How does rising sea temperatures and levels affect marine life?

Rising sea temperatures can have negative effects on the development and growth of marine organisms. Increasing ocean temperature could alter oceanic currents, impacting the migration and reproduction of some marine species, and causing coral bleaching. When oceanic currents change, they impact the migratory patterns of marine species, as well as the reproduction of species such as reef-building coral and reef fish which rely on these currents to disperse larvae.

Sea levels are rising at alarming rates and pose threats to invaluable marine ecosystems.
Sea-level rise is accelerating at a rate of one-eighth of an inch per year. This poses a threat to coral reef, mangrove and seagrass ecosystems.
