Climate Change Impacts Oceans and Marine Life

Oceans cover 71% of the planet’s surface. They make up about 300 times more habitat (by volume) contribute 46% of global primary production and house far more biodiversity and biomass than terrestrial habitats. The oceans are also huge reservoirs for nutrients and gases, including CO2, and ocean currents redistribute heat around the planet, impacting atmospheric [...]
