John R. Christy: Climate science claims are “unprovable”

“Why do we argue about climate change?

The reason there is so much contention regarding “global warming” is relatively simple to understand: In climate change science we basically cannot prove anything about how the climate will change as a result of adding extra greenhouse gases to the atmosphere.

So we are left to argue about unprovable claims.”

NASA looking for something to do, takes on pure Democrat political focus

I believe historians have been looking at this issue for a very long time. Why would NASA? Because they are now part of the Democrat party. These people believe they can predict the future. Thinking they are wise, they have become fools.

“Few think Western civilization is on the brink of collapse—but it’s also doubtful the Romans and Mesopotamians saw their own demise coming either.

If we’re to avoid their fate, we’ll need policies to reduce economic inequality and preserve natural resources, according to a NASA-funded study that looked at the collapses of previous societies.” click here

A new prediction from Michael E. Mann

From the Hockey Schtick:

“Fraudster Michael Mann has published an article in Scientific American today entitled “Why Global Warming Will Cross a Dangerous Threshold in 2036,” subtitled, “Emitting carbon dioxide at current rates will soon push Earth’s temperature up by 2 degrees Celsius. Here’s how to make the calculation yourself.” click here for the full commentary and Mann’s article.

I would place the publication Dr. Mann chose for his prediction, Scientific American, in darkest of the grey literature.

Brush your teeth

JP Pessan, MM Manarelli, KY Kondo, FM de Italiani, CA Kobayashi, GM Whitford, MA Buzalaf. Plaque fluoride concentrations associated to the use of conventional and low-fluoride dentifrices. Am J Dent. 2013 Dec;26(6):347-50.

PURPOSE: This double-blind, crossover study evaluated whole plaque fluoride concentration (F), as well as whole plaque calcium concentrations (Ca) after brushing with a placebo (PD – fluoride free), low-fluoride (LFD, 513 microg F/g) and conventional (CD, 1,072 microg F/g) dentifrices.

METHODS: Children (n=20) were randomly assigned to brush twice daily with one of the dentifrices, during 7 days. On the 7th day, samples were collected at 1 and 12 hours after brushing. F and Ca were analyzed with an ion-selective electrode and with the Arsenazo III method, respectively. Data were analyzed by ANOVA, Tukey’s test and by Pearson correlation coefficient (P<0.05).

RESULTS: The use of the fluoridated dentifrices significantly increased plaque [F]s 1 hour after brushing when compared to PD, returning to baseline levels 12 hours after. Positive and significant correlations were found between plaque [F] and (Ca) under most of the conditions evaluated. The mean increase in plaque [F] observed 1 hour after brushing with the CD were only about 47% higher than those obtained for the LFD. The use of a LFD promotes proportionally higher increases in plaque [F] when compared to a CD. Plaque F concentrations were also shown to be dependent on plaque Ca concentrations.

Lack of exposure data a fatal flaw in drinking water fluoride studies

This type of retrospective study is usually cited to prop up the addition of fluoride in drinking water. Unfortunately, the limitations of the study are such that it cannot draw any conclusions at all about whether addition of fluoride is beneficial. No actual fluoride exposure measurements were considered and these are typically not available. So the authors simply assume their way to a forgone conclusion that addition of fluoride is good, while intentionally ignoring any other potential harmful affects in this population.

IA Jolaoso, J Kumar, ME Moss. Does fluoride in drinking water delay tooth eruption? J Public Health Dent. 2014 Mar 17. doi: 10.1111/jphd.12053.

OBJECTIVES: The objectives of this study are to determine the effect of fluoride exposure on permanent tooth eruption patterns as well as to understand its effect on caries attack rate by accounting for the number of erupted tooth surfaces.

METHODS: We analyzed data from the 1986-1987 National Survey of Oral Health of US Schoolchildren to determine the mean number of erupted permanent teeth and permanent first molars according to fluoride level in drinking water. The analysis included 13,348 children aged 5-17 years with a history of single residence. We also estimated the attack rate (decayed, missing, and filled surfaces/surfaces at risk) for fluoride deficient, suboptimal, and optimally fluoridated areas adjusting for covariates. Multivariable statistical analyses were performed to control for potential confounders.

RESULTS: By age 7, almost all permanent first molars had erupted. The adjusted mean number of erupted permanent first molars per child were 3.81, 3.67, and 3.92 in areas with <0.3, 0.3-<0.7, and 0.7-1.2 ppm of fluoride, respectively. The adjusted caries attack rate in the first permanent molars among 5- to 17-year-old children was 93, 81, and 78 per 1,000 surfaces in fluoride deficient, suboptimal, and optimally fluoridated areas, respectively (P < 0.0001). This pattern of higher first molar attack rate among children in the fluoride-deficient communities was also observed in all erupted teeth.

CONCLUSION: Exposure to fluoride in drinking water did not delay the eruption of permanent teeth. The observed difference in dental caries experience among children exposed to different fluoride levels could not be explained by the timing of eruption of permanent teeth.
