▼ Species are expected to respond to
global warming through range shifts that are either poleward or towards higher altitude such that they track the movement of their current thermal niches. This generalized view is fundamentally flawed because it marginalizes the role of key biological aspects in shaping ecosystems. For example, it disregards any potential influence that phenotypic flexibility may convey, the influence of habitat heterogeneity and the availability of microclimates as thermal refugia, differences between species dispersal ability, the importance of species interactions, and the influence of phenological mismatches. Given the limitations associated with the view that species will deal with
global warming by continually migrating, as well as the rapid rate of
warming, there is an urgent need to improve the understanding of how species potentially may respond. Thus, it is crucial that mechanistic approaches are adopted to generate a holistic perspective of the factors that govern species distributions and use this information to forecast responses to
global warming.
Physiological studies are vital because knowing the physiological tolerances of a species provides insight into their fundamental niche, and also provides a means of identifying species that face higher risks of experiencing more immediate effects due to
global warming. Autecological knowledge would also serve to refine the species fundamental niche to more closely resemble their realized niche. In this regard, this thesis identifies arboreal mammals in the tropics as being vulnerable to hyperthermia due to
global warming. The basis of this claim is related to the exposed lifestyle of many arboreal species, the biphasic effect of temperature on biological processes and the hypothesis that natural selection would have favoured the optimisation of bodily functions at or close to the species-specific body temperatures (Tb).
Initially, there is a positive relationship between biological process and temperature as the rate of processes increase with temperature, up to a maximum point. Thereafter, hyperthermia ensues as further increases in temperature results in a rapid decline in the rate of said processes. Thus, it is plausible to expect that species with lower Tb risk deleterious effects at lower absolute Tbs relative to their higher Tb counterparts. Therefore, it is concerning that many small, tropical endotherms have low and thermolabile Tbs that, because of the small temperature differential between themselves and the ambient (Ta), compromises their capacity to passively off-load excess stored body heat. In addition, the high humidity of tropical environments would theoretically reduce their capacity to retard heat storage by off-loading body heat via evaporation. This reduced capacity to dissipate excess stored body heat, in combination with the exposed life-style of an arboreal species, suggests that small, tropical arboreal mammals are vulnerable to hyperthermia should even minor increases in Ta occur.
The aim of this thesis was to…

▼ The 21𝑠𝑡 century warming and acidification of tropical oceans will impact the structure
and function of coral reef ecosystems. Consequently, conservation efforts are increasingly
focused on identifying and protecting reef communities that demonstrate resilience to these
changes. In this thesis, I develop a scientific framework for identifying climate change
resilience in coral communities and, using Palau’s coral reefs as a case study, demonstrate
the application of this approach. First, I use coral skeletal records to evaluate the sensitivity
of coral communities to episodes of severe thermal stress. This information reveals coral reef
communities that consistently exhibit weak responses to multiple high temperature events.
Second, I evaluate coral reef community structure across a strong, natural pH gradient using
metrics informed by laboratory ocean acidification studies. The coral communities of Palau’s
Rock Island reefs show a level of pH tolerance that is unique amongst reefs studied to date.
Third, I conduct laboratory and field experiments to constrain the pH thresholds of these
resilient corals and investigate potential mechanisms for pH tolerance. Finally, I combine
archipelago-wide coral temperature and pH sensitivity data to construct climate change
resilience indices. My study succeeds in identifying a small number of coral communities
that have the potential to withstand 21𝑠𝑡 century climate change and highlights the spatial
variability in community responses to ocean warming and acidification. Critically, I present
a set of scientific tools and approaches for identifying resilient coral reef communities that
has applicability to coral reefs worldwide.

▼ Since the Last Glacial Maximum (LGM, ~ 20,000 years ago) air temperatures warmed,
sea level rose roughly 130 meters, and atmospheric concentrations of carbon dioxide increased.
This thesis combines global models and paleoceanographic observations to constrain
the ocean’s role in storing and transporting heat, salt, and other tracers during this
time, with implications for understanding how the modern ocean works and how it might
change in the future.
• By combining a kinematic ocean model with “upstream” and “downstream” deglacial
oxygen isotope time series from benthic and planktonic foraminifera, I show that the
data are in agreement with the modern circulation, quantify their power to infer circulation
changes, and propose new data locations.
• An ocean general circulation model (the MITgcm) constrained to fit LGM sea surface
temperature proxy observations reveals colder ocean temperatures, greater sea ice extent,
and changes in ocean mixed layer depth, and suggests that some features in the
data are not robust.
• A sensitivity analysis in the MITgcm demonstrates that changes in winds or in ocean
turbulent transport can explain the hypothesis that the boundary between deep Atlantic
waters originating from Northern and Southern Hemispheres was shallower at
the LGM than it is today.

Mechanisms of Tropical Pacific Climate Change: Beyond the Bjerknes Feedback.

(more)
▼ Mechanisms of tropical Pacific climate variability and change are studied in numerical experiments of future anthropogenic
global warming (AGW), the Last Glacial Maximum (LGM) 21,000 years ago, and decadal variability (PDV). According to these mechanisms the equatorial Pacific does not become either El Niño- or La Niña-like as the tropics warm up in response to increasing greenhouse gases. Because humidity increases much faster than precipitation as the tropical atmosphere warms up, theory and models anticipate a slowing-down of the Walker circulation in order to keep a balanced flow of water vapor into areas of convection. On long time scales characteristic of climate change, ocean dynamics oppose these changes in the Walker circulation. First, equatorial adjustment theory indicates that changes in the Walker circulation are not amplified via the Bjerknes feedback, as during El Niño or La Niña events. Second, during AGW, the ocean becomes more thermally stratified resulting in enhanced cooling of the equatorial cold tongue opposing the
warming there. These ideas can be applied to interpret proxies of the LGM for which El Niño and La Niña analogies have been made. However, the LGM tropics are not an opposite analogue to future AGW because the Walker circulation is also sensitive to changes in the geography of the Maritime continent associated with lower sea level. Models simulate a stronger Walker circulation when the tropics cool in order to compensate for the decrease in moisture due to a cooler/drier atmosphere. However, this response is opposed by a weakening of the ascending branch of the Walker circulation because convection is suppressed over vast areas of the Maritime Continent exposed due to lower sea level. In general, the patterns of
warming or cooling for AGW and LGM are not El Niño- or La Niña-like because of the opposing mechanisms presented here. As such, adherence to an ENSO analogy for interpreting tropical Pacific climate change can lead to serious misconceptions. However, proxies of the thermocline tilt can provide unequivocal evidence of changes in the Walker circulation because the pressure gradient associated with the thermocline tilt has to be in balance with the trade winds at all timescales.

▼ This dissertation explores two aspects of interdecadal climate variability: the predictability of variability in the tropical Pacific region on longer-than-interannual timescales, and changes to subsurface heat content in the tropical Atlantic Ocean over a decade. Chapter 1 assesses the ability of a general circulation model (GCM) and an intermediate- complexity model (ICM) to simulate persistent cool states of the Tropical Pacific. These states, which are La Niña-like on average, last from seven to ten years and induce prolonged droughts in many parts of the world. We find that these models produce analogs to real-world examples of these states and that they are modestly predictable in the ICM. We also find some predictability of the interdecadal shifts in the mean state in this model. In Chapter 2, an attractor reconstruction technique is used to investigate the predictability of interdecadal variability in the ICM further. We find that the interdecadal regimes of the ICM emerge as a pair of distinct orbits in a three-dimensional state space, and that the observed system possesses some comparable characteristics. The ICM is found to spend over a third of the time in states from which the regime of the following fifteen years is predictable with high confidence. The implications for developing an interdecadal prediction scheme are discussed. Chapter 3 examines changes in the heat content of the tropical Atlantic below the thermocline during the recent global warming hiatus. We use simulated Lagrangian particles in an ocean reanalysis dataset to analyze the changes to the circulation of the upper tropical Atlantic Ocean that occurred between the hiatus decade and the decade prior to it; and develop a testable hypothesis for how variability in the tropical Pacific region may have influenced the subsurface heat content of the Atlantic.

The release of carbon dioxide (CO2) emissions into the atmosphere is a leading contributor to global warming. Carbon capture and sequestration (CCS) strives to mitigate the effects of CO2 on the atmosphere, traditionally by expensive and energy-intensive chemisorptive approaches. CO2 capture by physisorbents such as hybrid ultramicroporous materials (HUMs) is a step toward cheaper and more efficient CCS. In this study, the effect of pyrazine ring orientation upon CO2 adsorption is investigated for TIFSIX-3-Ni, a leading HUM for CO2 selectivity. Rigid systems are constructed by eliminating disorder from the unit cell as determined by in situ characterization. Density Functional Theory (DFT) and Grand Canonical Monte Carlo (GCMC) methods are used to investigate the effect of tilting and ordering pyrazine rings upon CO2 loading and isosteric heat of adsorption (Qst). Results show that more edge to face interactions between pyrazine CH moieties and the CO2 molecule induce a preferred binding site. Systems with chemically distinct binding sites exhibit a Qst trend comparable to that which is experimentally observed, showing first preference for binding in smaller pores using models treated with both UFF and OPLS-AA Lennard-Jones parameters. It is also noted that the degree of pyrazine ring tilting affects the energetics of the sorbent-sorbate interactions, meriting further study. This work highlights the importance of subtle structural dynamics in adsorption performance of leading porous materials, and can be used to guide further fine-tuning of physisorbent materials for gas sorption applications.

▼ The study of
global warming and its effects is becoming increasingly popular due to steady increase in the environmental pollution. Local
warming of a particular place which in turn contributes to the
global warming can be studied through temperature variations of the local water bodies due to changes in the environment. In the present work, using the weather data obtained for New Brunswick, a general trend for variation in ambient temperature during the year is determined by fitting suitable curves using curve-fitting technique. Using this, the transient temperature distribution in the lake is determined numerically. The effect of many driving parameters such as ambient temperature, relative humidity, wind speed, solar flux, equilibrium temperature, diffusivity and surface heat loss on the temperatures of the lake are studied in detail using a one-dimensional transient model. The governing equations are solved numerically using finite differences method. The results of this work show the transient temperature distribution in the lake over the year and the variation in temperatures due to external changes in the environment.

▼ In this work, I deal with the question of how one ought to live and raise children in the context; of environmental catastrophe. I tell several stories about my experiences as a Peace Corps volunteer in The Republic of Kiribati and about the process of becoming a father. I find that while disasters like climate change are too far advanced for human beings to avoid some very disturbing consequences, we can, through storytelling, deal with those losses by making sure they are not forgotten. I conclude that personal stories about fear, loss, tragedy and hope are part of the process of healing wounds inflicted by tragedy and that it is imperative that these stories be passed on to younger generations lest they lose their capacity for empathy.

▼ Tropical mountains are the most biodiverse terrestrial systems on Earth. This "megadiversity" is largely because tropical montane species inhabit narrow elevational distributions-understanding why tropical mountains are so biodiverse thus requires understanding the factors that explain elevational specialization. In my dissertation, I explored the role of two factors previously hypothesized to explain why tropical birds inhabit narrow elevational zones-temperature and interspecific competition. In Chapter 1, I describe resurveys of New Guinean montane bird communities originally surveyed by Jared Diamond in the 1960s, and demonstrate rapid
warming-associated upslope shifts in these avifaunas. In Chapter 2, I test the hypothesis that these recent upslope shifts are the result of thermal specialization in New Guinean montane birds. However, I find no evidence that species' exhibit local adaptation to ambient temperature in their thermal physiology (lower critical temperatures and thermal conductances), suggesting New Guinean montane birds' elevational limits are minimally influenced by thermal specialization. I then use a comparative approach in Chapter 3 to test whether species exhibit local adaptation to cold high elevation environments in body size, and find little evidence that body size clines are positively linked to elevation in both intraspecific and interspecific analyses. These analyses suggest that temperature may primarily exert an indirect influence on tropical birds' elevational distributions (e.g., by altering biotic interactions with prey, predators or competitors). One biotic interaction hypothesized to be important in tropical montane avifaunas is interspecific competition, which has been argued to explain why a common pattern is for closely related species to inhabit different elevational zones in a "layer cake" pattern. In Chapter 4, I find broad support for a model of community assembly wherein competitive interactions upon secondary contact drive elevational divergence between sister species of tropical montane birds. I move from evolutionary pattern to ecological process in Chapter 5, where I test the hypothesis that interference competition is a mechanism limiting species' elevational distributions. Playback experiments in five species-pairs of New Guinean songbirds with "layer cake" patterns revealed strong interspecific aggression in all cases where species-pairs interact with their putative competitors, providing experimental data consistent with the hypothesis that interspecific competition is a factor limiting these species' elevational distributions.

▼ Research Doctorate - Doctor of Philosophy (PhD)
In recent years, increasing concern over global warming and climate change and its connection to CO2 emissions have received huge attention worldwide. The alarming rise in CO2 levels and escalating demand for cleaner energy has lead to the development of novel technologies that may play a major role in addressing the issues related to CO2 emissions. Some of these technologies aim at reducing CO2 emissions by capturing and sequestrating it. Development of carbon abatement technologies, usually referred to as carbon capture and storage (CCS) technologies enables substantial reduction in CO2 emissions but still using fossil fuels. In conventional coal power plants, recovery of CO2 is energy intensive because of the low concentration of CO2 in the flue gas, which is due to the dilution by N2 in air. The concentration of CO2 can be increased and thereby the cost of CO2 recovery can be reduced by removing the nitrogen in the air before entering the furnace. Therefore, in oxy-fuel technology, combustion of coal takes place in the presence of pure oxygen and flue gas that is recycled from the furnace exit to moderate the temperature of the combustion process and for effective heat transfer. Techno-economic feasibility studies that have compared different CCS technologies have declared that oxy-fuel technology emerges as a favourable option among the CCS technologies that are close to commercialization. Apart from the capability to produce a highly concentrated CO2 stream, this technology has also been credited for its flexibility, as it can be adapted in new designs or used to retrofit existing coal fired (p.f.) power plants. Review of the literature shows that the change from air to oxy-fuel mode modifies the gas composition inside the furnace that leads to an altered temperature, species and heat transfer profiles causing undesirable effects inside an oxy-fired furnace. The difference in the combustion behaviour in an oxy-fuel furnace compared to conventional systems is summarized in the literature as due to the difference in the thermo-physical properties of the bulk gas (either N2 or CO2) and due to the change in the near burner aerodynamics caused due to different throughputs in air and oxy-fuel combustors. Extensive research work has been carried out in this novel mode of combustion, establishing the issues and addressing solutions. More research is needed especially on issues like ignition and devolatilization, as stable combustion in pulverized coal combustion system is ensured by the rapid volatile release, ignition and heat released during devolatilization. Therefore issues related to ignition and devolatilization is considered most important and requires continuous intensive research to take this technology to the next phase of commercialization. It has also been proposed by many researchers that undesirable behaviour…

▼ Heat flow measurements may require correction for both recent
warming and post-glacial
warming signals.
Warming during the last century can be detected in borehole temperature profiles. Both climate
warming signals during the past century and post-glacial
warming signals during the past 10 millennia are greatest near the surface and diminish with depth. Both atmospheric data and borehole temperature data show that recent
warming varies systematically with latitude along a north-south transect in the United States. The systematic increase with latitude from +0.7 °C at 41.6oN to +2.3 °C at 49oN during the last century is consistent with the prediction that
global warming due to increasing amount of CO2 in the atmosphere varies with latitude. A systematic increase of heat flow with depth is predicted to result from the post glacial
warming signal in the upper 2km. A modeled depth dependent correction of post glacial
warming indicated that the thermal gradient may be underestimated by 27% in some areas, thereby implying that some heat flow values in the United States may be up to 27% higher depending on the depth of the temperature gradient measurement. Averaging the corrected heat flow values shows that the average heat flow is 58 mW m-2, 78 mW m-2 and 51 mW m-2 for the whole conterminous United States, Western and Eastern United States respectively.

▼ Carbon dioxide (CO2) is seen as one of the major
global contributors to
global warming.
CO2 is produced naturally in the environment, however, with the advent of climate change,
CO2 emissions from manmade sources has come under scrutiny as a driver of manmade
climate change. Combustion of fossil fuels and related practices is seen as the primary
source of such emissions. Current CO2 capture technologies tend to be limited by cost and effectiveness.
The basis of this project was to design a novel adsorbent material capable of removing
significant levels of CO2 from gaseous streams. As a fundamental requirement, the
developed adsorbent material was synthesised using economically viable materials, such as
amine modified microporous zeolites which have not been extensively studied to date
compared to amine modified mesoporous solids such as SBA-15. This study looks primarily
at CO2 adsorption from low temperature exhaust streams with two primary factors of
interest; CO2 adsorption capacity and regeneration energy requirements.
Various microporous solids, including zeolite-Y and zeolite- , were chosen with the view of
examining their potential as supports for liquid amine. A number of techniques were
employed for surface modification and subsequently tested using a gas adsorption rig with
online mass spectrometry. The most successful technique for synthesising amine modified
adsorption, which showed preferable properties in terms of CO2 adsorption and
regeneration, was chosen for further testing. The solid which performed best during CO2
adsorption/desorption testing was aminopropyltriethoxysilane (APTES) modified zeolite -
25, prepared using a amine solution impregnation technique whereby APTES was dissolved
in toluene, zeolite- was then added to the mixture and subsequently heat treated. This solid
was found to have a CO2 adsorption capacity of 216 mg CO2 g-1 solid adsorbent.
Other factors investigated included the effects of silica-alumina ratios on amine
functionalisation, the effects of surface pre-treatments, such as acid treatment, in boosting
surface modification and finally, the use of alternative amines to modify microporous solids.
These tests showed that with decreasing silica/alumina ratio the adsorption capacity of each
solid similarly decreased. Dilute acid pre-treatment was found to boost surface hydroxyl
groups for subsequent amine bonding in some samples. The weight percentage amine
loading of solid supports was also found to be an important factor as too much amine was
found to be detrimental to the CO2 adsorption properties.
A number of amine modified mesoporous materials were also prepared for comparative
purposes. APTES, polyethyleneimine (PEI) and tetraethylenepentamine (TEPA) were used
to modify a number of MCM-type mesoporous silicas. MCM-41 and porous silica spheres
were synthesised for this investigation. The TEPA modified MCM-41 samples produced an
adsorbent with the most favourable CO2 adsorption/desorption properties. The adsorption
capacities obtained were up to 196 mg CO2 g-1 for…

▼ Food production requires large amount of resources
and is responsible for significant environmental impacts. One means
to reduce these impacts is for consumers to change their diet, by
selecting more sustainable food products. However, this is not a
trivial task due to the variety of diets, food products and the
need for behavioural change. This project considers how low-carbon
diets could be achieved in an optimal way, requiring least
departure from current diets and providing the required nutritional
value. Multi-objective optimisation has been used for these
purposes, considering
global warming potential (GWP) and
nutritional value of food and dietary changes that may be required.
Focusing on the British case, three types of diet - one where all
products including meat can be included, vegetarian and vegan - are
considered and compared with the current diet. The results suggest
significant reductions in GWP are possible if consumers are willing
to change their diets, with reductions up to 50% being considered
feasible. The results also suggest that changing the diet to meet
government advice on nutrient intakes alone could lead to 5%
reductions in the GWP of the diets for men, and 18% for women.
Slightly greater changes to the diet, over and above those required
to make the diet healthy, would result in much greater reductions
in GWP (up to approximately 50%) whilst still being relatively easy
to achieve. These changes include reducing or eliminating
consumption of cheese, red meat and products high in sugar and fat.
Changing to a vegetarian diet would reduce the GWP by 54% for men
and 58% for women and changing to a vegan diet would reduce the GWP
by 74% for both men and women on the current diet but would require
drastic changes in consumer behaviour. Following government
Eating-well Guide reduces the impact by 20% for men and 30% for
women but it also requires significant behavioural changes. The
findings of this project will be useful for those interested in
promoting or following a healthy and low-carbon diets, including
policy makers and consumers.

During the last century hydroenergy become
one of the most important energy source in the world. However, the
environmental impacts of dams have been disccused widely in recent
years. Number of reserches indicates dams reservoir as an
significant greenhouse gas source. The objective of this research
was to evaluate the effects on environment made by electrical dams
in country of flatlands. To assess all possible impact of designed
power plants, analysis of more than 80 working electrical dams has
been made. The impact of small and large power plants was
considered. Analysis shows that there was a quite big difference in
flooded land area per energy unit (kW), between low-power and
high-power hydroelectric. Average flooded area for 100 kW power
plant destroys over 0,5 hectare of species rich semi-natural
grasslands forests and other landed property. When high-power
(100MW) hydroelectric dam require only about 0,06 hectare of
flooded land per unit. Thus, indicates that small water-plants
gives much more negative impact per unit, than big ones. However,
the impact of dams, are highly destructive in conditions of
flatlands. Results has showed that further hydroenergy development
in Lithuania, according to planned “Lithuanian hydroenergy resource
use scheme” would require vast flooded area of total 670 km2. In
addition, dams reservoir emit a significant amount of greenhouse

▼ Climate changes refer to any substantial changes in measures of climate
lasting for an extended period. One the important ways to track and investigate
the causes and effects of climate change is through the use of indicators,
like sea surface temperature (SST). Thus, the main aim of this dissertation
is to understand the impacts of climate changes in future SST variability with
analysis of SST data from
global climate models (GCMs) of CMIP5 project.
The methodology adopted comprised two fundamental steps: 1) worldwide
SST data division in regions with K-means cluster and validation of CMIP5
models with a comparative analysis between SST data of CGMs of CMIP5 and
SST data of Era Interim reanalysis; 2) calculate differences between future
(2070-2100 and 2020-2050) and historical (1975-2005) SST data for RCP4.5
and RCP 8.5 climatic scenarios, and compute trends between 1975 and 2100
for both RCP scenarios.
SST data of CGMs of CMIP5 are divided into eight regions. Most of GCMs of
CMIP5 have a good SST reproducibility. North Hemisphere regions present
a higher thermal amplitude when compared with equivalent regions of South
Hemisphere. The differences between long-term future and historical regime
are larger than differences between near-term future and historical regime. For
long-term future, worldwide SST has mean increments of 2.46 °C and 1.35
oC for RCP 8.5 and RCP 4.5 scenarios, respectively. For near-term future,
SST has mean increments of 0.86 °C and 0.73 °C for RCP 8.5 and RCP 4.5
scenarios, respectively. Polar Regions present higher percentual variability,
being possible to conclude that Polar Regions will have larger changes,
reflecting an overheating on these regions. For RCP 8.5 scenario, SST trends
are 4.34 °C/dec (maximum) and 1.64 °C/dec (minimum) for north sub-tropical
region (STRN) and south polar region (PRS), respectively. Regarding RCP 4.5
scenario, SST trends are 2.64 °C/dec (maximum) and 0.94 °C/dec (minimum)
for STRN and PRS, respectively. From this work it can be concluded that is
not possible to select only one
global model, since each has its advantages.
North Hemisphere will present higher SST trends. Overall, this thesis analysis
has revealed that SST will increase worldwide, however, this depends on the
different globe locations

Pilot-Scale Evaluation Of Advanced Solvents For CO2 Capture From Coal-Fired Utilities.

▼ In 1992, international concern about climate change (a change to Earth's climate, especially those produced by
global warming) led to the United Nations Framework Convention on Climate Change (UNFCCC). The ultimate objective of that convention was the "stabilization of greenhouse gas concentrations in the atmosphere at a level that mitigates anthropogenic interference with the climate system" (1). There has been a growing concern about
global climate change which scientists believe is (arguably) caused mainly by anthropogenic emission of greenhouse gases (GHGs) into the atmosphere. The overall goal of this work was to evaluate next generation solvents at a pilot scale level to determine the advantages and disadvantages these advanced solvent have over the current industry standard. To accomplish this goal a pilot scale system was designed and fabricated on the back end of the Energy and Environmental Research Center's Combustion Test Facility. The system was used to evaluate six solvents which included Hitachi's H3-1, MDEA/Piperazine, Huntsman's Jeff Treat XP, MEA and two others. Because of the proprietary nature of these solvents not all information can be shared.
It was determined that advanced solvents are the best available technology for implementing CO2 capture at the large scale. Advanced solvents will be the technology that will make it to the market place sooner than other technologies due to the long time use of amine solvents in the oil and gas industry for their removal of CO2. For the case of postcombustion capture, the main conclusions are that 90% CO2 capture can be met with MEA and advanced solvents. The EERC system was able to capture at least 90% of the CO2 present in the flue gas for each advanced solvent and the baseline MEA. Results of the testing indicate that the use of advanced solvents, such as H3-1, can reduce the cost of capture considerably.
Data from the advanced solvents and MEA tests conducted show that for similar test conditions, MEA required about 10-40% more regeneration energy input to achieve 90% CO2 capture than the advanced amine-based solvents. H3-1 required the lowest heat input (~1475 Btu/lb CO2), and the reboiler duty for MDEA+PZ was ~1600 Btu/lb CO2. The regeneration energy requirement for MEA was estimated to be in the range of 1775-1940 Btu/lb CO2 captured. The MEA case required a 30% to 50% higher solvent flow rate than H3-1 to attain 90% CO2 capture for a given amount of treated flue gas. Conversely, tests on MDEA+PZ showed a solvent usage about 135% higher than MEA to reach 90% capture. Consequently, use of H3-1 for a large-scale process could lead to significant economic benefits over MEA and MDEA+PZ. Lower solvent flow rates require smaller pumps and less energy to pump the solvent through the columns.
Advanced solvents show promise, but improvements will still need to be made to reduce capital and operating costs to make the technology economically feasible for today's market. Advanced contactors and solvent promoters will be technologies…

▼ The IPCC and UN FAO have both suggested a
global reduction in meat consumption to reduce greenhouse gas emissions. But how do nations and citizens resolve tensions between ecological stewardship and meat consumption? What is implied in eating meat and raising livestock in a country where the historical imaginary yokes national values to the pig-producing countryside? To answer these questions, this dissertation examines how climate change is affecting meat consumption and production logics in Denmark. Though the country has a reputation for progressive environmental policy, its formerly large agricultural sector continues to exert disproportionate political influence, and many citizens consider pork its most "traditional" food. In 2016, a publicly-funded advisory council issued a report suggesting that parliament pass a beef tax to reduce consumption and reflect its environmental impact. The report was the most controversial the council had ever issued, with members receiving angry phone calls and politicians arguing the council should be disbanded. The proposal put national tensions between sustainability and agriculture in full view, and it became clear that such a tax would not be passed. Based on 16 months of fieldwork with meat industry workers, food innovation NGOs, environmental activists, and animal rights advocates, this dissertation explores how stakeholders in the meat-climate debate produce and enact knowledge; while industry scientists used quantification as a stand-in for making ethical claims, NGOs attempted to make new environmental subjects through educational eating programs and pressure campaigns to increase availability of plant-based foods. These efforts are contrasted with activists who work directly with animals, whose work is biopolitical and affective. All actors claim to be in favor of "environmental sustainability" but are governed by conflicting internal regimes and motivations. What emerged was a hydra of anxieties not just about climate but human-animal relationships in general, that I call "hyperanimal."

▼ Les tempĂ©ratures Ă©levĂ©es et le dĂ©ficit de l'eau rĂ©sultant du changement climatique peuvent considĂ©rablement influencer la croissance et le dĂ©veloppement des plantes ainsi que leur sensibilitĂ© aux agents pathogènes. Dans cette situation, l'agriculture doit mieux s’adapter aux changements climatiques.Dans ce contexte, certaines bactĂ©ries de type PGPR (Plant Growth Promoting Rhizobacteria) sont capables de protĂ©ger les plantes contre des stress biotiques et/ou abiotiques. Il a Ă©tĂ© montrĂ©, au laboratoire que la bactĂ©rie PGPR, Paraburkholderia phytofirmans confĂ©rait Ă la vigne, une meilleure tolĂ©rance aux basses tempĂ©ratures. Cette protection s’explique en partie par le maintien de la photosynthèse et une augmentation des teneurs en sucres solubles.Au cours de ce travail, nous avons utilisĂ© la bactĂ©rie, P. phytofirmans pour induire une tolĂ©rance Ă la chaleur chez la tomate dans le but d’anticiper les effets d’un rĂ©chauffement climatique. Les objectifs du travail Ă©taient de caractĂ©riser d’un point de vue agronomique, biochimique, physiologique et molĂ©culaire l’impact de la bactĂ©rie sur la plante en condition de stress thermique.Les rĂ©sultats de cette Ă©tude ont dĂ©montrĂ© l’importance de l’utilisation de P. phytofirmans souche PsJN comme agent biologique en particulier vis Ă vis d’un rĂ©chauffement climatique. Ces rĂ©sultats permettront de rĂ©pondre aux attentes des sĂ©lectionneurs de tomates qui visent Ă dĂ©velopper une productivitĂ© accrue respectueuse de l’environnement tout en offrant une meilleure tolĂ©rance aux stress biotiques et abiotiques.
High temperatures resulting from climate change can significantly influence plant growth, development, and susceptibility to pathogens. In this situation, agriculture needs to better adapt to climate change.In this context, certain Plant Growth Promoting Rhizobacteria (PGPR) are able to protect plants against biotic and/or abiotic stresses. It has been shown in the laboratory that the PGPR bacterium, Paraburkholderia phytofirmans strain PsJN, gives the grapevine a better tolerance under low temperatures. This protection is partly attributed to the modulation of carbohydrate metabolism through the maintenance of photosynthesis and an increase of soluble sugars levels.During this work, the bacterium P. phytofirmans was used to induce heat tolerance to tomato plants to anticipate the global warming effects. The objectives of the work were to characterize, from an agronomic, biochemical, physiological and molecular point of view, the impact of the bacteria on the plant response under heat stress conditions.The results of this study demonstrated the importance of the use of P. phytofirmans strain PsJN as a biological agent especially with respect to global warming. These results will meet the expectations of tomato breeders who aim to develop increased productivity while respecting the environment and offering a better tolerance to biotic and abiotic stresses.

▼ Ph.D. University of Hawaii at Manoa 2012.
Precipitation and atmospheric circulation changes in response to global warming have profound impacts on the environment for life but are highly uncertain. This study investigates fundamental mechanisms controlling these changes and relates them to the effects of sea surface temperature (SST) change, using Coupled Model Intercomparison Project simulations. The SST warming is decomposed into a spatially uniform SST increase (SUSI) and deviations from it.
The SST pattern effect is found important in explaining both the multi-model ensemble mean distribution and inter-model variability of rainfall change over tropical oceans. In ensemble mean, the annual rainfall change follows a "warmer-getwetter" pattern, increasing where the SST warming exceeds the tropical mean, and vice versa. Two SST patterns stand out: an equatorial peak that anchors a local precipitation increase, and a meridional dipole mode with increased rainfall and weakened trade winds over the warmer hemisphere. These two modes of inter-model variability in SST account for up to one third of inter-model spread in rainfall projection.
Tropospheric warming follows the moist adiabat in the tropics, and static stability increases globally. A diagnostic framework is developed based on a linear baroclinic model (LBM) of the atmosphere. The mean advection of stratification change (MASC) by climatological vertical motion, often neglected in interannual variability, is an important thermodynamic term for global warming. MASC and SST pattern effects are on the same order of magnitude in LBM simulations. Once MASC effect is included, LBM shows skills in reproducing general circulation model (GCM) results by prescribing latent heating diagnosed from the GCMs.
Common to all GCMs, MASC causes both the Hadley and Walker circulation to slow down as articulated by previous studies. The weakening of the Walker circulation is robust across models as the SST pattern effect is weak. The Hadley circulation change, by contrast, is significantly affected by SST warming patterns. As a result, near and south of the equator, the Hadley circulation change is weak in the multi-model ensemble mean and subject to large inter-model variability due to the differences in SST warming patterns, explaining up to four fifth of the inter-model variability in changes of the overturning circulation.

▼ In this dissertation, I investigate the determinants on Americans’ perceptions of global warming and individuals’ environmentally significant behaviors to reduce global warming. Specially, I examine how contextual variables, primarily represented by local weather and climate, attitudinal variables, and socio-demographic characteristics affect public opinion towards global warming, personal voluntary actions and willingness to address global warming. The research of this dissertation reveals some important findings. First, local weather and climate—represented by long-term temperature trends—is found to have significant effects on public perceptions of global warming and private-sector environmentally significant behaviors. In particular, the summer temperature trend over the past 10 years has consistently shown to have positive effects on public acceptance of anthropogenic global warming and concern for global warming. In other words, individuals are most sensitive to summer temperature and more likely to translate increasingly hot summers into perceptions of anthropogenic global warming and their concern for this issue. Second, consistent with the results of previous studies, global warming has become a politically polarized issue. Specifically, Democrats and political liberals are more likely than Republicans and political conservatives to accept the notion of anthropogenic global warming, show higher level of concern for global warming, and participate in private-sector environmentally significant behaviors to reduce global warming. Third, attitudinal variables play an important role in affecting public perceptions of global warming and individuals’ environmentally significant behaviors. For instance, personal attitudes toward scientists are found to be a strong group of predictors on public opinion toward global warming. In addition, attitudinal variables—including individuals’ environmental views and perceptions of global warming—outperform socio-demographic characteristics and contextual forces in explaining the variance of personal actions and public willingness to pay more to reduce global warming. Finally, objective macro-economic conditions, represented by county-level unemployment rate in this dissertation are not found to have any consistently significant effect on either public perceptions of global warming or individuals’ environmentally significant behaviors.

Thailand has responded to global warming with strategies of mitigation and adaptation. Green campaigns targeting citizens have not significantly improved environmental behaviours, particularly in the Bangkok metropolitan area. This research identifies and analyses the frames held by global warming experts in Thailand and those used in the Bangkok Metropolitan Administration (BMA) environmental campaign as well as frames reported by target audience members before and after the campaign. All frames were compared to identify campaign effectiveness based on their consistency. The use of framing theory in this way to evaluate campaigns is innovative and bridges between different traditions as well as research methods in the field of communication studies. In-depth interviews with experts showed the dominant frames to be Social Frames. The most common frames found in campaign materials were Financial Frames. A survey of target audience members demonstrated the relationship between frames held before and after the campaign and that the Scientific Frame was the one mostly reported. An integrative analysis showed an inconsistency of frames in three main elements in this campaign communication which contributed to its ineffectiveness in encouraging citizens' change of behaviour. It is argued that Global Warming Campaigns in Bangkok that combine existing traditional frames (e.g. Buddhism and King's Philosophy of Sufficient Economy Frames) and perceived global warming frames (e.g. Scientific Frames) can engender better responses in dealing with this issue particularly among residents in Bangkok. The approach to framing analysis in this project can be applied to the study of other kinds of campaign communication in the wider Thai context.

▼ Global warming is an overarching issue worldwide that has caused an increase in extreme weather events and coastal flooding, impacted food security, and created a loss of both biodiversity and unique ecosystems. Certain regions around the world appear to be more proactive in the fight to reverse, or at least contain, the effects of
global warming. One such area is California that is currently implementing the
Global Warming Solutions Act to minimize the main source of
global warming: greenhouse gas emissions.
The purpose of this research paper is to assess the effectiveness of programs and resources implemented under the
Global Warming Solutions Act to predict its success in reducing emissions to specific levels by 2020, as promised in the Act's framework.
The research method will include interviews to collect qualitative data from government agencies implementing programs and/or providing resources related to the Act. Quantitative data will also be collected through surveys administered to students and faculty on the implementation team for the California State University, Northridge Climate Action Plan and also those teaching and studying under its Institute of Stability.
Data collected will be used to determine relationships between the policy's programs and resources to assess their effectiveness or ineffectiveness. The results will help predict the overall probability of the
Global Warming Solution Act's ability to fulfill its commitment to reduce greenhouse gas levels in California to what they were in 1990, by next year (California Air Resources Board, 2018).

▼ Both drought and aridity indicate an imbalance in water availability. While drought is a natural temporal hazard, aridity is a constant climatic feature. The purpose of this thesis is to reveal how
global warming affects drought and aridity in order to find a proper method to estimate aridity and drought under a changing climate. First, past probable changes in aridity are investigated using published literature, trend analysis, and clustering. The results suggest that arid zones are becoming slightly more humid and vice versa. The trend in aridity changed, or even reversed, around 1980 in most parts of the world. We speculate that the reason for this is the dramatic change (rise) in
global temperature around 1980 which, in turn, caused similar trends for Potential Evapotranspiration (PET).Possible changes in the future aridity are then analysed by employing bias-corrected simulations of 22
global climate models. The results suggest that climate change will alter the expansion of aridity zones in the future which is mostly due to positive PET trends, albeit the slight increase in precipitation will lessen that. Next, to verify the importance of PET as a means to better assess drought in a
warming climate, as observed for aridity, drought trends in different aridity zones are surveyed with and without PET consideration. Given the known changes to PET in observed records, and expected increases as
global warming intensifies, the results suggest that in the face of climate change, PET should not be ignored in drought modelling.Finally, we show that while precipitation-based drought indexes can underestimate future drought, PET-based indexes overestimate drought, as they assume greater evaporation than actually occurs. We introduce the Actual evapotranspiration Drought Index (ADI) that uses precipitation and actual evapotranspiration to quantify drought. ADI offers a more realistic representation of drought occurrence than other measures, and assumes special importance in a
warming climate, given its consideration of the changed evaporation profile a warmer future will bring. In conclusion, the thesis presents a new framework to appropriately assess droughts in a non-stationary climate. The basic concepts of the approach can also be used for aridity assessments.

▼ Wetlands impact
global warming by regulating the exchange of greenhouse
gases (GHGs), including carbon dioxide (CO2), methane (CH4), and nitrous oxide
(N2O) with the atmosphere. Few studies have investigated the interactive effects of
different environmental factors in wetlands, such as water residence time and nutrient
inflows, on GHG emissions. Here we investigated GHG emission in Great Lakes
coastal wetlands across various hydrology, temperature, and N inflow regimes using a
process-based simulation model MONDRIAN. We found the emission of CH4, N2O
and sequestration of C (i.e. negative net ecosystem exchange, NEE) all increased with
increasing water residence time and N inflow in our modeling results, primarily
driven by increased plant productivity and N uptake, which indicated greater C and N
cycling rates in the model. The summed
global warming potential (GWP) (i.e. sum
GWP of CH4, N2O, and NEE) of wetlands on 20-year and 100-year time horizons
were both primarily driven by CH4 emissions. Under most conditions, NEE reduced
by removing atmosphere C in our results, meaning modeled wetlands were net sinks
of carbon as wetland plants assimilated atmospheric CO2 and plant litter became
accreted in underlying anaerobic soil. Negative effects of NEE on GWP partially
offset the GWP of CH4 emissions. GWP of N2O was negligible because the amount
2
of N2O emitted from these simulated wetlands was very small. Our results suggested
that under a wide range of conditions, the summed GWP from Great Lakes coastal
wetlands may be strongly controlled by the tradeoffs among CH4 emission and CO2
sequestration, both of which were driven by elevated levels of N inflow in our
simulations. Water level scenarios also had an effect on GHG exchanges by
moderating the transitions between aerobic and anaerobic conditions. Higher
temperature promoted higher GWP but under the modest range of temperature
increases we simulated, reflecting those expected in this region by midcentury,
temperature effects were minimal compared with those of other factors. These results
highlight the previously understated role of nutrients in modulating GWP in coastal
wetlands and point out the importance of water residence time in wetlands N cycling.

▼ National Geographic is a magazine that inspires people to care about the planet through its articles of exploration, education, and conservation. Magazines are a significant source of knowledge and compete with a variety of other media, constantly rethinking where they can improve in comparison to other media. Research in this dissertation shows that some magazines offer high quality imagery for artwork, photos and advertisements, which remains critical for industries and readers. They often offer greater depth than radio, TV, or even newspapers, so that people interested in an analysis of news and events still depend on magazines for informative and general news. People often turn to media—such as television, newspapers, magazines, radio, and Internet—to help them make sense of the many complexities relating to environmental science and governance that (un)consciously shape our lives.
Global warming, as a
subject, demands both political and personal responses in all parts of the world, and effective decision making at both scales depends on timely, accurate information, according to Shanahan (2009:145). The quality and quantity of journalism about climate change will therefore be key in the coming years. National Geographic comprises a variety of themes, such as environment, science, wildlife, travel and photography. This study is an analysis of the writing and photography related to one theme -
global warming. It provides a critical analysis of the coverage of the
global warming discourse in one magazine, examined over an eleven-year period from 2000 to 2010. This theme is powerful in that it represents ethical responsibility and concern for nature and our world and the analysis attempts to define the objects of discourse within the coverage, thus, evaluating if the format of the coverage informs and educates the audience about
global warming

▼ This study examined the effects of
global warming on sugar cane farming in Tongaat Huletts –Tambankulu Estates in Swaziland, from the period of 2010 to 2015. The researcher adopted the conceptual and theoretical framework related to
Global Warming and sugarcane production. Both quantitative and qualitative methods were utilised to capture the effects of
global warming on cane production. In particular, the Ricardian production model and thematic analysis were adopted in the study. The study utilised monthly and yearly time series data for the period of 2010 to 2015, collected from Tongaat Huletts Tambankulu Estates, Swaziland.
The findings disclose significant non-linear effects of
global warming on sugarcane production in Tongaat Huletts Tambankulu Estates, Swaziland. Observations were that sugarcane production has directly been affected by changes in
global warming conditions.
Global warming variables such as radiation, temperature and rainfall have negatively affected sugarcane production. The findings showed that for every additional degree in the celsius of temperature, the expected sugarcane production decreases on average, while holding other variables constant. Moreover, for every additional millimetre of rainfall, the expected sugarcane production decreases, and for every additional degree of radiation increase, the expected sugarcane production decreases.
In contrast, the findings revealed that the combination of water use of commercially rain-fed and irrigated sugarcane and increases sun appear, have positive effects on sugarcane production. For every millimetre in combination of water use of commercially rain-fed and irrigated sugarcane, the expected sugarcane production increases. Similar for every additional sun hours, the expected sugarcane production increases.
The findings also revealed that management ought to enhance and improve their knowledge and awareness of
global warming and its impact on sugarcane production for better, all including holistic approach to mitigate this threat, especially during critical peak season. The study suggests that strategies adopted to mitigate the threat focus on farming practices that promote sugarcane production regardless of the dangers posed by higher levels of
global warming variables (temperature, rainfall, and radiation).

▼ This dissertation focuses on quantifying the physical processes in the Labrador Sea, such as wintertime deep convections, subsequent restratification, and the mesoscale eddy activities. The Labrador Sea is one of the areas where deep ocean is
warming since 1998, so it has an implication on the recent
global surface
warming slow-down, which is also termed the
global warming “hiatus”. The restratification after the 2008 deep convection is studied using regional ocean model. The modeled mixed layer depth during wintertime resembles the ARGO observed mixed layer very well, and the lateral heat flux during the subsequent restratification is in line with observations. The Irminger Rings (IRs) are reproduced with fresher caps, and they are identified and tracked automatically. The model underestimates both the number of IRs into the convection area and the heat they carry. The underestimation is most likely caused by the errors in the direction of the West Greenland currents (WGC) in the model, which causes more IRs propagating westward. Yet, the model still observed three eddies propagating into the convection area during restratification phase in 2008, and they contribute from 1 to 4% of the total heat regain during central Labrador Sea restratification. Then a merged along track altimeter dataset is used to study the variability of eddy kinetic energy (EKE) in the Labrador Sea from 1993 to 2012. The WGC EKE propagates far into the central Labrador Sea during occasional years, and its annual cycle magnitude declines. The decreasing annual cycle is related to the central basin convections, while the WGC EKE strengths is controlled by a low frequency variation of the wind stress curl, which is related to the subpolar gyre (SPG) circulation. Finally, the subpolar North Atlantic (SPNA)
warming during the recent
global warming slow-down is studied by separately investigating the subsurface
warming of the eastern and western SPNA. Temperature decompositions indicate buoyancy domination in the west, and wind stress forcing domination in the east prior hiatus period, and the contrary during the hiatus period. Atlantic Multidecadal Oscillation only shows shallow influence in the west SPNA.

▼ Esta pesquisa procura reunir provas e evidĂŞncias cientĂficas contrárias Ă hipĂłtese do aquecimento global antropogĂŞnico e elucidar seu significado na atualidade. Argumentamos que o clima está em permanente transformação, nĂŁo podendo ser reduzido a um produto de variações das concentrações atmosfĂ©ricas de diĂłxido de carbono e que a preocupação com mudanças climáticas nĂŁo Ă© uma novidade histĂłrica mas, apesar disso, nosso desconhecimento sobre o funcionamento do sistema climático Ă© ainda desafiador. ConcluĂmos que a hipĂłtese do aquecimento global antropogĂŞnico nĂŁo Ă© consensual e exerce hoje a função de ideologia legitimadora do capitalismo tardio, perpetuando a exclusĂŁo social travestindo-se de compromisso com as gerações futuras.
This research aims to gather scientific proofs and evidences against anthropogenic global warming hypothesis and to elucidate its meaning in the present. We argue that climate is in a permanent transformation, not resuming itself to a product of atmospheric carbon dioxide concentration variations and that worries about climatic changes are not new but, despite this, our ignorance on the functioning of the climate system is still challenging. We conclude that anthropogenic global warming hypothesis is not consensual and exerts nowadays the function of late capitalism legitimating ideology, perpetuating social exclusion transvestiting itself as a commitment to future generations.

▼ Para medir o impacto de mudanças climáticas, acompanhadas variações do investimento agrĂcola, sobre a atividade agrĂcola brasileira, foram estimadas conjuntamente funções de receita e de custo de produtos e insumos agrĂcolas. Estas foram derivadas de uma função de lucro restrita, condicional a variáveis de clima e investimento. A pesquisa inova pela metodologia, diferente das demais empregadas anteriormente para o caso brasileiro, pela maior precisĂŁo dos dados de clima e pela inclusĂŁo do investimento agrĂcola como variável de mitigação dos efeitos gerados pela variação climática. Os resultados mostraram uma redução da lucratividade agrĂcola para o Brasil com o aumento da temperatura e precipitação no longo prazo, apesar de variarem conforme regiões. SaĂram beneficiadas regiões mais ricas, em detrimento das mais pobres, cuja maior parte da produção agrĂcola Ă© voltada para a subsistĂŞncia. O investimento agrĂcola atuou como redutor desta tendĂŞncia, de crescimento da desigualdade agrĂcola, ajudando a reverter apenas parcialmente o efeito do aquecimento.
To measure the impact of climate changes along with changes in agricultural investments in Brazil\'s agricultural sector, this paper jointly estimates revenue functions for the outputs and cost functions for the inputs. These equations were derived from a restricted profit function conditional to climate and investment variables. The paper innovates by using the profit function approach to study Brazils agricultural sector. It also brings more precise data and adds investment as a relevant variable in the model. Results show a reduction in profitability as temperature and precipitation grow, but they are not homogeneous amongst the different regions. Richer regions seem to do better than the poor ones, which have a large part of their production focused on subsistence. Investment seems to act as a counterbalance to this trend of increasing agricultural inequality, partially reverting the global warming effects.
