The Intergovernmental Panel on Climate Change (IPCC) has just produced their sixth report. If you disagree with the conclusions of the IPCC report, then you should have a very good reason. You need to fairly and completely represent the evidence, and indicate specifically why the IPCC report is wrong or misleading. None of these claims are credible, and they don’t address the robust evidence on which the IPCC report rests. This IPCC report, however, builds on a solid foundation.
