S1E78: How humans are changing the oceans: Green Pulse

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. In May, the World Meteorological Organisation released a report that detailed how four key climate change indicators set new records in 2021. Three of them relate to the ocean: sea level rise, ocean heat and ocean acidification.  Global mean sea level reached a new record high in 2021, the upper 2,000m of the ocean is warming at a rate that is irreversible on timescales of hundreds to thousands of years, while the open ocean pH - a measure of acidity - is likely to be the lowest it has been for at least 26,000 years. Greenhouse gas concentrations also reached a new global high in 2020, when the concentration of carbon dioxide - the main greenhouse gas driving climate change - reached 413.2 parts per million globally, or 149 per cent of the pre-industrial level. In this episode, The Straits Times environment correspondent Audrey Tan and climate change editor David Fogarty discuss the role of the ocean in keeping our planet cool, with Professor Benjamin Horton, a climate scientist and director of the Earth Observatory of Singapore at the Nanyang Technological University.  Highlights (click/tap above): 01:57 How important is the ocean to the global climate?  03:00 Does climate action matter, when climate impacts like sea level rise are irreversible?  07:00 What are the impacts of a warmer ocean?  11:55 Why is the ocean becoming more acidic?  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 #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! #greenpulseSee omnystudio.com/listener for privacy information.
