If you've been following this thread -- you will recall that a few posts back W*gs denied vociferously that he ever claimed that Vulcanism over nearly all of the Venusian planet was caused by a runaway greenhouse effect.
Now he states (above) that it is. Obviously he doesn't have a clue what he's talking about.
For the record -- there is no chance that a greenhouse phenomenon can heat up the core of a planet -- and cause vulcanism like what exists on Venus. No chance.
At least 60% of the sunlight reaching Venus is reflected away by the dense cloud cover -- so only 40% of the sunlight is available for the greenhouse effect.
