TL;DR: Most of the temperature-related mortality burden was attributable to the contribution of cold, and the effect of days of extreme temperature was substantially less than that attributable to milder but non-optimum weather.

TL;DR: People have some ability to adapt to their local climate type, but both cold and hot temperatures are still associated with increased risk of mortality, and public health strategies to alleviate the impact of ambient temperatures are important.

TL;DR: In this article, a multivariate meta-analysis was used to pool the nonlinear and delayed effects of ambient temperature at the national level, in each country, and the estimated effects of cold and hot temperatures on mortality varied by community and country.

TL;DR: In this paper, the authors used positive matrix factorization (PMF) to identify sources of PM2.5 in a centrally located urban monitoring site in Seoul, Korea, every third day from 2003 to 2006 and analyzed for their chemical constituents.

TL;DR: One hundred ninetyfive chemically speciated samples were collected from March 2003 to February 2005 in the Seoul metropolitan area to investigate the characteristics of the major components in PM2.5 and to characterize the chemical variations between smog and non-smog events as discussed by the authors.
