Just over a month before the United Nations convenes on September 23 in New York City to discuss climate change and activists gather for a week of action, the Obama White House Council on Environmental Quality (CEQ) argued it does not have to offer guidance to federal agencies it coordinates with to consider climate change impacts...read more

Sebastian Lüning is a geologist, and since 2007 has been the senior geologist with the oil and gas company RWE Dea in Hamburg. He was the 2005/2006 Visiting Professor at the University of Vienna. 
Lünning is the author of several geo-scientific documentaries. He is also the co-author of Die Kalte Sonne (Translated, “The Cold Sun”) with Fritz Vahrenholt. The book claims that global warming is not due to human activity, but rather due to the sun. Interestingly, Vahrenholt is the CEO of RWE.
Lünning also maintains a website for “Black Shale Research” which links back to his website on the Geology of North Africa and Arabia.
Stance on Climate Change
Die Kalte Sonne claims that “global warming over the past 150 years part of a natural cycle that is characterized primarily by the sun.”

DeSmogBlog has done in-depth research on the other speakers and sponsors from Heartland's ICCC9, which can be found here.
May 21 - 23, 2012
DeSmogBlog researched the co-sponsors behind Heartland's ICCC7 and found that they had collectively received over $67 million from ExxonMobil, the Koch Brothers and the conservative Scaife family foundations.
Heartland's president Joe Bast revealed at the end of the conference that the Institute has no plans for future ICCCs. This could be in part due to the defections of corporate sponsors following Heartland's unsuccessful Unabomber billboard campaign and the unintended release of their confidential documents.
“Guest authors” include climate skeptics Henrik Svensmark and Nir Shaviv both who have promoted the theory that the sun drives climate. Other skeptics featured in the book include Nicola Scafetta and Werner Weber. 
Although only recently published, the book has already been found to contain numerous fallacies. See one article debunking published by Zeit Online (translated here). Some of their claims were also refuted by astrophysicist George Feulner. 
A website (in German) titled KalteSonneCheck is also collecting media coverage of the book.
A search of Google Scholar lists 10 articles written by Sebastion Lüning in peer-reviewed journals related to geology and petroleum geology. He does not appear to have published any articles in peer-reviewed journals on the subject of climate change.
