THE first clear link between ginger hair and climate change has been established by scientists at Dundee University.
Project leader Dr Henry Brubaker said: "We looked at photographs of a huge variety of people and asked ourselves, 'which of these is most likely to be the cause of climate change?' and every time we chose a ginger. Every single time."
The UK government is to launch a £20 million campaign to encourage ginger owners to switch them off at the wall rather than leave them on stand-by.
Dr Brubaker said the science linking climate change to gingers was complex but added: "It's mainly to do with the colour of their hair."
President Bush will use the results of the US government-funded study to lobby for a watered down climate change agreement at the G8 in Germany.
A White House spokesman said: "Climate change is not caused by fossil fuels: fact. The challenge now is, how do we deal with the gingers?"
European governments are pushing for higher taxes to reduce the overall size of gingers while the US favours investment in ginger-capture technology.
