Venus as a comparative example is always going to be unbelievably bad. Venus has no known plate tectonics, although it has a high level of volcanic activity, it is unlikely to have a distinct inner core as it has a very weak or no magnetosphere, atmospheric pressure is 93 times that of Earth, it's rotation is longer than it's orbit and finally it has a CO2 rich atmosphere with a thick layer of sulfur dioxide clouds. Venus is given as an example of the run away green house effect but how the example can ignore the other factors affecting Venus is beyond words.
