We know that on average for the global carbon system about half of what humans emit into the atmosphere is removed each year by the land and the ocean. There's details we still don't know, like where that is happening? Different parts of the ocean taking up the carbon dioxide or is the land responding differently? But with the measurements collected from OCO-2, which are about 100,000 good measurements of carbon dioxide around the whole globe every day we can start to answer these questions about the wheres and the whens of the carbon dioxide removal.
