Climate change: the facts

Having had difficulty in locating exact data on the Web, I give a couple of links here, with downloaded copies for backup:

  • Estimates of average temperatures (zeroed to the 1961-1990 averages), monthly from 1850 to 2009, by the Climatic Research Unit (Norwich, UK), http://www.cru.uea.ac.uk/cru/data/temperature/; global land-and-sea averages, compiled on two different algorithms, at hadcrut3gl.txt and hadcrut3vgl.txt, with indications of the percentage of the globe for which data are available in each month.
  • Monthly averages of carbon dioxide concentration as measured at Mauna Loa, March 1958-October 2009, ftp://ftp.cmdl.noaa.gov/ccg/co2/trends/co2_mm_mlo.txt or here.
  • A partial list of the Goddard Institute figures.
