More than 50 percent of the world's oceans will shift in color due to climate change by the year 2100, an MIT study has found. Climate change is causing significant changes to phytoplankton in the world's oceans, and over the coming decades, these changes will affect the ocean's color, intensifying its blue regions and its green one, according to the study published in the journal 'Nature Communications'. Derived from the Greek words phyto (plant) and plankton (made to wander or drift), phytoplankton are microscopic organisms that live in watery environments, both salty and fresh. Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow. They developed a global model that simulates the growth and interaction of different species of phytoplankton, or algae, and how the mix of species in various locations will change as temperatures rise around the world. The researchers also simulated the way phytoplankton absorb and reflect light, and how the ocean's color changes as global warming affects the makeup of phytoplankton communities. They ran the model through the end of the 21st century and found that, by the year 2100, more than 50 percent of the world's oceans will shift in color, due to climate change.
