IPCC report ‘not a scientifically rigorous document’ says professor


Not exactly shock news perhaps, but words like ‘extreme’ and ‘unrealistic’ ought to be embarrassing for those who summoned over 20,000 people from around the world to Poland to spend several days discussing it.

London, 20 December: One of Europe’s most eminent climate scientists has documented the main scientific reasons why the recent UN climate summit failed to welcome the IPCC’s report on global warming of 1.5°C.

In a paper published today by the Global Warming Policy Foundation Professor Ray Bates of University College Dublin explains the main reasons for the significant controversy about the latest IPCC report within the international community.

The IPCC’s Special Report on a Global Warming of 1.5°C (SR1.5) was released by the Intergovernmental Panel on Climate Change (IPCC) in advance of the recent COP24 meeting in Katowice, Poland, but was not adopted by the meeting due to objections by a number of governments.

Professor Bates examines some key aspects of the SR1.5 report. He assesses if the IPCC report exhibits a level of scientific rigour commensurate with the scale of its extremely costly and highly disruptive recommendation that carbon emissions be reduced to zero by mid-century.

The paper concludes that such a level of scientific rigour is not present in the report. Specifically, SR1.5 is deficient in scientific rigour in the following respects:

● It departs from the IPCC’s Fifth Assessment Report in conveying an increased sense of planetary emergency without giving rigorous scientific reasons for doing so.

● It fails to communicate to policymakers a considerable body of important observationally-based research evidence that has accumulated since the Fifth Assessment which reduces the sense of a looming emergency.

● It fails to communicate important information made public by climate modellers since the Fifth Assessment regarding the empirical tuning of models to achieve desired results.

The paper concludes that, in view of these deficiencies, the SR1.5 report does not merit being regarded by policymakers as a scientifically rigorous document.

“There is much recent observational and scientific evidence that the IPCC report has failed to include and which supports a more considered mitigation strategy than the extreme and unrealistic measures called for in the SR1.5 report,” said Prof Bates.
