Bjørn Lomborg

Bjørn Lomborg (born 6 January 1965) is a Danish author, academic, and environmental writer. He is an adjunct professor at the Copenhagen Business School, director of the Copenhagen Consensus Centre and a former director of the Environmental Assessment Institute in Copenhagen. He became internationally known for his best-selling and controversial book The Skeptical Environmentalist (2001).

In 2002, Lomborg and the Environmental Assessment Institute founded the Copenhagen Consensus, which seeks to establish priorities for advancing global welfare using methodologies based on the theory of welfare economics.

Lomborg campaigned against the Kyoto Protocol and other measures to cut carbon emissions in the short-term, and argued for adaptation to short-term temperature rises as they are inevitable, and for spending money on research and development for longer-term environmental solutions, and on other important world problems such as AIDS, malaria and malnutrition. In his critique of the 2012 United Nations Conference on Environment and Development, Lomborg stated: "Global warming is by no means our main environmental threat."

Lomborg initially called the greenhouse effect "a myth" and "extremely doubtful". In the chapter on climate change in his 2001 book A Skeptical Environmentalist he states; "This chapter accepts the reality of man-made global warming but questions the way in which future scenarios have been arrived at and finds that forecasts of climate change of 6 degrees by the end of the century are not plausible." Lomborg claims to have consistently supported the position that global warming exists, but cost benefit analyses, as calculated by the Copenhagen Consensus ranked climate mitigation initiatives low on a list of international development initiatives when first done in 2004. In a 2010 interview with the New Statesman, Lomborg summarized his position on climate change: "Global warming is real – it is man-made and it is an important problem. But it is not the end of the world."
