Climate McCarthyism: No Dissent Allowed! 79-Year old Skeptical Climate Scientist Victim of Witch-Hunt


Dr. Lennart Bengtsson

Climatologist Dr. Judith Curry on Lennart Bengtsson: This ‘has the potential to do as much harm to climate science as did the Climategate emails’ – Curry: ‘We have also seen a disgraceful display of Climate McCarthyism by climate scientists, which has the potential to do as much harm to climate science as did the Climategate emails.’

‘Reminds me about the time of McCarthy’: Climate scientist Dr. Lennart Bengtsson — who converted from warmist to skeptic – resigns from skeptical group after ‘enormous group pressure’ from warmists – Now ‘worried about my health and safety’ – ‘Colleagues are withdrawing from joint authorship’ – Lennart Bengtsson: ‘I have  been put under such an enormous group pressure…Colleagues are withdrawing their support, other colleagues are withdrawing from joint authorship.’ – ‘I would never have expecting anything similar in such an original peaceful community as meteorology. Apparently it has been transformed in recent years.’ – ‘Reminds me about the time of McCarthy.’

[Climate Depot note: The ‘McCarthyism’ was named after Sen. Joe McCarthy. A thorough reading of history may indicate it is an unfair depiction. See here.]

Climate McCarthyism: “Are you now or have you ever been a climate skeptic?” Bengtsson: Science is under pressure because everyone wants our advice. However, we cannot give the impression that a catastrophe is imminent. The greenhouse effect is a problem that is here to stay for hundreds of years. Climate experts should have the courage to state that we are not yet sure. What is wrong with making that statement clear and loudly?’ – ‘The IPCC prediction that with a doubling of CO2 in the atmosphere the temperature on Earth would rise by two degrees should be taken with a grain of salt.’

79-year old skeptical scientist worried about his ‘safety’ – Climate scientist claims he has been forced from new job in ‘McCarthy’-style witch-hunt by academics across the world – Bengtsson believes one of the reasons for this is the US Government’s expanding role on climate change. ‘The public are concerned that recent weather phenomenon have been as a result of climate change. But it is a natural occurrence,’ he said.

UK Times: ‘Witch-hunt’ forces out skeptical climate scientist – ‘The pressure had mainly come from climate scientists in the US, including one employed by the US government who threatened to withdraw as co-author of a forthcoming paper’

‘The Cleansing of Lennart Bengtsson’: Climate Scientist Who Defected To Skeptics Forced to Resign: ‘Reminds me about the time of McCarthy’ – Worried about his ‘safety’

Climate Audit’s Steve McIntyre reacts: ‘Bengtsson’s planned participation in GWPF seemed to me to be the sort of outreach to rational skeptics that ought to be praiseworthy within the climate “community”. Instead, the “community” has extended the fatwa. This is precisely the sort of action and attitude that can only engender and reinforce contempt for the “community” in the broader society.’

Prof. Roger Pielke Jr.: ‘The elite in this community – including scientists, journalists, politicians — have endorsed the climate mccarthyism campaign, and are often its most vigorous participants’ – ‘For experts in the climate issue, there is enormous social and peer pressure on what is acceptable to say and who it is acceptable to associate with. My recent experiences are quite similar to Bengtsson’s’

Climate bullying echoes the expulsion of Mitch Taylor from Polar Bear Specialist Group

Dear Lennart: A Letter In Support Of Professor Bengtsson – David G. Gee – Professor Em. Orogen Dynamics – Department of Earth Sciences – Uppsala University, Sweden: ‘The pressure on you from the climate community simply confirms the worst aspects of politicized science. I have been reprimanded myself for opposing the climate bandwaggon, with its blind dedication to political ambitions; it needs to be exposed, globally.’

Climate Science: No Dissent Allowed


Award-Winning Former UN IPCC Scientist Dr. Lennart Bengtsson Dissents: ‘We cannot yet separate well enough the greenhouse effect from other climate influences’ – Declares climate models ‘more a matter of faith than a fact’

Dr. Lennart Bengtsson

Dr. Lennart Bengtsson: ‘We cannot yet separate well enough the greenhouse effect from other climate influences.’ – ‘Although the radiative forcing by greenhouse gases (including methane, nitrogen oxides and fluorocarbons) has increased by 2.5 watts per square meter since the mid-19th century, observations show only a moderate warming of 0.8 degrees Celsius…high values of climate sensitivity, however, are not supported by observations…Thus, the warming is significantly smaller than predicted by most climate models…since there is no way to validate them (models), the forecasts are more a matter of faith than a fact.’

Top Swedish Climate Scientist Says Warming Not Noticeable: ‘The warming we have had last a 100 years is so small that if we didn’t have climatologists to measure it we wouldn’t have noticed it at all Award-Winning  – Dr. Lennart Bengtsson, formerly of UN IPCC: ‘We Are Creating Great Anxiety Without It Being Justified…there are no indications that the warming is so severe that we need to panic…The warming we have had the last a 100 years is so small that if we didn’t have had meteorologists and climatologists to measure it we wouldn’t have noticed it at all.’

On Monday I was involved in a public panel discussion with Pachauri who insisted that this is an acceleration. I found that I think I know more about this than Mr. Pachauri. The reference above appears to me quite compelling.’

Skeptical Swedish climatology: Dr. Lennart Bengtsson: Global warming only visible under a microscope –  Dr. Bengtsson: ‘The Earth appears to have cooling properties that exceeds the previous thought ones, and that computer models are inadequate to try to foretell a chaotic object like the climate, where actual observations is the only way to go’

The pitch is not accelerated’

‘Climate change has become extremely politicized. The issue is so complex that one can not ask the people to be convinced that the whole economic system must be changed just because you have done some computer simulations’
