Sources of Data for Graphs World temperature data has been taken from the Goddard Institute for Space Studies, Columbia University, New York (GISS); the Jones, et al. data set from the Climate Research Unit, University of East Anglia, Norwich, UK (CRU); and the Global Historical Climatology Network (GHCN) maintained by the National Climatic Data Center (NCDC) and the Carbon Dioxide Information and Analysis Center (CDIAC) of Oak Ridge National Laboratory, Oak Ridge, Tennessee.
The GISS station page is not easy to find from their home page, but it is found at http://www.giss.nasa.gov/data/update/gistemp/station data/.

Global Historical Climatology Network is maintained at NCDC and CDIAC of Oak Ridge National Laboratory. The home page is http://cdiac. esd.ornl.gov/ghcn/ghcn.html.
Temperature data for the United States comes from the United States Historical Climatology Network (USHCN) maintained at NCDC and CDIAC of Oak Ridge National Laboratory, which states: "We recommend using USHCN whenever possible for long-term climate analyses amp;."
