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".

Two big trends have radically transformed space exploration over the past decade: the privatization of the space industry thanks to Elon Musk and the rise of the Chinese space program. What does this mean for NASA’s mission in the 21st century? Are we on the verge of geopolitical battles with China over Moon territories? Why does Elon maybe want to nuke Mars? Space journalist and author Eric Berger joins us to look at what we can expect as humanity enters the next great era of space travel.

Eric Berger is the author of "Liftoff: Elon Musk and the Desperate Early Days That Launched SpaceX." He is the senior space editor at Ars Technica, covering SpaceX, NASA, and everything beyond. Follow him on Twitter at @SciGuySpace.

Is there an infrastructure crisis in America? Would we really need $1.5 trillion in new spending to solve it? Dr. Ed Glaeser joins us to break down the good, the bad, and the ugly of the new infrastructure bill, and help debunk the magical thinking among Democrats that if we just spend massive amounts of money on rail lines, we'll revitalize stagnant economies.

Taking orders from terrorists, silencing political opponents, and implementing unconstitutional COVID mandates ad infinitum.

"nO mORe EnDleSs wArs!" When your entire foreign policy is built upon an emotional slogan, this is what you end up with: a new terrorist safe haven and millions of women and children now under the rule of the Taliban. Dan and Rep. Mike Waltz react to the news that Afghanistan has fallen.

Conservatives are losing the debate over capitalism and free markets, and not just among young college students - a growing number of Americans on the right want more government intervention and stimulus checks. How can we change their minds? Dr. Samuel Gregg thinks it would help if conservatives reframe the economic argument for capitalism as a moral argument - and he joins us to show just how we can do that.
