A balmy February in Vancouver has meant shipments of snow by the lorry load to deliver some winter to the Olympic Games.
No climate for truth
Anecdotal evidence may add colour to dry statistics. It can humanise the death toll of an earthquake by telling the story of one human trapped inside the ruins or highlight the plight of a soldier locked in combat to illustrate the complexity of a large-scale war. But anecdotes cannot replace hard facts or scientific evidence when crafting policy. As one of the great concerns of our time, nothing is added to the climate debate by throwaway lines about Al Gore's whereabouts during a snowstorm or bobsleigh tracks outside Vancouver that may soon turn to water-slides.
The scientific community and a rigorously produced body of evidence must ultimately have the final say. After this week of snow politics melts away, the world must get back to evaluating the scientific evidence rather than interesting weather tales.
