For Vincent Courtillot, geophysicist and director of the Institute of Earth Physics in Paris, human activities are not responsible for climate change. And the Copenhagen conference will only be a means of putting down Western economics.
According to Giec's work, emissions of CO2, related to human activity, largely explain global warming. Why do you refute this finding?
Climatology is a beautiful science, but it is still young and very complicated. When IPCC experts say they are “90%” sure that CO2 is the main culprit in global warming, they are going beyond what they can say. Because this hypothesis has not been demonstrated. In our scientific group, we believe that it is above all the sun which is responsible for this warming. The average temperature of the globe has been falling for ten years, which has also been the case for the temperature of the sun. In our opinion, carbon dioxide is not responsible for the climatic observations of the 20th century.
Your work upsets a very broad scientific consensus.
Unlike Claude Allègre, we first kept silent because we wanted to publish our work in scientific journals. It is done. I was first called a negationist! But let me come back to this famous consensus. At first, I thought it was the result of scientific work. In reality, it is the result of a vote. It is very different! Remember the welcome physicist Wegener received when in 1915 he established his theory of continental drift. In 1960, the top 2000 geologists said that continents did not drift. Ten years later, the "consensus" had reversed. It took 53 years ...
For you, the debate is far from closed ...
When we say that there is no more debate, in a field as complicated as the climate, we are no longer in the domain of science, but of religion. 200 years ago, I would have already burned ...
What do you expect from Copenhagen?
It is very likely that China, and therefore the United States, will do nothing. It will remain the good soldier Europe, which will be in the foreground, while it releases only 1% of greenhouse gas emissions. But be careful: I never said that we should not save oil and reduce greenhouse gas emissions. What I'm saying is that doing it by putting the economy of the western world down is not reasonable.
