The earth is circa 6 billion years old, we have accurate records of a couple of hundred years or so.

So we have accurate records for 0.000000033% of the lifetime of the planet and are trying to extrapolate the future from that. Good luck, I think there may a margin of error.

I'm not a climate change objector. The climate is changing, it is evident. Are humans influencing that change? Yes of course we are. How much are we influencing it? Well now that is the question.

The earth has been warming and sea levels rising for millennia. The are ruins of great ancient cities underwater around the globe, discovered below the waves way before man started pumping out large volumes of CO2.

Should we actively try to reduce our CO2? Of course we should, but neither should we disable our ability to compete globally by saddling ourselves with expensive electricity produced solely from "green" sources.
