In my most recent Substack post, Canadian Wildfires, A Long View & A Bear View, I consider the fires burning across parts of Canada, now in July 2026 — about 2.8 million hectares so far, on or below long-term averages — through the lens of forest … [Read more...] about Forests, Peat, and Carbon Markets: Canadian Wildfires and the Long View

Stratospheric Radiative Cooling from CO₂
The stratosphere has been cooling over recent decades as atmospheric CO₂ has risen. This occurs because CO₂ in the cold, thin air of the stratosphere becomes more efficient at radiating infrared energy upward into space. I understand alarmists and … [Read more...] about Stratospheric Radiative Cooling from CO₂
Versions of Science Statement for Reef Protection Taskforce, November 2001
In November 2001, four scientists prepared a science statement for the Queensland Government’s Reef Protection Taskforce. Two versions of that statement exist. The differences between them are significant. The original version, tabled at the … [Read more...] about Versions of Science Statement for Reef Protection Taskforce, November 2001
25 Years Since the Diuron Mangrove Claims – 15 Years Since Our Rebuttal, Still No Correction
What makes the continued sidelining of a 2011 paper that I published with John Abbot so consequential is not simply that one study was overlooked, but that it has allowed a myth to be perpetuated. Do we really want to live in such a society, where … [Read more...] about 25 Years Since the Diuron Mangrove Claims – 15 Years Since Our Rebuttal, Still No Correction
Complicating the IPCC Planck Feedback, Plank #4 of Climate Resilience Theory
The Intergovernmental Panel on Climate Change (IPCC) has an idea about how the Earth cools itself: when the planet’s surface warms up, it sends more heat into space as infrared radiation. They estimate that for every 1-degree Celsius increase in … [Read more...] about Complicating the IPCC Planck Feedback, Plank #4 of Climate Resilience Theory
How Climate Works. In Discussion with Philip Mulholland about Carbon Isotopes
We all know the story about the king who paraded with no clothes, as though everyone watching on was oblivious to the mistake. Parallels can be drawn with sources of CO2, I mean CO2 from factories versus CO2 from natural sources. There is no … [Read more...] about How Climate Works.
