Peak carbon dioxide levels surpass 411 parts per million for May
CO2 levels increasing at a faster rate than before
Scripps Oceanography lab monitoring atmospheric CO2 named National Historic Chemical Landmark
Repost of April 2013 entry The Mauna Loa carbon dioxide (CO2) record, also known as the “Keeling Curve,” is the world’s longest unbroken record of atmospheric carbon dioxide concentrations.
The rate of growth in carbon dioxide concentrations in the atmosphere has accelerated since the beginnings of the Keeling Curve.
In response to a recent reader comment about wide fluctuations in CO2 readings at Mauna Loa, Ralph Keeling and Stephen Walker of the Scripps CO2 Group gave the following answer: It’s fairly normal, especially in the summer time, to see strong afternoon “dips” in the CO2 concentration. The dips are generally caused by upslope winds that that are depleted in …
Scientists make CO2 measurements in remote locations to obtain air that is representative of a large volume of Earth’s atmosphere and relatively free from local influences that could skew readings.
Could hit 400 parts per million in January
Scripps Institution of Oceanography, UC San Diego, Geochemist Ralph Keeling is interviewed for the video series “Climate Changers: Hot Lessons and Cool Solutions.”
Tim Lueker, research scientist in the Scripps CO2 Research Group, only needs one sentence to explain why atmospheric CO2 peaks in May.
