Climate change in sight: experts discuss responsibility and solutions
On Wednesday, July 9, 2025, the “AlterPerimentale” lecture series will take place at the Brandenburg Technical University Cottbus-Senftenberg. The event is entitled “The climate is saved. Or is it not?” and begins at 5:30 p.m. in the Central Lecture Hall Building (ZHG), Lecture Hall A. Participation is free of charge and open to anyone interested, which is intended to promote dialogue about essential issues of climate change, such as b-tu.de reports.
The guests are welcomed by Prof. Dr. Gesine Grande, President of the BTU. The discussion will be moderated by Dr. Maria Reinisch, Managing Director of the Association of German Scientists. V. The main speaker, Prof. Dr. Hartmut Graßl is a prominent climate researcher with extensive experience in global climate research. Among other things, he was director of the World Climate Research Program (WCRP) and made crucial contributions to various commissions in the German Bundestag.
Issues and challenges of climate change
The focus of the discussion is on reliable information as well as uncertainties and controversial topics surrounding climate change. A central concern will be the responsibility of science and its communication. It also discusses what role an aging society can play in creating a sustainable world.
Current facts about climate change show that global warming is now around 1 degree Celsius above pre-industrial levels. This change is mainly due to human activity, which results in serious damage. Despite 30 years of international climate policy, greenhouse gas emissions continue to rise, as the German Weather Service found in a recently published collection of facts. This highlights the urgency of taking effective measures to protect the climate ( dwd.de ).
The Paris Climate Agreement aims to limit global warming to below 2 degrees. But experts warn that the later action is taken, the harder it will be to avoid irreversible changes. Therefore, the need for structural changes in all areas of society, including the energy system and infrastructure, is undisputed.
The role of science in the climate debate
There is widespread consensus in the scientific community about man-made climate change. Studies show that 90-100% of climate experts support the consensus that affirms human influence on global warming ( klimafacts.de ).
A comprehensive analysis by James Powell suggests that of 33,700 scientific authors, only 34 disputed the consensus. This demonstrates the overwhelming support in the scientific community for the recognition that human activities have a significant impact on the climate. Despite sporadic differing opinions, these usually remain scientifically unfounded and cannot refute the technical findings.
The event at the BTU not only offers a space for discussions about climate change, but also serves to strengthen the role of science as a mediator of knowledge and responsible communication. It is part of a long-term project that will be completed in June 2026 with a total of six lectures on the topic of aging, funded by the Federal Ministry of Education and Research in cooperation with the Association of German Scientists.
