Synopsis: Every first and third Monday of the month, The Straits Times analyses the beat of the changing environment, from biodiversity conservation to climate change. With each passing year, more and more carbon dioxide is pumped into the atmosphere, raising the global temperature. The race is now on to rapidly cut carbon emissions to limit the pace of global warming. But it’s clear that more will need to be done. Huge amounts of CO2 will also have to be removed from the atmosphere, alongside slashing fossil fuel use and ending deforestation.  In this episode, The Straits Times’ environment correspondent Audrey Tan and climate change editor David Fogarty discusses the growing importance of CO2 removal technology with Dr Oliver Geden, Senior Fellow at the German Institute for International and Security Affairs and a lead author for the UN's top climate science body, the Intergovernmental Panel on Climate Change, or IPCC. Dr Geden is an expert on CO2 removal methods and he explains some of the different types and costs and why planting trees alone will not be enough.  Highlights (click/tap above): 1:23 What is carbon dioxide removal?  3:07 Why is planting trees alone simply not enough? 5:48 What are some other examples of carbon dioxide removal strategies?  7:38 What are the range of costs for various carbon dioxide removal measures?  Produced by: Audrey Tan ([email protected]), David Fogarty ([email protected]), Ernest Luis and Hadyu Rahim Edited by: Hadyu Rahim Subscribe to Green Pulse Podcast series and rate us on your favourite audio apps: Channel: https://str.sg/JWaf Apple Podcasts: https://str.sg/JWaY Spotify: https://str.sg/JWag Google Podcasts: https://str.sg/J6EV  Website: http://str.sg/stpodcasts Feedback to: [email protected] Follow Audrey Tan on Twitter: https://str.sg/JLMB Read her stories: https://str.sg/JLM2 Follow David Fogarty on Twitter: https://str.sg/JLM6 Read his stories: https://str.sg/JLMu --- Discover ST's special edition podcasts: Singapore's War On Covid: https://str.sg/wuJa The Unsolved Mysteries of South-east Asia: https://str.sg/wuZ2 Stop Scams: https://str.sg/wuZB Invisible Asia: https://str.sg/wuZn --- Discover more ST podcast series: Asian Insider: https://str.sg/JWa7 Health Check: https://str.sg/JWaN In Your Opinion: https://str.sg/w7Qt Your Money & Career: https://str.sg/wB2m SG Extra: https://str.sg/wukR #PopVultures: https://str.sg/JWad ST Sports Talk: https://str.sg/JWRE Bookmark This!: https://str.sg/JWas Lunch With Sumiko: https://str.sg/J6hQ Discover ST Podcasts: http://str.sg/stpodcasts Discover BT Podcasts: https://bt.sg/pcPL Follow our shows then, if you like short, practical podcasts! #greenpulse See omnystudio.com/listener for privacy information.
