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.”

Title:  “The Risks and Rewards of Being First: Drilling the first (non-Pemex) exploration well in Mexico in 78 years”

Date: Thursday, October 26, 2017

Time: 2:00 PM

Place: Louisiane Room (219), Student Union

Abstract:  Loren will give the Keynote address for the AAP and SEG seminar series where he will describe the business rationale for Talos entering into the very first exploration rounds in Mexico and the geological, operational, and business challenges that ensued after winning two exploration blocks. He will also describe the giant field Talos discovered – Zama – and the path forward to develop this vital field for the country of Mexico.

Biography:  Loren Long is the Managing Director – Mexico for Talos Energy LLC, based in Houston. He has been with Talos since August of 2014, but previously worked with the Talos management team at Phoenix Exploration from 2006 to 2011. In 2011, Loren co-founded a private oil and gas company, Momentum Oil & Gas, which produced and explored in South Texas.

Loren Long graduated from Stanford University with a BS in Petroleum Engineering in 1994, and immediately moved to Houston to work for Amoco as a Drilling Engineer. In late 1996, Loren began working for Union Pacific Resources as a production and reservoir engineer in East Texas and the Gulf of Mexico shelf. In 2000, Loren moved back to Houston, where he worked in various engineering positions with Anadarko Petroleum, Houston Exploration, Redman Energy, and Phoenix Exploration.

Loren has been married to Julie for 20 years, and they have four children.
