Comments: DOE Climate Science Study

Ed. Note: These comments were prepared in support of the U.S. Department of Energy study, “A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate.” For legal reasons, the DOE has disbanded the effort, inviting the authors to respond to criticisms on their own time. The comments below are for the record.

The new DOE report, A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate (July 29, 2025) is a welcome rebuttal to “the cause” (a Climategate term) of climate alarm and policy activism. Its optimistic view of CO₂ enrichment and climate change should be welcomed by all interested in the subject.

This comment highlights quotations from climate scientists who are not associated with the “skeptic” or “realist” school of climate science (such as the 2025 Climate Working Group), but who nonetheless rightly understand energy as the master resource and the uncertainties of climate modeling.…

Solar Books to Skip

With the bust of the rooftop solar industry in the U.S. (“Solar Bankruptcies: The New Normal“), a quick look at some of the trendy books from the political boom is illustrative. Grid solar is hanging on thanks to government intervention, but a bust is developing there.

Lisa Sachs (Columbia University): Assume, Don’t Debate, Premises

“The least Columbia University can do is to invite leading scholars on the non-alarmist side to present the case for CO2/climate optimism. For the students … for civil debate … for good public policy.”

I like Lisa Sachs although I have never met her. The director of the Columbia Center for Sustainable Investing allows my challenging comments rather than cancel me like many other climate academics on the Progressive Left. And I can score some points to let the alarmists/activists know that they are short-changing the learning process if not reality itself.

This is a new era of debate about all things climate and energy. Columbia University might well be one of the last bastions of alarmism/activism, like the New York Times. But here comes the loyal opposition ….

I have debated Lisa Sachs before.…
