It's not gonna be that bad and earth is further back than Venus.
The distance from the sun is not the determining factor here, at all. The determining factor is that Venus' atmosphere is like 99x thicker than ours, and is mostly composed of carbon dioxide, a greenhouse gas. Give Earth that atmosphere, even at our distance, and we'd be like Venus, and there would be no life on this rock.
We're probably looking at dinosaur levels, no ice caps things like that.
We can only hope. But, the potential for runaway greenhouse events is significant.
Dismissing scenarios got us where we are today. Continue to do so at the peril of your descendants.
