This is a very readable and concise summing up of reasons to be skeptical of the IPCC. I have converted David Henderson’s speech to an html page here
[Note by WSH, this post re-written 24 May. The webpage speech of David Henderson is unchanged]
Summary
David Henderson recently commented on a major presentation by Professor Mohan Munasinghe, a Vice-Chair of the IPCC. He argues that today’s received opinion on climate change issues incorporates three mutually reinforcing and unwarranted
presumptions:
- That the official policy consensus, as widely interpreted today by governments and international agencies, mirrors prevailing scientific opinion and goes no further than it would warrant.
- That prevailing scientific opinion must now be viewed as no longer open to serious question.
- That the process of review and inquiry from which prevailing scientific opinion has emerged, and in particular the IPCC process as its leading element, are professionally above reproach.
In his view, all these beliefs are unfounded. They show a lack of awareness respectively of the present extent of overstatement, overconfidence, and ingrained bias.
Not for the first time, Henderson draws attention to the failure on the part of treasuries and finance ministries across the world to treat climate change issues in an inforrned and resourceful way.
