ESA dixit:

“Atmospheric carbon dioxide is the most important human-made greenhouse gas responsible for global warming. Oceans assist in removing carbon dioxide from the atmosphere: phytoplankton accumulate carbon dioxide through photosynthesis and their chlorophyll colours the ocean’s waters. Satellites use this colour to measure chlorophyll, which helps scientists to calculate how much carbon dioxide is absorbed or emitted.”
