The Earth's seas and oceans are much more than vast expanses of blue water; they are the planet's ultimate life-support system and largest active carbon sink. As global conversations about climate change intensify, understanding how marine environments process greenhouse gases becomes critical. According to data provided by the United Nations , the world's oceans play a monumental role in regulating global temperatures by capturing massive amounts of carbon dioxide ( CO2 absorption by oceans ). Without this natural buffering capacity, the impacts of global warming would be drastically more severe than what we experience today. In this comprehensive guide, we explore the exact figures, scientific mechanisms, and long-term consequences of how our seas manage atmospheric carbon. The Core Numbers: How Much CO2 Do Oceans Absorb? To grasp the scale of marine carbon capture, we must look at the hard data collected by climate scientists and international environment...
