“Characterizing Decadal Variability in a Fickle Climate: New Methods in High-Resolution Paleoclimatology”
Accurately predicting future changes in water stress will require an improved under-standing of Earth’s natural systems and their response to pervasive global change. To that end, our understanding of the oceanic and atmospheric dynamics under continued anthropogenic forcing rests on two major pillars: general circulation models (GCMs) and instrumental climate data. Unfortunately, observations of 20th century climate (e.g., from weather stations or satellites) are too short (back to 1900) to fully characterize decadal and centennial variability in the climate system. To augment the relatively brief instru-mental record, high-resolution paleoclimate data record the pulse of the planet over timescales for which we have no direct records, provide a means for investigating extremes in past climates as an analog for future conditions, and help constrain statistics for climate variability. Future projections of water stress will depend crucially on such improved estimates of variability on longer (decadal to centennial) timescales, which archives of past climate can provide. Thus, to improve predictions of climate system behavior, it is necessary to combine data from models, instrumental data, and high-resolution paleoclimate archives.
To accomplish this combination, data-model comparison is frequently employed to test climate models’ ability to accurately simulate past climates and to help explain excur¬sions in proxy data. Such data-model comparison yields insight into climate system dynamics that remain poorly constrained. However, these comparisons generally employ an inverse approach, relating simulated climate fields (precipitation, temperature) to proxy data (e.g., speleothem calcite or ice cores). These efforts are fraught with uncertainty as proxy records are generally multivariate, seasonally-biased recorders of climate. Furthermore, model-data inter-comparisons often do not explicitly model the effects of age uncertainties, which confound comparisons to current-generation transient climate simulations. Due to these complications, inverse approaches in data-model comparison are fundamentally limited. This talk will highlight improved data-model comparison methodology using proxy system modeling and water isotope physics for applications in past and future extremes in hydroclimate variability.

Evolving Worlds: A Story of Planetary Evolution and Bi-Stability
The Earth is the only body in the Solar System for which significant observational constraints are accessible to such a degree that they can be used to discriminate between competing models of Earth’s tectonic evolution. It is a natural tendency to use observations of the Earth to inform more general models of planetary evolution. However, our understanding of Earth’s evolution is far from complete. In recent years, there has been growing geodynamic and geochemical evidence that suggests that plate tectonics may not have operated on the early Earth, with both the timing of its onset and the length of its activity far from certain. Over the last five years, the potential of tectonic bi-stability (multiple stable, energetically allowed states) has been shown to be dynamically viable, both from analytical analysis and through numeric experiments in two and three dimensions. This indicates that multiple tectonic modes may operate on a single planetary body at different times within its evolution. It also allows for the potential that feedbacks between internal dynamics and surface processes (e.g., surface temperature changes driven by long-term climate evolution) can cause terrestrial worlds to alternate between multiple tectonic states over giga-year timescales. Here, I will briefly discuss the constraints on the tectonic evolution of the Earth and present a framework of planetary evolution that incorporates the potential of tectonic regime transitions and multiple tectonics states being viable at equivalent physical and chemical conditions.

Title: Landform Evolution Rates on the Moon and Mercury
Abstract: When we look at the Moon or Mercury, we see densely cratered surfaces, and it is tempting to think that these airless bodies experience no ongoing erosion or topographic change. However, slow landform evolution is occurring, which, over the course of billions of years, becomes a significant process. By studying the degradation of impact craters, we can infer both the rate at which landform evolution occurs and better understand the underlying processes causing topographic change. The derived rates can then be used to estimate the age of craters, surface units, and other landforms based on their topography. In addition, a comparison with similar measurements on Mercury suggests that it experiences much faster landscape evolution rates than the Moon.

DeFord Lecture | Dr. Richard TaylorApril, 25 2024Time: 4:00 PM - 5:00 PMLocation: Boyd Auditorium (JGB 2.324) Adapting to the Amplification of Climate Extremes Through Freshwater Capture: Evidence from the Tropics by Dr. Richard Taylor, Department of Geography, University College London Abstract: In low-income countries of the tropics undergoing rapid growth, global warming presents challenges to the expansion and sustainability of water supplies required to advance progress toward the United Nations’ Sustainable Development Goals. Substantial uncertainty persists in projections of precipitation under climate change. A widely observed impact, pronounced in the tropics, is the intensification of precipitation comprising a transition towards fewer but heavier rainfalls. How does this transition impact terrestrial water balances? How might these changes influence freshwater demand? I will interrogate these questions and review mounting empirical evidence from the tropics of the resilience to climate change of groundwater resources, which act as a natural inter-annual store of freshwater supporting adaptation to the amplification climate extremes. Presented evidence includes case studies and local-to-regional scale analyses from tropical Africa and the Bengal Basin of South Asia. Outcomes emphasize the interconnected nature of surface water and groundwater as well as the value of groundwater as a natural, distributed store of freshwater. This insight provides a platform to explore more equitable and sustainable water development pathways resilient to climate change. |
UTIG Seminar Series: Cornelia Rasmussen, UTIGApril, 26 2024Time: 10:30 AM - 11:30 AMLocation: PRC 196/ROC 1.603 Speaker: Cornelia Rasmussen, Research Associate, University of Texas Institute for Geophysics Host: Krista Soderlund Title: The Emerging Field Of Position-Specific Isotope Analysis: Applications in chemical forensics, exobiology, geo- and environmental sciences Abstract: Complex organics can be found all over our solar system and within each living thing on our planet, be it as part of its physiology or as a contaminant. However, different processes can lead to the formation of chemical identical molecules. This makes answering a number of scientific questions challenging. One example is distinguishing between biotic and abiotic molecules, hence hindering life detection on early Earth but especially on other planetary bodies, such as on Mars, Titan, Enceladus and on meteorites where organics have been detected. Moreover, tracing molecules as they move through the environment can be demanding, yet is essential in studying the flow of organic molecules as well as correlating pollutants with their source. Novel tools to address these challenges are currently being developed. Especially, the emerging field of position-specific isotope analysis is beginning to grant access to the unique intramolecular carbon (13C/12C) isotope fingerprint preserved in complex molecules. This fingerprint can be applied in various scientific disciplines, ranging from forensics to exobiology, geo- and environmental sciences, including geo health. Nuclear magnetic resonance spectroscopy (NMR) has the potential to become a key player in this research area, as it allows the analysis of organics within complex mixtures, all without the need to fragment the molecule into single carbon units or the combustion of the molecule of interest. We have been developing several NMR tools that allow us to investigate the intramolecular carbon isotope distribution within various molecule classes and to test the central hypothesis that the position-specific carbon isotope distribution within complex organics depends on a molecule’s source and formation history. |
