“…data on CO2 cannot be explained by the model of the greenhouse effect as the driver for temperature”

Today’s climate models assume there is a perpetual positive feedback as more CO2 is added to the atmosphere; CO2-induced warming produces more and more warming.

But Dr. Peter Stallinga uses empirical evidence-based data in his 2025 paper to determine the actual feedback sign is negative – and by a factor of two. This destroys the catastrophic runaway warming narrative.

“…feedback [from added CO2] is empirically found to be negative [by a factor of 2]”

The research emphasizes the statistical connection between CO2 and temperature is not consistent, shifting across different time periods or theoretical frameworks. For example, the paleoclimate relationship between CO2 and temperature may be 2000 ppm per K, whereas it is assumed to be 100 ppm per K over the last 60 years.

These wildly divergent relationships suggest that complex, varied physical processes influence the climate system rather than a single, dominant factor (i.e., rising CO2 emissions).

Ultimately, the study concludes that the greenhouse effect alone cannot adequately explain all observed atmospheric data.

“On a contemporary timescale, it is clear why the temperature has risen so little compared to the GHE model; CO2 simply does not have a large enough effect on temperature.”
