Aquatic macroinvertebrates are important for many ecological processes within river ecosystems and, as a result, their abundance and diversity are considered indicators of water quality and ecosystem health. Macroinvertebrates can be classified into functional feeding groups (FFG) based on morphological-behavioral adaptations. FFG ratios can shift due to changes in normal disturbance patterns, such as changes in precipitation, and from human impact. Due to their increased sensitivity to environmental changes, it has become more important to protect and monitor aquatic and riparian communities in arid regions as climate change continues to intensify. Therefore, the diversity and richness of macroinvertebrate FFGs before and after monsoon and winter storm seasons were analyzed to determine the effect of flow-related disturbances. Ecosystem size was also considered, as watershed area has been shown to affect macroinvertebrate diversity. There was no strong support for flow-related disturbance or ecosystem size on macroinvertebrate diversity and richness. This may indicate a need to explore other parameters of macroinvertebrate community assembly. Establishing how disturbance affects aquatic macroinvertebrate communities will provide a key understanding as to what the stream communities will look like in the future, as anthropogenic impacts continue to affect more vulnerable ecosystems.

Climate change presents a significant threat to human health, both mental and physical; as a result, it has become one of the most commonly discussed phenomena of the 21st century. As many people are aware, a wide range of social and physical factors affects mental health. However, many people fail to realize that these increases global temperatures also have a significant impact on mental health as a result of increased vulnerability that is often manifested through one's emotions. By analyzing perceptions of people across the globe, in the United Kingdom, New Zealand, and Fiji, we were able to pinpoint these emotions and trace them individual's feelings of worry, distress, and hope that resulted from their perceived impacts on climate change. Overall, we found that people tend to have overall more negative emotional reaction when it comes to the perceived effects of climate change. Of the respondents, more men than women expressed concern regarding the various negative implications. Finally, those in the United Kingdom exhibited a stronger emotional response, followed by those in New Zealand and Fiji, respectively.

This thesis analyzes the implications of climate change for insect-borne diseases in humans, focusing especially on mosquitoes and ticks as the two most common vectors. I first introduce relevant background on climate change, arthropod vectors, and the diseases they carry, and the significance of vector-borne diseases for human health. I report on current knowledge of spatial and temporal trends in most common mosquito and tick-borne diseases in the United States, with a detailed table provided in Appendix A. I then review how climatic variability is anticipated to cause profound changes in vector life cycles. In particular, the rise in global ambient temperatures is likely to be the primary driver of arthropod proliferation, although they are also sensitive to changes in humidity, carbon dioxide levels, and water levels. As regions warm, arthropods will be able to survive where they were not able to previously, potentially infecting more individuals. The incidence of several vector-borne diseases in the United States is predicted to increase in multiple states as climate change progresses. The World Health Organization predicts that in North America, Dengue Hemorrhagic Fever and Lyme disease will become the primary vector-borne diseases that are increasingly common (Githeko, et. al, 2000).

Climate change has necessitated the transition from non-renewable energy sources such as coal, oil, and natural gas to renewable, low-carbon energy sources such as solar, wind, and hydroelectric. These energy sources, although much better equipped to reduce carbon-induced climate change, require materials that pollute the environment when mined and can release toxic waste during processing and disposal. Critical minerals are used in low-carbon renewable energy, and they are subject to both the environmental issues that accompany regular mineral extraction as well as issues related to scarcity from geopolitical issues, trade policy, and geological rarity. Tellurium is a critical mineral produced primarily as a byproduct of copper and used in cadmium-telluride (CdTe) solar panels. As these solar panels become more common, the problems that arise with many critical minerals’ usage (pollution, unfair distribution, human health complications) become more apparent. Looking at these issues through an energy justice framework can help to ensure availability, sustainability, inter/intragenerational equity, and accountability, and this framework can provide a more nuanced understanding of the costs and the benefits that will accrue with the transition to low-carbon, renewable energy. Energy justice issues surrounding the extraction of critical minerals will become increasingly prevalent as more countries pledge to have a zero-carbon future.

Climate change is a well-known global threat to societal systems; however, its effects on the health of individuals are often less evident. Physicians who aim to properly treat patients holistically must be educated on the various forms of illness and disease projected to be exacerbated by climate change. Without this necessary climate education, physicians run the risk of being unable to fulfill the most sacred charge of the Hippocratic oath: Do No Harm. To ensure that physicians moving forward are prepared to face this new global health threat, the prevalence of climate change in current medical school curricula must be examined. Content analysis of publicly available medical school curricula in the Southwest U.S. was done using ChatGPT to track the frequency of climate health search terms. Medical school curricula analyzed included mandatory degree programs as well as optional dual degree programs or pathways for medical student education. Researchers found that medical schools within the Southwest region of the United States are not sufficiently preparing students to mitigate the regional effects of climate change on the health of patients. Mandatory medical degree curriculum does not sufficiently educate on climate health issues, nor is it present in Utah, New Mexico, or Colorado. Optional degrees and pathways are available to medical students to enroll in and may be sufficient to educate a medical student, but are not enticing enough to sufficiently educate all medical students. Some medical schools have recently conducted revisals of their mandatory curriculum and still show a lack of education available about climate health issues. The lack of educational resources for future providers could lead to detrimental health outcomes for patients, and medical schools in development should take the lead in educating their students about climate health issues.
