Like Venus
What would temperatures on Venus be like if it had an earthlike atmosphere?

Assuming an Earthlike atmosphere is possible. Would the polar regions dip below zero, even though Venus is closer to the Sun? Would there be places where the average temperatures are tolerable to humans?
ASSUMING an earth like temperature is possible

If you have a Venus sized planet in a Venus-like orbit, but with an Earth-like rotation and an Earth-like atmosphere, then you would probably end up with scorching deserts at the equator, tropical jungles in the temperate regions, and temperate zones at the poles.
For humans, the best place I would imagine to be the high latitudes, but not the actual polar regions - because personally I don't fancy 6 months of even temperate darkness. Oh wait, Venus-like orbit, so 112 days of darkness... but still.

And if most of the planet was lush and tropical, just think of the insects in the warmer regions.... that thought would send me to the poles!

If you wanted to MAKE an Earth-like atmosphere on Venus, you'd have to find a way to remove most of the existing atmosphere, and induce a faster rotation somehow.... not easy to accomplish!
And you might want to trigger plate tectonics if you can!
