Bei den Wetterprofis

ost - 20 Feb 15
24 Stunden und in Echtzeit schauen sie dem Wetter buchstäblich auf die Finger, die Meteorologen. Zu Besuch bei MeteoSchweiz mit Christof Appenzeller, Titularprofessor ETH, im neuen Werkstattgespräch.




Who we are

We are convinced that the sustainable development of a livable world for future generations is one of the core tasks of our society. With our expertise and commitment, our goal is to provide a significant contribution towards solving this task.

Our research

We study the processes and interactions of different environmental systems on various scales, from the molecular scale to global environmental, production and supply systems. The approach of our research is systems-oriented and interdisciplinary.

Agro-ecosystems and world food system  Atmosphere and climate  Biogeochemistry and pollutant dynamics  Ecology, evolution and health  Human and environment  Soil and landuse

What we teach

In our two study programmes, we teach the scientific foundation to analyse complex sound environmental and food systems. Based on a scientific understanding of the problem, students learn to analyse problems and develop solutions to quantitatively evaluate and implement them.

Switzerland must remain integrated in the electricity market


The energy supply in Switzerland in the year 2050 was the focus of a conference organised by ETH Zurich's Energy Science Centre (ESC). One thing was very clear: as far as electricity is concerned, no man is an island any longer. [15.12.2014]

Nitrogen build-up in the oceans


Man-made activities are having a direct impact on the biogeochemistry of the world’s oceans – not only in terms of carbon. Researchers have now shown that also nitrogen compounds released into the atmosphere from combustion processes and agriculture end up in the open ocean. [27.11.2014]

Transforming an avenue in the tropics


What could a section of Calle 30 in the Colombian coastal city of Barranquilla look like in the year 2035? A group of 24 students from four departments at ETH Zurich and Universidad del Norte turned their attention to this question during an exceptional intercultural and transdisciplinary learning event supported by Innovedum. [19.11.2014]

No quick fix for global warming


A debate has broken out between politicians and scientists as to whether atmospheric warming can be delayed by reducing short-lived climate forcing agents. An international research team has now confirmed that a reduction in carbon dioxide emissions is the only long-term remedy for global warming. [04.11.2014]

No-till farming only beneficial in dry regions


Scientists took a closer look at a much-discussed agricultural method, conservation agriculture, and examined its productivity. In a large-scale overview study, they paint a different picture of this less tillage intense farming method: high yields can only be achieved with the method in dry regions. [22.10.2014]
