Climatology Of Tornadoes In Kansas, John P. Wasinger, Todd Moore
Climatology Of Tornadoes In Kansas, John P. Wasinger, Todd Moore
SACAD: John Heinrichs Scholarly and Creative Activity Days
Recent studies report changes to the climatology of tornadoes in the United States (US). Changes with the most supporting evidence include an increase in the intra- and inter-annual variability, increased concentration of tornadoes in bigger outbreaks, and a geographic shift of the densest tornado activity away from Tornado Alley in the Great Plains and toward the Great Lakes and Southeast regions of the US. Broad, national-level changes are valuable, but they can mask changes occurring at the state and sub-state levels where mitigation efforts are most effective. Kansas is of interest due to its reputation as a hotbed of tornado …
Changes In Reef Tourism’S Adaptive Capacity After Severe Climate Disturbances, Henry Bartelet, Michele Barnes, Lalu Bakti, Graeme S. Cumming
Changes In Reef Tourism’S Adaptive Capacity After Severe Climate Disturbances, Henry Bartelet, Michele Barnes, Lalu Bakti, Graeme S. Cumming
Quantitative Methods and Information Technology Faculty Publications
Knowledge about adaptive capacity and its determinants has increased significantly over the last decade. However, most research on adaptive capacity has been static, not considering how adaptive capacity might change over time, particularly after severe disturbances. We studied the adaptive capacity dynamics of Asian-Pacific reef tourism operators affected by coral bleaching and tropical cyclones compared with a control group with non-affected operators. We found that impacts from tropical cyclones were associated with frequent changes in adaptive capacity. Notably, we found a reduction in tangible attributes (assets and flexibility) of adaptive capacity, whereas intangible attributes (agency and social organization) increased. Our …
Predicting The Potential Distribution Of Pseudococcus Longispinus (Targioni-Tozzetti) (Hemiptera: Pseudococcidae) In South Korea Using A Climex Model, Su Bin Kim, Soo-Jung Suh
Predicting The Potential Distribution Of Pseudococcus Longispinus (Targioni-Tozzetti) (Hemiptera: Pseudococcidae) In South Korea Using A Climex Model, Su Bin Kim, Soo-Jung Suh
Insecta Mundi
Pseudococcus longispinus (Targioni-Tozzetti) (Hemiptera: Pseudococcidae) is a widely-distributed pest that feeds on many economically important hosts, particularly tropical fruits and ornamentals. The potential distribution of this mealybug pest in South Korea remains a primary concern because of its high incidence of interceptions screened during inspection. Hence, this species prompted a modelling effort to assess its potential risk of introduction. Potential risk maps were developed for this pest with a CLIMEX model based on occurrence records under environmental data. The potential distribution of these pests in South Korea in the 2020s, 2050s and 2090s was projected based on the RCP 8.5 …
Interactive Effects Of Co2, Temperature, And Nitrate Limitation On The Growth And Physiology Of Marine Cyanobacterium Synechococcus Sp. Ccmp 1334, Alyssa K. Sharbaugh
Interactive Effects Of Co2, Temperature, And Nitrate Limitation On The Growth And Physiology Of Marine Cyanobacterium Synechococcus Sp. Ccmp 1334, Alyssa K. Sharbaugh
LSU Master's Theses
The marine cyanobacterium Synechococcus sp. CCMP 1334 was grown in a continuous culture system on a 12:12 h light:dark cycle at all combinations of low and high pCO2 (400 and 1000 ppmv, respectively), nitrate availability (nitrate-limited and nutrient-replete conditions), and temperatures of 21°C, 24°C, 28°C, 32°C, and 35°C. The maximum median nutrient-replete growth rate was ~1.15 d−1 at 32 –35°C. Median growth rates at 1000 ppmv pCO2 were higher than those at 400 ppmv at all temperatures, but most of the differences were statistically insignificant. Carbon:nitrogen ratios were independent of pCO2 at a fixed relative growth rate but decreased with …

In a recent paper, we extended a previous study on the solar solar influence to the generation of the March 2012 heatwave in the northeastern USA. In the present study we check the possible relationship of solar activity with the early March 2012 bad weather in northeast Thrace, Greece. To this end, we examined data from various remote sensing instrumentation monitoring the Sun (SDO satellite), Interplanetary space (ACE satellite), the Earth’s magnetosphere (Earth-based measurements, NOAA-19 satellite), the top of the clouds (Terra and Aqua satellites), and the near ground atmosphere. Our comparative data analysis suggests that: (i) the winter-like weather …

In California (CA), the wildland-urban interface (WUI) faces escalating challenges due to surging population and real estate development. This study evaluates communities along CA's WUI that have witnessed substantial population growth from 2010 to 2021, utilizing demographic data and the 2020 WUI boundaries by the University of Wisconsin-Madison SILVIS Lab. Employing the Mann-Kendall test, we analyze yearly population trends for each census tract along the CA WUI and assess their significance. House ownership, affordability, and wildfire risk are examined as potential drivers of this demographic shift. Our findings indicate that 12.7% of CA's total population now resides in census tracts …

Mangroves are one of the most carbon-dense forests on the Earth and have been highlighted as key ecosystems for climate change mitigation and adaptation. Hundreds of studies have investigated how mangroves fix, transform, store, and export carbon. Here, we review and synthesize the previously known and emerging carbon pathways in mangroves, including gains (woody biomass accumulation, deadwood accumulation, soil carbon sequestration, root and litterfall production), transformations (food web transfer through herbivory, decomposition), and losses (respiration as CO2 and CH4, litterfall export, particulate and dissolved carbon export). We then review the technologies available to measure carbon fluxes in …
Differential Impacts Of Weather Anomalies On Household Energy Expenditure Shares: A Comparison Of Clustered Panel Analysis Methods, Jordan Champion
Differential Impacts Of Weather Anomalies On Household Energy Expenditure Shares: A Comparison Of Clustered Panel Analysis Methods, Jordan Champion
Theses and Dissertations--Agricultural Economics
Recent emphasis on environmental justice has highlighted deficiencies in our energy system that produce disparities in accessibility and affordability for the most vulnerable. Meanwhile, the realities of a gradually warming climate and the onset of a global energy crisis (IEA 2022) have coincidently contributed to spikes in both energy prices and demand. These implications threaten to further exacerbate existing disparities for income-constrained and vulnerable populations, enhancing their risk of falling into prolonged insecurity. To ensure our transition to a just, sustainable future, we must first ensure equitable access to affordable and reliable energy for everyone. Combining household-level panel and state-level …

Results Of Cop27 And Expectations For Cop28, Cecilia Kinuthia-Njenga, Fareed Yasseen
New England Journal of Public Policy
Since 1995, government representatives from around the world have gathered nearly every year for the United Nations Conference of the Parties (COP) to advance work on multilateral agreements and to provide a way forward in tackling the significant challenges of climate change. The last of these conferences took place on November 6–20, 2022, in Sharm el-Sheikh, Egypt.
COP27 brought together more than 35,000 people from across the globe to deliberate on important actions for addressing the climate. Hailed as the “African COP” and “Implementation COP,” it raised expectations that decisions from previous conferences, reflecting the needs and priorities of the …
Joint Global Responsibility Fund For Climate, Conservation, And Communities: A Proposed Innovative Tax-Based Funding Mechanism, Tamar Ron
New England Journal of Public Policy
Nature-based solutions address biodiversity loss, climate change, and societal challenges at the local, national, regional, and global levels. The costs of their conservation, however, are mostly local and national in nature. Confronting the rolling dual crisis of biodiversity loss and climate change requires us to recognize nature’s intrinsic value. Moreover, we must find practical ways for their monetary valuation to be channeled as payment for the services of conservation custodians. It is suggested here to translate the value of natural assets and the understanding of the local costs and global benefits of their conservation, into an innovative and ambitious funding …
The How And Why Of Visual Practice At Un Climate Negotiations, Stéphanie Heckman
The How And Why Of Visual Practice At Un Climate Negotiations, Stéphanie Heckman
New England Journal of Public Policy
In this article Stéphanie Heckman examines the process and outcomes of her graphic recording work and other forms of visual practice in the context of UN climate negotiations, reflecting on three years of collaboration with the UN Climate Change Secretariat, particularly during the eighteen-month Global Stocktake process. After a review of the history and science behind visual storytelling, she analyses one of the graphic recordings made for the third meeting of the Technical Dialogue of the Global Stocktake through the lens of Kelvy Bird’s ‘Levels of Scribing’ model. Drawing on comments from delegates at COP27 in Sharm el-Sheikh, Egypt and …
Solar Radiation Modification Governance In The Context Of Temperature Overshoot, Janos Pasztor
Solar Radiation Modification Governance In The Context Of Temperature Overshoot, Janos Pasztor
New England Journal of Public Policy
As the climate crisis escalates, governments—and recently even those in the wealthier countries in the Global North—are struggling to manage the impacts we are experiencing around the world in frightening abundance, including record-setting temperatures, fires, floods, and glacial and ice melt. Behind closed doors, policymakers are concerned as they contemplate the increasing likelihood, even under the most ambitious emission reduction pathways, that the world will overshoot the goal agreed upon in the Paris Agreement to limit global average temperature rise to 1.5oC beyond pre-industrial levels.
It is in this “overshoot context” that interest is growing in an emerging, potentially supplementary …
Cop27 And The New Rise Of The Global South, Janice Golding
Cop27 And The New Rise Of The Global South, Janice Golding
New England Journal of Public Policy
Developing countries require direct and indirect financial and non-financial assistance to address the climate crisis. The COP27 announcement of a new Loss and Damage Fund as well the unveiling of the Bridgetown Initiative collectively hold substantial promise to alter the course of climate multilateralism. The outcome of COP27 has presented unprecedented opportunities for the Global South to build global solidarity for climate justice, but the path ahead will not be easy. Materialization of support to developing countries may be, at best, not sustainable, or at worst, unforeseeable without consistent application of principles and values enshrined in historic, moral accountability for …
The Role Of Carbon Management Technologies In Meeting Net Zero, Ali Al-Saffar
The Role Of Carbon Management Technologies In Meeting Net Zero, Ali Al-Saffar
New England Journal of Public Policy
The pathway toward implementing the changes necessary in the energy sector to keep global temperature rises from breaking through catastrophic barriers is narrow and tenuous and will require a range of zero- and low-carbon technologies to be dispatched at a speed and scale that is virtually unprecedented. Decarbonization through renewables, matched with the more efficient use of energy in the end-use sectors will play a large part. But there is growing realization that there will be residual fossil fuel use long into the future, and that the emissions from the burning of these fossil fuels in power plants and factories …
The Gulf: An Appeal For More Coordinated Action On Climate Change, Fareed Yasseen
The Gulf: An Appeal For More Coordinated Action On Climate Change, Fareed Yasseen
New England Journal of Public Policy
This article seeks to provide the rationale behind Iraqi Prime Minister Al-Sudani’s call at the United Nations for the formation of a negotiating group within the United Nations Framework Convention on Climate Change process that brings together all member states of the Gulf Cooperation Council, Iraq, and Iran. This article argues that these countries would benefit doubly from such an arrangement, because it would help them better address the direct effects of climate change, on the one hand, and to better address the effects of the measures taken to address climate change, which will affect them as fossil fuel producers, …
“Without Water, Nothing”: Examining The Water Saving Practices Of Women In Amman Under Periodic Water Supply, Rory Dixon
“Without Water, Nothing”: Examining The Water Saving Practices Of Women In Amman Under Periodic Water Supply, Rory Dixon
Independent Study Project (ISP) Collection
Jordan is among the most water-scarce countries in the world. Consequently, water is only pumped to households once a week and households store water in tanks to last them until the next water day. Women conducting housework do so under conditions of environmental stress that this research calls resource-scarce domestic labor. In this study, I apply an eco-feminist lens to examine the water-saving practices women employ to manage and conserve domestic water supplies. I explore the larger causes of these behaviors including climate change, government management, and regional politics. Resource-scarce domestic labor is not a practice unique to Jordan and …

There have been many scientific advances regarding future sea-level projections, however it is unclear if these have been transferred to assessment reports used by stakeholders. Here, we present a first-of-its-kind comprehensive analysis of regional sea-level rise (SLR) assessments for the United States (U.S.). We identify variations in time horizons over which regions plan for SLR, with 25 projections from the U.S. Northeast and West that extend to 2150 or beyond, but no projections from the U.S. South beyond 2100. The majority of 2100 projections from the U.S. Northeast (77%) and West (83%) include ranges of future SLR, while 88% of …

Quantifying The Economic Costs Of Global Warming, Christopher W. Callahan
Dartmouth College Ph.D Dissertations
Climate change poses a threat to the well-being of people across the globe. Rising global temperatures will increase the frequency and magnitude of extreme climate events, threatening the lives and livelihoods of vulnerable people. Yet the magnitude and persistence of these economic impacts are poorly understood, making it difficult both to design equitable mitigation and adaptation strategies and to hold emitters accountable for the impacts of their emissions. In this thesis, I combine methods from detection and attribution, climate projection, and causal inference to understand the global economic consequences of past and future climate change. I show that two extreme …

Research outputs 2022 to 2026
* The response of Posidonia oceanica meadows to global warming of the Eastern Mediterranean Sea, where the increase in sea surface temperature (SST) is particularly severe, is poorly investigated. * Here, we reconstructed the long-term P. oceanica production in 60 meadows along the Greek Seas over two decades (1997–2018), using lepidochronology. We determined the effect of warming on production by reconstructing the annual and maximum (i.e. August) SST, considering the role of other production drivers related to water quality (i.e. Chla, suspended particulate matter, Secchi depth). * Grand mean (±SE) production across all sites and the study period was 48 …

Sea Ice Formation, Glacial Melt And The Solubility Pump Boundary Conditions In The Ross Sea, Brice Loose, Sharon Stammerjohn, Peter Sedwick, Stephen Ackley
OES Faculty Publications
Seasonal formation of Dense Shelf Water (DSW) in the Ross Sea is a direct precursor to Antarctic Bottom Water, which fills the deep ocean with atmospheric gases in what composes the southern limb of the solubility pump. Measurements of seawater noble gas concentrations during katabatic wind events in two Ross Sea polynyas reveal the physical processes that determine the boundary value properties for DSW. This decomposition reveals 5–6 g kg−1 of glacial meltwater in DSW and sea-ice production rates of up to 14 m yr−1 within the Terra Nova Bay polynya. Despite winds upwards of 35 m s …

Institute for ECHO Articles and Research
Extreme weather events including wildfires and hurricanes are becoming increasingly hazardous due to climate change, and often result in transient or permanent population displacements. Disaster-related disruptions in infrastructure, workforce, wages, and social networks can combine with population displacements to result in interruptions in health care access and prolonged impacts on morbidity and mortality. The data needed to make health systems and emergency management approaches more resilient to these hazards, and more responsive to the needs of affected populations, are sequestered in silos across private corporations and public agencies. In two case studies, we describe how our research team at CrisisReady …

United States Geological Survey: Staff Publications
Pyrethroids, a class of commonly used insecticides, are frequently detected in aquatic environments, including estuaries. The influence that salinity has on organism physiology and the partitioning of hydrophobic chemicals, such as pyrethroids, has driven interest in how toxicity changes in saltwater compared to freshwater. Early life exposures in fish to pyrethroids cause toxicity at environmentally relevant concentrations, which can alter behavior. Behavior is a highly sensitive endpoint that influences overall organism fitness and can be used to detect toxicity of environmentally relevant concentrations of aquatic pollutants. Inland Silversides (Menidia beryllina), a commonly used euryhaline model fish species, were exposed …
Regenerative Agriculture Framework For Island Ecosystems Using São Miguel As A Case Study, Mya Hunter
Regenerative Agriculture Framework For Island Ecosystems Using São Miguel As A Case Study, Mya Hunter
Independent Study Project (ISP) Collection
Context: Regenerative agriculture is a farming approach that uses soil health as the entry point to contribute to multiple objectives, such as improved nutrient cycling and climate regulation. Farmers can apply different practices to reach these objectives. The objectives and practices, however, are not equally relevant or applicable for farming systems on island ecosystems and the local context.
Objectives: The main objective of this paper, therefore, is to find out how solutions towards regenerative agriculture can be identified and evaluated as such that they result in meaningful advice for farmers on island ecosystems in order to mitigate the …
