Oceans cover 70% of the earth’s surface, absorb 90% of excess heat trapped by greenhouse gases, and help prevent dramatic temperature spikes on land. Yet they’re often overlooked in conversations about climate change.
The consequences are significant. Ignoring ocean damage nearly doubles the cost of climate change and has left a multi-trillion-dollar blind spot in climate finance, according to a new study released last week.
Global ocean heat content also increased for the ninth consecutive year in 2025. Every second of last year, the Earth’s oceans absorbed the equivalent in energy to 12 Hiroshima-sized atomic bombs.
Johnny, ICN’s newest staff reporter, pulls back the curtain on these and more of the most interesting developments in the oceans, including the untapped clean energy of the tidal energy industry, which has the potential to provide a carbon-free source of power with complete predictability.

About This Video
Perhaps you noticed: This video, like all the news we publish, is available for free. That’s because Inside Climate News is a 501c3 nonprofit organization. We do not charge a subscription fee, lock our news behind a paywall, or clutter our website with ads. We make our news on climate and the environment freely available to you and anyone who wants it.
That’s not all. We also share our news for free with scores of other media organizations around the country. Many of them can’t afford to do environmental journalism of their own. We’ve built bureaus from coast to coast to report local stories, collaborate with local newsrooms and co-publish articles so that this vital work is shared as widely as possible.
Two of us launched ICN in 2007. Six years later we earned a Pulitzer Prize for National Reporting, and now we run the oldest and largest dedicated climate newsroom in the nation. We tell the story in all its complexity. We hold polluters accountable. We expose environmental injustice. We debunk misinformation. We scrutinize solutions and inspire action.
Donations from readers like you fund every aspect of what we do. If you don’t already, will you support our ongoing work, our reporting on the biggest crisis facing our planet, and help us reach even more readers in more places?
Please take a moment to make a tax-deductible donation. Every one of them makes a difference.
Thank you,
