Re: Is it possible to have a rational debate on global warmi

Guys, the greybody model assumes the Earth emits like a sphere, and receives like a disk . A disk. The surface area receiving radiation is taken to be one fourth of the surface area emitting. As per the equations A=piR 2 for the area of a circle and A=4piR 2 for the surface area of a sphere. A bit ...

As I said above, if you average the insolation across a hemisphere it could produce a temperature up to 303 K, from there the only way to get a 255 K average is if the temperature drops 100 K overnight. With an atmosphere taking over from purely radiative forms of heat loss you would be hard presse...
