When you sit in your cold car on a cold day and the sun shining in on you through the window feels warm on your face, that is radiation. It has not warmed up the air in your car, just your face.

Yeah, it's true. Humans seem to like it if the temperature of the objects around them is warm and the air is a little cooler. It creates a more comfortable environment than say if the objects were cooler and the air is warmer. One of my professors explained why once but it escapes me at the moment.
