The color of the oceans has altered due to the climate crisis
Approximately 56% of the world's ocean has changed color from blue to green in the last 20 years, according to an analysis of NASA satellite images. The most noticeable change is observed around the equator. The exact cause of this phenomenon is unknown, but it is likely due to an increase in phytoplankton as a result of the climate crisis.
Furthermore, the color of the ocean's water can vary annually, while the level of chlorophyll on the surface remains relatively unchanged. This makes it more difficult to assess the impact of global warming on this process.
To gain a better understanding of these changes, NASA will launch the Pace mission in January 2024. Its objective is to monitor phytoplankton, aerosol emissions, clouds, and ocean ecosystems.
Other scientific assumptions indicate that the color of water can be influenced by factors such as temperature, salinity, and the presence of minerals. Warmer water generally appears more vibrant, while higher salinity levels can result in a greenish tint. Different minerals in the ocean also contribute to variations in color, as specific elements may interact with light in distinct ways.
