749,846 thousand megawatt hours each year. Assuming all of that energy was dumped to the earth's atmosphere instantaneously. How thick (i.e. altitude-wise) would the atmosphere have to be in order to have a temperature rise of no more than 0.5 C? Assume all of the atmosphere is at 15 C and 101.33 kPa. Assume constant specific heats at 300 K & neglect any boundary work.
