The questions for serious people are: 1. How much, if any significant impact are we having on it 2. What, if anything can we do to mitigate any contribution our activities are making towards it 3. What are the costs to society of doing those things which can, if possible, mitigate our contributions 4. What are the costs to society of adapting to, rather than trying to change climate change 5. Are the costs to simply adapt to the change greater or less than the costs of trying to stop it.
