Environmental extremist group shoots nuclear-engineering executive, attack scientists

And the response?   “These people don’t represent mainstream opinion.” How pathetic….

These people are killers…..until the credibility of science can be restored…..and environmental issues not used as a phoney front to push radical social changes and total governmental control…..expect more of this…..

Navy facility in Germany exceeds bromate MCL

An interesting report of bromate MCL exceedance at a Naval facility in Heidelberg (Germany)……bromate levels detected in tap water from 52 and 170 micrograms per liter (ug/L)…..the USEPA bromate MCL = 10 ug/L

Cause of bromate is not reported…..if ozone is used, it may be high bromide in the ground water source……if hypochlorite is used, then it is likely formed in the hypochlorite solution….

Fluoride addition to drinking water not necessary for dental health

Miller FY, Campus G, Giuliana G, Piscopo MR, Pizzo G. Topical Fluoride for Preventing Dental Caries in Children and Adolescents. Curr Pharm Des. 2012 May 25.

Abstract: The use of topically applied fluoride has been widely researched as a means to reduce the risk of dental caries in conjunction with other treatment modalities (mechanical oral hygiene, dietary control, antimicrobial intervention, pit and fissure sealants). There is overwhelming evidence that reports not only the significance and importance of the use of fluoride as a caries-preventive agent, but also how safe fluoride application is when used appropriately, particularly in higher risk individuals and populations. This paper reviews the caries-protective benefits of topical fluoride application in children and adolescents, with an emphasis on the clinical efficacy and safety of the vehicles by which fluoride is topically delivered. Fluoride toothpaste represents today the most cost-effective fluoride-delivery system in the oral cavity and its use should be the centerpiece in all caries-preventive strategies. On the other hand, mouthrinses, gels and varnishes currently represent adjuncts to toothpaste use and should be targeted towards individuals and groups at high risk of caries.

Greenland glacier retreat as drastic in 1930s as today

Analysis of historical images reveals that over the past decade, glacier retreat was as vigorous as in a similar period of warming in the 1930s…..not related to CO2 increase….

Anders A. Bjørk, Kurt H. Kjær, Niels J. Korsgaard, Shfaqat A. Khan, Kristian K. Kjeldsen, Camilla S. Andresen, Jason E. Box, Nicolaj K. Larsen and Svend Funder. An aerial view of 80 years of climate-related glacier fluctuations in southeast Greenland. Nature Geoscience, 5, 427–432 (2012) DOI: 10.1038/ngeo1481

Abstract: Widespread retreat of glaciers has been observed along the southeastern margin of Greenland. This retreat has been associated with increased air and ocean temperatures. However, most observations are from the satellite era; presatellite observations of Greenlandic glaciers are rare. Here we present a unique record that documents the frontal positions for 132 southeast Greenlandic glaciers from rediscovered historical aerial imagery beginning in the early 1930s. We combine the historical aerial images with both early and modern satellite imagery to extract frontal variations of marine- and land-terminating outlet glaciers, as well as local glaciers and ice caps, over the past 80 years. The images reveal a regional response to external forcing regardless of glacier type, terminal environment and size. Furthermore, the recent retreat was matched in its vigour during a period of warming in the 1930s with comparable increases in air temperature. We show that many land-terminating glaciers underwent a more rapid retreat in the 1930s than in the 2000s, whereas marine-terminating glaciers retreated more rapidly during the recent warming.
