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.
Supports continued operation of the iconic measurement series
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
Global mean temperatures have been flat for 15 years despite the increase in heat-trapping greenhouse gases, but a new Scripps study shows cooling in the equatorial Pacific Ocean explains the discrepancy
So we’ve reached 400 ppm.… Now what happens?
