Comments P.32 left column top paragraph: "The solar electromagnetic energy reaching the Earth’s surface (160 W×m^–2, see Light energy and the spectral distribution of radiation) surpasses the energy contributed by all other sources by four to five orders of magnitude (electric discharge, radioactivity, volcanism, or meteoritic impacts, ~0.0062 W×m^–2 on primordial Earth, primary source, present day geothermal energy ~0.0292 W×m^-2, K. Nealson, personal communication)." Note: BNID 103709 gives value of 1366 W/m^2 for solar electromagnetic energy
