Experts reject Bjørn Lomborg's view on 2C warming target

Experts have challenged a claim by Bjørn Lomborg’s Copenhagen Consensus Centre that holding global temperature rises to 2C is a poor investment.

Academics say Bjørn Lomborg’s Copenhagen Consensus
Centre’s assessment on global warming is superseded by
renewable energy advances and Paris climate agreement.

In 2015 the education department abandoned plans for Lomborg to set up an Australian Consensus Centre, but gave the Copenhagen centre $640,000 to support its Smarter UN Post-2015 Development Goals project.

The project assessed dozens of development goals and found investment in keeping global temperature rises below 2C would return less than $1 for every $1 spent, which it rated “poor” compared with other possible investments.

The claim was based on a 2014 assessment paper by Isabel Galiana. The finding on the 2C limit was one of the project’s most controversial, and has been cited in the political debate about whether such targets are worthwhile, as concerns are raised that president Donald Trump will lead the United States out of the Paris agreement.
