New studies point to less intense, less frequent storms due to global warming

“The studies fly in the face of a recent Nature editorial piece, one filled with the usual worn out alarmist propaganda language of climate doom we’ve been seeing for over a quarter century. The editorial claims some scientists have already found the link between “weird weather” and greenhouse gases.” click here

Iodo-Trihalomethanes in Canadian Drinking Water

Tugulea AM, Aranda-Rodriguez R, Bérubé D, Giddings M, Lemieux F, Hnatiw J, Dabeka L, Breton F. The influence of precursors and treatment process on the formation of Iodo-THMs in Canadian drinking water. Water Res. 2017 Nov 27;130:215-223. doi: 10.1016/j.watres.2017.11.055.

The National Survey of Disinfection By-Products and Selected Emerging Contaminants investigated the formation of various disinfection by-products and contaminants in 65 water treatment systems (WTSs) across Canada. Results for six iodo-trihalomethanes (iodo-THMs) are reported in this paper. The participating water treatment systems included large, medium and small systems using water sources and treatment processes which were representative of Canadian drinking water. Five water samples (source water, treated water and three water samples along the distribution system) were collected from each treatment system, both under winter and summer conditions. Samples were stabilized, shipped cold and analysed for six iodo-THMs (dichloroiodomethane-DCIM; dibromoiodomethane-DBIM; bromochloroiodomethane-BCIM; chlorodiiodomethane-CDIM; bromodiiodomethane-BDIM and triiodomethane or iodoform-TIM), using a SPME-GC-ECD method developed in our laboratory (MDLs from 0.02 μg/L for iodoform to 0.06 μg/L for bromodiiodomethane). Concentrations of relevant precursors like dissolved organic carbon (DOC), bromide, iodide and total iodine, as well as other water quality parameters, were also determined. Detailed information about the treatment process used at each location was recorded using a questionnaire. The survey showed that one or more iodo-THMs were detected at 31 out of 64 water treatment systems (WTSs) under winter conditions and in 46 out of 64 WTSs under summer conditions (analytical results from one site were excluded due to sampling challenges). Total iodo-THM concentrations measured during this survey ranged from 0.02 μg/L to 21.66 μg/L. The highest total iodo-THM concentration was measured in WTS 63 where all six iodo-THMs were detected and iodoform was present in the highest concentration. The highest iodo-THM formation was found to occur in treatment systems where water sources had naturally occurring ammonium as well as high bromide, high iodide and/or total iodine concentrations. In two such water systems the total concentration of iodo-THMs exceeded the concentration of regulated THMs.

The “global warming” slow-down is reality

“This article will use the GISTEMP global temperature series, to investigate whether the slowdown is real. I know that some people will throw up their hands in horror, at the thought of using the GISTEMP temperature series. I have deliberately used GISTEMP, because it has a reputation as a heavily adjusted, warmist friendly, temperature series. If I can show strong evidence for a recent slowdown in GISTEMP, then the recent slowdown can not be denied.” click here

Chicago Climate Charter misguided, political posturing

This sort of effort is not based on the best available science but is simply political posturing. Such politically motivated efforts undermine efforts to solve real-world problems resulting from changes in climate.

“Ten more cities have signed on to the Chicago Climate Charter, a now 67-city pact to fight climate change in the face of President Trump’s decision to pull the U.S. out of the Paris climate agreement.” click here

AR-15 Rifle an American Standard

“The rifle grew in popularity, going from a cult following in early civilian production to the widespread, near-familial loyalty the rifle inspires today. This change occurred as the rifle went from being made by a handful of manufacturers in the 1980s to being made by nearly every major gun manufacturer in the 21st century. And the love for the AR-15 is not limited to older generations. On November 20, 2017, Breitbart News reported that millennials offer the most opposition to the Democrat push for an “assault weapons” ban.” click here

Is Trace Lithium in Tap Water Beneficial?

Small associations from ecological studies are questionable whether the effect is negative or as in this case positive.

Fajardo VA, LeBlanc PJ, Fajardo VA. Trace lithium in Texas tap water is negatively associated with all-cause mortality and premature death. Applied physiology, nutrition, and metabolism 2017 Dec 5. doi: 10.1139/apnm-2017-0653.

Lithium in tap water was previously found to have life-extending effects across 18 Japanese municipalities. Using a larger dataset with several Texas counties, our study shows that lithium concentrations in tap water are negatively associated with all-cause mortality (r = -0.18, p = 0.006, 232 counties) and years of potential life lost (r = -0.22, p = 0.001, 214 counties). Thus, our present findings extend and reinforce lithium’s purported life-prolonging effect in humans.

Providing Safe Drinking Water to Slum Households, Siliguri, West Bengal, India

Bhar D, Bhattacherjee S, Mukherjee A, Sarkar TK, Dasgupta S. Utilization of safe drinking water and sanitary facilities in slum households of Siliguri, West Bengal. Indian J Public Health. 2017 Oct-Dec;61(4):248-253. doi: 10.4103/ijph.IJPH_345_16.

BACKGROUND: With the rapid expansion of urban population, provision of safe water and basic sanitation is becoming a challenge; especially in slums. This is adversely affecting the health of the people living in such areas.

OBJECTIVES: The study was conducted to measure the proportion of households using improved drinking water and sanitation facilities and to determine the association between diarrhea in under-five children with water and sanitation facilities.

METHODS: A community-based, cross-sectional study was conducted among 796 slum households in Siliguri from January to March 2016 by interviewing one member from each household using a predesigned and pretested questionnaire based on the WHO/UNICEF Joint Monitoring Program Core questions on drinking water and sanitation for household surveys.

RESULTS: A majority 733 (92.1%) of slum households used an improved drinking water source; 565 (71%) used public tap. About two-thirds (65.7%) household used improved sanitation facilities. About 15.8% households had reported diarrheal events in children in the previous month. Unimproved drinking water sources (AOR = 4.13; 1.91, 8.96), houses without piped water supply (AOR = 4.43; 1.31, 15.00), and latrines located outside houses (AOR = 3.61; 1.44, 9.07) were significantly associated with the diarrheal events in children.

CONCLUSION: The utilization of improved drinking water source was high but piped water connection and improved sanitary toilet used was low. Association between diarrheal events and type of drinking water sources and place of sanitation might suggest fecal contamination of water sources. Awareness generation through family-centered educational programs could improve the situation.
