Seminar on "50 Years of Atmospheric CO2 Monitoring: Lessons and Perspectives" 
Wednesday, 29 August 2012,  3:00 -  4:30
 Hits : 4277 

Dr. Keeling started collecting CO2 samples at Mauna Loa in 1958. By 1960, he had
established that there are strong seasonal variations in CO2 levels with peak levels
reached in the late northern hemisphere winter. In 1961, Keeling produced data
showing that CO2 levels were rising steadily in what became known as the Keeling
Curve". The atmospheric concentration of CO2 has grown from 315 ppm in 1958 to
380 ppm in 2005 with increases correlated to fossil fuel emissions. Other nations
quickly established their own stations in places, especially around North America and
Europe. Today the global network has more than 100 stations and has contributed
enormously to our knowledge of global change. This talk will illustrate the current
network and scienti c perspectives of these measurements.
