Voici la question qui me guide dans mes recherches...

L’appât du gain manifesté par les entreprises supranationales et certains groupes oligarchiques, de même que le contrôle des ressources naturelles par ceux-ci, dirigent l’humanité vers un nouvel ordre mondial de type féodal, voir même sa perte. Confronté à cette situation, l’être humain est invité à refuser d’accepter d’emblée une pseudo-vérité véhiculée par des médias peut-être à la solde de ces entreprises et groupes. Au contraire, il est invité à s’engager dans un processus de discernement et conscientisation afin de créer sa propre vérité par la confrontation de sa réalité nécessairement subjective à des données objectives, telles que révélées par la science, par exemple.

Proxies in climate science - The hockey stick theory is DEAD.

A lot of studies around the climate of the past and prediction of the future is based on the study of proxies. Here a quick definition from Wikipedia.

In climate research, a proxy variable is something that is probably not in itself of any great interest, but from which a variable of interest can be obtained. Temperature proxies such as tree ring widths and ice core layering are used by climatologists to create a temperature record.
To put it in simpler terms... You read the size of tree rings from old trees and deduce with complex equations, past temperatures of the climate where that tree lived.

So how complex is it, for example, the study and extraction of temperature data from tree rings? I invite you to read on the subject here. To put it simply, VERY complex and VERY hard to verify.

On top of that, it seems that the raw data from ring tree proxies used has been "cherry picked" to graph past temperature of the climate.

Again from Wikipedia...
Cherry picking is the act of pointing at individual cases or data that seem to confirm a particular position, while ignoring a significant portion of related cases or data that may contradict that position.

In RED the cherry picked data, in black the full data set.
It will be interesting to follow this subject to see if those studies stand to scrutiny. You can follow more closely here : here and here.

UPDATE: The Bishop Hill blog did a fantastic job of putting this complex story in layman's term. I urge you to read it. You will understand quickly how the data was cherry picked to fit the anthropogenic global warming theory.

In RED the cherry picked data, in black the full data set.

Not a lot of Mass Media has had the courage to publish this new finding... Maybe time will help. But here a few who did:

James Delingpole (Daily Telegraph blog) How the global warming industry is based on one massive lie.

Chris Horner (National Review online) Mann-made warming confirmed

Andrew Orlowski (The Register) Treemometers: a new scientific scandal.

Tom Fuller (San Francisco Examiner) New data questions claims of accelerated warming
