isramart: Current Data for Atmospheric CO2

isramart news:

The world's most current data for atmospheric CO2 is from measurements at the Mauna Loa Observatory in Hawaii. These high-precision measurements were started by Dave Keeling (shown in the photo) in March 1958.

Today, the monthly average concentration of CO2 in the atmosphere is published by the National Oceanic and Atmospheric Administration (NOAA) within a week after each month ends. The source data is organized into a table and republished here at CO2Now.org so more people can see the latest CO2 level and the important CO2 trend. The table includes the full Mauna Loa instrument record for atmospheric CO2.
