    Are the Himalayan glaciers at a tipping point?

    The Himalayan glaciers are melting more rapidly as global temperatures rise, raising concerns about the future of ecosystems and communities across the Himalayan mountain range. Glaciers store more than two thirds of the world’s freshwater and help regulate global temperatures by reflecting the sun’s rays. Across South Asia, melting ice is contributing to the formation of unstable glacial lakes and increasing the risks of floods, droughts and avalanches. The Himalayas are a vital source of water for millions of people, supporting agriculture, energy production and livelihoods from tourism. Experts warn that continued glacier loss could have significant consequences for people living in the region and the mountainous ecosystem, but what can be done to respond to these changes? We speak to leading scientists including Pasang Yangjee Sherpa, assistant professor at the University of British Columbia, Canada; Pam Pearson, director and founder of the International Cryosphere Climate Initiative, US; Matthias Huss, glaciologist and senior scientist at the Swiss Federal Institute of Technology Zurich, Switzerland and Alton Byers, faculty research scientist at the Institute of Arctic and Alpine Research at the University of Colorado, US Presenter: Tanya Beckett Producer: Matt Toulson Technical producer: Mitch Goodall Editor: Tom Bigwood (Photo: Trekkers walk to Everest Base Camp in Nepal.

    Should we mine the Moon?

    The recent Nasa Artemis II crewed mission to the far side of the Moon is a further step towards a long-term return to the lunar surface and future missions to Mars. The plan is that before the end of the decade there will be a crewed landing and the start of a Moon base. China is among those developing similar plans. Previous missions both crewed and uncrewed have provided evidence of resources that potentially could be of use here on Earth, and support human life on the Moon. So, it’s not just the race to the Moon that’s capturing the world’s attention, but also the possible economic benefits that that might bring with it. The Moon’s surface or lunar regolith contains volatiles like hydrogen, carbon dioxide and methane. There is evidence of minerals such as silicate and oxides and metals like aluminium and titanium, which could be extracted for building materials. And something that is rare on Earth, Helium-3, a potential resource for clean fusion energy. Governments in conjunction with private corporations are already working on the technology to extract these resources. Concerns have been raised about the potential damage to the Moon, not only in terms of the depletion of its resources, but in terms of its scientific value and its cultural heritage. Protection ranges from established treaties that prohibit ownership of the moon, to national laws that permit resource extraction. But to date, there is no universally accepted international law in place, which explicitly permits or prohibits lunar mining. So, this week on the Inquiry, we’re asking ‘Should we mine the Moon?’ Contributors: Dr Dylan Mikesell, principal geophysicist, NGI-The Norwegian Geotechnical Institute, Oslo, Norway Dr Justin Holcomb, assistant research professor, Kansas Geological Survey, University of Kansas, USA Prof Dr Thomas Zurbuchen, director of ETH Space, Swiss Federal Institute of Technology, Zürich, Switzerland Dr Tanja Masson-Zwaan, assistant professor and deputy director, International Institute of Air and Space Law, Leiden University, The Netherlands Presenter: William Crawley Producer: Jill Collins Editor: Tom Bigwood Sound engineer: Nicky Edwards (Photo: The Moon.

    Is it time to scrap the Commonwealth Games?

    For the second time in 12 years Glasgow is preparing to host the Commonwealth Games after Australia’s Victoria state pulled out because of increased costs. Victoria’s withdrawal raised questions about whether the 2026 games would go ahead before Glasgow agreed to step in. Staging a sporting mega-event is expensive and governments face increasing scrutiny over public spending. Victoria’s decision raised wider questions about affordability for potential hosts. At the same time, critics question the Games’ political relevance, given its origins in Britain’s colonial past. The Commonwealth Games Federation says the event can be delivered in a more sustainable way and argues that it brings cultural and economic benefits to host cities, but recent editions have run into significant costs and budget pressures. Our contributors this week are Dr Stuart Whigham, senior lecturer in sport, coaching and physical education at Oxford Brookes University, UK; Dr Matthew McDowell, lecturer in sport policy, management, and international development at the University of Edinburgh, UK; Dr Verity Postlethwaite, lecturer in strategic event management at Loughborough University, UK and Professor Gayle McPherson, associate dean for research at the University of the West of Scotland, and director of legacy and community engagement for Commonwealth Games Scotland, UK.
