THE GREAT CLIMATE CHANGE RETREAT

A key scientist has conceded that there has been no "statistically significant" rise since 1995

THERE has been no global warming for 15 years, a key scientist admitted yesterday in a major U-turn.

Professor Phil Jones, who is at the centre of the "Climategate" affair, conceded that there has been no "statistically significant" rise in temperatures since 1995.

The admission comes as new research casts serious doubt on temperature records collected around the world and used to support the global warming theory.

Researchers said yesterday that warming recorded by weather stations was often caused by local factors rather than global change.

The revelations will be seized upon by sceptics as fresh evidence that the science of global warming is flawed and climate change is not man-made.

The Daily Express has led the way in exposing flaws in the arguments supporting global warming.

Last month we revealed how the UN's International Panel on Climate Change was forced to admit its key claim that Himalayan glaciers would melt by 2035 was "speculation" lifted from a 1999 magazine article. The influential IPCC then admitted it had got the key claim wrong and announced a review.

The Daily Express has also published a dossier listing 100 reasons why global warming was part of a natural cycle and not man-made.

Yesterday it emerged that Professor Jones, whose raw data is crucial to the theory of climate change, had admitted he has trouble "keeping track" of the information.

Colleagues have expressed concern that the reason he has refused Freedom of Information requests for the data is that he has lost some of the crucial papers.

Professor Jones also conceded for the first time that the world may have been warmer in medieval times than now. Sceptics have long argued the world was warmer between 800 and 1300AD because of high temperatures in northern countries.

Climate change advocates have always said these temperatures cannot be compared to present day global warming figures because they only apply to one specific zone.

But Professor Jones said: "There is much debate over whether the Medieval Warm Period was global in extent or not.

The MWP is most clearly expressed in parts of North America, the North Atlantic and Europe and parts of Asia.

"For it to be global in extent, the MWP would need to be seen clearly in more records from the tropical regions and the southern hemisphere. There are very few climatic records for these latter two regions.

"Of course, if the MWP was shown to be global in extent and as warm or warmer than today, then obviously the late 20th century warmth would not be unprecedented."

Professor Jones first came under scrutiny when he stepped down as director of the University of East Anglia's Climatic Research Unit in which leaked emails were said to show scientists were manipulating data.

Researchers were accused of deliberately removing a "blip" in findings between 1920 and 1940, which showed an increase in the Earth's temperature.

John Christy, professor of atmospheric science at the University of Alabama and a former lead author on the IPCC, said: "The apparent temperature rise was actually caused by local factors affecting the weather stations, such as land development."

Ross McKitrick, of the University of Guelph, Canada, who was invited to review the IPCC's last report said: "We concluded, with overwhelming statistical significance, that the IPCC's climate data are contaminated with surface effects from industrialisation and data quality problems. These add up to a large warming bias."
