- The Earth has an average surface temperature of 288K and the Sun has an average surface temperature of 5800K. Assume them to be black bodies. If the only radiation that either black body emitted was at it's peak wavelength how many more photons would Earth need to radiation than receive in order for the climate to be stable.One of the first signs of sunburn is the reddening of the skin (called erythema). As a very rough rule of thumb, erythema occurs if 14.0 mJ of ultraviolet light of approximately 308 nm wavelength (referred to as UVB radiation) is incident on the skin per square centimeter during a single exposure.
