Marine Environments and Climate Change

The video discusses the significance of Earth's oceans, covering 71% of the planet's surface, and their role in providing essential goods and services. It highlights the impact of climate change on marine life, including rising sea temperatures and ocean acidification, which affect species distribution and marine food webs. Human activities further damage marine habitats that capture carbon. The video emphasizes the importance of sustainable marine management and the role of JNCC in building evidence, understanding oceanic contributions to climate mitigation, and collaborating internationally to address climate challenges.
