Tom Tamarkin: AGW or climate change is not the big problem many claim. Only fossil hydrocarbon fuels and nuclear energy can supply material amounts of energy due to their many orders of magnitude higher energy flux densities than so called renewables. Once fossil fuels are depleted beyond the point of economically viable production there is only one energy source available to provide the Earth’s energy needs. That is the conversion of matter into energy as formulated in the equation E=mc2.
