Climate change

Climate change is affecting our ocean—from coral reefs to the deep sea. Understand climate change’s impacts on people and our ecosystem and how we can all take action to protect the ocean

Human activities are changing our climate in fundamental ways

We’ve already caused the temperature of the Earth to rise by 1.8 degrees Fahrenheit (1.0 degree Celsius) above pre-industrial levels. When we burn fossil fuels, carbon dioxide and other greenhouse gases get stuck in the atmosphere, warming our planet and ocean. These climate changes are making our ocean warmer, more acidic, and less oxygenated—threatening the animals and ecosystems we love.

Climate change impacts people, our ocean’s animals, and ecosystems

The changing climate is affecting the global seafood supply including the people who rely on it. Coral reefs, for example, have been devastated by rising sea temperatures. With less oxygen in the ocean, animals have more difficulty surviving and slower growth rates. Our fisheries feel the burden of a warming planet, as many fish are driven to new habitats.

Solutions to combat climate change and restore the ocean’s health

Reducing carbon emissions, pollution, overfishing, and habitat destruction are the key ways we can help our ocean recover from climate change. Supporting climate change policies on a local, state, domestic, and international level can help us reduce greenhouse gas emissions and protect ocean habitats.
