The U.S. Supreme Court is set to hear one of the most consequential climate-related cases in the country this October: Suncor Energy v. County Commissioners of Boulder County. At issue is whether cities and counties can sue oil and gas companies for alleged damages caused by climate change, or whether federal law prevents state courts from hearing these claims.

Boulder County and the City of Boulder are seeking damages they say are ...

Millions of Americans believe that everything from groceries and cars to homes and vacations has become impossibly expensive. But are things actually less affordable than they were in the past, or are we measuring affordability the wrong way?

In this episode of Sanity Check, Cal Beisner revisits a question raised during his recent appearance on David Wheaton’s The Christian Worldview: Why are so many Americans, particularly yo...

In this episode, Dr. David Legates examines the growing legal battle over “citizen suits” and who has the authority to enforce federal environmental law. The Clean Air Act, Clean Water Act, and Safe Drinking Water Act all gave private citizens and organizations the ability to sue when they believed environmental laws were being violated. For decades, these provisions have allowed environmental groups to challenge compan...

Europe has been warming significantly faster than the global average, and this summer’s heatwaves once again prompted politicians and environmental activists to point to fossil-fuel emissions as the obvious culprit. In this episode, Dr. David Legates examines a new study that suggests there is another important piece of the story: Europe’s remarkable success in reducing air pollution.

Since 1980, Europe has drama...

When CNN declared that the July heat wave would have been "virtually impossible" without fossil fuel emissions, it pointed to a rapid-attribution study as proof. But does the evidence support such a sweeping claim?

In this episode of Sanity Check, Dr. David Legates examines the meteorology behind the heat wave, explains how attribution studies are conducted, and explores the assumptions driving claims that individual weather events ...

Secretary of State Marco Rubio’s recent visit to India highlighted a growing area of agreement between two of the world’s largest democracies: the need for abundant, reliable energy. As India’s economy expands and hundreds of millions continue moving into the middle class, demand for electricity, transportation fuels, and industrial energy is set to rise dramatically in the decades ahead.

In this episode, Vijay Jay...

In this episode of Sanity Check, David Legates examines a Guardian article claiming that U.S. immigration enforcement flights carry a "huge climate cost." Looking beyond the headline, he compares the reported emissions with total U.S. greenhouse gas emissions, aviation emissions, and other major sources to ask whether the article's conclusions are supported by meaningful context. Along the way, he discusses media framing, statistic...

After a string of high-profile climate lawsuits, the Ninth Circuit Court of Appeals has delivered a ruling that supporters of sound energy policy may have reason to celebrate.

In this episode of Sanity Check, David Legates examines a lawsuit brought by twenty-three young activists challenging President Trump's executive orders aimed at expanding domestic energy production. The plaintiffs argued that policies supporting oil, gas, hyd...

El Niño may begin as a patch of unusually warm water in the Pacific Ocean, but its effects can be felt across the globe. In this episode of Sanity Check, David R. Legates explores one of the most powerful climate phenomena on Earth and explains why forecasters are closely watching the possibility of a particularly strong El Niño developing in the months ahead.

This episode of Sanity Check examines a question that sits at the heart of modern scientific culture: Can science remain ethical when divorced from a moral framework? Drawing from a standout presentation delivered at the recent Cornwall Alliance Spring Conference in Memphis, Daniel O’Malley argues that science can tell us what can be done, but not what should be done—and that without Christianity, science risks becoming...

For years, the most extreme climate scenarios shaped headlines, policy debates, and public fear—despite growing evidence that many of those projections were increasingly detached from real-world energy and emissions trends. Now, in a major shift ahead of the IPCC’s Seventh Assessment Report, climate modelers are quietly abandoning some of their most dramatic assumptions. 

In this episode of Sanity Check, David R. Le...
