Climate change – research suggests it is not a swindle

Testing the link between cosmic rays and cloud cover

New research has dealt a blow to the skeptics who argue that climate change is all due to cosmic rays rather than to man-made greenhouse gases. The new evidence shows no reliable connection between the cosmic ray intensity and cloud cover.

Lauded and criticised for offering a possible way out of the dangers of man made climate change, UK TV Channel 4's programme "The Great Global Warming Swindle", broadcast in 2007, suggested that global warming is due to a decrease in cosmic rays over the last hundred years.

This would cause a decrease in the production of low clouds allowing more heat from the sun to warm the Earth and cause global warming.

Research published today, Thursday 3 April, in the Institute of Physics' Environmental Research Letters shows how a team from Lancaster and Durham Universities sought a means to prove the correlation between the ionizing cosmic rays and the production of low cloud cover.
