Climate change not man-made

Sir, – Alex Bell’s article on climate change in last week’s Courier (“It’s not a climate for denial”, October 11) continued to preach the wholly unproven theory of man-made climate change.

The IPCC computer models which kickstarted the theory have long been shown to have been total nonsense.

The IPCC has subsequently espoused the “Hockey Stick” theory, which basically stated that the world’s climate had never changed until now.

They persuaded public organisations, such as the BBC, to endorse the theory.

The BBC apparently had a policy of not allowing any critics of the “Hockey Stick” to be heard, and actually publicly apologised and withdrew the programme from the iPlayer when one critic slipped through.

The “Hockey Stick” theory collapsed in the face of geological records which showed that the climate had changed.

The IPCC then quietly dropped all reference to it, though neither they nor the BBC thought fit to apologise.

Climate has always changed: the current cycle shows a warm period approximately every 1,000 years.

In the last warm (Medieval) period temperatures were considerably warmer than they are now. As with the previous (Roman) warm period it was followed by a Little Ice Age.

This resulted in farmlands in Viking Greenland reverting to arctic tundra.

There were annual ice fairs on the River Thames, and all major British rivers regularly froze solid.

In Scotland the growing season was shortened by two months, leading to widespread starvation in the Highlands and Islands.

When the next Little Ice Age comes along, as it must, the problems of our great-grandchildren will be immense.

When I was born there were fewer than two billion people on the planet: now it is 7.5 billion and rising.

The curtailment of the growing season will cause mass starvation.

Britain can produce only 17% of its food requirements from its own resources: the rest comes from the surplus of other nations.

That surplus will disappear.

Man did not cause climate change nor can he do anything to prevent it. It is time to plan for the real future.
