Atmospheric carbon dioxide has nothing to do with flood events

Louisiana Flooding Not Related to Climate Change

“Is man-made global warming to blame for the heavy rainfall and flooding in Louisiana? Former Vice President Al Gore sure thinks so.” here

Philippine flooding takes toll, drinking water scarce

650+ deaths from flooding….drinking water plant damaged making potable water scarce….click here for more reporting.

 

 

Ghana (Africa) floods incorrectly attributed to “climate change”

Extreme weather events happen….and to attribute such events to an ambiguously defined “climate change” is misleading at best. The tragic impacts from these weather events in Northern Ghana (click here) are bad enough….but attributing them to the “climate change” god serves no useful purpose…..  

Milojevic et all 2011: Health Effects of Flooding in Rural Bangladesh

A. Milojevic, B. Armstrong, M. Hashizume, K. McAllister, A. Faruque, M. Yunus, P.K. Streatfield, K. Moji, and P. Wilkinson. Health Effects of Flooding in Rural Bangladesh. Epidemiology, 2011; Nov 11.

BACKGROUND: There is little information available on nontraumatic health risks as the result of floods, and on the factors that determine vulnerability to them (especially in low-income settings). We estimated the pattern of mortality, diarrhea, and acute respiratory infection following the 2004 floods in rural Bangladesh.

METHODS: We conducted controlled interrupted time-series analysis of adverse health outcomes, from 2001 to 2007, in a cohort of 211,000 residents of the Matlab region classified as flooded or nonflooded in 2004. Ratios of mortality, diarrhea, and acute respiratory infection rates in flooded compared with nonflooded areas were calculated by week for mortality and diarrhea, and by month for acute respiratory infection. We controlled for baseline differences as well as normal seasonal patterns in the flooded and nonflooded areas. Variations in flood-related health risks were examined by age, income level, drinking-water source, latrine type, and service area.

RESULTS: After fully controlling for pre-flood rate differences and for seasonality, there was no clear evidence of excesses in mortality or diarrhea risk during or after flooding. For acute respiratory infection, we found no evidence of excess risk during the flood itself but a moderate increase in risk during the 6 months after the flood (relative risk = 1.25 [95% confidence interval = 1.06-1.47]) and the subsequent 18 months.

CONCLUSIONS: We found little evidence of increased risk of diarrhea or mortality following the floods, but evidence of a moderate elevation in risk of acute respiratory infection during the 2 years after flooding. The discrepancies between our results and the apparent excesses for mortality and diarrhea reported in other situations, using less- controlled estimates, emphasize the importance of stringent confounder control.
