Climate change is warming up the oceans and changing their water circulation systems. Research off the Peruvian coast has found the declining oxygen level in the water means there is less plankton and there are fewer fish.
Oceans cover more than two-thirds of our planet and give us food, energy and other resources. But worldwide, this fantastic underwater world is in danger. Is there still time to prevent the worst?
Plastic pollution and overfishing may currently be in the headlines. But rising CO2 emissions are also a key threat to the ocean that covers 71 percent of the planet, and a major challenge for future life on Earth.
We tend to associate corals with warm, tropical regions. But there are also species that live in cold, dark, deep waters. What happens to these creatures as climate change warms the ocean and makes the water more acidic?
Coral reefs are dying and there is no global plan to save them…until now. Scientists want to focus on saving 50 of the most important reefs to help them survive climate change.
