Runaway greenhouse effect a load of nonsense
So argues Steve Goddard.
The way a greenhouse effect works is by shortwave radiation warming the ground, and greenhouse gases impeding the return of long wave radiation to space. Since there is very little sunshine reaching below 30km on Venus, it does not warm the surface much.
And all that cloud cover on Venus reflects 65% of the sunshine back into space. Also, there’s almost no water vapour on Venus. Goddard goes on to argue it’s the intensely high atmospheric pressure that keeps Venus so hot.
Read on for the nitty gritty.
