Long-term observation and research on the ocean floor
The ocean floor is an archive for environmental and climate changes, a unique habitat and an endangered ecosystem all in one. Scientists from the U Bremen Research Alliance are investigating the effects of climate change at the Cap Blanc off the Mauritanian coast. Samples are taken with the help of so-called sediment traps, some of which are anchored at a depth of several thousand meters on the seabed. You can read about the conclusions the scientists can draw from this from page 8 onwards in the article "Long-term observation and research on the ocean floor".
Using wind turbines longer
An important part in the fight against climate change is the expansion of renewable energies. Wind power plays a central role in this. Around 30,000 wind turbines are currently generating green electricity in Germany and are helping to achieve climate targets. How can the service life and safety of wind turbines be increased while reducing maintenance and electricity generation costs as well as CO₂ emissions? The scientists have their sights set on a component that has to endure a lot: the rotor blade bearing (p. 4).
Explaining the climate crisis: Bremen in the Intergovernmental Panel on Climate Change
Climate change is one of the most urgent problems of our time. With that in mind, it is the task of the Intergovernmental Panel on Climate Change to summarize and evaluate the state of research on climate change in order to provide politicians with a science-based basis for their decisions. Three working groups regularly compile global climate knowledge in status reports. In February it's that time again. Then Working Group II presents its partial report. The co-chair of the influential committee - and only the second German scientist in this position - comes from the U Bremen Research Alliance: Professor Dr. Hans-Otto Pörtner, cooperation professor from the Alfred Wegener Institute and the University of Bremen. You can find out more about Bremen’s contribution to the work of the Intergovernmental Panel on Climate Change from page 12 onwards.
