Swiss Science Seeks Answers To Climate Change In Antarctic Ice

(MENAFN- Swissinfo) Researchers at the University of Bern are studying some of the oldest ice samples on the planet using a revolutionary technique. Their goal is to shed light on one of the major mysteries of Earth's climate. This content was published on October 1, 2025 - 09:00 9 minutes

I cover climate change and energy through reportages, articles, interviews and in-depth reports. I am interested in the impacts of global warming on everyday life and solutions for an emission-free planet. Passionate about travel and discovery, I studied biology and other natural sciences. I have been a journalist for SWI swissinfo for more than 20 years.

My work is focused on making videos and podcasts about science and technology topics. I specialize in developing explainatory video formats for mobile viewing, mixing animation and documentary styles. I studied filmmaking and animation at Zurich University of the Arts and began working as a video journalist at SWI swissinfo in 2004. Since then I have specialised in creating different styles of animation for our visual products.

Florian Krauss walks briskly. He has no time to waste. In a thermal bag he carries an ice rod the size of a bar of soap – too precious to be compromised. It's a unique ice sample, dating back over 1.2 million years.“There's no room for error, but it's exciting to work with such special ice,” he says.

Krauss, a researcher at the University of Bern, retrieved the ice from a room kept at -50°C at the Institute for Climate and Environmental Physics. It's the only ice core facility in Europe that can maintain this temperature and was designed to store ancient fragile ice cores.

The collection includes samples taken last January in Antarctica at a record depth of over 2,500 metres. They are being preserved as part of the European project Beyond EPICA – Oldest IceExternal link . The project's goal is to analyse ice that was formed more than a million years ago to better understand how the climate has changed and, in the long run, to better assess the human impact on climate.
