In Bellamy's foreword to the 1989 book
The Greenhouse Effect, he wrote: The profligate demands of humankind are causing far-reaching changes to the atmosphere of planet Earth, of this there is no doubt. Earth's temperature is showing an upward swing, the so-called
greenhouse effect, now a subject of international concern. The greenhouse effect may melt the glaciers and ice caps of the world, causing the sea to rise and flood many of our great cities and much of our best farmland. Bellamy's later statements on
global warming indicate that he subsequently changed his views. A letter he published on 16 April 2005 in
New Scientist asserted that a large proportion (555 of 625) of the glaciers being observed by the
World Glacier Monitoring Service were advancing, not retreating.
George Monbiot of
The Guardian tracked down Bellamy's original source for this information and found that it was from
discredited data originally published by Fred Singer, who claimed to have obtained these figures from a 1989 article in the journal
Science; however, Monbiot proved that this article had never existed. Bellamy subsequently accepted that his figures on glaciers were wrong, and announced in a letter to
The Sunday Times in 2005 that he had "decided to draw back from the debate on global warming", although Bellamy jointly authored a paper with Jack Barrett in the refereed
Civil Engineering journal of the
Institution of Civil Engineers, entitled "Climate stability: an inconvenient proof" in May 2007. In 2008 Bellamy signed the
Manhattan Declaration, calling for the immediate halt to any tax-funded attempts to counteract climate change. He maintained a view that man-made climate change is "poppycock", insisting that climate change is part of a natural cycle. His opinions changed the way some organisations viewed Bellamy. The
Royal Society of Wildlife Trusts stated in 2005, "We are not happy with his line on climate change", and Bellamy, who had been president of the Wildlife Trusts since 1995, Bellamy asserted that his views on global warming resulted in the rejection of programme ideas by the BBC. ==Recognition==
