Climate Changes Happen; They Cannot Be Denied, or Derailed

Like many other people today UN Secretary General Ban Ki-moon (here) seems to be very confused about changes in climate. Even the most brilliant scientist can fool themselves into believing that model projections are reality. They are not. Changes in climate happen.They cannot be denied or derailed. Climate is a dynamic system always in a state of changing and adjusting. 

Solar Energy Depends on Carbon-Based Fuels

The idea of eliminating carbon-based fuels is self-defeating. Without them solar energy will become even more unsustainable.

Rainwater as a Source of Drinking Water

 Shelly Rodrigo, Martha Sinclair, Andrew Forbes, David Cunliffe, and Karin Leder.  Drinking Rainwater: A Double-Blinded, Randomized Controlled Study of Water Treatment Filters and Gastroenteritis Incidence  American Journal of Public Health. 2011;101:842-847. doi:10.210B/AJPH.2009.185389)

Objectives. We examined whether drinking untreated rainwater, a practice that is on the rise in developed countries because of water shortages, contributes to community gastroenteritis incidence.

Methods. We conducted a double-blinded, randomized controlled trial in Adelaide, Australia. Sham or active water treatment units were installed, and participants recorded incidences of illness in a health diary for 12 months. The primary outcome was highly credible gastroenteritis (HCG; characterized by a specified number of loose stools or vomiting alone or in combination with abdominal pain or nausea in a 24-hour period), and we used generalized estimating equations to account for correlations between numbers of HCG events for individuals in the same family.

Results. Participants reported 769 episodes during the study (0.77 episodes/ person/year), with an HCG incidence rate ratio (active vs sham) of 1.05 (95% confidence interval [CI] = 0.82, 1.33). Blinding of the participants was effective (index = 0.65; 95% CI =0.58, 0.72).

Conclusions. Our results suggest that consumption of untreated rainwater does not contribute appreciably to community gastroenteritis. However, our findings may not be generalizable to susceptible and immunocompromised persons because these groups were specifically excluded from the study.
