  • Throughout this website, references to average or mean CO2 levels for any month or year since March 1958 means data collected by continuous atmospheric monitoring at the Mauna Loa Observatory in Hawaii, USA. At Mauna Loa, the remote location, undisturbed air, and minimal influences of human activity and vegetation are ideal for monitoring consituents in the atmosphere that can cause climate change.
  •  
  • The Mauna Loa Observatory is part of the National Oceanic and Atmospheric Administration (NOAA), Earth System Research Laboratory (ESRL), Global Monitoring Division (GMD) in the USA.  The continuous, high-precision measurement of changes in atmospheric CO2 concentrations was started in March 1958 at the Mauna Loa Observatory by Charles David Keeling.

 

  • The monthly CO2 reading is the most current and comprehensive indicator of how well we are doing, collectively, to address the root causes of global warming and climate change.

 

CO2 is well mixed in the atmosphere, so observations of concentrations from a single site like the Mauna Loa Observatory are an adequate indicator of world trends for atmospheric CO2.

Mauna Loa Science & Wonder

At the end of March 2011, globe-trotting climate photographer Gary Braasch paid a visit to the Mauna Loa Observatory in Hawaii. It didnít take long for Braasch to come away with a stunning set of images and informative commentary.  Check out his photolog, reposted below with permission.  (Or, skip over to Gary Braasch's WorldViewofGlobalWarming.org to see his Mauna Loa science photographs and other climate change photos from around the world.)   It's like getting a personal tour of the world famous observatory and the atmospheric science that happens 24-7 near the top of the mountain, 3.4 kilometres above sea level.  CO2 Vial & Mauna Loa Observatory at Night | Braasch photos
