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?
