Peak carbon dioxide levels surpass 411 parts per million for May
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 Scripps Institution of Oceanography, UC San Diego O2 and CO2 programs have received funding from multiple sources that put these operations on a relatively secure footing for the next few years.
The rate of growth in carbon dioxide concentrations in the atmosphere has accelerated since the beginnings of the Keeling Curve.
Breakthrough after field project collects richly detailed ice core records from Antarctica
Supports continued operation of the iconic measurement series
The story of the Keeling Curve is beautifully animated in this new video. The American Museum of Natural History will host a Google+ Hangout Sept. 9, 2014 on the topic of the Keeling Curve. [youtube https://www.youtube.com/watch?v=0Z8g-smE2sk&w=560&h=315]
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.
In a recent comment, a reader posted a graphic in which CO2 and sea-level rise appear to be correlated throughout the last 700,000 years.
