Critics of a new United Nations report on global warming say their skepticism is based on discrepancies between the UN’s climate models and actual, observable conditions.

The UN’s Intergovernmental Panel on Climate Change (IPCC) will release its full report on Monday. It expresses 95% certainty that human activity is primarily responsibly for an observed rise in global temperatures over the past century. Environmentalists have said that even mild criticism of such reports on global warming as science “denial.”

Skeptics have already pointed to what they say are flaws in the report’s methodology and resulting problems with its findings.

Past discrepancies between the IPCC’s models and either subsequent environmental conditions or contradictory scientific work at the time demonstrate why those models should not be taken at face value, the critics say.

The IPCC predicted in 1995 that global sea levels would rise by up to 55 centimeters by 2100 “for the range of emissions scenarios.”
