Le GIEC au pays des merveilles

by Drieu Godefridi, 2 mai 2019 in Contrepoints

Réduire le réchauffement global sur Terre de 1,5° ? Dans un récent rapport, le Giec échafaude quatre scénarios pour y parvenir. Mais aucun d’eux ne tient la route.

es quatre scénarios mettent en œuvre à des degrés divers les techniques dites de Carbon Dioxide Removal (CDR), qui compensent les émissions humaines de CO2. Écoutons les experts « scientifiques » du GIEC — dont la plupart ne sont pas scientifiques. Lisons les experts du GIEC :

The recommendation of the Committee on Climate Change (CCC) for a Net Zero emissions target by 2050 is grounded in nothing stronger than irresponsible optimism and arbitrary assumptions about cost and technological feasibility. In point of fact, the technologies seen as necessary, including carbon capture and sequestration (CCS), further expansion of renewable generation, widespread adoption of hydrogen, and the very rapid electrification of the UK’s entire heating and transport systems, are either known failures or are unproven at these scales and would cost two to three times the amounts claimed by the CCC. Attempts to deliver these policies would ultimately fail, but in the attempt the UK would further harm its already declining productivity, and so erode the UK’s ability to compete internationally and thus deliver an acceptable standard of living for its people. This is not a sustainable low emissions strategy, and even if accepted by government is very likely to end only in humiliating and distressed policy correction. A wise government would reject this advice.

A Story of CO2 Data Manipulation

by Tim Ball in A. Watts, May 1, 2019 in WUWT

The consistent pattern of the IPCC reveals demonization and misrepresentations of CO2. Here are some basic facts about CO2 that illustrate the discrepancy between what the IPCC claim and what science knows.

  • Natural levels of Carbon dioxide (CO2) are less than 0.04% of the total atmosphere; it is far from being the most important or even only greenhouse gas as most of the public understands.

  • Water vapour which is 95 percent of the greenhouse gases by volume is by far the most abundant and important greenhouse gas.

  • The other natural greenhouse gas of relevance is methane (CH4), but it is only 0.000175 percent of atmospheric gases and 0,036 percent of all greenhouse gases.

  • In order to amplify the importance of CO2 they created a measure called “climate sensitivity”. This determines that CO2 is more “effective” as a greenhouse gas than water vapour

  • Here is a table from Wikipedia showing estimates of the effectiveness of the various GHGs. Notice the range of estimates, which effectively makes the measures meaningless, unless you have a political agenda. Wikipedia acknowledges “It is not possible to state that a certain gas    causes an exact percentage of the greenhouse effect.”
