Ocean contains 60 times more carbon than the atmosphere

 The ocean contains 60 times more carbon than the atmosphere. The ratio of carbon dioxide (CO2) in the atmosphere to the ocean is affected by a number of factors, including:

Ocean absorption: The ocean absorbs about 30% of the world's CO2 emissions. However, the rate at which the ocean absorbs CO2 has decreased over the last decade.

Climate change: Warmer oceans dissolve less CO2, which reduces the ocean's ability to absorb CO2.

Ocean capacity: The ocean's capacity to absorb CO2 is finite. 

Here are some recent measurements of CO2 in the atmosphere and ocean:

Atmosphere

In May 2023, the average level of CO2 in the atmosphere was 424 parts per million (ppm), which is more than 50% higher than pre-industrial levels. 

Ocean

The concentration of total dissolved inorganic carbon in the surface waters of the North Atlantic is about 2 mmol kg–1. 

The National Oceanic and Atmospheric Administration (NOAA) publishes monthly figures for atmospheric CO2 concentrations.
