‘The Himalayan glacier melt really was the least of the errors’ – UN IPCC Lead Author Dr. Richard Tol turns on UN: ‘The IPCC does not guard itself against selection bias and group think’ – ‘Alarmism feeds polarization. Climate zealots want to burn heretics of global warming on a stick’

Statement by Dr. Richard Tol

IPCC again


In September 2013, I stepped down from the team that prepared the draft of the Summary for Policy Makers to the Fifth Assessment Report (AR5) of Working Group II of the Intergovernmental Panel on Climate Change (IPCC). This attracted worldwide media attention in April 2014. Regrettably, the story of AR5 became the story of a man.I have been involved with the IPCC since 1994, fulfilling a variety of roles in all three working groups. After the debacle of AR4 – where the Himalayan glacier melt really was the least of the errors – I had criticized the IPCC for faulty quality control. Noblesse oblige – I am the 20thmost-cited climate scholar in the world – so I volunteered for AR5.The Irish government put my name forward only to withdraw its financial commitment when I was indeed elected. The necessary funding could have easily been freed up if the Irish delegation to the international climate negotiations and the IPCC would trim its luxurious travel arrangements.As a Convening Lead Author of one of the chapters, I was automatically on the team to draft the Summary for Policy Makers (SPM). AR5 is a literature review of 2,600 pages long. It assesses a large body of scholarly publication. In some places, the chapters are so condensed that there are a few words per article in the learned literature. The SPM then distills the key messages into 44 pages – but everyone knows that policy and media will only pick up a few sentences.In the earlier drafts of the SPM, there was a key message that was new, snappy and relevant: Many of the more worrying impacts of climate change really are symptoms of mismanagement and underdevelopment.This message does not support the political agenda for greenhouse gas emission reduction. Later drafts put more and more emphasis on the reasons for concern about climate change, a concept I had helped to develop for AR3. Raising the alarm about climate change has been tried before, many times in fact, but it has not had an appreciable effect on greenhouse gas emissions.I reckoned that putting my name on such a document would not be credible – my opinions are well-known – and I withdrew.The SPM, drafted by the scholars of the IPCC, is rewritten by delegates of the governments of the world, in this case in a week-long session …

‘Greens Are Reds’ – ‘And Republicans need to prove it to voters’

They regard industrialization as retrograde, resource extraction as evil, and human beings as net destroyers of the planet. I remember several years ago reading an article by a prominent environmentalist who said Earth’s greatest problem is that mankind has no natural predator.
