Heat-Related Mortality in a Warming Climate: Projections for 12 U.S. Cities
Heat is among the deadliest weather-related phenomena in the United States, and the number of heat-related deaths may increase under a changing climate, particularly in urban areas. Regional adaptation planning is unfortunately often limited by the lack of quantitative information on potential future health responses. This study presents an assessment of the future impacts of climate change on ...


Estimating the Costs and Benefits of Providing Free Public Transit Passes to Students in Los Angeles County: Lessons Learned in Applying a Health Lens to Decision-Making
In spite of increased focus by public health to engage and work with non-health sector partners to improve the health of the general as well as special populations, only a paucity of studies have described and disseminated emerging lessons and promising practices that can be used to undertake this work. This article describes the process used to conduct a Health Impact Assessment of a proposal ...
Act-based Versus Harm-based Sanctions for Environmental Offenders
We investigate the design of harm-based and act-based sanctions for environmental offences. Empirical evidence concerning both criminal and administrative sanctions for Belgium clearly shows that the determination of harm-based and act-based sanctions for environmental offences is less straightforward than theory predicts. In criminal cases, harm-based sanctions are influenced by offence-relate...


In vivo genotoxicity of estragole in male F344 rats
Estragole, a naturally occurring constituent of various herbs and spices, is a rodent liver carcinogen which requires bio-activation. To further understand the mechanisms underlying its carcinogenicity, genotoxicity was assessed in F344 rats using the comet, micronucleus (MN), and DNA adduct assays together with histopathological analysis. Oxidative damage was measured using human 8-oxoguanine-...
S. Fred Singer and the Nongovernmental International Panel on Climate Change
Among the many highlights of his distinguished career, one of the great scientific contributions of S. Fred Singer is his work with the Nongovernmental International Panel on Climate Change (NIPCC). Formed by Dr. Singer in the early 2000s, this organization of scientists has emerged as one of the leading institutions challenging the contentions that are made in the periodic United Nations repor...


Climate Models and Their Simulation of Precipitation
Current state-of-the-art General Circulation Models (GCMs) do not simulate precipitation well because they do not include the full range of precipitation-forming mechanisms that occur in the real world. It is demonstrated here that the impact of these errors are not trivial - an error of only 1 mm in simulating liquid rainfall is equivalent to the energy required to heat the entire troposphere ...
Political Science
Ipcc (2013) replaces climate models' over-predictions of near-term global warming with its "expert assessment" that warming in the next 30 years may scarcely exceed that of the last 30. Medium-term anthropogenic forcings and global temperature projections have been all but halved since 1990. There has been no global warming this millennium. Nevertheless, at the intergovernmental level, an aprio...

Systematic and Logical Problems in Global Warming Science
Arguments put forth in favor of anthropogenic global warming (AGW) are frequently lacking in objectivity due to the use of imprecise terms and unwarranted extrapolations. A salient characteristic of such arguments is, moreover, the seemingly arbitrary attribution of causes to certain phenomena [Singer, 2012a]. As a result, such arguments run counter to the reasoning that is a hallmark of the sc...
Molecular analysis of bacterial diversity in mudflats along the salinity gradient of an acidified tropical Bornean estuary (South East Asia)
The Brunei River and Bay estuarine system (BES) in the northwest of Borneo is acidic and highly turbid. The system supports extensive intertidal mudflats and presents a potentially steep salinity and pH gradient along its length (45 km). Temporal variation in physical parameters is observed diurnally due to seawater flux during tidal forcing, and stochastically due to elevated freshwater inflow...

Impact of an asbestos cement factory on mesothelioma incidence: Global assessment of effects of occupational, familial, and environmental exposure
Few studies have examined the incidence of malignant mesothelioma (MM) associated with distinct sources of asbestos exposure (occupational, familial, or environmental). We assessed the impact of asbestos exposure—global and by source—on the incidence of MM in Broni, an Italian town in which an asbestos cement factory once operated (1932–1993). Based on data collected by the Lombardy Mesot...
Theoretically exploring direct and indirect chemical effects across ecological and exposure scenarios using mechanistic fate and effects modelling
Predicting ecosystem response to chemicals is a complex problem in ecotoxicology and a challenge for risk assessors. The variables potentially influencing chemical fate and exposure define the exposure scenario while the variables determining effects at the ecosystem level define the ecological scenario. In absence of any empirical data, the objective of this paper is to present simulations by ...

Applicability of a noise-based model to estimate in-traffic exposure to black carbon and particle number concentrations in different cultures
Several studies show that a significant portion of daily air pollution exposure, in particular black carbon (BC), occurs during transport. In a previous work, a model for the in-traffic exposure of bicyclists to BC was proposed based on spectral evaluation of mobile noise measurements and validated with BC measurements in Ghent, Belgium. In this paper, applicability of this model in a different...
A randomized trial to evaluate primary care clinician training to use the Teachable Moment Communication Process for smoking cessation counseling
To implement and evaluate the impact of a Teachable Moment Communication Process (TMCP) training intervention on clinicians’ smoking cessation counseling behaviors in practice. Using a group randomized trial, 31 community-based, primary care clinicians in Northeast Ohio received either TMCP training or an attention control (2010-2012). TMCP training consisted of two, three-hour sessions invol...
Similar concentration of surfactants in rural and urban areas
Since surfactants are used in various products, they end up in surface and wastewater. Surfactants may therefore impact ecosystems and living organisms. Actually, only few anionic surfactants and some alkylphenols are regulated. There is no comprehensive evaluation of surfactants in the atmosphere, surfaces and waters of areas of increasing anthropic levels. Here, we measured the levels of cati...
Deconstructing and unpacking scientific controversies in intensification and sustainability: why the tensions in concepts and values?
Assuming ‘ceteris paribus’ in terms of the viability of the planet during the coming half-century or so, the rising needs of a burgeoning, but also increasingly rich and demanding world population will drastically change agriculture. Crop yields and animal productivity will have to increase substantially, with the risk of further depleting the resource base and degrading the environment, ma...
