The IPCC (The Intergovernmental Panel on Climate Change) published its sixth report about the latest findings about climate change and the news are full of it. Again, fundamental questions about our modern lifestyle arise, which strongly influences our environment. The IPCC-report contains most important information, but not everyone finds time to completely read through the report. In the present article we provide the most important statements of the report.

Every single person has probably imagined once what life as a superhero with special skills would be like. Of course, we all know that most of the skills that actually define superheroes are supernatural and (unfortunately) come entirely from the imaginations of the authors and filmmakers.

About Ice Cores Part III

We have now already learned a lot about ice cores. We know where to find them, how to drill them and how to extract information about the past climate from them. BUT there is still one important piece of information missing. The time stamp. How do we determine how far back in time the ice we hold with our gloved hands comes from? We will see, the ice also uses special languages to encode this secret.

About Ice Cores Part II

In the first article about ice cores, we learned why ancient stories lie dormant in the ice. We got to the icy library and looked at how the stories can be recovered in the form of ice cores. This article will deal with the question how we can reveal the stories of the ice cores. To do this, we need to understand the different languages of the ice.

About Ice Cores Part I

On earth there is a lot of ice and snow and not only in winter – at least at the moment. At the poles there are huge sheets of ice and in between exist many smaller and larger glaciers on high mountains. Stories are preserved in the ice. Stories from long ago. How this happened and how these stories can be brought to the surface, we will learn in this article.

Figure 1: Four dimensions of a nice vehicle. The red volume might be a formula one car while the green volume might represent a rally car.

Have you ever asked yourself why you cannot have a vehicle that is as fast as a rocket, as agile as a formula one car and as robust as a monster truck at the same time? The rocket might be lightning fast, though it will probably fail on tight bends. The formula one car may be quite fast and agile, though it will probably break down quite fast if not carefully driven on asphalt. Well, and a monster truck might be very robust, though it may be slow in comparison. In many fields of research, scientists encounter the same issues as described above. Every new development comes with certain downsides. If you try to satisfy every need, you might get a Jack of all trades, master of none.
