The IPCC is Just Politics – Not Science

Fiction: The IPCC is Just Politics – Not Science

The IPCC 4th Assessment Report (2007) is the result of 2500+ scientific expert reviewers, 800+ contributing authors, and 450+ lead authors from 130+ countries. IPCC WGI, WGII, and WGIII Reports are scientific summaries written by scientists. The review process is illustrated below:

IPCC Procedure

From the IPCC Website:

Despite strong political reasons for them not to endorse, the following countries endorsed the IPCC 2007 reports because the science was undeniable:

The IPCC WGI Report (2007) concluded: “Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations.”

130 countries endorsed the reports, and since 2007, no scientific body of national or international standing has maintained a dissenting opinion.




I highly recommend watching the NSF video series linked above to get a very good overview of the IPCC.
