I’ll try to find it but I only remember the outlines—a few years ago there was a synthesis of a number of satellite datasets which convinced many of the remaining (honest) sceptics.

The only point is that more greenhouse gases, means more greenhouse effect of infrared radiation coming back down from the atmosphere.
