CO2 levels now higher than any time in the last 23 million years

One of the most pressing messages that climate scientists attempt to convey to the public is how today’s CO2 levels compare to those of the Geologic past. Such comparisons can provide public context for current CO2 rise, as well as important information on the response of global temperatures to rising CO2. A new study published in Geology suggests that present-day CO2 levels (412 ppmv) are now likely higher than at any time in at least the last 23 million years!

In this newly published study, a team led by Brian Schubert, Associate Professor in the School of Geosciences at the University of Louisiana at Lafayette, used the remains of dead plants to produce a new record of atmospheric CO2 that spans 23 million years of uninterrupted Earth history. Their findings relied on the nearly continuous record of terrestrial photosynthesis provided by organic matter accumulated from partially decomposed plants.

“When plants grow, the relative amount of the two stable isotopes of carbon, carbon-12 and carbon-13, changes in response to the amount of CO2 in the atmosphere,” says Schubert. “One can therefore measure the relative amount of these two isotopes and calculate the CO2 concentration under which the plants grew.”

The Society of Exploration Geophysicists (SEG) EVOLVE program is a noncompetitive hands-on program that exposes students to real-world projects which require integration of seismic, wireline, core, production, and other relevant data. The data analyzed is within the context of exploration, reservoir appraisal, field development planning, and production enhancement scenarios. This year, UL Lafayette graduate students have been selected to participate in the EVOLVE program starting mid-February to May, their dataset will be from Northland Basin in New Zealand. The UL Lafayette team will be given access to the iEnergy and the Halliburton Landmark DecisionSpace Platform. EVOLVE participants are encouraged to collaborate with other teams and ask questions to industry mentors so as to make the most out of the program. In the spirit of collaboration, a graduate student from the University of Arkansas will collaborate with the UL Lafayette team via the cloud based DecisionSpace platform to analyze the Northland Basin data. At the end of the EVOLVE program, the participating teams will give technical presentations of their projects to an executive committee then present at the SEG annual meeting in September 2019 at San Antonio.
