My Thanks to Ned Nikolov, who has just sent the first part of the ‘Response to comments on the Unified Theory of Climate’ to us.
Part 1: Magnitude of the Natural ‘Greenhouse’ Effect
Ned Nikolov, Ph.D. and Karl Zeller, Ph.D.

We’ve decided to split our expanded explanation into two parts, so that we do not overwhelm people. From what we’ve seen on the blogs so far, there appear to be 2 main areas of confusion: 1) the size of the GH effect. Most people have a hard time wrapping their minds around the fact the atmosphere boosts the surface temperature by well over 100K; and 2) the physical nature of the pressure-controlled thermal enhancement. Although, this follows seamlessly from the gas law, most people (including PhD scientists) appear to be totally confused as to how precisely the effect of pressure works or is even possible. So, this will be topic of our reply Part 2.
(a) The term Greenhouse Effect (GE) is inherently misleading due to the fact that the free atmosphere, imposing no restriction on convective cooling, does not really work as a closed greenhouse.
(b) ATE accurately conveys the physical essence of the phenomenon, which is the temperature boost at the surface due to the presence of atmosphere;
(c) Reasoning in terms of ATE (Atmospheric Thermal Effect) vs. GE (Greenhouse effect) helps broaden the discussion beyond radiative transfer; and
(d) Unlike GE, the term Atmospheric Thermal Effect implies no underlying physical mechanism(s).
We start with the undisputable fact that the atmosphere provides extra warmth to the surface of Earth compared to an airless environment such as on the Moon. This prompts two basic questions:
(1) What is the magnitude of this extra warmth, i.e. the size of ATE ? and (2) How does the atmosphere produce it, i.e. what is the physical mechanism of ATE ? In this reply we address the first question.

Please try to focus on the content of the pdf in comments to this thread. We can carry on posting our general thoughts about the overall theory and how best to formulate our understanding of the proposed gravity effect on the existing threads – thanks.
