NOTE:
The Daily CO2 page is now a beta web app.  We are making adjustments as needed to ensure that daily CO2 readings are kept up-to-date and accurate. This work is self-funded and brought to you by a small number of volunteers who are promoting widespread sharing and reporting of CO2 levels.  The purpose is to spur conversations and innovations for stabilizing GHGs in the atmosphere and ending the global climate crisis.  

 

 

CO2 measurements are made by two independent CO2 monitoring programs (NOAA and Scripps) at the Mauna Loa Observatory in Hawaii, about 3400 metres above sea level.  Explore the tabs below where you will see daily CO2 charts and related links.
