The pressure is the same as being about 2000 feet underwater. High pressure compression increases temperature.
Basically, there is no greenhouse effect on Venus. The calculations have already been made based on its distance from the sun, it's got 95% CO2 and the expected temperature is only about 2 degrees off.
