You probably didn't read the recent United Nations IPCC 4,000 page report on global warming impacts. But you definitely saw the media headlines about it screaming, "A Code Red for Humanity!" But the report did not predict any catastrophic, extinction level events, and if you ask Dr. Bjorn Lomborg, it was actually quite reasonable. Bjorn returns to break down what the report actually says, the truth about heat wave and hurricane trends, and give reasons why we can all be optimistic about Earth's future.

Dr. Bjorn Lomborg is president of the Copenhagen Consensus Center, and visiting fellow at the Hoover Institution, Stanford University. The Copenhagen Consensus Center is a think-tank that researches the smartest ways to do good. For this work, Lomborg was named one of TIME magazine's 100 most influential people in the world. His numerous books include "False Alarm: How Climate Change Panic Costs Us Trillions, Hurts the Poor, and Fails to Fix the Planet", "The Skeptical Environmentalist", "Cool It", "How to Spend $75 Billion to Make the World a Better Place", "The Nobel Laureates' Guide to the Smartest Targets for the World 2016-2030" and "Prioritizing Development: A Cost Benefit Analysis of the UN's SDGs".
