This is a special issue of Science of Climate Change, which contains summaries from the 17th International EIKE Climate and Energy Conference, IKEK-17, which took place in Halle, Germany, June 26 – 27, 2026.
Science of Climate Change is an independent, peer-reviewed and fully open-access scholarly journal devoted to advancing scientific understanding of the Earth’s climate system and its gov- erning processes. It welcomes original research articles, review papers, methodological studies, data analyses, essays, commentaries and scholarly discussion covering climate variability and change across different spatial and temporal scales. Its scope extends across atmospheric sciences, meteorology, hydrology and water resources, land-atmosphere interactions, oceanic and cry- ospheric processes, paleoclimate, remote sensing, climate-data analysis, Earth-system modelling, and solar and astronomical influences on climate.
The first EIKE conference took place in Berlin in 2007, and since then there have been 16 big and many other smaller meetings.
The Conference was arranged by EIKE, Europäishes Institut for Klima und Energie, together with The Heartland Institute (USA) and CFACT, Committee for a Constructive Tomorrow (USA).
There were 164 participants, and the list of 20 speakers was impressing, starring famous interna- tional top scientists such as Nobel Laureate John F. Clauser, Willie Soon, Jonathan Cohler (also a world class musician) Henrik Svensmark, William Happer, Nicola Scafetta, Ronan Connoly and David Legates. And, Michael Limburg, talking this year about how water vapor controls the cli- mate, also spoke during the very first EIKE conferences!
Our journal Science of Climate Change was very well represented on the conference, with both the new Editor-in-Chief Prof. Nikolaos Malamos and a board member of the SCC Publishing Association and one of the former Chief Editors, Prof. Jan–Erik Solheim. Our representatives met with and had talks with many of the speakers and conference participants.
In this volume, you will find the Conference Program, the Table of Contents for this volume, an editorial as well as summaries from nearly all of the speakers. EIKE is cooperating very closely with the SCC Publishing Association and will cover the printing cost of Vol 6.3.
