> [^1] in fact, if you put it in the shade then it would warm up because it could no longer radiate to space. If I understand correctly, this isn't quite right. If it's in the shade, then whatever is shading it is radiating more heat onto it (because the shading object is hotter than space) and possibly reflecting its own radiated heat back. If it's under a clear sky then it's receiving less heat, so what it loses by radiating has more effect. Does that sound right?
