Helen Czerski, an ocean physicist and Associate Professor at UCL, dives into the complexities of our oceans. She dispels the myth that we understand them less than the moon, highlighting their intricate ecosystems and unique interspecies relationships. Czerski discusses the challenges of traditional physics in studying ocean dynamics, stressing the role of temperature and salinity in creating distinct layers. She underscores the impact of human activities on these vital systems and calls for advancements in ocean science to ensure a sustainable future.

Helen Czerski, a physicist and oceanographer at University College London, dives deep into the ocean's role in climate regulation. She discusses how oceans absorb a third of our CO2 and 90% of excess heat. The conversation explores ocean physics, marine ecosystems, and the importance of understanding oceanic health in addressing climate change. Czerski highlights the risks posed by rising temperatures and human activities, urging a re-evaluation of our connection with oceans not merely as resources but as vital life support systems.

Physicist Helen Czerski and journalist Tom Heap discuss rewilding efforts and balancing human needs with nature's preservation. They explore bison reintroduction impacts, agricultural conservation in North Norfolk coast, and the harmonious relationship between humans and the environment.

The deepest parts of the Pacific Ocean have been largely unexplored for centuries. But now the ecosystem thousands of metres beneath the surface is under threat - from companies wanting to mine the seabed for rare metals and minerals.The proposals to allow deep-sea mining are centre-stage at global talks by the International Seabed Authority - the UN body in charge of regulation - and its members in Jamaica in the coming weeks. It comes after a two-year ban on the practice expired when countries failed to reach an agreement on new rules. Scientists fear a "goldrush" for precious metals beneath the oceans could have devastating consequences for marine life. But supporters argue that these metals are needed if the world is to meet the demand for green technologies - such as electric car batteries - that will be key in the fight against climate change.So is this a necessary step in the journey towards cleaner, greener technologies? Does climate change pose a bigger risk to our oceans overall? And what impact might mining have on this rare and delicate ecosystem?Shaun Ley is joined by:Pierre Josso, mineral geoscientist at the British Geological SurveyHelen Czerski, physicist and oceanographer at University College London and author of 'Blue Machine: How the ocean shapes our world'Toby Fisher, environment lawyer who has negotiated with the International Seabed AuthorityAlso featuring: Gerard Barron, CEO of The Metals CompanyPhoto: An animal from the deep Pacific Ocean known as a 'gummy squirrel'.

Tim Marshall, a global affairs journalist and bestselling author, teams up with Helen Czerski, a renowned science communicator and physicist, to delve into the intricate relationship between geography and global politics. They discuss how geography shapes geopolitical conflicts, highlighting Russia's ambitions regarding Crimea and the strategic importance of regions like Taiwan. The conversation emphasizes the critical role of historical context in understanding current tensions and the influence of geographic factors on international relations and decision-making.

Dr. Helen Czerski, an oceanographer and physicist, and Dr. Justin Burton, a physicist focusing on giant bubbles and fluid mechanics, dive into the whimsical world of bubbles. They explore how to make colossal bubbles, including the feasibility of encasing the Earth. Fun anecdotes reveal NASA's role in bubble record-breaking and the chemistry behind stable bubbles. The duo also investigates bubbles in zero gravity as a potential climate solution, showcasing their vital role in oxygen absorption and carbon dynamics in oceans.

The podcast discusses Banksy's new mural in North London and the debate over deep-sea treasure hunting. They explore the environmental impact of mining valuable metals on the ocean floor, as well as Greenpeace's exclusion from an environmental forum. The episode also delves into historical analysis of whales' earwax records and ends with listener feedback and an interview recap.

Physicist Helen Czerski and guests explore the impact of waste on the environment. They discuss the potential to reduce greenhouse gas emissions by utilizing all resources, address the fashion industry's waste problem, and the challenge of tackling global waste management. They highlight the importance of innovative solutions and responsible consumption to combat the waste crisis.

Journalist Tom Heap and physicist Helen Czerski discuss the urgency of addressing climate change and declining wildlife populations. They explore human impacts on nature and the need for a change in how we interact with the planet, emphasizing the role of individuals in shaping a sustainable future.

Helen Czerski, British physicist, oceanographer, and presenter for the Fully Charged Show, discusses her new book 'The Blue Machine' which explores the significance of the ocean, the impact of climate change on the poles, the importance of decarbonizing, the alarming increase in sea temperature, diving in the London Aquarium, the bioluminescent communication of the Humboldt squid, and the environmental impact and accountability of deep sea mining.
