From Dr. Tim Ball (climatologist, PhD from Queen Mary University of London): 
When you put the claims of the Intergovernmental Panel on Climate Change (IPCC) in perspective, you get a very different picture that defies logic. I decided to do this because of their recent hysterical claims in Special Report 15 (SR-15) designed to frighten and bully the world into completely unnecessary and enormously expensive environmental and energy policies. Charles Steele summarized their claims and proposed policies in his article, “Climate Doom Ahead? Think Twice,”
“…we have only twelve years to avert climate catastrophe and calls for a fundamental transformation of society and end to the use of fossil fuels. Endorsing it is a critical step towards adopting it, and adopting it would change virtually every element of civil society as we know it today.”
Steele notes that,
“It’s less a scientific report and more a political platform, driven by ideology, not science.”
I agree. Even some members of the IPCC admit it is not about climate but involves an excuse for ideological actions such as a transfer of wealth. However, the majority of the IPCC and its proponents would disagree. They would claim the concern and demand for action are based on science set out in the AR5 Working Group I Report, The Physical Science Basis.
