Global Warming~?
Global Warming is a topic that can be all pointed to ones opinion.
Over thirty years ago there were scientists saying it was global cooling and now they are saying that it is global warming.
One thought is that Global warming is real but not to the thoughts of what people think. Global warming is the heating of the earth but not that it’s due to man-made problems but it’s due to the Earth’s cycle. The Earth heats up and cools over time as it always has and always will.
And then theres the other though:
Global Warming is because of pollution people put off. It’s man-made and can be helped if we act now.
…………..
What’s you’re opinion?

Suppose aliens have studied the effects of CO2 on climate for millions of years and performed double blind tests on thousands of planets were to visit us. Suppose they said that climate sensitivity to CO2 was 3.45C per CO2 doubling. On the other hand, what if they said that climate sensitivity to CO2 was 3.44C per CO2 doubling. What difference, in terms of what should be done about AGW would these two numbers make?

That is an excellent description of climate deniers.

As MTRstude pointed out, the heating effect of CO2 is logartihmic. However, an ice free world (as Earth was for most of the last half billion years) would lack melting or accumulating ice as a positive feedback and would have a lower climate sensitivity than Earth. Therefore, in answer to your question, planets which could be considered comparable to Earth would be planets in an ice age, preferably ones in an interglacial.
BGS
You are close. My point is that uncertainty in the exact figure for CO2 doubling should have little effect on policy
