Every objects emit thermal radiation. Now consider this case: Sun emits waves in a certian electromagneic spectrum (UV + thermal radiation + ecc...); glass is transparent to thermal radiation that usually reach Earth's surface. UV and other radiations are mainly absorbed by Ozone and other gasses in the atmosphere thus (in a hypotetical scenario) Sun can not transmit energy to glass. SO the piece of glass, which is emitting energy, should be lowering his temperature. It is obviusly not possible, but what did I miss?
