Peak carbon dioxide levels surpass 411 parts per million for May
CO2 levels increasing at a faster rate than before
Leader of Keeling Curve measurement says temporary bump from El Niño could push atmospheric CO2 levels above symbolic threshold for good
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.
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.
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. …
Could hit 400 parts per million in January
Tim Lueker, research scientist in the Scripps CO2 Research Group, only needs one sentence to explain why atmospheric CO2 peaks in May.
