Also you provide a good point about self-interest creating bias in judging the evidence.

The present time may be a couple degrees cooler than 10,000 years ago at that remote location, but I don’t think that would be true for the global average temperature. Also, the time scale is so squeezed that you can’t tell whether the warmings of the past occurred over 1000 years or over 100 years.

So his Graph 13 is no more “truthful” than the previous graphs.

I think the graph here http://en.wikipedia.org/wiki/Global_warming#Historical_warming_of_the_Earth is better. It shows the last 2000 years, and is not as reassuring as his Graph 13.

Whether we can prove that the recent global warming is due to man or not, there is nevertheless a good possibility of that, which has not been disproved. On the other hand, the chance of Apophis hitting us is estimated at 1 in 43000! And even if it does, I doubt it would do as much disruption as the kind of global warming we may be getting into. It would be comparable to a few Krakatoas in energy.

Could one find a statistically significant correlation between people’s beliefs about global warming and their use of fossil fuels?
