Mitigating Emissions Associated With The Production Of Traded Goods, Dan André Quirapas, Brian Irvyn Chan, Albert E. Lamberte, Maria Zunally Rapada, Krista Danielle Yu Dec 2021

Mitigating Emissions Associated With The Production Of Traded Goods, Dan André Quirapas, Brian Irvyn Chan, Albert E. Lamberte, Maria Zunally Rapada, Krista Danielle Yu

Angelo King Institute for Economic and Business Studies (AKI)

The environmental impact of international trade is a concerning issue in the fight against climate change. Trade liberalization—combined with globally fragmented environmental policies—is often associated with the formation of pollution havens. This is because trade enables emissions leakages, which is defined as the outsourcing of emissions-intensive production to countries with weaker environmental regulations. Therefore, literature on this subject has suggested that a globally coordinated policy response is necessary to mitigate the impact of trade on climate change (Aichele & Felbermayr, 2012; Ben-David et al., 2020; Felbmermayr & Peterson, 2020). However, some studies have found that unilateral policy actions have no …


Breeding And Feeding Habitat Selection By An Island Endemic Bird May Increase Its Vulnerability To Climate Change, Paul M. Radley, Eddie J. B. Van Etten, David Blake, Robert A. Davis Nov 2021

Breeding And Feeding Habitat Selection By An Island Endemic Bird May Increase Its Vulnerability To Climate Change, Paul M. Radley, Eddie J. B. Van Etten, David Blake, Robert A. Davis

Research outputs 2014 to 2021

Characterizing patterns of habitat use is an important first step for effective conservation planning. Species restricted to low-lying islands are at greatest risk from climate change-related sea level rise, and requirements for breeding and foraging habitat may determine their risk from tidal inundation. The endangered Micronesian Scrubfowl (Megapodius laperouse senex) is a model species for understanding these impacts. This species faces the cumulative challenges of tourist visitation, invasive species, and rising sea levels, yet little is understood about its habitat use in the Rock Islands Southern Lagoon Conservation Area (RISL) of Palau. We studied the habitat requirements of this mound-nesting …

United States Geological Survey: Staff Publications

The Gulf of Maine, USA is home to four colonial co-nesting tern species: Least Tern (Sternula antillarum), Common Tern (Sterna hirundo), Arctic Tern (Sterna paradisaea), and the federally endangered Roseate Tern (Sterna dougallii). Over three decades of visual observations of chick provisioning were compiled for a comparative dietary study in the region, including the first detailed descriptions of Least and Roseate Tern chick diets. Three prey groups comprised the majority of chick diets among tern species between 1986–2017: hake (Urophycis spp. or Enchelyopus cimbrius) 28–37% frequency of occurrence (FO), sand lance …


Development Of Predictive Models For Water Budget Simulations Of Closed-Basin Lakes: Case Studies Of Lakes Azuei And Enriquillo On The Island Of Hispaniola, Mahrokh Moknatian, Michael Piasecki Oct 2021

Development Of Predictive Models For Water Budget Simulations Of Closed-Basin Lakes: Case Studies Of Lakes Azuei And Enriquillo On The Island Of Hispaniola, Mahrokh Moknatian, Michael Piasecki

Publications and Research

The historical water level fluctuations of the two neighboring Caribbean lakes of Azuei (LA) and Enriquillo (LE) on Hispaniola have shown random periods of synchronous and asynchronous behaviors, with both lakes exhibiting independent dynamics despite being exposed to the same climatic forces and being directly next to each other. This paper examines their systems' main drivers and constraints, which are used to develop numerical models for these two lakes. The water balance approach was employed to conceptually model the lakes on an interannual scale and examine the assumptions of surface and subsurface processes. These assumptions were made based on field …

USDA Wildlife Services: Staff Publications

Ammonia (NH3) is the most abundant alkaline component and can react with atmospheric acidic species to form aerosols that can lead to numerous environmental and health issues. Increasing atmospheric NH3 over agricultural regions in the US has been documented. However, spatiotemporal changes of NH3 concentrations over the entire US are still not thoroughly understood, and the factors that drive these changes remain unknown. Herein, we applied the Atmospheric Infrared Sounder (AIRS) monthly NH3 dataset to explore spatiotemporal changes in atmospheric NH3 and the empirical relationships with synthetic N fertilizer application, livestock manure production, and climate factors across the entire US …

Diminishing Opportunities For Sustainability Of Coastal Cities In The Anthropocene: A Review, John W. Day, Joel D. Gunn, Joseph Robert Burger

Biology Faculty Publications

The world is urbanizing most rapidly in tropical to sub-temperate areas and in coastal zones. Climate change along with other global change forcings will diminish the opportunities for sustainability of cities, especially in coastal areas in low-income countries. Climate forcings include global temperature and heatwave increases that are expanding the equatorial tropical belt, sea-level rise, an increase in the frequency of the most intense tropical cyclones, both increases and decreases in freshwater inputs to coastal zones, and increasingly severe extreme precipitation events, droughts, freshwater shortages, heat waves, and wildfires. Current climate impacts are already strongly influencing natural and human systems. …

Watershed Sciences Student Research

Effects of climate change-driven disturbance on lake ecosystems can be subtle; indirect effects include increased nutrient loading that could impact ecosystem function. We designed a low-level fertilization experiment to mimic persistent, climate change-driven disturbances (deeper thaw, greater weathering, or thermokarst failure) delivering nutrients to arctic lakes. We measured responses of pelagic trophic levels over 12 yr in a fertilized deep lake with fish and a shallow fishless lake, compared to paired reference lakes, and monitored recovery for 6 yr. Relative to prefertilization in the deep lake, we observed a maximum pelagic response in chl a (+201%), dissolved oxygen (DO, −43%), …


Pervasive Changes In Stream Intermittency Across The United States, Kendra E. Kaiser Aug 2021

Pervasive Changes In Stream Intermittency Across The United States, Kendra E. Kaiser

Geosciences Faculty Publications and Presentations

Non-perennial streams are widespread, critical to ecosystems and society, and the subject of ongoing policy debate. Prior large-scale research on stream intermittency has been based on long-term averages, generally using annually aggregated data to characterize a highly variable process. As a result, it is not well understood if, how, or why the hydrology of non-perennial streams is changing. Here, we investigate trends and drivers of three intermittency signatures that describe the duration, timing, and dry-down period of stream intermittency across the continental United States (CONUS). Half of gages exhibited a significant trend through time in at least one of the …

Quo Vadis Lakes Azuei And Enriquillo: A Future Outlook For Two Of The Caribbean Basin's Largest Lakes, Mahrokh Moknatian, Michael Piasecki

Publications and Research

Lakes Azuei (LA) and Enriquillo (LE) on Hispaniola Island started expanding in 2005 and continued to do so until 2016. After inundating large swaths of arable land, submerging a small community, and threatening to swallow a significant trade route between the Dominican Republic and Haiti; worries persisted at how far this seemingly unstoppable expansion would go. The paper outlines the approach to a look forward to answer this question vis-à-vis climate change scenarios developed by the Intergovernmental Panel on Climate Change (IPCC). It uses numerical representations of the two lakes, and it examines how the lakes might evolve, deploying three …

Functionalized Ionic Liquids For Improved Co2 Hydrogenation Catalysts, Amol Nanduji Jaybhaye

Masters Theses & Specialist Projects

Climate change is one of the biggest problems we are facing today, and anthropogenic greenhouse gases contribute significantly to it. Among greenhouse gasses, carbon dioxide emission is increased drastically and affecting majorly for increasing global temperature, and anything we can do to mitigate carbon dioxide emission will be helpful. A carbon dioxide hydrogenation reaction is a promising technique that can convert carbon dioxide into value-added chemicals, but the reaction rate is slow, and for that, we can use catalysts that will accelerate the reaction rate. Platinum-based nanoparticles have sparked research related to energy and environmental catalysts. Catalytic properties are depending …

Research Collection School of Social Sciences

Climate change is one of the biggest challenges facing many countries in the Asia Pacific. Asia as a whole is a primary contributor to carbon emissions. According to the BP Statistical Review of World Energy 2020, the Asia Pacific region alone accounts for more than half of the world’s total greenhouse gas emissions. This represents an increase in consumption of oil, gas, and coal in Asia Pacific from 44.5% in 2009 to 50.5% in 2019. According to the review, compared to the rest of the world, Asia Pacific had the highest growth rate (2.7%) of carbon emissions between 2008 and …

There is a strong scientific consensus that anthropogenic climate change is happening and that its impacts can put both ecological and human systems in jeopardy. Social psychology, the scientific study of human behaviours in their social and cultural settings, is an important tool for understanding how humans interpret and respond to climate change. In this article, we offered a systematic review of the social psychological literature of climate change. We sampled 130 studies on climate change or global warming from 80 articles published in journals indexed under the “Psychology, social” category of Journal Citation Reports. Based on this sample, …

Glacier mass variations are climate indicators. Therefore, it is essential to examine both winter and summer mass balance variability over a long period of time to address climate-related ice mass fluctuations. In this study, we analyze glacier mass balance components and hypsometric characteristics with respect to their interactions with local meteorological variables and remote large-scale atmospheric and oceanic patterns. The results show that all selected glaciers have lost their equilibrium condition in recent decades, with persistent negative annual mass balance trends and decreasing accumulation area ratios (AARs), accompanied by increasing air temperatures of +0.45 C decade 1. The controlling factor …

Michigan Tech Publications

Among its many impacts, climate warming is leading to increasing winter air temperatures, decreasing ice cover extent, and changing winter precipitation patterns over the Laurentian Great Lakes and their watershed. Understanding and predicting the consequences of these changes is impeded by a shortage of winter-period studies on most aspects of Great Lake limnology. In this review, we summarize what is known about the Great Lakes during their 3–6 months of winter and identify key open questions about the physics, chemistry, and biology of the Laurentian Great Lakes and other large, seasonally frozen lakes. Existing studies show that winter conditions have …

Just about every indicator of drought is flashing red across the western U.S. after a dry winter and warm early spring. The snowpack is at less than half of normal in much of the region. Reservoirs are being drawn down, river levels are dropping and soils are drying out.

It’s only May, and states are already considering water use restrictions to make the supply last longer. California’s governor declared a drought emergency in 41 of 58 counties. In Utah, irrigation water providers are increasing fines for overuse. Some Idaho ranchers are talking about selling off livestock because rivers and reservoirs …

Intangible Cultural Heritage: A Benefit To Climate-Displaced And Host Communities, Gül Aktürk, Martha B. Lerski

Publications and Research

Climate change is borderless, and its impacts are not shared equally by all communities. It causes an imbalance between people by creating a more desirable living environment for some societies while erasing settlements and shelters of some others. Due to floods, sea level rise, destructive storms, drought, and slow-onset factors such as salinization of water and soil, people lose their lands, homes, and natural resources. Catastrophic events force people to move voluntarily or involuntarily. The relocation of communities is a debatable climate adaptation measure which requires utmost care with human rights, ethics, and psychological well-being of individuals upon the issues …

Vignette 12: The Blob, Nicholas Bond

Institute Publications

A marine heat wave of unprecedented severity, areal extent and duration occurred in the Northeast Pacific Ocean during 2014-2016. This event, known as the “Blob,” had a wide variety of far- ranging effects on physical, chemical, and biological ocean properties. Because the Blob was such a massive perturbation, it represents an attractively large signal for inquiry in the Salish Sea. It represents a dress rehearsal for typical conditions in future decades due to global climate change.

Vignette 20: Fraser River Estuary In Need Of Urgent Intensive Care, Laura Kehoe, Tara G. Martin

Institute Publications

The Fraser River is the lifeline of the Salish Sea, influencing its stratification, circulation, and primary productivity. If we do not take strong action to conserve the Fraser River estuary, two-thirds of the species at risk in this region are predicted to have a less than 50% chance of survival. Many of the region's most iconic species could disappear. Conservation action combined with environmental governance is a pathway for a brighter future for the Fraser River and other highly contested regions.

As one of the first tribes in western Washington to complete a climate adaptation plan and vulnerability assessment, the Jamestown S’Klallam Tribe has identified and prioritized areas where changing climate conditions will leave tribal resources, infrastructure, economy and health most vulnerable, Climate …


Effects Of The Transportation And Climate Initiative On The Maine Economy: An Analysis Of Cap-And-Invest And Its Heterogeneous Impacts On Rural And Urban Households, William L. Somes May 2021

Effects Of The Transportation And Climate Initiative On The Maine Economy: An Analysis Of Cap-And-Invest And Its Heterogeneous Impacts On Rural And Urban Households, William L. Somes

Honors College

In December 2020, a memorandum of understanding (MOU) was released by the Transportation and Climate Initiative Program (TCI-P), a collaboration of 13 jurisdictions in the New England and Mid-Atlantic regions of the United States. Modeled on the Regional Greenhouse Gas Initiative (RGGI), the TCI-P follows a cap-and-invest framework to reduce emissions from the transportation sector by 26% from 2022 to 2032. Since the TCI-P is expected to raise the price of gasoline by 5¢ to 9¢ per gallon, there has been concern that some populations may be disproportionately affected. The present research studies the potential heterogeneous impacts of the TCI-P …


Predicting Range Shifts For The Virginia Opossum In Maine, Sara Griffin May 2021

Predicting Range Shifts For The Virginia Opossum In Maine, Sara Griffin

Honors College

Species distribution and movement are increasingly influenced by climate change and human expansion. The Virginia opossum (Didelphis virginiana) has been observed expanding their range northward due to the warming temperatures and urbanization. The Virginia opossums’ northern range is thought to be restricted by two abiotic winter factors, snow cover and low temperatures, which prevents foraging and ultimately leads to starvation. For this study, I predicted the movement of the Virginia opossum northward into central Maine and beyond based on current climate change trends. Microclimate temperatures were recorded using data-loggers and climate variable datasets were used to determine if …

Indigenous peoples of the Northern Pacific Rim have harvested salmon for more than 10,000 years, and Pacific salmon (Oncorhynchus spp.) form the foundation of social-ecological systems encompassing communities from California to Kamchatka and Northern Japan. Through continuous placed-based interdependence with salmon, Indigenous societies formed deliberate and well-honed systems of salmon management. These systems promoted the sustained productivity of salmon fisheries. In Canada and the United States, Indigenous sovereignty and resource stewardship were forcibly disrupted by colonial government authority. Despite the destructive impacts of colonization, Indigenous culture and knowledge are resurgent in Canada and the United States. Indigenous fishing technologies and …

Vignette 21: How Ecological Time-Series Inform Response To Stressors, Jackson W.F. Chu

Institute Publications

An important part of biodiversity monitoring includes assessing the differences in vulnerability across parts of an ecosystem. Hypoxia is one of the big three climate- related stressors causing biodiversity loss in the oceans. As the ocean warms, its capacity to hold oxygen becomes reduced. At the same time, concurrent shifts in circulation result in changes to how oxygen gets transported from the surface (where oxygen dissolves into the ocean) to the seafloor and from offshore to inshore areas. When a habitat experiences a substantial drop in oxygen, below the point needed to sustain everyday life, animals respond by migrating away, …

Vignette 17: Salish Sea Jellyfish, Correigh Greene

Institute Publications

The Salish Sea is home to a diverse community of gelatinous zooplankton (or "jellies"). In their adult forms, jellies comprise a relatively large proportion of biomass in the Salish Sea. Questions regarding jellyfish abundance and climate variation in the Salish Sea have been difficult to address, in part because of a lack of consistent monitoring. Research presented in this vignette suggests that jellyfish are sensitive to climate signals like marine water temperatures, but do not appear to be systematically increasing in abundance over time. Due to advances in modeling, we may gain a better perspective on the roles jellies play …

Vignette 04: Olympia Oysters, Jodie Toft, Betsy Peabody

Institute Publications

Olympia oysters (Ostrea lurida) are our only native oyster species here in the Salish Sea. Olympia oysters once covered an estimated 13-26% of the intertidal area in Puget Sound, mostly near the heads of inlets. A combination of overharvest, pollution, and habitat loss reduced the current population to less than 4% of historic numbers, though sparse numbers of Olympia oysters can still be found throughout most of their historic distribution. Looking to the future, as our region’s marine waters experience effects of climate change and ocean acidification (OA), native species such as the Olympia oyster may prove to …
