TIMELINE: carbon monitoring<\/p>\n
1957: Charles David Keeling starts work monitoring CO2 at the South Pole and Mauna Loa Observatory, Hawaii<\/p>\n
1958: Keeling starts first direct continuous atmospheric measurements of CO2<\/p>\n
Early 1970s: Noaa, the US federal agency, starts monitoring CO2 worldwide<\/p>\n
1995-2003: Noaa’s Earth System Research Laboratory (ESRL) at Boulder, Colorado, develops and maintains the world’s standard references for CO2 and other greenhouse gases<\/p>\n
