“Scientists, engineers, and policymakers must reject symbolic solutions and focus on measurable, scalable, and scientifically robust strategies. Not all gases are equally dangerous, and not all solutions are equally wise.”

S.L. Cressey’s No Son, There Won’t Be a Hydrogen Economy is a sharp, data-driven critique of the growing hype surrounding hydrogen as a future energy source. The central argument of the book is clear and unwavering: while hydrogen may have limited industrial and aerospace applications, the broader vision of a global “hydrogen economy” is fundamentally flawed—technically, economically, and especially environmentally.

The hydrogen movement, in short, can be likened to “cargo cult science”—a term popularized by physicist Richard Feynman to describe efforts that mimic the appearance of scientific rigor without engaging with its foundational principles.

The book dispels the prospects of hydrogen as a miracle climate solution.…

“Tomlinson is angry and sarcastic. His worldview is losing intellectually, politically, and business-wise. Is it time for him to retire and happily live off his spouse’s (ill-gotten) renewable energy riches?”

The “existential crisis” climate narrative is in meltdown. Houston solar leader John Berger has resigned, his 12-year-old company (Sunnova) positioned for bankruptcy. Other solar and wind stocks are tanking, and offshore wind is out of play. Battery and EV firms are regular restructuring news.

Climate activists find themselves out of taxpayer monies. The U.S. Department of Energy, Department of Interior, and Environmental Protection Agency are implementing President Trump’s “none-of-government” climate policy, reversing Podesta-Biden-Harris climate alarmism and the budget-busting Inflation Reduction Act.

But there is one fossil-fuel-despising business editorialist who is wed to the Climate Industrial Complex, not to mention a multi-millionaire renewables executive (thanks to your tax money).…

“One-sided argumentation/advocacy in place of intellectual rigor is fraudulent and morally wrong. It speaks to desperation in a dark hour. Your climate courses should be restructured or terminated. At a minimum, a new reading curriculum is needed.”

Lisa Sachs, Director of the Columbia Center on Sustainable Investment, and Director of the Columbia Climate School’s Master of Science program in Climate Finance, recently wrote on social media:

Couldn’t be more excited for the official launch of Columbia Climate School‘s new MS in Climate Finance, as I hear from more and more incredible applicants AND practitioners, underscoring the importance, timeliness and breadth of rigorously understanding the intersection of Climate and Finance!!

I responded that climate finance was producing Net Zero for investors, with Sunnova being the most recent example. She deleted the comment and sent me this personal communication:

Rob, I don’t find your comments on my posts very helpful to anyone.

Earlier this year, Our World in Data published a Daily Data on global air pollution. Hannah Ritchie, deputy director and science outreach lead, wrote:

Global emissions of local air pollutants have probably passed their peak. The chart [below] shows estimates of global emissions of pollutants such as sulphur dioxide (which causes acid rain), nitrogen oxides, and black and organic carbon. These pollutants are harmful to human health and can also damage ecosystems.

It looks like emissions have peaked for almost all of these pollutants. Global air pollution is now falling, and we can save many lives by accelerating this decline. The exception is ammonia, which is mainly produced by agriculture. Its emissions are still rising.

Hannah Ritchie notes that some countries are lagging, getting worse.…
