Climate scientists reveal secrets: How our weather is changing!

Climate scientists reveal secrets: How our weather is changing!

On Saturday, March 1, 2025, exciting presentations on climate research took place in the Bielefeld knowledge workshop. In the “Knowledge Happen” series, three scientists from Bielefeld University spoke about central topics that are intended to further sensitize and educate the public. The event lasted from 3:00 p.m. to 4:30 p.m. and was open to adults and young people aged 14 and over. Registration was not required.

The Bielefeld Knowledge Center (Wiii) has set itself the goal of making science accessible to everyone and reducing prejudices towards scientific topics. With a space of 2,800 square meters that includes exhibitions, event areas and workshops, the Wii offers a platform for interactive knowledge transfer.

Stations of the event

The event included three stations that highlighted different aspects of climate change:

• Dr. Annette Christine Möller von der Fakultät für Wirtschaftswissenschaften sprach über Wettervorhersagen, deren Genauigkeit und die Regenwahrscheinlichkeit in Wetter-Apps.
• Professor Dr. Walter Pfeiffer, Dekan der Fakultät für Physik, erläuterte die Bedeutung und Festlegung von Kipppunkten im Klimasystem.
• Professor Dr. Frank Riedel, geschäftsführender Direktor des IMW, beleuchtete den Zusammenhang zwischen Klima und Wirtschaft sowie die Bedeutung von Robustheit bei Anpassungsmaßnahmen.

Climate research and its challenges

Climate research plays a crucial role in unraveling the mechanisms and effects of climate change. Thanks to technological innovations and international collaborations, progress has been made in the collection and analysis of climate data. These developments provide new insights into the dynamics of the Earth system and enable more precise predictions about climate changes, such as the knowledge reported.

Global warming, driven by greenhouse gases such as CO₂, methane and nitrous oxide, is already having far-reaching effects on ecosystems. As a consequence, sea levels are rising, precipitation patterns are changing and extreme weather events are becoming more frequent. The consequences are worrying not only for the environment, but also for human health and global agriculture.

At a time when the need for measures to mitigate and adapt to climate change is becoming increasingly urgent, international cooperation and political action are essential. The aktuell.uni-bielefeld.de reports on the necessary steps for a sustainable future, including decarbonizing energy supplies and promoting sustainable agricultural practices.

Future outlook

Projections for sea level rise by 2100 vary between 0.5 and 1 meter, with pessimistic scenarios predicting up to 2 meters. At the same time, the frequency and intensity of extreme weather events will continue to increase. Meeting these challenges requires both local and global efforts to reduce emissions and develop resilience strategies.

Overall, the event in Bielefeld shows how important it is to raise awareness of the challenges of climate change and how essential collaboration between science, society and politics is in order to shape a sustainable future.
