The Heartland Institute’s recent International Climate Change Conference in Las Vegas illustrates climate change deniers’ desperate confusion. As Bloomberg News noted, “Heartland’s strategy seemed to be to throw many theories at the wall and see what stuck.” A who’s who of fossil fuel industry supporters and anti-science shills...

Friedrich-Karl Ewert is an emeritus professor of geophysics at the University of Paderborn. He is also member of the Advisory Board of the German climate change skeptic organization European Institute for Climate and Energy (EIKE).
Stance on Climate Change
“Menschliche Aktivitäten verursachen nicht in entscheidender Weise den Klimawandel,” Translated: “Human activities do not cause climate change decisively.” 
“Contrary to computer based scenarios – and hence contrary to what is generally believed — anthropogenic CO2 is meaningless because its influence is not recognizable. Of course this result complies with the basic laws of physics and is not really surprising.” 
“increasing solar activity” is “probably the reason” for a “slow global warming since the mid-19th century.” 
“The facts are: Ever since the Little Ice Age, we have been warming up again. We don’t have global climate change; what we have are normal temperature fluctuations. We have had parallel cooling and warming episodes. No CO2 influence can be detected. Since 2000, we have been cooling off again. And, data have been manipulated in order to fake a warming trend: Climategate. The IPCC’s scenarios are failures. And in conclusion, ladies and gentlemen, this analysis can be verified—any one of you can do it!” 
Friedrich-Karl Ewert was a speaker (PDF) at the combination eighth International Conference on Climate Change (ICCC-8) and the Fifth International Conference on Climate and Energy (ICCE-5) sponsored by both the Heartland Institute and EIKE. 
His speech is titled “NASA GIS Changes Temperature Data Retroactively – Why?” He gave a speech of the same title on September 17, 2012 at another EIKE-sponsored event. In his previous speech, Ewert implied that NASA is guilty of manipulating temperature records.

Spoke at an event organized by EIKE and the Berlin Manhattan Institute. His presentation was titled “NASA GISS Changes Temperature Data Retroactively – Why?” and suggested that “NASA retroactively altered important temperature data and so led to false results in climate science.”
Ewert claims that The American GISS (Goddard Institute of Space Science) altered temperature data “so that the present can appear to be warmer.”

Ewert was a speaker at EIKE's 4th International Conference on Energy and Climate Change. “[O]ur conference features international top scientists and experts, presenting pressing evidence to reconsider or stop the current policies aimed at 'saving the climate',” reads a description of the event at the Berlin Manhattan Institute. Friedrich-Karl Ewert's speech was titled “Mission impossible - geological facts of carbon capture and storage in Germany.” 
Ewert spoke at a conference in Rüsselsheim, Germany hosted by the Schiller Institute titled “Rescuing Civilization From the Brink.” His speech was titled “The Anthropogenic Climate Change Swindle.” Translated video of the conference is available here. , 
Ewert began: 
“[A]s a geologist, I asked myself, 'What exactly are they telling you about this climate change?' But there’s nothing special about it; we've always had climate change. Temperatures on the Earth have been stable only temporarily, and for the most part they have changed after a short time.”
Ewert spoke at a briefing hosted by CFACT and EIKE which featured presentations that “build upon the analysis of Professor S. Fred Singer and provide information on the geological record, solar activity and the big question — is our climate governed by man or nature?” The briefing was introduced by fellow German skeptic Wolfgang Müller. 
Friedrich-Karl Ewert was a speaker at the 3rd International Energy and Climate Conference hosted by the European Institute for Climate and Energy (EIKE). Other event organizers included the Berlin Manhattan Institute, CFACT, Haus der Zukunft, and Friedrich Naumann Stiftung für die Freiheit. 
Other notable speakers included:
Friedrich-Karl Ewert presented at a press conference by EIKE where he describes why he believes that “Long-term temperature readings disprove man-made global warming.”
According to Ewert, “anthropogenic CO2 is meaningless because its influence is not recognizable.” 
Ewert is one of the principal signatories of an open letter to German Chancellor Dr. Angela Merkel which implored her to “abandon the pseudo-religion of anthropogenic warming.”
According to the letter, “anthropogenic CO2 plays no discernible role [in climate change]. The proportion of radiation absorbed by CO2 is already nearly exhausted by the current concentration. Even if CO2 had an effect and all fossil fuel reserves are burned, would the additional heating term limited to the range of tenths of a degree.”

Friedrich-Karl Ewert spoke at an event at the University of Paderborn. His lecture was titled (roughly translated) “Climate Change - Our CO 2?” and set out to “refute the popular thesis that should decisively human activities contribute to climate change.”

According to the article description: “This article is not a scientific publication. Rather it highlights frequently discussed arguments and current issues regarding the alleged danger of global warming. These key issues are based on real temperature records and field observations. Computer modeling is disregarded.”
