The IPCC has issued the 2013 report on global Climate change. The skeptic community has effectively challenged the IPCC primary positions. This post will provide a broad selection of those challenges for the reader to examine. Each of the 18 entries will give you the title, a brief synopsis, and the link to that document.
The IPCC failed on two major issues. Their failed to explain why global temperatures have not increased in the past 16 years despite a continued growth of atmospheric carbon dioxide (CO2). The second issue is that of climate sensitivity. They did say that in the past, they had overestimated climate sensitivity but did not tell us what they now believe it to be. This posting will also cover climate model performance and should the IPCC be discontinued.
