Researchers from the University of Bern are delving into Antarctica\u2019s oldest ice, extracted from a depth of more than 2,500 metres. These samples hold crucial clues to the Mid-Pleistocene Transition, a pivotal period 900,000 to 1.2 million years ago, vital for understanding Earth\u2019s climate future.\n<\/p>\n

\n I lead diverse teams of distribution specialists and multimedia journalists in creating multilingual content for a range of online platforms. I oversee the strategic development of our podcast and video products, driving innovative content creation and audience engagement.
\nAfter training as a broadcast journalist at City University of London, I worked in production and on-air as a journalist or contributor for a range of prime-time TV and radio programmes at top-tier broadcasters including the BBC, NPR, Deutsche Welle, and various commercial networks. <\/p>\n
\n 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. This week on \u2018The Swiss Connection\u2019<\/a> science podcast, we visit the Institute for Climate and Environmental Physics at the University of Bern. Join researchers Hubertus Fischer and Florian Kraus as they unveil their groundbreaking work. They have developed a specialised laser device to meticulously analyse carbon dioxide (CO\u2082) and other greenhouse gases trapped in ancient air bubbles within these ice samples. This innovative approach allows them to reconstruct Earth\u2019s past climate with unprecedented detail.<\/p>\n Fischer and Kraus are integral members of the European project Beyond EPICA \u2013 Oldest IceExternal link<\/a>, an ambitious endeavour aiming to analyse ice formed over a million years ago. Their ultimate goal is to gain a deeper understanding of past climate change and, in turn, better assess humanity\u2019s impact on our planet\u2019s climate.<\/p>\n A key focus of their research is to unravel one of palaeoclimatology\u2019s enduring enigmas: why the rhythm of Earth\u2019s glaciations dramatically shifted around a million years ago, becoming longer and more intense.<\/p>\n Find out more about the \u2018The Swiss Connection\u2019 science podcast and our other Swiss podcasts in English here<\/a>, on\u00a0Apple PodcastsExternal link<\/a>, or\u00a0SpotifyExternal link<\/a>.<\/p>\n \n More<\/p>\n More <\/p>\n Glaciers & permafrost\n <\/p>\n Swiss science seeks answers to climate change in Antarctic ice <\/p>\n This content was published on <\/p>\n Oct 1, 2025 <\/p>\n Researchers in Bern are studying some of the oldest ice samples on the planet.
