Climate Doomism Under Predicted?

By Robert Bradley Jr. -- February 11, 2026

“My way of dealing with doom-mongers is to let the person talk for a while and then I ask, gently: “Does feeling this way make you more effective?” – Amory Lovins

Mark Trexler, “Pushing Climate Boulders Uphill Since the 1980s,” posted on social media:

Our biggest climate risk failure hasn’t been inadequate technology or funding. It’s been our reliance for 40 years on predictable models in a chaotic climate system!

Welcome to Deep Ecology, the belief that Nature is optimal and fragile and any human perturbation is bad, even catastrophic. Trexler then lists his examples:

Back in 1987, Wallace Broecker warned in Nature about “unpleasant surprises in the greenhouse” – arguing that Earth’s climate wasn’t a gentle dial, but a roulette wheel capable of sudden, dramatic shifts.
That was almost 40 years ago. He hasn’t been alone in raising this concern, as this curated list of 18 reports from 1987 to 2024 makes clear:

“It’s an impressive and alarming list,” Trexler continues,

𝗯𝘂𝘁 𝘄𝗵𝗮𝘁 𝗰𝗮𝗻 𝘆𝗼𝘂 𝗱𝗼 𝘄𝗶𝘁𝗵 𝗶𝘁? 𝗔 𝗹𝗼𝘁𝗅 You can read the reports. You can read a summary of each report! You can listen to a podcast version of each report! You can read a “story” or listen to a podcast based on all 18 reports! Whatever is most valuable to you, and all in our “𝗬𝗼𝘂𝗿 𝗖𝗹𝗶𝗺𝗮𝘁𝗲 𝗧𝗼𝗼𝗹𝗯𝗼𝘅” knowledge solution. Link below in the comments.

I responded:

Can you compare these alarming reports with the litany of failure of doomist predictions?

No response.

I tried again some time later in response to Trexler’s adulation for “Wallace Broeker’s seminal paper in Nature” depicting the human influence on climate as playing “climate routlette.”

And [Wallace Broeker] and so many other alleged Malthusian experts have been proven wrong decade after decade. Again, check out the much more extensive list at WUWT, the world’s most viewed website.

The list compiled at WUWT, the world’s most viewed website, is a monument to exaggeration and expert failure (a term popularized by Roger Koppl in his book by the same title). Once again, the realists are beating the alarmists on climate change, but as has been the case with other issues related to human population on a ‘finite’ earth. Julian Simon lives!
