The Ocean’s Seasonal Exhale: Rethinking the Keeling Curve
I have been meaning to write about this for some time. In May 2025 we posted a preprint that offers a different explanation for one of the most famous graphs in climate science — the Keeling Curve. Our paper is titled ‘A Thermal Acid Calcification … [Read more...] about The Ocean’s Seasonal Exhale: Rethinking the Keeling Curve
How Unstable Power Corrupts Australia’s Temperature Record
Since 1996 the Bureau of Meteorology has been replacing liquid-in-glass thermometers with electronic probes connected to automatic weather stations. The probes do not measure temperature directly; they measure electrical resistance, which is … [Read more...] about How Unstable Power Corrupts Australia’s Temperature Record
Quantifying Uncertainty. Rutherglen Minimum Temperatures & Background Information
AI climate models do not understand atmospheric physics. They learn statistical patterns, relationships and trends directly from the historical records they are trained on. If these data arrays contain industrial scale remodelling — justified by … [Read more...] about Quantifying Uncertainty. Rutherglen Minimum Temperatures & Background Information
Oceans Warm Atmosphere with Meteorologist William Kininmonth – Audio and Summaries
One of my interests is in understanding how and why the climate is so stable, for sure it has been over the last several thousand years. Where I live, on the Tropic of Capricorn, daily atmospheric temperatures may fluctuate by 20C, yet the … [Read more...] about Oceans Warm Atmosphere with Meteorologist William Kininmonth – Audio and Summaries
Average Temperatures and Heat Movement (Part 2)
I should think that when enough time has passed, the current leaders of the free world – but especially the scientists who advise them – will be remembered in the history books as rather deceitful. That after a few hundred years of a period of … [Read more...] about Average Temperatures and Heat Movement (Part 2)
