Climate change is causing glaciers and ice sheets to melt, making sea levels rise. Coastal towns face flooding and erosion. Higher sea levels also increase storm damage and threaten homes, roads, and habitats.

The ocean absorbs carbon dioxide from the atmosphere. This makes seawater more acidic, harming shellfish, coral, and other marine life. Climate change increases the amount of carbon dioxide entering the ocean.

Warmer ocean temperatures stress coral reefs and cause bleaching. Coral reefs provide homes for many ocean animals, but climate change is damaging these important ecosystems around the world.

Plastic waste enters rivers and oceans every day. Climate change and pollution together harm marine animals and ecosystems. Storms and flooding can wash even more trash into waterways.

Many fish populations are shrinking because of overfishing. Climate change changes ocean temperatures and fish migration patterns, making it harder for species to survive and reproduce.

Rising global temperatures are melting Arctic and Antarctic ice. This contributes to sea level rise and threatens animals like polar bears, seals, and penguins that depend on ice habitats.

Warmer water temperatures and pollution can cause harmful algal blooms. These blooms reduce oxygen in the water and can poison marine animals and humans.

Climate change helps invasive species spread into new environments. Some invasive species outcompete native marine organisms and damage ecosystems.

Warmer ocean water gives hurricanes more energy. Climate change can increase the strength of storms, causing flooding, destruction, and coastal damage.

Rising temperatures and pollution destroy habitats such as wetlands, coral reefs, and mangroves. Many ocean animals lose food sources and shelter because of climate change.
