In the first episode of Season 2, Helen Sharman, Britain's first astronaut, explores how science and technology can help us to manage the polar regions, as melting ice due to climate change opens up shipping lanes, makes resource extraction increasingly viable and throws up environmental and geopolitical issues that affect the whole planet. Helen is joined by Professor Klaus Dodds, Executive Dean for the School of Life Sciences and the Environment at Royal Holloway, University of London. Klaus has extensive experience of working with Governments and commercial stakeholders including the NATO Strategic Foresight Analysis, which assesses trends and their implications to the security environment. The Zero Pressure podcast series looks at how science and technology positively can contribute to solving complex, interrelated global challenges of today and tomorrow. We look at pioneering technologies and speak to those on the thinking edge. Zero Pressure is a podcast from Imperial College London and Saab.
