Carried out in the Atlantic, the findings suggest this ocean absorbs about 7% more CO2 each year than previously thought. It might sound small, but when applied across all oceans, this additional carbon absorption is equivalent to one and half times the carbon captured by annual forest growth in the Amazon rainforest.

The global ocean absorbs about a quarter of humanity's carbon emissions, slowing climate change while also harming the ocean, and the new findings help improve our understanding of these processes.
