Note on Pause in Daily Readings

Readings of CO2 from Mauna Loa have been unavailable for two weeks.

According to technicians with the Scripps CO2 Group, the problem is a disk failure that handles the data buffering, which has broken the data stream and valve switching that impacts daily calibration.  The air data are recoverable, because the computer onboard the actual instrument is still working and taking air data, but we will need to assess the stability of calibration once the instrument is working completely again.  A replacement was shipped last week, so it should be up again shortly.

Why Has a Drop in Global CO2 Emissions Not Caused CO2 Levels in the Atmosphere to Stabilize?

Note: Readers have asked why there has been no stabilization in the measured levels of the greenhouse gas carbon dioxide in the atmosphere when reported emissions of CO2 have fallen. Scripps CO2 Group Director Ralph Keeling gave this response: Continue reading Why Has a Drop in Global CO2 Emissions Not Caused CO2 Levels in the Atmosphere to Stabilize?

Video: Charles Keeling (1928-2005) and NOAA’s Mauna Loa Observatory

This short video produced by NOAA tells the story of how Charles David Keeling of Scripps Institution of Oceanography, UC San Diego, worked with scientists from the U.S. Weather Bureau and NOAA at NOAA’s Mauna Loa Observatory to create what is now an iconic record of carbon dioxide in our atmosphere. The measurements of carbon dioxide in the atmosphere taken from 1958 to the present have become the most widely recognized record of mankind’s impact on the Earth, linking rising levels of carbon dioxide from man’s burning of fossil fuels to the warming of the planet.
