“…In a study involving 13 Spanish cities, Iniguez et al found that populations in cities with higher variability in temperature showed greater resistance to heat effects (25). In our study, the range of temperatures was 42.2℃ and 23℃ in Beijing and Brisbane, respectively.…”

The interactive effect between temperature and ambient particulate matter on mortality has attracted attention world-wide, but the results of studies investigating this interaction have been inconsistent. This comparative study aims to further clarify this important public health issue. The present study used two separate time-series analyses to explore whether the mean temperature modified the impact of ambient particulate matter of less than 10 µm in diameter (PM10) on daily non-accidental mortality in Beijing, China (2005China ( -2009 and Brisbane, Australia (2004-2007. A bivariate response model and a stratification parametric model were used. The results show statistically significant interactive effects between PM10 and temperature on non-accidental mortality at various time lags. PM10 had a greater adverse effect on non-accidental mortality from cardiovascular disease on high temperature days. The interactive term coefficients per interquartile range increase in PM10 concentration and in high temperature levels were 1.95% (0.08%, 3.83%) in Brisbane, Australia on the current day and 0.25% (0.05%, 0.45%) in Beijing, China 2 days before the current day. The implications of this result indicate that it is important to reduce the emission of air particles on high temperature days in both cities, especially in Brisbane, Australia.

“…As shown in Fig. 6 (Knowlton et al 2009;Kunzli et al 2006;Iñiguez et al 2010). A recent analysis of temperatures during summers with no heat waves (1999)(2000)(2001)(2002)(2003) found a 3% increase in deaths in any given day for a 10°F (5.6°C) increase in temperature (including humidity) (Basu et al 2008).…”

“…A recent analysis of temperatures during summers with no heat waves (1999)(2000)(2001)(2002)(2003) found a 3% increase in deaths in any given day for a 10°F (5.6°C) increase in temperature (including humidity) (Basu et al 2008). Factors that should be considered when identifying community-level risk include the incidence of relatively high percentages of (1) children under 5 years of age and elderly people 65 and over; and (2) chronically ill persons (especially those suffering cardiovascular or respiratory conditions) (Knowlton et al 2009;Iñiguez et al 2010). As stated in the Introduction, in 2050, there will be one million seniors 65 years and older in the San Diego region, roughly equal to nearly one-quarter of the region's total population.…”

This paper explores what the San Diego region may look like in the year 2050 as projected changes in regional climate conditions take place. Focusing on interrelated issues of climate change, sea level rise, population growth, land use, and changes in water, energy, public health, wildfires, biodiversity, and habitat, the paper reviews the potential impacts of a changing climate by 2050 and makes recommendations for changes in planning processes at the local and regional levels to prepare for these impacts. The original research for this study was completed in 2008 by a team of 40 experts from the region including universities, nonprofit organizations, local governments, public sector agencies and private sector entities. This paper has now been updated with more recent research regarding climate change adaptation while preserving the integrity of the original research team's work. The simulated impacts discussed in this study are based on regional projections of climate change generated by scientists at Scripps Institution of Oceanography, employing three climate models and two emissions scenarios used by the Intergovernmental Panel on Climate Change. The impacts are discussed in the context of significant regional growth expected during the period as well as an aging population base. Key issues explored in the report include potential inundation of six selected low-lying coastal areas in San Diego due to sea level rise, potential shortfalls in water deliveries, peak energy demand increases due to higher temperatures, growing risk of devastating wildfires, migrations of species in response to higher temperatures in an increasingly fragmented natural habitat, and public health issues associated with extreme temperature events.

“…We also found that mean AT in Brisbane is higher than that in Beijing, which might partly explain the different threshold AT. In 13 Spanish cities, Iniguez et al also found that minimum mortality temperature rose as the mean temperature of the cities increased (24) . It is biologically plausible that temperatures can affect health outcomes.…”

This comparative study aimed to clarify the different characteristics of time course of apparent temperature and their effect on cardiovascular mortality in Beijing, China, and Brisbane, Australia. The present study used polynomial distributed lag models to explore the lagged effects of apparent temperature on daily cardiovascular mortality up to 27 days in Beijing, China (2005-2009), and Brisbane, Australia (2004. The results show a longer lagged effect on cold days and a shorter lagged effect on hot days. The cut-off points in Beijing and Brisbane were 22℃ and 27℃, respectively. In Beijing, a statistically significant association was observed for lags of 0-3 days and lags of 3-18 days on hot and cold days, respectively. In Brisbane, a significant association was found for lags of 3-4 days and lags of 10-21 days on hot and cold days, respectively. The lagged effects extended longer for cold apparent temperature but were immediate for hot apparent temperature. Though the cut-off point in Brisbane was higher than in Beijing, the population in Beijing was more resistant to high temperature above the cut-off point than the population in Brisbane.
