The world's oceans are not immune to the effects of climate change. Rising global temperatures are causing significant changes in ocean ecosystems, with far-reaching consequences for marine life and human societies. One major impact is ocean acidification. As the atmosphere absorbs more carbon dioxide, the oceans also absorb a portion of this gas, leading to an increase in acidity. This acidification disrupts the ability of marine organisms, such as corals and shellfish, to build their skeletons and shells, jeopardizing their survival.

Rising ocean temperatures also disrupt delicate marine food webs. Warmer water can lead to the migration of certain fish populations towards cooler areas, impacting fisheries and coastal communities reliant on fishing for their livelihoods. Additionally, warmer temperatures can trigger coral bleaching, a phenomenon where coral expels the algae living within its tissues, leading to reef degradation. Coral reefs are vital ecosystems that provide habitat for a multitude of marine species and protect coastlines from erosion.
