it appears that you're right i put too much faith any at all into the poster who put up that text in the first place we should estimate the temperature shift required to produce our energy the electricity economy is by those old estimates e the temperature of the solar radiation is the area of earth is the cross sectional area that earth presents to the sun is hence the self consistent estimate of the earth's effective temperature is ignoring electricity subbing the electricity demand in net difference there is clearly more than enough thermal radiation to satisfy our needs we should remove that section
