Gloabl carbon dioxide sinks. 3D visualization showing the complex patterns by which carbon dioxide in the atmosphere increases, decreases and moves around the globe with the seasons and the weather. Blue areas are below average (CO2 absorption), while red-yellow areas are above average (CO2 accumulation). The visualisation covered the period from September 2014 to September 2015. This still image shows the levels of carbon dioxide on 12 September 2014. Carbon sinks are present on land and in the oceans. This model of carbon dioxide levels was produced by NASA's Global Modeling and Assimilation Office using data from the Orbiting Carbon Observatory-2 (OCO-2) satellite.
