The oceans are the most powerful life support system on Earth and they are under threat. In this episode of The Climate Guru, Brent breaks down why the oceans matter more than most people realize. Covering 71% of the planet, the oceans absorb 25% of carbon emissions and more than 90% of excess heat, helping stabilize our climate and prevent extreme global warming. They also produce over half of the oxygen we breathe through phytoplankton and support food systems for more than 3 billion people. But this balance is rapidly shifting. From plastic pollution and agricultural runoff creating massive dead zones, to overfishing, coral reef collapse, and rising ocean temperatures, marine ecosystems are being pushed to their limits. As oceans become more acidic and stratified, the very systems that sustain life are beginning to break down. We also explore rising sea levels, the risk of climate migration, and the growing global effort to protect international waters. The future of the oceans will depend on how quickly we reduce greenhouse gas emissions, transition to clean energy, and rethink our relationship with the natural world. The health of the oceans is not separate from us. It is the foundation of life on Earth. Subscribe for more conversations on climate, environmental justice, and solutions that matter.
