Urban Heat Dynamics In Pune: The Influence Of Land Cover And Local Climate, Arpit Tiwari, Preethi Nanjundan, Ravi Ranjan Kumar, Ananya Karmakar, Satyaban Bishoyi Ratna

Northeast Journal of Complex Systems (NEJCS)

Urban areas with high population density and extensive infrastructure development have been experiencing an increasing strain on the local heat budget, leading to a surge in heat-related illnesses and discomfort. This study examined the impact of climate and land use as heat islands in Pune, India, from 2012 to 2023 at six different locations representing varying degree of urbanization. Satellite land cover observations revealed that 55.17% of the total area was urbanized in the city itself, which was limited to 44.8% in 2012. This urbanization has significantly impacted the increasing tendency of maximum temperature (T_max; 0.13℃ to 1.63℃ …

Managing Beyond Water: Utilizing Community Well-Being Interviews In The Upper Yakima River Basin, Usa, For Climate Change Adaptation, Rebecca Gustine, Alexander Theophilus, Courtney G. Flint, Jessica D. Ulrich-Schad, Emma Epperson, Claudia Mendez Wright, Jennifer C. Adam

Sociology, Social Work and Anthropology Student Research

In contemporary, natural resources dependent and specialized communities, community well-being is connected to the environment. Understanding the local connections between community well-being and the environment can provide a more complete understanding of how to manage social-ecological systems and promote community resilience. Herein, we combine semi-structured community well-being interviews with hydrologic modeling using the variable infiltration capacity (VIC) model to suggest climate adaptation pathways for a diverse set of community interests. We found that community well-being across the Yakima River Basin was connected to water, snow, and the environment through recreation opportunities, aesthetics, livelihoods, and having clean water and air. Additionally, …

Mind The Green Skills Gap, Panchali Guha

Asian Management Insights

The need to build tomorrow’s sustainable green economy today. Climate change and the shift towards a net zero economy pose significant risks to jobs globally unless workers are equipped with green skills and competencies. There is already a green skills gap in the labour market that will only widen over time if it is not addressed. Comprehensive and coordinated policies must be developed to define and measure green jobs and skills, enhance educational offerings, and provide support for workers and employers during the transition.

Impacts Of Ocean Acidification On The Palatability Of Two Antarctic Macroalgae And The Consumption Of A Grazer, Hannah E. Oswalt, Margaret O. Amsler, Charles D. Amsler, James B. Mcclintock, Julie B. Schram

Faculty, Staff, and Students

Increases in atmospheric CO2 have led to more CO2 entering the world’s oceans, decreasing the pH in a process called ’ocean acidification’. Low pH has been linked to impacts on macroalgal growth and stress, which can alter palatability to herbivores. Two common and ecologically important macroalgal species from the western Antarctic Peninsula, the unpalatable Desmarestia menziesii and the palatable Palmaria decipiens, were maintained under three pH treatments: ambient (pH 8.1), near future (7.7) and distant future (7.3) for 52 days and 18 days, respectively. Discs of P. decipiens or artificial foods containing extracts of D. menziesii from each treatment were …

What Do Utahns Think About Global Warming And Climate Change?, Scott Hotaling, Kendall Becker, Lendel K. Narine, Jessica Ulrich-Schad, Roslynn Mccann, Peter D. Howe

All Current Publications

In Utah, there is widespread consensus that global warming is happening, and the strength of this consensus has been steadily rising since 2010. Over the last 14 years, some public opinion metrics have risen dramatically while others have been largely stable. The degree of climate impacts in Utah will depend on residents’ perceptions of climate change and support for implementing policies to help the state adapt to warmer temperatures, more extreme weather events, and other associated changes. In this fact sheet, we integrate multiple data sources to summarize the status and trends of Utahns’ opinions on climate change.

Operationalizing And Measuring Climate Change Adaptation Success, Henry A. Bartelet, Michele L. Barnes, Lalu A.A. Bakti, Graeme S. Cumming

Quantitative Methods and Information Technology Faculty Publications

In a context of rapid global change, understanding whether and how adaptation to climate change can be considered successful has become an important research gap within the climate change adaptation literature. Although definitions of adaptation success have been formulated, it remains unclear how they can be operationalized and tested empirically. To address this gap, we operationalized one of the most prominent definitions of successful adaptation within the academic literature, which describes success as adaptations that support reductions in risk and vulnerability without compromising sustainability. Specifically, drawing on data collected from 209 coral reef tourism operators across 28 locations and eight …

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 article examines the pricing of a firm’s carbon risk in the corporate bond market. Contrary to the “carbon risk premium” hypothesis, bonds of more carbon-intensive firms 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 alpha, 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 the predictability of carbon intensity for firm cash-flow news, creditworthiness, and environmental incidents.

SOSE Affiliate: Manila Observatory

This paper analyzed the various mobility patterns related to climate change in urban areas, focusing on the impacts of tidal floods and land subsidence in the coastal area of Central Java. The gradual changes in the coastal area are driven by climate change and development plans around the village, which have increased vulnerability. The community often experiences the impacts of rising sea levels and land surface subsidence, damaging the residential environment, public facilities, and hindering transportation and economic activities. This paper explores the experiences of different mobility types, including displacement, voluntary mobility, and immobility. A mixed-method approach was used, involving …

The State Of Global And African Ecology, Peter Knox

Landas

This article recounts the growth of concern for the environment in the latter half of the 20th Century, and its entry into Catholic magisterial theology. It expands on the ecological theory of planetary boundaries, and identifies how the theory surfaces in Pope Francis’ 2015 encyclical Laudato Si’. Based upon solid contemporary science, the encyclical is well founded to outline an appropriate and compassionate moral theology of care for creation. The article cites multiple instances where African people are at the nexus of environmental and social crises, focusing on how contemporary ecological factors affect women in particular. Environmental crises should not …

Cloud Microphysical Response To Entrainment Of Dry Air Containing Aerosols, Jae Min Yeom, Hamed F. Sadi, Jesse Anderson, Fan Yang, Will Cantrell, Raymond Shaw

Michigan Tech Publications

Impacts of aerosol particles on clouds, precipitation, and climate remain one of the significant uncertainties in climate change. Aerosol particles entrained at cloud top and edge can affect cloud microphysical and macrophysical properties, but the process is still poorly understood. Here we investigate the cloud microphysical responses to the entrainment of aerosol-laden air in the Pi convection-cloud chamber. Results show that cloud droplet number concentration increases and mean radius of droplets decreases, which leads to narrower droplet size distribution and smaller relative dispersion. These behaviors are generally consistent with the scenario expected from the first aerosol-cloud indirect effect for a …

Current Food Trade Helps Mitigate Future Climate Change Impacts In Lower-Income Nations, Kushank Bajaj, Zia Mehrabi, Thomas O. Kastner, Jonas Jägermeyr, Christoph Müller, Florian , Schwarzmüller, Thomas Hertel, Navin Ramankutty

Department of Agricultural Economics Faculty Publications

The risk of national food supply disruptions is linked to both domestic production and food imports. But assessments of climate change risks for food systems typically focus on the impacts on domestic production, ignoring climate impacts in supplying regions. Here, we use global crop modeling data in combination with current trade flows to evaluate potential climate change impacts on national food supply, comparing impacts on domestic production alone (domestic production impacts) to impacts considering how climate change impacts production in all source regions (consumption impact). Under 2°C additional global mean warming over present day, our analysis highlights that climate impacts …

Corporate Scenarios: Drawing Lessons From History, Madison Condon

Seattle University Law Review

As corporations are increasingly pressed to reveal information about their exposure to climate-related risks, they are often asked to undertake and disclose the outcome of “scenario analysis.” In this exercise, corporations, including financial institutions, examine how their business would fare under different pathways the future may take. One oft-used scenario, for example, is the International Energy Agency’s “Net-Zero by 2050: A Roadmap for the Energy Sector.” This Essay presents a history of the use of scenarios as a corporate planning tool, particularly in the oil industry, arguing that it is key for understanding our present moment and the role of …

Modeling The Impacts Of The Current And Projected Temperatures On Spongy Moth Population Dynamics, Adrienne B. Spring

Theses and Dissertations

The spongy moth (Lymantria dispar) is an invasive forest pest that has caused significant ecological damage across the United States. Its invasion front is shaped by a number of factors, including temperature in both the northern and southern regions. With ongoing climate change, areas that were previously uninhabitable may become increasingly favorable for moth population establishment and expansion, while other areas may experience thermal stress limiting persistence. This study develops a temperature-driven population model to analyze how temperature affects the spongy moth population dynamics along the invasion front. This model incorporates temperature effects on fecundity, stage-specific survival rates, …

Adaptation For Whom? Understanding The Impacts Of Dyke Policies On Small-Scale Farmers In Ca Mau Province Of Vietnam, Nguyen Minh Quang, Nguyen Van Minh, Nguyen Vo Chau Ngan, Martha B. Lerski

Publications and Research

Low-lying deltas worldwide are extremely vulnerable to sea-level rise. As the risks of climate-induced flooding become increasingly clear, the thirst for infrastructure-driven adaptation increases. This highlights a patent need to understand the impacts of engineering adaptation solutions, especially those targeting built structures such as dykes and sluices, on farmers from a bottom-up, farmer-centred perspective. The study addresses this call by examining cases where dyke policies, while successful in some dimensions, have undermined small-scale farmer livelihoods in Ca Mau ― Vietnam’s southernmost rural province. It identifies areas in need of attention and adds empirical data related to this group of farmers. …

Hope For Louisiana’S Coast: From Catastrophic Loss To Transient Gain, Richard Condrey, Brian D. Marx, Frank Saforo, Rudy Bartels

Faculty Publications

Louisiana’s fifty-billion-dollar coastal restoration plan relies on selected interpretations of a small dataset of coastwide land measurements. In the 1990’s, the plan’s founders used a mathematically impossible interpretation of an improbable manipulation of the initial (1932-1990) dataset to justify their misconceptions regarding natural conditions; delta-switching; and a failing, 60-year restoration goal. In 2017, the dataset was updated to 2016 and used to suggest that land loss had slowed to -28 km2/yr (-1 football field/100 min) since 2010. We find that the dataset does not support this suggestion. Rather, we find the dataset supports our hypothesis that increasing precipitation in the …

Exploring Coupled Land Use -- Climate Change Impacts In The Northeast United States From 2020-2025 With Implications For Bombus Habitat Suitability, Archana Prasad

Theses, Dissertations and Culminating Projects

The combined impacts of land use and climate change pose significant challenges to bumblebee populations in the Northeast United States (NEUS), a region characterized by dense urbanization, diverse landscapes, and exposure to climate extremes. As urban and suburban areas expand, the loss of agricultural lands and open spaces alters habitat availability for bumblebees, which rely on grasslands, meadows, and forest edges for nesting and foraging. Simultaneously, the NEUS is experiencing an increase in extreme climate events, including prolonged heatwaves, heavy precipitation, and shifts in temperature patterns. Using CMIP6 climate model projections, we analyzed trends in nine climate indices. Our results …

Cellular Responses Of Astrangia Poculata (Ellis And Solander, 1786) And Its Symbiont To Experimental Heat Stress, Tyler E. Harman, Daniel Barshis, Briana Hauff Salas, Kevin B. Strychar

Biological Sciences Faculty Publications

Climate change has had devastating effects on tropical coral reefs; however, much less is known regarding how heat stress affects temperate coral. This research focuses on Astrangia poculata (Ellis and Solander, 1786) collected from Narragansett Bay, RI, during the summer and winter seasons and understanding the effect of experimental thermal extremes (i.e., 26 °C) on seasonally different populations. Photosynthetic efficiency (Fv/Fm), symbiont density (via an inverse relationship with pixel intensity), and oxidative stress via reactive oxygen species (ROS) concentrations were measured on symbiotic and aposymbiotic A. poculata. Higher Fv/Fm rates were observed in summer- vs. winter-collected corals (p ≤ …

Co₂ Isotopologues From The Ace Satellite, D. English, P. Bernath, C. Boone

Chemistry & Biochemistry Faculty Publications

Carbon dioxide isotopologues have been studied thoroughly in the troposphere. In the stratosphere, the minor oxygen CO₂ isotopologues have anomalous abundances due to their exchange reactions with isotopically fractionated ozone, differentiating them from tropospheric CO₂. Previously a model predicted that this anomalous isotopic abundance continues into the mesosphere but lacked verification from experimental observations. Here we use the Atmospheric Chemistry Experiment Fourier Transform Spectrometer which records infrared transmittance spectra of the Earth's limb from low Earth orbit using solar occultation. These infrared spectra provide measurements of global CO₂ isotopologue volume mixing ratios (VMRs) from the upper troposphere to the lower …

The Strategic And Governance Implications Of Solar Radiation Modification: Perspectives From Delegates Of International Climate Negotiations, Todd L. Cherry, Steffen Kallbekken, David M. Mcevoy, Wai Yan Siu

ODU Articles

The lack of progress in addressing climate change has led to increased interest in solar radiation modification (SRM)—a collection of large-scale interventions that cool the planet by managing the amount of solar radiation that reaches the earth. SRM complicates climate change governance because, in addition to advancing collective action to reduce greenhouse gas emissions, governance needs to restrain unilateral SRM action while balancing diverging actor interests, ethical risks and scientific uncertainty. We survey international climate policy experts for their assessments of the potential for effective global governance of SRM and the likelihood of possible international responses to unilateral SRM scenarios. …

Multi-Scale Analysis Of Karst Aquifer Vulnerability To Climate Change And Contamination Processes, Shishir Sarker

Theses and Dissertations--Earth and Environmental Sciences

Karst aquifers represent some of the world’s most productive yet vulnerable groundwater systems, supplying freshwater to approximately 10% of the global population across 15% of Earth’s ice-free land surface. Their distinctive hydrological characteristics— including rapid recharge, preferential flow paths, and limited natural filtration— create unique vulnerabilities to both climate variability and contamination that pose significant challenges for sustainable water resource management. This dissertation presents a comprehensive multi-scale analysis of karst aquifer vulnerability through three interconnected studies that examine climate change impacts, microbial contamination dynamics, and contaminant transport processes across diverse geographic and hydrogeologic settings.

Low Salinities Impair Heat Tolerance And Alter Reproductive Traits With No Implications For Survival In A Marine Annelid From Coastal Habitats, Gabrielle Newton, Gloria Massamba-N'Siala

Biological Sciences Faculty Publications

Climate change is expected to intensify salinity and temperature fluctuations in estuarine and coastal habitats. However, the impact of salinity variation on ectotherms’ thermal tolerance remains underexplored, limiting our understanding of the interplay between these stressors. This study investigated salinity-dependent changes in life history traits (survival, growth rate, fecundity, and egg size) over a 33-day exposure to a salinity gradient (12, 17, 22, 27, 32, 35, 40, 45, 50) in the marine annelid Ophryotrocha labronica. Individuals that survived the salinity treatments were assessed for their upper and lower thermal tolerance limits. Female individuals, the target of the study, exhibited …
