Global Carbon Budget - Ocean Accurate assessment of anthropogenic carbon dioxide (CO 2 ) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere – the “global carbon budget” [...] land sink have approximately balanced. The oceans are therefore the most important net sink for anthropogenic CO 2 emissions. The ocean in the Global Carbon Budget Less than half of all CO 2 emissions remain [...] land sink have approximately balanced. The oceans are therefore the most important net sink for anthropogenic CO 2 emissions. Each year, we collect estimates of the ocean carbon sink from global ocean bi
