Fish Assemblage Structure Before and After a Marine Heatwave in West Hawai'i
Coral reefs are subject to marine heatwaves caused by human-induced climate change. Long-term thermal stress can negatively affect corals and the associated marine organisms that use these areas as critical habitat. In this study, we examined coral reef resilience to climate change by analyzing …

Viability of naturally ventilated buildings in the UK under predicted future summer climates
… of which already fail to perform under current heatwave conditions. This thesis addresses the summer performance of such buildings under current and future climates by means of building performance simulation. Current industry standard weather datasets for building performance simulation are not …

Extreme value modelling of heatwaves
… persist over many days. For example, the 2003 heatwave over Europe caused 40,000 deaths over a four week period at a cost of e 13.1 million to the agriculture sector. It is clear that accurate models for the risks associated with heatwaves are important to decision makers and planners who wish …

Investigating changes of summer urban heat island in Kansas City from 2000 to 2023 with remote sensing
… heat island may have issues when it comes to heatwave activity. Where heatwaves are showing higher urban values for temperatures, the rural surroundings are also showing temperatures high enough to bring down the value of urban heat island in both methods used to calculate urban heat island …

The physiological effects of heat stress on anthesis and pollination in domesticated sunflowers (Helianthus annuus L.)
… heated and unheated plants; and a natural heatwave. Sunflower insect visits were video imaged in all test conditions, and individual insects were counted. A variety of staining and imaging techniques were used to determine pollen fertility, style elongation, and stigma receptivity. Heating …

HOW HEATWAVES ARE CHANGING URBAN LIVABILITY ACROSS THE UNITED STATES: A CASE STUDY IN TEN COMMUNITIES
<p>Heatwaves are an important type of extreme climate event and directly result in more than 130 deaths and thousands of morbidities per year across the United States. Heat waves increase demands on water and energy, particularly in urban areas, because people use more water for drinking, …

From efficiency to sufficiency: Socio-technical analysis of the role of design, marketing, and users in shaping domestic comfort practices and Air Conditioning use in Jordan
… and how do these practices change during the heatwave? In order to understand architects’ practices and motivations in housing, and green design projects, the research first investigates how design decisions are negotiated between homeowners and architects, focusing on materiality and spatial …

Climate Adaptation in Out-Of-Hospital Settings: Building Strategic Disaster Resilience in Ambulance Operations
… of climate disasters, such as wildfires, floods, heatwaves, and other health emergencies, such as pandemics. Key findings indicate challenges in organizational resilience, with staffing shortages emerging as the most-cited risk identified by 88.3% of respondents, highlighting vulnerabilities. The …

Assessing factors contributing to the changes in historical temperature extremes and investigating future changes in extreme events
… changes in the properties of moderate and severe heatwave conditions are further analyzed. Comparisons of the projected temperature variables and future heatwaves among different climate models provide valuable information on the ability of the models in simulating the long-term variations of …

The ecological impacts of climate warming and pollution on freshwater microbial communities
… periods of warming (chapter one) and an acute heatwave event (chapter two). Our results suggest that microbial community responses to warming are predominantly driven by pre-exposure to urbanised contexts. Warmingwas found to only be a significant driver of community responses when it …

Birds of a Feather: Cultural and Ecological Relationships between the Unangax̂ and Seabirds in the Aleutian Islands, AK
… (Uria spp.) die-offs after the 2014-16 marine heatwave, my use of a novel compound-specific stable isotope application establishes ecological baselines that underscore their sensitivity to shifts in marine fish productivity. Taken together, this dissertation provides evidence that Subarctic …

Forest Isoprene Emissions: New Insights from a Novel Field Instrument
… higher temperatures and low rainfall in the 2018 heatwave and showed elevated isoprene levels. A new simple conceptual model is described, CamCan, which simulates isoprene concentration at different levels in the forest canopy. The model is used to calculate fluxes from the forest and an annual …

Coral reefs in the Anthropocene Ocean: novel insights from skeletal proxies of climate change, impacts, and resilience
… of these changes, including intensifying marine heatwaves (MHWs) and rapid ocean acidification (OA). Consequently, coral reefs are in broad-scale decline, threatening the livelihoods of hundreds of millions of people. Ensuring survival of coral reefs in the 21st century will thus require a new …

Assessing Natural Hazards and Climate Change in a Mountain Region with a Hydrological Digital Twin
… and vulnerabilities. A significant increase in heatwave risk of the region is revealed while cold wave risk declines except for large cities. This emphasizes the need for targeted adaptation strategies. To support hydrological hazard quantification, a Hydrological Digital Twin (HDT) is developed …

A Comparison of the Prediction Models for the Impact of Heat Wave on Total Mortality and Incidence of Heat-related Illness in the Republic of Korea
Heatwave surveillance systems of patients with heat-related illness generated by the Korea Centers for Disease Control and Prevention have been reported since 2010. So, there are few studies about relationship between incidence of heat-related illness and temperature during heat wave in Korea. This …
