Same physics. Your oven beams infrared radiation at food which absorbs the radiation to heat it up.

The earth radiates infrared radiation that the CO2 in the atmosphere absorbs to heat it up.

It is the Theory of Infrared Spectroscopy. It's a law of physics. The earth MUST heat up this way. If he thinks it isn't happening, the burden is on him to say what mechanism is cooling the earth exactly tp counteract the heating that MUST occur.

If it doesn't work, then your friend has been eating cold leftovers for the last 40 years.
