Peak carbon dioxide levels surpass 411 parts per million for May
April monthly average exceeds 410 parts per million for the first time in recorded history
We are now approaching the annual low point in the Mauna Loa CO2 curve, which typically happens around the last week of September but varies slightly from year to year.
A hurricane bearing down on Hawaii prompted operators to shut down CO2 monitoring equipment at Mauna Loa Observatory on the Big Island.
A failed disk that had prevented the reporting of daily readings was replaced on June 14 and the system is now running normally.
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 …
On Nov. 5, 2015, we made an adjustment to the Scripps Mauna Loa CO2 record that has the effect of increasing concentrations we have reported since April 2015
The rate of growth in carbon dioxide concentrations in the atmosphere has accelerated since the beginnings of the Keeling Curve.
Question submitted to Scripps Oceanography science magazine explorations now by Ruben M., Watsonville, Calif. Great question Ruben! The surface temperature we experience every day is not expected to perfectly track CO2 because CO2 isn’t the only factor driving climate change. Still, it is quite an important factor, and the overall rise in temperature does roughly follow the overall rise in CO2. …
