Most governments in the developed world were elected on platforms that promised aggressive policies on greenhouse gas emissions. The reality has not matched the commitments made. The reasons for this are multitudinous and no one should ever underestimate the difficulties of weaning advanced societies off the use of cheap and convenient access to fossil fuels. But in addition to the standard reasons for slow progress we can see a large number of obstacles that spring from human psychology. In particular, some of the resistance to aggressive action on climate seems to spring from mental attitudes that may have helped us survive as a species in the past. Perhaps politicians intuitively recognise the existence of these barriers. So they continue to say that climate change is the most important problem facing humanity at the same time as adding new runways to the local airport or sanctioning the development of new coal-fired power stations.
The Heartland Institute, a US free-market think tank, held a conference on climate change in New York in early March. It was a forum for some of the climate change sceptics to discuss their research. The conference got very little coverage in the media and was ignored by the science pages of the newspapers.
Bjørn Lomborg, a professor at Copenhagen Business School, is the most formidable critic of those who think that cutting climate-changing gases is the most important problem the world faces. He made his name with ‘The Skeptical Environmentalist’ and his new book continues his drive to get the world to see global warming as just one of the world’s important problems.
