The 2015 Paris climate agreement is a highly costly treaty that will change little. That's the view of Bjorn Lomborg, who's been named one of the most influential people of the 21st century. Lomborg, who has his own think tank and has written several books on the issue, admits that climate change is real, but says the Paris accord is a tiny way of doing something about global warming. He argues that it will solve just one percent of the problem at a very high cost.
Lomborg argues that what we should be doing instead is investing the money into research and development of green energy, which needs to be made cheaper than fossil fuels. He joined us for Perspective.
