The ocean helps sequester carbon emissions, but it comes with a cost to marine health
- "The ocean takes up CO2 in two steps: first, the CO2 dissolves in the surface water. Afterwards, the ocean’s overturning circulation distributes it: ocean currents and mixing processes transport the dissolved CO2 from the surface deep into the ocean’s interior, where it accumulates over time...By moderating the rate of global warming, the oceanic sink for man-made CO2 provides an important service for humanity, but it has its price: the CO2 dissolved in the ocean acidifies the water. 'Our data has shown that this acidification reaches deep into the ocean’s interior, extending in part to depths of more than 3000 m,' Gruber says. This can have serious consequences for many marine organisms."- Excerpt from ETH Zurich.
