A combustion model which captures the interactions among nonlinear convection, chemical reaction and radiative heat transfer is studied. New phenomena are found with radiative heat transfer present. In particular, there is a weak detonation solution for each radiative heat loss coeecient. The speed of the weak detonation wave decreases as the heat loss coeecient increases and the detonation wav...

OBJECTIVES The objective of this paper is to describe Montreal's heat response plan and its application during the July 2010 heat wave. PARTICIPANTS AND SETTING The Montreal heat response plan is designed to ensure the surveillance of weather and health indicators during the summer season and to coordinate actions to be undertaken during this period to reduce morbidity and mortality due to he...

BACKGROUND From January 30-February 6, 2011, New South Wales was affected by an exceptional heat wave, which broke numerous records. Near real-time Emergency Department (ED) and ambulance surveillance allowed rapid detection of an increase in the number of heat-related ED visits and ambulance calls during this period. The purpose of this study was to quantify the excess heat-related and all-cau...

BACKGROUND Climate models project that heat waves will increase in frequency and severity. Despite many studies of mortality from heat waves, few studies have examined morbidity. OBJECTIVES In this study we investigated whether any age or race/ethnicity groups experienced increased hospitalizations and emergency department (ED) visits overall or for selected illnesses during the 2006 Californ...

Climate change and human health are intertwined. The heat waves in Chicago, in 1995, and in Paris, in 2003, followed by Hurricane Katrina_s destruction of New Orleans, raised awareness of the risks faced by vulnerable older people. Many cities have responded by announcing emergency preparedness plans; some of these plans have already been tested. Last summer, from July 27 to August 5, New York ...

Index words: Climate change Extreme heat Chicago Heat waves Health impacts Mortality Over the coming century, climate change is projected to increase both mean and extreme temperatures as heat waves become more frequent, intense, and long-lived. The city of Chicago has already experienced a number of severe heat waves, with a 1995 event estimated to be responsible for nearly 800 deaths. Here, f...

Heat-wave risk in cities is determined both by regional climate evolutions and by cities size and shape change, because they can impact heat island effect. Land planning and urban transport policies, due to their long-lasting impact on cities shape, can therefore play a role in heat-wave risk mitigation. However, the link between these policies and resulting change in urban heat island is far f...

BACKGROUND Devastating health effects from recent heat waves in China have highlighted the importance of understanding health consequences from extreme heat stress. Despite the increasing mortality from extreme heat, very limited studies have quantified the effects of summer extreme temperature on heat-related illnesses in China. METHODS The associations between extreme heat and daily heat-re...
