“The Global Fertility Crisis is Worse Than You Think”

The title of today’s post comes from an excellent recent talk in London given by my AEI colleague (and University of Pennsylvania professor), Jesús Fernández-Villaverde.

What is a “Worst Case” Climate Scenario?

The implausibly extreme and hugely popular climate scenario RCP8.5 made it into President Trump’s executive order last week on “Restoring Gold Standard Science.” Ironically, the Trump administration’s characterization of RCP8.5 did not quite reach the “gold standard,” and maybe not even a “bronze standard. “ The EO states: [Federal a]gencies have used Representative Concentration Pathway…

Atlantic Hurricanes Preseason 2025

There has been no tropical cyclone of hurricane strength anywhere in the Northern Hemisphere so far in 2025. If we get to June 5th — which looks quite possible if not probable — then 2025 will have the latest date on record (since 1970) for the first NH hurricane, breaking the record of Ava, which…

Taking Institutional Neutrality Seriously on Campus

In 2024, Academic Freedom Alliance, Heterodox Academy, and the Foundation for Individual Rights and Expression called for colleges and universities to formally adopt institutional neutrality, defined as: “When a contested social issue arises that does not directly concern the academic mission of our college or university, institutional leadership will not issue a position statement on that issue.

Heavy Metal

More than 7,000 years ago, humans first began mining copper. Since then, humans have mined more than 700 million tonnes. According to a fascinating study of the metals requirements of a net zero energy transition, the world will need to produce another 700 million tonnes of copper over the next 22 years. The study, by Simon Michaux of the…
