The Earth has had a mechanism to lose heat for billion of years. We know this because we are going back to 3.3 billion years in seeing the product of life. That means any of us could have walked shirt-sleeve on parts of the planet when it was showing massive meteorite hits and volcanism. All the seas did not boil, and proteins were not baked on land, as the warmies would paint the future.
We owe all this to the marvellous physics properties of water and the atmosphere. With the Earth still cooling, we had to get rid of heat energy at a rate 10 or 1000 times greater than now. This was done through clear-air convection, which brings heat energy up to the near-vacuum stratosphere, and then dumps the heat with infrared radiation, like a standard chocolate double-boiler. Otherwise life would not have survived since the atmosphere had its now-oxygen component taken over by methane and carbon dioxide. We still had our nitrogen component, you can't get rid of that stuff.
Our warmie brothers ignore all this, and like to make up new mechanisms happening right now because of oil companies. If people believe them, then they are right by the definition of groupthink.
