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 …

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 …

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 …

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

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 …

Climate Change And Legume Performance In Grassland Agroecosystems, Lynn E. Sollenberger, M. M. Kohmann

IGC Proceedings (1977-2023)

We reviewed the literature to assess the effect of climate change factors on forage legumes. Whether growing in monoculture or mixtures with grasses, exposing legumes to elevated CO₂ (eCO₂) generally leads to sustained increases in forage accumulation (FA) and N fixation, but elevated temperature (eT) in conjunction with eCO₂ usually reduces magnitude of these responses. In legumes, nodules represent large C sinks, precluding photosynthetic acclimation to eCO₂ observed in non-N fixing plants. Greater N fixation in legume-grass mixtures exposed to eCO₂ is due to greater percentage of legume N derived from symbiotic fixation and …

Cool-Season Perennials And Stability In Year-Round Forage Production Systems, C. D. Teutsch

IGC Proceedings (1977-2023)

Changes in long-term climate normals have resulted in warmer and wetter summers and milder winters in the humid eastern United States. This will likely impact regional forage species adaptation in the long-term and varietal adaptation in the short term. Variety evaluation has been occurring at the University of Kentucky for almost 100 years. There are several considerations for selecting forage species and varieties including regional and local adaptation, productivity, distribution of growth, palatability, nutritive value, anti-quality factors, tolerance to stress, and persistence. Two of the most important criteria are long-term productivity and persistence under grazing, both of which are currently …

Discrepancies Between Observed And Predicted Climate-Driven Net Herbage Accumulation, Alec D. Mackay, Michael B. Dodd, K. J. Hutchinson, Ronaldo Vibart, F. Bilotto

IGC Proceedings (1977-2023)

The decline in net herbage accumulation (NHA) on the high phosphorus (P) fertilizer farmlet (HF) of a long-term P fertilizer and associated sheep grazing experiment in the last 25 years, aligns with the necessity to reduce the on-site nominal sheep stocking rates over the same period on this farmlet. This finding appears at odds with projected climate change driven modelling that forecast a largely positive outcome on pasture growth in summer moist environments. In this paper we explore the apparent discrepancies between the observed and predicted climate-driven NHA by using a climate-driven pasture growth module within a larger process-based model …

Length Of Multi-Year Precipitation And Primary Production Relationships Vary Regionally Across Grasslands In The Central U.S., A. R. Hudson, D. P.C. Peters

IGC Proceedings (1977-2023)

Grasslands in the central United States span large temperature and aridity gradients and regionally differ in their drivers of water availability. These differences likely determine how drought event periodicity and duration can influence grassland growth, and are important to consider as global warming changes energy and water distribution across these systems. Here, we explored frequency patterns in annual grassland plant growth (aboveground net primary productivity (ANPP)) and precipitation (PPT) relationships for over 20 years at six long-term research sites spatially distributed across the central grassland region. We identified the periods (>1 year) these relationships are strongest- and when they …

Impact Of Climate Change On Surgery: A Scoping Review To Define Existing Knowledge And Identify Gaps, Tina Bharani, Rebecca Achey, Harris Jamal, Alexis Cherry, Malcolm K. Robinson, Guy J. Maddern, Deirdre K. Tobias, Divyansh Agarwal

Department of Surgery Faculty Papers

With climate change accelerated at a worrisome rate, global warming also will have implications for surgery and surgical practice. The goal of this current study was to systematically survey the literature and better understand how climate change has affected surgical disease burden, surgical care delivery, and surgical outcomes. We performed a comprehensive scoping review, screening 3334 unique citations from three databases – 1766 from Embase, 1329 from Pubmed and 239 from Scopus – to identify studies that had associated climate change with surgery. After systematic searching, quality appraisal, and data extraction, we synthesized findings from qualitative and quantitative studies. Twenty-six …

Response Of Reproductive Phenology To Soil Water Content Of Stipa Breviflora Under Warming And Nitrogen Application, L. Bai, H. Y. Ren, G. D. Han

IGC Proceedings (1977-2023)

Plant phenology is considered as the most direct and sensitive characteristic indicators of plant response to regional climate change. Based on the observation data of phenology and soil water content of Stipa breviflora in an experimental platform of warming and nitrogen application in Inner Mongolia desert steppe from 2009 to 2019. The results showed that warming and nitrogen application significantly advanced the reproductive phenological period (P < 0.001), and the interaction of warming and nitrogen application promoted the advance of reproductive phenological period (P < 0.05).

Utahns' Perceptions Of Climate Change And Disaster Vulnerabilities, Mufti Nadimul Quamar Ahmed, Jennifer E. Givens, Peter D. Howe, Jessica D. Ulrich-Schad

Utah People and Environment Poll (UPEP)

Climate change increases the frequency and severity of extreme weather events, making people more vulnerable in a variety of ways^1-2. It is essential to determine if individuals believe they are susceptible to the effects of climate change in order to develop effective adaptation strategies.

Climate change has contributed to extreme weather occurrences in Utah in recent years. For instance, in the summer of 2022, there was a severe or extreme drought in all of Utah's counties³. Health effects of drought vary with intensity⁴ and can cause climate related deaths directly and indirectly, such as by …

Tree Planting As An Adaptive Management Tool For Climate Change In Morocco, Stephanie J. Robinson

USF Tampa Graduate Theses and Dissertations

The practice of planting fruit trees to combat climate change impacts in Morocco has been growing in popularity with support from the Moroccan government and non-profit organizations. Although it is often considered a successful adaptive management tool, tree planting initiatives (TPIs) in arid lands have not been thoroughly analyzed, their management is unstandardized, and these initiatives can cause harm when trees are planted in areas that cannot support them. To implement tree planting better these TPIs need to find areas where the trees they are introducing have the best chance of survival without negatively impacting the surrounding ecosystem and human …

Concerned But Confused: University Students' Knowledge And Perceptions Of Climate Change, And How They Plan To Address It In Their Future Personal And Professional Lives., Miranda Kistner, Jeremy Jiménez

The SUNY Journal of the Scholarship of Engagement: JoSE

This article explores university students’ knowledge and concern level towards climate change, as well as potential roles they see themselves playing as teachers in a world increasingly affected by its impacts. A survey of 135 university students was conducted at SUNY Cortland, a medium-size state university in Upstate New York. Results show that these university students (among them pre-service teachers) are highly concerned about the potential impacts of climate change, especially for future generations. While they demonstrate some accurate knowledge of climate change, many hold many misconceptions about its causes and consequences. In articulating how they can or do respond …

Vulnerability Of Elevation-Restricted Endemic Birds Of The Cordillera De Talamanca (Costa Rica And Panama) To Climate Change, Zhen Lui, Luis Sandoval, Lauren B. Sherman, Andrew M. Wilson

Environmental Studies Faculty Publications

Animals endemic to tropical mountains are known to be especially vulnerable to climate change. The Cordillera de Talamanca (Costa Rica and Panama) is a geographically isolated mountain chain and global biodiversity hotspot, home to more than 50 endemic bird species. We used eBird community science observations to predict the distributions of a suite of 48 of these endemic birds in 2006–2015, and in 2070, under four climate change scenarios. Species distributions were predicted using program Maxent, incorporating elevation, satellite derived habitat data, and WorldClim climate variables. Model fit, as assessed by Area under the Receiver Operator Curve (AUC), was very …

How Sensitive Are Catchment Runoff Estimates To On-Farm Storages Under Current And Future Climates?, David E. Robertson, Hongxing Zheng, Jorge L. Pena-Arancibia, Francis H S Chiew, Santosh Aryal, Martino E. Malerba, Nicholas J. Wright

Climate Science Research Articles

Storage of water in farm dams is important to support irrigation, stock requirements and domestic uses when reticulated water is unavailable. Farm dams that fill by intercepting landscape runoff change the total volume and seasonality of catchment streamflow, potentially impacting water policy outcomes. While numerous studies have quantified how climate change and farm dams independently change streamflow characteristics, few studies have investigated their interactions. This study investigates the interactions between farm dams and climate change in the Murray-Darling Basin of southern and eastern Australia. We use hydrological modelling that explicitly represent farm dams and remotely sensed data describing historical farm …

Reimagining Large River Management Using The Resist–Accept–Direct (Rad) Framework In The Upper Mississippi River, Nicole K. Ward, Abigail J. Lynch, Erik A. Beever, Joshua Booker, Kristen L. Bouska, Holly Embke, Jeffrey N. Houser, John F. Kocik, David J. Lawrence, Mary Grace Lemon, Doug Limpinsel, Madeline R. Magee, Bryan M. Maitland, Owen Mckenna, Andrew Meier, John M. Morton, Jeffrey D. Muehlbauer, Robert Newman, Devon C. Oliver, Heidi M. Rantala, Greg G. Sass, Aaron Shultz, Laura M. Thompson, Jennifer L. Wilkening

Biology Faculty Publications

Background Large-river decision-makers are charged with maintaining diverse ecosystem services through unprecedented social-ecological transformations as climate change and other global stressors intensify. The interconnected, dendritic habitats of rivers, which often demarcate jurisdictional boundaries, generate complex management challenges. Here, we explore how the Resist–Accept–Direct (RAD) framework may enhance large-river management by promoting coordinated and deliberate responses to social-ecological trajectories of change. The RAD framework identifies the full decision space of potential management approaches, wherein managers may resist change to maintain historical conditions, accept change toward different conditions, or direct change to a specified future with novel conditions. In the Upper Mississippi …

Effects Of Changing Climate Extremes And Vegetation Phenology On Wildlife Associated With Grasslands In The Southwestern United States, Tyler G. Creech, Matthew A. Williamson, Steven E. Sesnie, Esther S. Rubin, Daniel R. Cayan, Erica Fleishman

Human-Environment Systems Research Center Faculty Publications and Presentations

Assessments of the potential responses of animal species to climate change often rely on correlations between long-term average temperature or precipitation and species' occurrence or abundance. Such assessments do not account for the potential predictive capacity of either climate extremes and variability or the indirect effects of climate as mediated by plant phenology. By contrast, we projected responses of wildlife in desert grasslands of the southwestern United States to future climate means, extremes, and variability and changes in the timing and magnitude of primary productivity. We used historical climate data and remotely sensed phenology metrics to develop predictive models of …

“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 …

Alca: Comparing Icelandic Aluminum Emissions To The World Through Statistical Reasoning And Programming-Based Predictive Tools, Markus Sujansky

Iceland: Climate Change and The Arctic

Aluminum production is a process that is heavily reliant on large amounts of available

energy, and therefore lends itself to locations where energy production is abundant. Iceland, as a global leader in Geothermal and Hydropower energy, has experienced an industrial boom in the past 20-30 years, quickly becoming a top 10 worldwide aluminum producer. However, although the three main companies that operate their smelting processes in the country are powered by clean energy, they still import raw materials from all over the world, with source locations ranging from Brazil to Australia. In order to find out if the long distance …

Partnering For Climate Resilience: Exploring The Maturity Of Private-Sector Efforts In The Great Lakes Region, Lisa Greenwood, Yewande Abraham, Jennifer Schneider, Vicki Lin

Articles

Communities and businesses continue to experience the effects of climate change as global temperatures rise and extreme weather events become more frequent. In the United States (US), the public sector has traditionally been responsible for mitigating these risks; however, engaging the private sector is crucial, given industrial impacts on and vulnerability to climate change. Private-sector mitigation and adaptation efforts are critical in the Great Lakes Region due to aging infrastructure as well as its economic, environmental, and political importance in the US and Canada. This study explores private-sector resilience efforts in three Great Lakes cities to identify opportunities and trends …

Climate Change Impacts And Adaptation To Permafrost Change In High Mountain Asia: A Comprehensive Review, Prashant Baral, Simon Allen, Jakob F. Steiner, Tika R. Gurung, Graham Mcdowell

Department of Earth and Atmospheric Sciences: Faculty Publications

Changing climatic conditions in High Mountain Asia (HMA), especially regional warming and changing precipitation patterns, have led to notable effects on mountain permafrost. Comprehensive knowledge of mountain permafrost in HMA is mostly limited to the mountains of the Qinghai-Tibetan Plateau, with a strong cluster of research activity related to critical infrastructure providing a basis for related climate adaptation measures. Insights related to the extent and changing characteristics of permafrost in the Hindu Kush Himalaya (HKH), are much more limited. This study provides the first comprehensive review of peer-reviewed journal articles, focused on hydrological, ecological, and geomorphic impacts associated with thawing …

Combining Expert Opinions To Assess Risk Of Change In Earth Systems: Permafrost Collapse, Global Wildfire, And Water Security, Sayedeh Sara Sayedi

Theses and Dissertations

In a world of uncertainty and change, leaders should base their decisions on best available scientific evidence. However, history has shown that science is often inadequately incorporated into the decision-making process. This dissertation investigates three environmental issues to identify the challenges of considering Earth system dynamics in policymaking and management. I also propose solutions for improving the two-way exchange of knowledge and values between researchers and policymakers. In chapter one, I investigate subsea permafrost carbon sensitivity to climate change using an expert assessment. The analysis revealed that subsea permafrost contains significant carbon stocks and is already contributing to climate change …

Is Carbon Risk Priced In The Cross-Section Of Corporate Bond Returns?, Tinghua Duan, Frank Weikai Li, Quan Wen

Research Collection Lee Kong Chian School Of Business

This paper examines the pricing of a firm's carbon risk, measured by its carbon emissions intensity, in the cross-section of corporate bond returns. Contrary to the "carbon risk premium" hypothesis, we find bonds of firms with higher carbon emissions intensity earn significantly lower returns. This effect cannot be explained by a comprehensive list of bond characteristics and exposure to known risk factors. Investigating sources of the low carbon premium, we find the underperformance of bonds issued by carbon-intensive firms cannot be fully explained by divestment from institutional investors. Instead, our evidence is most consistent with investor underreaction to carbon risk, …

A Framework For Creating Virtual Reality Models For More Effective Coastal Flood Risk Communication, Tina Korani, Alexandrea Martinez

CSU Journal of Sustainability and Climate Change

Coastal cities are exposed to increasing risks of flooding from sea-level rise. Climate change is expected to double the frequency of coastal flooding within the next decade, and some areas could experience floods of a magnitude 100 times higher than currently (Vitousek et al., 2017). People living in at-risk areas often ignore the impact of climate change on flood intensity and frequency. Immersive visual storytelling techniques proved promising and powerful tools to engage with and raise awareness of flood hazards. Here, we are introducing a framework to use Virtual Reality (VR) to reach better people living in coastal cities and …
