President Biden addressed the United Nations General Assembly on Tuesday, highlighting the need for countries around the world to continue initiatives to stave off the impact of climate change.

Copenhagen Consensus President Bjorn Lomborg joins Martha as he explains the hidden costs of these global climate efforts, how forcing citizens into green initiatives does not change the effects of climate change, and discusses the innovations that could be made in the field of renewable energy.

Then, Bjorn lays out the ideas in his new book Best Things First, where with the help of the world's lead economists and thinkers, he lays out the 12 initiatives that can increase global wealth and quality of life.
