Global Temperature Politics Or Science

This is going to be interesting!

This morning I woke up early and while checking my email, this title caught my attention in Space Daily Express newsletter...

After reading the article, I could not stop my self to post this on the blog although, I have already posted one article yesterday...

"The entire debate about global warming is a mirage", this is the opening statement of the news article. Article talks about fundamental of temperature and different averaging methods and other thermodynamics involved in it.

I am posting some of the statements from the news as it is

"global temperature' is thermodynamically as well as mathematically an impossibility"

"It is generally assumed that the atmosphere and the oceans have grown warmer during the recent 50 years. The reason for this point of view is an upward trend in the curve of measurements of the so-called 'global temperature'."

Even more sound statement

"It is impossible to talk about a single temperature for something as complicated as the climate of Earth", Bjarne Andresen says, an expert of thermodynamics. "A temperature can be defined only for a homogeneous system. Furthermore, the climate is not governed by a single temperature. Rather, differences of temperatures drive the processes and create the storms, sea currents, thunder, etc. which make up the climate".

"while it is possible to treat temperature statistically locally, it is meaningless to talk about a a global temperature for Earth"

I like the analogy here...

"The Globe consists of a huge number of components which one cannot just add up and average. That would correspond to calculating the average phone number in the phone book."

Then the news explains some more on averaging methods and finally, makes statement ...

"The currently used method and the consequences drawn from it therefore is more politics than science"

Here is complete news article

The original research is published in Journal of Non-Equilibrium Thermodynamics with even more interesting title 'Does a Global Temperature Exist? ' by professor Christopher Essex, Ross McKitrick and Bjarne Andresen.

The Complete reference to original artilce is

C. Essex, R. McKitrick, B. Andresen: Does a Global Temperature Exist?; J. Non-Equil. Thermod. vol. 32, p. 1-27 (2007). Journal of Non-Equilibrium Thermodynamics.

Some more about Authors ?

Ross McKitrick He is an economist ...
Christopher Essex He is a mathematician ...
Bjarne Andresen He is a professor of physics
