Propaganda, disinformation, nonsense and bare-faced lies continue to pour out of the mouths of the global warming fanatics. They are not even qualified to issue their propaganda.

For example, the Intergovernmental Panel on Climate Change (IPCC) likes to advertise itself as the representative body of world experts on the subject. It is not so, being largely made up of politicians with, perhaps, as few as 25 climatologists in its ranks.

By contrast, there are many highly qualified and experienced climatologists who get together from time to time and issue reports - reports which argue convincingly against the IPCC, but which generally go unmentioned in the media where the entire global warming fraud has been swallowed whole.

Other distinguished scientists (Professor Syun-Ichi Akasofu, former Director of the Arctic Research Centre, and Dr Willie Soon, of the Harvard-Smithsonian Centre for Astrophysics) have made telling criticisms of the scare stories. Among them was the fact that sea levels are not rising catastrophically, but merely continuing the modest annual increase of 3mm over the past 200 years; the Antarctic ice-sheet is not melting, except in one small corner of that great frozen expanse; and tropical hurricane activity has not, as predicted by the global warmers, increased, but is at its lowest level for 30 years.

Perhaps the world's most knowledgeable person in the world on the subject of the monitoring sea levels is Nils-Axel Morner, formerly chairman of the International Commission on Sea-level Change, who dismisses recent reports of catastrophically rising sea levels as hysteria. He writes: "The sea is not rising. It has not risen for fifty years. If there is any rise in the 21st Century, it will not be by more than four inches."

Six times he and his team visited the Maldives and confirmed the sea has not risen there for 50 years. The government of the Maldives, which has been campaigning for years for vast sums of money to avert disaster, refused to publish Dr Morner's findings.

In Tuvalu, where local politicians have been calling for the funded evacuation of the locality for 20 years, the sea level has fallen in the most recent decades.

The IPCC has warned that sea levels are rising by 2.3mm every year, but Dr Morner found that its experts had drawn on the findings of a single tide-gauge in Hong Kong harbour.

The entire global sea level projection was then adjusted upwards by a "corrective factor" of 2.3mm because, as the IPCC scientists admitted, "we needed to show a trend."

Dr Morner also discovered that not one of the IPCC's contributing expert authors on sea levels is a sea level specialist. In fact, the reliance on rigged computer models forms the basis of the whole of the warmists' propaganda.

The latest results of this and other surveys of the Arctic show that, in fact, since March 2008 the ice has thickened by at least half a metre. And ice thickness in the Antarctic is well above its 30-year average.

It is worth repeating that global temperatures have been on a downward trend since 2002 "by a rate that averages out at 0.25 a degree per decade". Yet this consistent fall is happening while the actual amount of CO2 gas is going up. This is the very opposite of what all the warmists' computer models say we should expect. But, as usual with the global warming fanatics, mere facts are never enough to spoil a good scare story.
