Estimates of temperature at any given location on Earth based solely on the intensity of solar radiation will be: slightly overestimated at the poles because ice at the poles reflects heat. slightly underestimated at the equator because ocean currents carry heat from the equator toward higher latitudes. very close to actual average annual temperature for that region. slightly overestimated at the equator and underestimated at the poles because heat moves from the equator to the poles.
