Evaluating the Time of Emergence of Heat Waves using Different Definitions
Heat extremes, such as heat waves, are characterized by human health effects, increased mortality, and ecosystem-wide impacts. Previous studies of heat waves do not define when and where heat wave frequency will be distinguishable from the background frequency of heat waves in the coming century, …

Managing impacts of hydrological droughts and heat waves on thermal power plants
… and electricity grids. Recent droughts and heat waves have highlighted the tension between thermal power plants and water resources, stimulating various research efforts. Prior research work has largely focused on long term energy infrastructure choices to ameliorate the identified tensions. …

Evolution at the edge: how hibernation, heat waves, and hybridization impact a range expansion
Evolutionary processes shape the diversity of life on earth. Over millennia, species diverge from one another, radiating out into the tree of life. The same processes of evolution are also acting in much shorter periods of time, selecting for traits, mixing genes across populations, and generating …

Heat Waves, Early Birth, and Vulnerable Populations: Epidemiological and Spatial Analyses in the United States
Heat waves are a serious and growing threat to human health and society. While there is no single definition of a heat wave, elevated morbidity and mortality during extreme heat is consistently observed in addition to other societal impacts, such as strain on the energy infrastructure, drought, and …

Population health and climate change: public perceptions, attitudes and adaptation to heat waves in Adelaide, Australia
… climate change will increase the frequency of heat waves which have an impact on population health. In Adelaide, unprecedented heat waves have been experienced in recent years which had significant impact on human health. The objectives of this research project were to: (1) explore public …

Mitigating Peak Load and Heat Stress under Heat Waves by Scheduling Cooling and Energy Storage Systems
As the climate changes, heat waves are becoming more frequent and severe. Exposure to heat waves could lead to heat stress. Heat waves intensify cooling demand and reduce air conditioner efficiencies. It causes peaks in electricity demand that pose operational challenges to the power grid. This …

Impacts of heat waves on food quantity and quality of soy bean/corn in the Midwest at ambient and elevated [CO2]
Heat waves have significant impacts on managed and unmanaged plant productivity. Yet, current studies of the effects of heat waves on crops are confined to post-mortem and historical analyses. There are no field based heat wave studies on major crops. In the past decade, the development of …

Prioritizing Preparedness: Extreme Heat and Climate Change Preparation of Midwestern Health Departments
… dissertation is about the factors that influence heat wave preparedness of Midwestern health departments, and the climate change perceptions of public health officials. Heat waves have historically impacted the Midwest and, due to the variable pattern of these events, are full of uncertainties. …

Vulnerability analysis and new tools for climate change adaptation of marine and lagoon systems
… (CC), particularly sea warming, and marine heat waves (MHWs), are affecting coastal marine ecosystems around the world on different hierarchical levels of ecosystem organization. In this context, the Mediterranean Sea can be considered an "open-air laboratory", as it is universally …

Comparative studies on Macrocystis pyrifera and Ecklonia maxima (Laminariales) in South Africa; investigating the use of M. pyrifera as abalone feed in South African aquaculture and assessing the vulnerability of these two species to Marine Heat Waves
… climatic events such as storms and Marine Heat Waves (MHW’s). The second study investigated the impact of MHW’s on both M. pyrifera and E. maxima recruits. Recruits of both species were exposed to an experimentally simulated MHW for a 72 hour period. Recruits were subjected to four …

Effects of Air vs. Air+Soil Heating During a Simulated Heat Wave on White Oak (Quercus alba) and Black Oak (Quercus velutina)
… shifts in climate. One type of event, the summer heat wave, may already be increasing in some areas of the world. Large-scale reductions in Net Primary Productivity and mortality have been reported during heat waves in forested ecosystems. Unfortunately, our understanding of how abrupt heat-stress …

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, …

Seeing the city for the trees : public space, climate adaptation, and environmental justice in LA and New York's "Million Trees" campaigns
Urban heat waves are becoming more frequent and severe as climate change magnifies the "urban heat island" effect. While trees significantly reduce ambient temperatures through shading and evapotranspiration, their effect is highly localized. Consequently, more people die from heat waves in …
