The work of Henrik Svensmark is highly controversial and has been debunked by many of the world’s leading climatologists. His only solid support for his theory is fellow scientist Eigil Friis-Christensen.

It is significant that his work was not recognised by the United Nations appointed Intergovern- mental Panel on Climate Change. This panel of 50 of the world’s top scientific brains was tasked with reviewing every single scrap of evidence on global warming, both positive and negative, over the past five years. Their conclusion was emphatic.

It said: “Atmospheric concentrations of CO2 in 2005 exceed by far the natural range over the last 650,000 years. The global increases in carbon dioxide concentration are due primarily to fossil fuel use and land-use change, while those of methane and nitrous oxide are primarily due to agriculture.” Hard, supported and proveable evidence, rather than the unproven theory of Svensmark.

Everybody is entitled to their opinions but let us deal with proven facts rather than half-baked theory.
