Climate change has profound effects on the world's oceans. Rising temperatures lead to thermal expansion and ice melt, causing sea levels to rise. Ocean acidification occurs as seawater absorbs excess carbon dioxide, endangering marine life like coral reefs and shellfish. Altered temperatures disrupt ecosystems, affecting migration patterns and endangering species. Extreme weather events, intensified by climate change, lead to coastal erosion and habitat loss. Additionally, warmer waters can intensify hurricanes and typhoons.
