There still seems to be something missing in the article on the "heat" topic, it states that "IR light from the sun only accounts for 50% of the heating of the Earth, the rest is caused by visible light."  Doesn't some of the heat on the earth come from other forms of electromagnetic radiation from the sun other than visible light?   Or is the absorbtion rate for other non-visible electromagnetic waves that the sun produce just too low to count?   This should be clarified, since the article also stated that "Light or electromagnetic waves of any frequency will heat surfaces which absorb it."
