Press Spin: House Committee briefing on global warming – Nov 14

A Democrat briefing by the House Committee on Natural Resources on global warming was just a show…..no alternative points of view allowed…..no hard questions asked of those presenting their claims.  Click here to view the briefing.

Of course, the press picked it up and reported it as the only acceptable point of new……this type of partisan pandering is very much part of the problem with the entire climate discussion…..

This news article is a joke. The problems with the work of these researchers has been well covered by others……

Press Spin: Waters of the US definition clarity will destroy Clean Water Act?

Here’s an alarmist article using the drinking water hammer to argue against resolution of the definition of the Clean Water Act jurisdictional problem….the current approach by USEPA is such an overreach, congress must address the issue in some way to bring clarity to an otherwise out of control situation….Of course, this article only tells one side of the story…..click here.

Peters et al 2011: Understanding the link between environmental exposures and health: does the exposome promise too much?

Is there a physical basis for the “exposome”? If not, then this is mythology.

A. Peters, G. Hoek, and K. Katsouyanni. Understanding the link between environmental exposures and health: does the exposome promise too much? Journal of Epidemiology and Community Health. 2011 Nov 11.

Environmental exposures affecting human health range from complex mixtures, such as environmental tobacco smoke, ambient particulate matter air pollution and chlorination by products in drinking water, to hazardous chemicals, such as lead, and polycyclic aromatic hydrocarbons, such as benz(a)pyrene. The exposome has been proposed to complement the genome and be the totality of all environmental exposures of an individual over his or her lifetime. However, if measurements of the exposome in biological samples are the sole tool for exposure assessment there are a number of limitations. First, it has limited utility for fully capturing the impact of complex mixtures such environmental tobacco smoke or particulate matter air pollution. Second, a number of relevant environmental exposures such as noise, heat or electromagnetic fields do not have direct correlates as metabolites or protein adducts, but there is important evidence linking them with health effects. Third, functional genomic changes are likely in many instances to be both a susceptibility factor and a marker of internal doses in response to environmental exposures. Fourth, internal dose measurements of environmental exposures might have lost the distinct signature of the relevant sources. This paper emphasises the obligation of environmental epidemiology to provide robust evidence to assist timely and sufficient protection of vulnerable subgroups of populations from environmental hazards. Therefore, in applying the exposome concept to environmental health problems, a strong link with the external environment needs to be maintained.

Fang et al: Global warming, human-induced carbon emissions, and their uncertainties

J.Y. Fang, J.L. Zhu, S.P. Wang, C. Yue, H.H. Shen. Global warming, human-induced carbon emissions, and their uncertainties. Science China Earth Sciences, October 2011 Vol.54 No.10: 1458–1468. doi: 10.1007/s11430-011-4292-0

Abstract: In recent decades, there have been a number of debates on climate warming and its driving forces. Based on an extensive literature review, we suggest that (1) climate warming occurs with great uncertainty in the magnitude of the temperature increase; (2) both human activities and natural forces contribute to climate change, but their relative contributions are difficult to quantify; and (3) the dominant role of the increase in the atmospheric concentration of greenhouse gases (including CO2) in the global warming claimed by the Intergovernmental Panel on Climate Change (IPCC) is questioned by the scientific communities because of large uncertainties in the mechanisms of natural factors and anthropogenic activities and in the sources of the increased atmospheric CO2 concentration. More efforts should be made in order to clarify these uncertainties.

Access to safe water still a problem for many people

Sierra Leone is just one of many areas  of the world where access to safe water is a problem. Click here for more….

Atieli et al 2011: Assessment of water storage, treatment and use in the semi arid Kimana area, Oloitokitok district, Kenya.

H. Atieli, J.H. Magara, S. Bibi, K. Huber, A. Riner, M. Steeves, and A. Whilhelm. Assessment of water storage, treatment and use in the semi arid Kimana area, Oloitokitok district, Kenya. East Afr J Public Health. 2010 Dec;7(4):331-7.

Moi University, P.O Box 4606, Eldoret, Kenya.

Objectives: This study sought to identify the methods and associations of water storage, treatment and use among residents in the Kimana Fenced Area, Oloitokitok, Kenya for comparison with current best practices in order to develop recommendations to improve water sanitation issues in this area.

Methods: In a cross-sectional study design, 330 households were randomly selected and interviewed on water storage, treatment, and use practices.

Results: Eighty two percent of observed containers met CDC guidelines for improved water storage containers. Fifty seven percent of survey respondents reported not treating their drinking water, of which 49% indicated that they believed the water was already clean. Logistic regression showed that people who believed their water was unsafe were twice more likely to treat their water than those who perceived their water to be somewhat safe (p = 0.058). Those living outside the furrows were 56% less likely to treat their water in the home compared to those living along the furrow (p = 0.023). Respondents with a pastoral lifestyle were 69% less likely to treat their water than those with a non-pastoral lifestyle (p = .009). In terms of tribe, the largest treatment disparity was noted amongst the Maasai, with only 37.7% reporting any form of treatment.

Conclusion: Tribe, pastoral lifestyle, proximity to the furrow and socio-economic status were found to contribute to water storage method and treatment within the Kimana fence. It is critical that these factors be addressed in future water storage and treatment interventions in this area.
