Climate models are wrong

The world has not warmed significantly for the 15 years and this proves that carbon dioxide does not cause dangerous global warming

Regarding the interview with David MacKay. Sadly, almost everything he says is based on a demonstrably false assumption: that man-made carbon dioxide causes dangerous global warming.

The world has not warmed significantly for the last 10 to 15 years and this proves that carbon dioxide does not cause dangerous global warming. It also proves that the climate models are hopelessly wrong – as are most complex models that do not accurately represent the system being modelled and have inaccurate data for their starting point.

If one looks at the sunspot cycles, the conclusion has to be that the world has entered a cooling cycle. If, for some strange reason, one still wants a low carbon economy then the obvious solution is to move away from coal and shift to gas and nuclear power. This will produce an enormously greater reduction in carbon dioxide and, at the same time, probably reduce the cost of electricity in the long term.

Another option is to refine coal using hydrogen fluoride so that it is clean enough to burn directly in a combined cycle power station. This reduces the cost of coal-fired generation and reduces carbon dioxide. The technology is proven and all that needs to is less than $100 million to build a pilot plant–a fraction of the money that has been squandered on wind, solar and marine power.

What the world desperately needs is a return to reason, common sense and analysis based on actual data rather than believing unproven computer models that, so far have totally failed in their predictions.
