Temperature increases have profound impacts on marine ecosystems, primarily through ocean warming, acidification, and altered circulation patterns. Higher temperatures can lead to the bleaching of coral reefs, disrupt breeding patterns of marine life, and affect species distribution, pushing them towards cooler waters. Additionally, altered temperature regimes can disrupt food webs and ecosystem services. These changes threaten biodiversity and compromise the health of marine environments, impacting fisheries, coastal communities, and global economies reliant on healthy marine ecosystems.
