The color of Earth's oceans has changed significantly over the past two decades, and these shifts are the result of human-driven climate change. They cannot be explained by natural variability alone and have affected over 56 percent of our planet's oceans, an expanse larger than the total area of land on our planet.
The color of Earth's oceans are a reflection of the organisms and minerals that lie within its waters. This means, though these color variations may appear subtle to the human eye, they undoubtedly indicate that marine ecosystems are in flux. Although what specific changes are occurring in these ecosystems aren't totally clear as of yet, the team behind the findings is certain human activity and its effects on climate are the cause.
