L'activité humaine n'est pas la source principale du réchauffement climatique, loin s'en faut.
La conférence de Bali travaille sur des données dépassées :
Three Stages of Knowledge and the IPCC
Our scientific understanding of global warming has gone through three stages:
- 1985–2003
Old ice core data led us to strongly suspect that CO2 causes global warming.
- 2003–2007
New ice core data eliminated previous reason for suspecting CO2. No evidence to suspect or exonerate CO2.
- From Aug 2007
Know for sure that greenhouse is not causing global warming. CO2 no longer a suspect.
The IPCC 2007 report (the latest and greatest from the IPCC) is based on all scientific literature up to mid 2006. The Bali Conference is the bureaucratic response to that report. Too bad that the data has changed since then!
