Title: The Economic Superorganism: Beyond the Competing Narratives on Energy, Growth, and Policy
Abstract: Energy drives the economy, economics informs policy, and policy affects social outcomes. Since the oil crises of the 1970s, pundits have debated the validity of this sequence, but most economists and politicians still ignore it. Thus, they delude the public about the underlying influence of energy costs and constraints on economic policies that address such pressing contemporary issues as income inequality, growth, debt, and climate change. To understand why, Carey King will explore the scientific and rhetorical basis of the competing narratives both within and between energy technology and economics.
The competing energy narratives pit “drill, baby, drill!” (fossil fuels) against renewable technologies such as wind and solar. Both claim to provide secure, reliable, clean, and affordable energy to support economic growth with the most benefit to society, but how? To answer this question, we need to understand the competing economic narratives, techno-optimism and techno-realism. Techno-optimism claims that innovation overcomes any physical resource constraints and enables the social outcomes and economic growth we desire. Techno-realism, in contrast, states that no matter what energy technologies we use, feedbacks from physical growth on a finite planet constrain economic growth and create an uneven distribution of social impacts. But we don’t need these narratives, and in fact they distract us, to more accurately understand how the physical basis of the economy is affecting social outcomes.

Title: Paleo-ENSO Variability Changes since Glacial Times
Abstract: While climate models agree that the earth will warm in the future, they do not agree how the El Niño/Southern Oscillation (ENSO) phenomenon will respond to anthropogenic forcing. One method to assess how well models depict ENSO are to force them with geological boundary conditions and compare the results to climate reconstructions. While there are numerous paleoclimate records that can resolve interannual changes, and hence potential ENSO variability from the last 9,000 years, only a handful of paleo-ENSO records exist during the last glacial period, a time of greatly altered mean climate. A series of simulations of deglacial and Holocene climate states performed with the Community Earth System Model, as well as compilations of other climate models run under a subset of similar past climate conditions, suggest that ENSO variability was reduced 6,000 years ago relative to today. Published coral records from the central Pacific agree with models, which were processed using a proxy system model we recently developed, and both datasets show that ENSO variability was slightly reduced 6,000 years ago compared to present, although the data suggest a larger reduction than depicted in the models. The climate models suggest much larger changes in ENSO variability further back in time during the last deglaciation, the Last Glacial Maximum, and during abrupt climate changes when the Atlantic Meridional Overturning Circulation (AMOC) was sluggish. However, little data exists that can resolve ENSO before ~9,000 years ago due to the difficult nature of finding older, pristine samples which are interannually resolved. I will also report on deglacial corals that we collected in Fall 2019 as part of a field trip, where we designed, built, and deployed a prototype drilling system that is portable, cost-efficient, and time-efficient. We deployed to sites in Vanuatu (southwestern tropical Pacific) that have extremely fast uplift and recovered material dated to 10,000 – 15,700 years ago at depths only meters below the surface (< 15 m). We will use these samples to test if ENSO was reduced during glacial times, relative to modern, and if ENSO was more active when AMOC was sluggish, relative to contemporaneous glacial times when AMOC was vigorous, in order to assess how well models simulate paleo-ENSO changes. Preliminary results of corals from the southwestern tropical Pacific suggest that a sluggish AMOC does increase ENSO variability, although longer records are needed to reduce uncertainty in the reconstructions.

Title: A moving boundary framework for the evolution of fluvio-deltaic environments across time scales
Abstract: Theories for stratigraphic interpretation generally describe the architecture and dynamics of fluvio-deltaic environments in terms of sediment supply, tectonics and eustacy, neglecting important factors that could also play a significant role, such as the dynamics of the fluvio-deltaic surface or the accumulation of organic matter via plant growth. In this presentation, I will introduce and discuss a numerical modeling framework aimed to better understand the role of these factors in building fluvio-deltaic architecture. A key aspect of this framework is that it can be treated as a classical heat transfer problem with two geomorphic moving boundaries: the shoreline and the alluvial-bedrock transition. The trajectories of these boundaries over time and space define the evolution of the sedimentary prism geometry, and delimit fundamental transitions in surface morphology and sediment transport regime. We find agreement between the numerical solution and laboratory fume experiments under different scenarios of sediment supply, water discharge, and sea-level changes. In particular, both numerical and laboratory results highlight the importance of the dynamics of the fluvio-deltaic surface in delaying the response of the upstream portion under sea-level cycles. Interestingly, such delay can result in a geologically long-lived decrease in the sedimentation rate in the upstream portion of the profile during sea-level rise and an increase during sea-level fall, suggesting that changes in the upper portion of the fluvio-deltaic surface are not necessarily a good indicator of contemporaneous sea-level changes. Overall, these results demonstrate that numerical techniques from heat transfer, in particular enthalpy methods, can be used to better understand the dynamics of fluvial deltas.

The meltwater generated from these glaciers can take several paths, ultimately discharging into coastal waters or stored in closed-basin lakes. Ice-marginal lakes are a common but poorly understood feature in many glaciated regions, including Greenland. The lakes receive freshwater input from a combination of subglacial, supraglacial, terrestrial and meteoric sources, and a subset periodically drain, resulting in the rapid discharge of large volumes of water downstream (glacial lake outburst floods – GLOFs). In the case of drainages under adjacent marine terminating glaciers, GLOFs can deposit large amounts of sediment, nutrients, and freshwater directly into coastal waters and fjords. Lake Tininnilik, a large (~40 km2) ice-marginal lake that forms along Saqqarliup Glacier in west Greenland, drains ~2 km3 on quasi-cyclic decadal timescales into Saqqarleq Fjord to the north. For this talk, I will discuss the first comprehensive biogeochemical analysis of Lake Tininnilik and its potential influence on coastal primary productivity, including its major and minor nutrient stoichiometry and microbial composition. As the climate continues to warm, GLOFs are expected to become more frequent in Greenland. Therefore, it is imperative that we understand how these events can impact coastal community resilience. |

Speaker: Crispin Little, Professor, School of Earth and Environment, University of Leeds Host: Rowan Martindale Title: Biotic response to environmental perturbations in the Pliensbachian and Toarcian stages of the Lower Jurassic Abstract: The Lower Jurassic period was characterized by instability in global climate, with alternating greenhouse and icehouse states, and episodes of widespread oxygen depletion in the shallow marine environment. These episodes of oxygen depletion are marked by frequent intervals of increased organic carbon preservation in shallow marine sediments. The Pliensbachian stage of the Lower Jurassic was characterised by significantly cooler global temperatures than the preceding Sinemurian, and the following Toarcian stages, and ended with an extinction event (notably for ammonites) at the Pliensbachian-Toarcian boundary (Pl-To) ca. 184.2 Ma. About one Myr later the Toarcian Oceanic Anoxic Event (T-OAE) is characterized Corg rich black shale successions, particularly well developed in sedimentary basins in NW Europe, which display a negative ?13Corg excursion of -5 to -6‰, lasting 0.5 to 1.5 Myr. This excursion has been tied to a disruption of the global exogenic carbon cycle, but the ultimate source of the injected 12C is a matter of debate, with suggestions including methane hydrates, thermogenic methane produced by volcanism in the Karoo-Ferrar Large Igneous Province (LIP), wetlands, and permafrost destabilisation. The onset of the T-OAE in many (but importantly not all) sections is intimately linked to an extinction event that especially impacted the marine benthic macrofauna, but left the nekton largely unaffected. The recovery from this event is not well studied, but in one site, the Cleveland Basin of North Yorkshire, UK, although species richness recovered markedly as soon as environmental conditions ameliorated, other metrics of functional diversity and community structure did not attain pre-extinction levels until much later, some five million years after the extinction event. The talk will be of interest to those working on macroevolution, paleontology, and the effect of large scale climate change on marine ecosystems. |

Master\'s Thesis PresentationsApril, 19 2024Time: 2:00 PM - 5:00 PMLocation: JGB The Master of Science (MS) degree at the Jackson School of Geosciences is considered to be the professional degree for a career in the Geosciences. This degree is the foundation for students pursuing employment in the petroleum industry, environmental and hydrogeological fields, state and federal government agencies, and other related geoscience fields. Some students also use the MS degree as preparation for pursuing a Ph.D. The Energy & Earth Resources Interdisciplinary program provides the opportunity for students to prepare themselves in management, finance, economics, law and policy leading to analytical and leadership positions in resource-related fields. The private sector and government organizations face a growing need for professionals that can plan, evaluate, and manage complex resource projects, commonly international in scope, which often include partners with a variety of professional backgrounds. As requirements for these degrees, students must present a professional talk on Master\'s Thesis Presentations. |
