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.”

Dr. James E. Martin, curator of paleontology and research professor in the School of Geosciences, has completed excavation of a 7 million-year-old camel in South-Central Oregon this week.

"We are hoping to have it ready for the next big paleo display that will open at the Lafayette Science Museum next April," Martin said.

The specimen is the most complete skeleton known of the giant camel, Megatylopus, a creature that was 12-14 feet tall and functioned much like the giraffe.

The partial skeleton will arrive in a few weeks to Lafayette, where it will be prepared and placed on display as part of the third installment of the Prehistoric Giants exhibit presented by UL Lafayette and the Lafayette Science Museum downtown.

“It took two months to excavate and encase the specimen in plaster for shipment. We’ll have a unique fossil specimen,” Martin said.

The University's Geology Museum moved to the Lafayette Science Museum in 2013.

With the first in a three-part dinosaur exhibit, attendance doubled in 2014.

The museum includes over 3,000 square feet of exhibit space for fossils, minerals, and rocks, and a 1,500-square-foot research space for students and faculty. It houses the University's collection of fossils, rocks and minerals; features a laboratory to process specimens; and offers new learning opportunities for the public.
