Climate Solutions (Audio)

As part of the 2022 Carbon Sequestration Symposium at California State University, Bakersfield, Climate Now founder and host James Lawler moderates a panel discussion on how to capture and store carbon dioxide in order to meet climate action goals. The panelists are Ken Haney, California Resources Corporation Bakersfield, Lorelei Oviatt, director of Kern County Planning and Natural Resources and Sarah Saltzer, Managing Director for Stanford Center for Carbon Storage and the Stanford Carbon Initiative.

The 2022 Carbon Sequestration Symposium at California State University, Bakersfield, focuses on engaging the community, industry, policymakers, and academia in the topic of carbon sequestration. According to several studies, Kern County has been identified as a prime location for the geological sequestration of carbon dioxide. Lawrence Livermore National Laboratory's Roger Aines, Ph.D., and Kim Mayfield, Ph.D., discuss efforts underway to capture and store carbon dioxide as a viable option to mitigate climate change.

Using carbon dioxide removal (CDR) strategies to mitigate climate change is a land-intensive endeavor. To capture one gigatonne of CO2 through direct air capture requires a facility & energy production footprint of at least hundreds, but potentially tens of thousands of square kilometers. To capture one gigatonne of CO2 via reforestation requires about 862,000 square kilometers of arable land (nearly the size of the Kalahari Desert). We currently release about 40 gigatonnes of CO2 into the atmosphere every year, so…do the math. And land that is allocated for CDR must compete with other land use claims: for urbanization, agriculture, biodiversity, and renewable energy technologies. But what if our perspective was slightly… more aqueous? Oceans, which make up 70% of the Earth’s surface, already absorb more than 10 billion tonnes of CO2 annually. Would it be more effective to sequester CO2 in the oceans, rather than on land? If so, how would we facilitate increased ocean CO2 uptake safely? What processes and technologies exist today, and how well do we understand them? Series: "Climate Solutions " [Science] [Show ID: 38190]

Climate economists have created a value called the "social cost of carbon" in order to better understand the cost/benefit relationship of climate policies and regulations. The social cost of carbon is the cost to society from damages caused by a ton of CO2 emissions. This value is difficult to quantify, with factors such as future societal wealth and global climate damages (such as species extinction) that are impossible to know.

In order to reach global net-zero emissions by 2050, we must remove CO2 from the atmosphere as well as prevent further emissions. Carbon Dioxide Removal (CDR) can be accomplished naturally -- through forests, soil sequestration, or mineralization -- and technologically. In fact, we will need both natural and technological CDR methods to get to net-zero. So what methods exist that remove carbon from the atmosphere? What are their respective costs, how do they compare, and which are already on the market? Series: "Sustainable California" [Science] [Show ID: 38045]

Climate scientist Julie Kalansky discusses how drought in California and Nevada is a common occurrence, with the attendant water restrictions and threat of severe wildfires bringing the reality of climate change into sharp focus. Future climate projections for the region suggest a trend toward more extremes, including more severe and prolonged drought as well as exceptionally wet years. Learn about the science of drought and how the Scripps-based California Nevada Climate Applications (CNAP) program works to provide drought tracking and early warning in support of drought preparedness and resilience in the face of a changing climate.

The ocean plays a major role in regulating Earth’s temperature through exchange of chemicals and microbes with the atmosphere. When waves break, ocean-derived biological species including viruses and bacteria are transferred into the atmosphere. These species can ultimately form clouds, altering precipitation and climate. Highlights will be presented of novel experiments being conducted in a unique ocean-atmosphere simulator developed by the National Science Foundation (NSF) Center for Aerosol Impacts on Chemistry of the Environment (CAICE). Kimberly Prather, Professor of Climate, Atmospheric Science, and Physical Oceanography at UC San Diego will focus on recent CAICE studies aimed at advancing our understanding of how the oceans influence human and planetary health. New insights will be discussed as well as future studies designed to unravel human versus microbial impacts on the changing Earth’s system.

Researchers at UC San Diego are working on cutting edge technology to combat the constant threat of wildfires in California. The WIFIRE Lab is a collaboration between the Qualcomm Institute and the San Diego Supercomputer Center. The technology uses big data from cameras, weather stations, topography and other sources to quickly predict where wildfires will spread. And, it's not just theoretical. Fire departments like LAFD are actively using WIFIRE to get ahead of blazes before they get out of control. Series: "Computing Around UC" [Science] [Show ID: 35075]

Skyelark Ranch, owned an operated by UC Davis graduate Alexis Robertson and her husband Gillies, uses rotational grazing while raising sheep, which can benefit plant growth, drought resistance, and the climate. The grazing encourages plant growth, which through photosynthesis, captures carbon dioxide from the atmosphere and stores it in the soil, where it can create healthier soils and stay out of our atmosphere.
