An Assessment of the Conventional Global Warming Narrative

by Richard Lindzen

Technical paper 5, The Global Warming Policy Foundation


The one-dimensional picture of the greenhouse effect and the role of carbon dioxide in this mechanism dominates current depictions of climate and global warming. We briefly review this picture. [See attached document.] We then discuss the shortcomings of this approach in dealing with the three-dimensional climate system. One problem is determining what temperature on the real Earth corresponds to the temperature in the one-dimensional treatment. This, in turn, leads to the traditional recognition that the Earth has, in fact, many climate regimes at present. Moreover, there have been profound changes in the temperature difference between the tropics and polar regions over millennia, but at the same time the temperature of the tropical regions has remained little changed. The popular narrative assumes that small changes in the tropics are amplified at high latitudes. There is no basis for this assumption.

Rather, the difference is determined by dynamic heat fluxes in the atmosphere and oceans, with the controlling flux due to baroclinic instability in the atmosphere. Changes in mean temperature are primarily due to changes in the tropic-to-pole difference, and not to changes in the greenhouse effect. The stability of tropical temperatures in the face of strongly varying heat fluxes out from those latitudes points to the existence of strong negative feedbacks in the radiative-convective response of the tropics. Finally, we will comment on the so-called impacts of climate change.

Dr. Lindzen’s assessment addresses the following points:

1. The popular narrative
2. What is the Earth’s temperature?
3. What is the Earth’s climate?
4. What determines the tropics-pole temperature difference?
5. What produces the stability of the tropical temperature?
6. Where does CO₂ fit in the climate?
7. Impacts
8. Where does this leave us?
