What is carbon capture and sequestration? How can this process help reduce CO2 emissions from fossil fuel energy production? What does this process have in common with mayonnaise sandwiches and Rice Krispies? Hosts Robert Mace and Carrie Thompson speak with Senior Research Scientist Dr. Sue Hovorka from the University of Texas at Austin and learn about her work answering these questions and their application in Texas.
In this episode, our hosts cover several topics:
- Robert shares a new word he learned from a meme! [1:15]
- China's climate policies track record in meeting climate goals [2:39]
- Facing the reality of how most of the world's cumulative greenhouse gas emissions have occurred in just the last ten years [6:22]
- The positive effect teleworking and traveling less had on Europe's emissions in 2020 [7:45]
- How Texas cattle ranchers can improve carbon sequestration and water quality [11:46]
- Study shows climate change has made Texas allergies worse faster than anywhere else in U.S. [15:12]
- San Antonio's new pilot project to reduce the urban heat island effect [17:50]
- The potential of adding a new label on foods signifying items with lower carbon footprints and a climatarian diet [22:10]
