A great interview with a great physicist, Freeman Dyson, a good read and an astounding calculation

A great interview.

This interview was shown done by The Vancouver Sun. It's well worth watching.

Freeman Dyson

Click here to see the Interview with Freeman Dyson.

Professor Freeman discusses climate models in some detail, and points out the rarely acknowledged benefits of increased CO2.

A good read

I've been reading a book by Alex Epstein called The Moral Case for Fossil Fuels. In the book Mr. Epstein points out how much we've benefited from their use.

Here's a review by a greeny who at first claimed he "wouldn’t read it, never mind review it." He then goes on to compare fossil fuel use to slavery. If you have a strong stomach and stronger streak of gullibility, you can read the review by clicking: Review of Alex Epstein's book

Later on I'll do my own review.

An astounding calculation

The IPCC says that doubling CO2 will raise the temperature of the atmosphere by between1.5 and 4.5 degrees Celsius.  I was astounded to learn where this number came from.

In the 1970s, a  Japanese physicist,Syukuro Manabe, developed an one of the first climate models. It predicted an increase of 2 degrees Celsius for a doubling of CO2.  James Hansen, formally of NASA, had a different model that predicted an increase of 4 degrees Celsius. Both models were assumed to have an error of 0.5 degrees Celsius.

In 1979 a committee of the US National Academy of Sciences decided to subtract 0.5 from the lower estimate and add 0.5 to the bigger estimate giving the range of 1.5 to 4.5 degrees that remains nearly unchanged today.

This incredibly unscientific piece of nonsense could only have come from a committee. It's more that a little worrying that it came form a committee of 'scientists'.

You can read more at: Wikipedia article on climate sensitivity The section that claims this is in the section entitled 'Consensus estimates', as if consensus had anything to do with science.
