This figure shows an overview of global carbon dioxide levels from 2003 to 2015. The colored lines show the average amount of atmospheric carbon dioxide in different latitude bands. For example, the red line shows the average carbon dioxide in the latitude range 30o north to 60o north, over northern hemisphere mid-latitudes. As can be seen, atmospheric carbon dioxide is increasing despite effort to reduce emissions primarily caused by burning of fossil fuel.
The newly released ‘Climate Research Data Package No. 3’ covers more than one decade (2003 – 2014) of atmospheric data products used to get information on the sources and sinks of carbon dioxide and methane. The data products are available through the website: http://www.esa-ghg-cci.org/
