As climatologists increasingly, albeit grudgingly, concede climate sensitivity to carbon dioxide approaches zero John Elliston publishes a telling paper on the UN’s disastrously wrong definition of a “Greenhouse Effect.” Aussie geoscientist Elliston, pulls no punches with a new study published this week (March 19,2013) by Principia Scientific International (PSI).

In no uncertain terms, Elliston, author of several peer-reviewed papers, concludes that the UN’s Intergovernmental Panel on Climate Change (IPCC) relies on a definition of the “Greenhouse Effect” (AR4,page 946) which is “plain wrong.”
The definition and the accompanying diagrams below are the centerpiece of global warming science: the UN IPCC Assessment Report of 2007.
Elliston’s18-page analysis,‘Why not tell people about the disastrously wrong definition of “Greenhouse Effect” in IPCC Assessment Report 4,2007?’ pulls apart the IPCC’s iconic diagram (AR4, page 115) to reveal fundamental errors (shown below). The cartoon-like diagram is simplified to illustrate the flaws in their “Greenhouse Effect” concept.
Elliston found: “The statement in the definition that downward atmospheric radiation from the cold upper atmosphere “trap(s) heat” in the surface-troposphere system to result in higher temperatures and global warming is untrue.”
He goes on to clarify, “The idea that back-radiation or radiant heat from the very cold upper atmosphere results in increasing the temperature of the warmer air below contravenes at least two elementary laws of physics (Second Law of Thermodynamics and Stefan-Boltzmann Law).”
As Elliston indisputably points out, “cold things like the exceedingly cold upper atmosphere cannot radiate heat to result in warming much hotter air near the ground that is the climate we live in.”
