CO2.Earth relies on institutional science sources for much of the data and information that is found on this website.   CO2.Earth would not be possible without the resource-instensive 'earth monitoring' and publishing by scientists and the institutions they work for.  This page acknowledges data sources that are frequently used at the site.  The list that follows is not comprehensive. 


Climate Interactive


Climate Interactive is a not-for-profit organization based in Washington, DC, that, among other activities, publishes a Climate Scoreboard and projections for atmospheric CO2 and other greenhouse gases.


Climate Research Unit (CRU)


In the UK, the Climate Research Unit at the University of East Anglia (with the Hadley Centre at the UK MET Office) publishes data for global and hemispheric temperature averages.


Global Carbon Project (GCP)


The Global Carbon Project publishes the following:




In the USA, NASA Goddard Institute for Space Studies (GISS) reports global surface temperature data




In the USA, the Earth System Research Laboratory at the U.S. National Oceanic and Atmospheric Administration (NOAA) reports trends in atmospheric carbon dioxide and other greenhouse gases.




In the USA, the National Climate Data Center (NCDC) at the National Oceanic and Atmospheric Administration (NOAA) reports:

Note: NCEI is replacing NCDC for data access.




In the USA, NOAA's National Centres for Environmental Information (NCEI) provide public access to one of the most significant archives of environmental data on earth. NCEI partners include:


Scripps Institution of Oceanography (SIO)


In the USA, Scripps Institution of Oceanography publishes data for atmospheric greenhouse gases, including CO2.  Data is accessed by two websites and one social media feed:


Skeptical Science (SkS) produces graphics and information that you can find referenced on many CO2.Earth pages. These are mostly secondary sources that communicate scientific information for people of different levels of scientific knowledge.  Among the many resources the site makes available, a team of translators makes a number of articles and graphics available in a number of languages.

SkS is recommended as an excellent resource for checking skeptical claims and beliefs that humans are not causing global warming, or that scientists have made tehcnial errors.


More Data Lists posts a catalogue of data sources, plus a "start here" primer.  They are another good starting point if you are looking for authoritative data sources.   RealClimate is a commentary site on climate science by working climate scientists
