Children's University: Why is our earth getting warmer? And how can we find out?
Volker Michel is a geomathematician and is an expert on climate change and global warming. What do these terms actually mean and how certain is what science says about them? Volker Michel: "In this lecture, we will try to understand how we can find answers to these questions. This involves approaching the matter as scientists do. First of all, we need to look at what we know about temperatures on Earth and how they have changed. Fortunately, the people who study the weather have been writing down their data since about 1850. But we need to look even further back in time, long before reports on the weather were written. And we can actually do that, even without a time machine..."
Fall season: Future energy
In September, the four children's university events revolve around the topic of "Future energy".
Many cars still run on petrol or diesel. And many houses are still heated with oil or gas. This pollutes the air - which is bad for our environment. This produces CO₂, a gas that makes the earth warmer and warmer. This warming is called climate change: there is more frequent heavy rainfall, but sometimes it also rains too little and this leads to drought.
To prevent this from getting worse and worse, we need other sources of energy - so-called renewable energies. This means: energy that comes from natural forces such as wind, water or sun and does not pollute the environment.
But how can we actually turn wind into electricity? And how does water help us to power machines? You can find out with exciting experiments and simple explanations in the fall series of the Siegen Children's University.
