The author questions the methods used by the Intergovernmental Panel on Climate Change (IPCC) which have resulted in predictions such as ice sea loss that field data does not support. He argues that this body ignores feedback factors which, although not fully understood, must be taken into account in forecasting future ecological events.
IPCC plays a critical role in any international effort to reduce the effects of climate destabilization. According to Wikipedia:
Thousands of scientists and other experts contribute (on a voluntary basis, without payment from the IPCC) to writing and reviewing reports, which are reviewed by representatives from all the governments, with a Summary for Policymakers being subject to line-by-line approval by all participating governments. Typically this involves the governments of more than 120 countries.
The IPCC does not carry out its own original research, nor does it do the work of monitoring climate or related phenomena itself. A main activity of the IPCC is publishing special reports on topics relevant to the implementation of the United Nations Framework Convention on Climate Change (UNFCCC), an international treaty that acknowledges the possibility of harmful climate change. Implementation of the UNFCCC led eventually to the Kyoto Protocol.
