MAUNA LOA OBSERVATORY | CO2 MILESTONES AND CLIMATE CHANGE RESEARCH { 54 images } Created 5 Mar 2013
Explore Jonathan Kingston's photography assignment at Hawaii's Mauna Loa Observatory or MLO on the Big Island of Hawaii. MLO has air sampling towers that have been measuring the carbon dioxide content of earths atmosphere since 1958 thanks to the work of Charles David Keeling and the Scripps Institution of Oceanography. Featured in The New York Times and National Geographic, these images capture the observatory's pivotal role in monitoring atmospheric CO2 levels, leading up to the historic 2013 milestone when concentrations exceeded 400 ppm for the first time.
