LETTER – In 1995 the UN Inter-governmental panel on climate change included a global temperature anomaly chart which agreed with hundreds of scientific papers that dealt with the Medieval Warming Period and the Little Ice Age which followed from 900 to1350AD.

The Earth then was approximately two per cent warmer than now. The Vikings colonised what was a very green Greenland during the warm period. After the Little Ice Age the bodies of the colonists during that period were found under the perma frost.

Some years later the IPPC published a different chart which ignored the wide consensus on the subject and sought to show that a flat temperature had existed throughout the 1,000 years prior to the 20th Century.

This report showed a rapid rise in temperature in the 20th Century which it claimed was the result of human caused global temperature.

This deliberate deception was heavily criticised world-wide by scientific papers which showed that in the Medieval Warm Period temperatures were as much as 3.75 degrees centigrade higher than the present in some places.

Even penguins should know that the UN is not an independent body and that it is driven by those who control by fear. This fear is not because of the increase of fossil fuel but of its limitation as natural sources deplete.

Thus the great majority of us must be taught that we must restrict our use of such (as we are experiencing) while powerful interests control and gain from the restrictions.
