   The very thick greenhouse gas atmosphere means that surface temperature   
   will be spread quite evenly throughout the planet. That same phenomenon   
   explains why global warming here on Earth is increasing temperatures in   
   polar regions much faster than in equatorial regions, the temperatures   
   are equalizing a little bit. So you will not find a region of Venus with   
   temperatures of 305 °C.
