This is one of the three extra films to A Breath of Venus (see Links below). Planetary Scientist Colin Wilson (Univ. of Oxford) explains how one can roughly calculate the equilibrium temperature of a planet, how that compares to the measured temperature at the surface and how it relates to the greenhouse effect. But what does he do in that tree?

Production: Produced by Lightcurve Films with the support of the ESA/Venus Express mission (2007).
