The Last Gasp of the Climate Thought Police
Following my lecture last week at Cornell, one Cornell professor, a well-known climate activist, called for the firing of the director of the Cornell Atkinson Institute for Sustainability — an accomplished scientist himself — simply for hosting my visit. Gavin Schimdt, a NASA scientist and another well-known climate activist, took to social media to complain that I had cited…

Science Evolved. The Narrative Didn’t.
I spent this week in Ithaca, New York visiting Cornell University. It was a fantastic visit. I met with faculty, researchers, students, staff, administrators, and taught a few classes. I was warmly welcomed and had a chance to discuss, debate, listen, learn, agree, disagree, and break bread with many colleagues. In short, my visit revealed…

When Less Warming Means More Fear
Something curious is going on in the world of climate advocacy. As THB readers know, projected future carbon-dioxide emissions from fossil-fuel combustion have been consistently revised downward in recent years, resulting in less projected warming. Yet rather than acknowledge this encouraging development, climate campaigners have shifted the goalposts by lowering the threshold of what they…

Comment Submitted to the Department of the Interior, Bureau of Land Management
Summary: BLM proposes “to rescind” the 2024 final “Conservation and Landscape Health Rule” adopted on May 9, 2024. Despite the promise in the 2024 final rule that it “defines the term ‘ecosystem resilience,’” no such definition actually is presented in the 2024 final rule. Instead, there are numerous references to such concepts as ecosystem health,…

The Global Population Crisis that Never Was
Thomas Malthus was a fan of pandemics. Writing in 1798 in his famous treatise on population growth, Malthus encouraged the spread of fatal diseases: “Instead of recommending cleanliness to the poor, we should encourage contrary habits.” He criticized “benevolent, but much mistaken men” who were seeking to eliminate fatal diseases, rather than see them as a way…

More Problems with Australia’s National Climate Risk Assessment
When Australia’s National Climate Risk Assessment (NCRA) was released last week, headlines such as the above announced that “climate change could cost Australians $40 billion per year by 2050.” It turns out that claim is demonstrably false. Let’s take a close look. The NCRA asserts the $40 billion cost on p. 102: The Colvin Review (2024) projected disaster costs…

Extreme Non-Event Attribution
Last week, Hurricane Erin was a massive Category 5 storm that shot the gap between the U.S. east coast and Bermuda before heading out to sea. Imagine an alternative universe, where Erin’s track was just a bit further west — tracking over Miami, along the U.S. east coast, and then making a direct hit on…

UN abandons science and hires climate change zealots who damn the facts
Life would be impossible without experts — doctors help us when we get sick, mechanics fix our cars when they break down, farmers produce our food, to name just a few. But we live in a time when too many of these roles have become politicized. President Trump recently fired the head of the Bureau of…

A Takeover of the IPCC
The Intergovernmental Panel on Climate Change (IPCC) has just released the names of its authors for its seventh assessment report (AR7). The author list for its Chapter 3 — Changes in regional climate and extremes, and their causes — suggests strongly that the IPCC will be shifting from its longstanding focus on detection and attribution (D&A) of extreme events…
