Acidification Beneath The Waves

As carbon emissions climb, the world's oceans absorb more carbon dioxide, putting coral reefs, shellfish, and entire marine ecosystems at risk, calling for urgent mitigation efforts

The world is grappling with the visible impacts of climate change—melting glaciers, rising sea levels, and extreme weather—but an equally urgent, less visible threat is unfolding beneath the ocean's surface. Ocean acidification, often referred to as the "evil twin" of global warming, is a chemical shift in the seas driven by the same carbon emissions that are altering the climate. It is quietly but profoundly changing marine ecosystems, threatening food security, economies, and biodiversity. Unlike many environmental crises that are localized, ocean acidification is global, affecting every corner of the world's oceans and touching countless lives.

The root cause of ocean acidification is excess atmospheric carbon dioxide. When fossil fuels like coal, oil, and natural gas are burned, CO2 is released into the atmosphere; 30% of this is absorbed by the ocean. While this might seem like a natural climate buffer, it comes with a hidden cost.
