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. On…

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…

The Politicization of Intelligence
Last week, Tulsi Gabbard, appointed by President Trump as the Director of National Intelligence, fired the top two officials of the National Intelligence Council (NIC) after The Washington Post and the New York Times reported that the Trump Administration had ignored the findings of its NIC related to its deportation efforts. Today, I explain what is going on, setting the stage…

The Future is Already Here Somewhere
One of the challenges, even for experts, in making sense of climate projections is that the scenarios underlying the projections are so complex as to be impenetrable without a lot of effort and expertise. Opaque assumptions make interpreting climate projections fraught with challenges and consequently, they are easily misinterpreted and misused. Today, I try to…

RIP NOAA’s Billion Dollar Disasters
Last June, my peer-reviewed paper on problems with NOAA’s Billion Dollar Disaster (BDD) tabulation was published. Today, NOAA announced that the BDD tabulation would no longer be updated by the agency, explaining that it has been “retired.” While some media have chosen to make the BDD retirement about the Trump administration, there has also been some excellent reporting indicating…

Ice Surprises
Earlier this week the New York Post asked me to help its readers make sense of some surprising new research on ice dynamics at both poles. The new research appears in a new peer-reviewed paper and a preprint that was just posted. At the South Pole, Wang et al. 2025 find a record accumulation of ice on the Antarctic…

The Underappreciated Importance of Climate Variability
One of the most pervasive misunderstandings of climate — even among some who publish on climate — is the belief that any long-term trend in a measured climate variable indicates a change in climate, as defined by the IPCC. In practice, “long-term” is often defined to be only a few decades worth of observations. Some…

Surprise! Ice is Rebounding at BOTH Poles — Climate is More Complex Than We Know
When it comes to climate change, to invoke one of Al Gore’s favorite sayings, the biggest challenge is not what we don’t know, but what we know for sure but just isn’t so. Two new studies show that the Earth’s climate is far more complex than often acknowledged, reminding us of the importance of pragmatic…

The Iberian Blackout
I’ve spent some time this week looking into the massive blackout that struck Spain and Portugal a few days ago, and today I share some of what I’ve learned. I start with a short primer on grid operations and follow that with some initial thoughts on the significance of the Iberian blackout. The Financial Times explains what…
