article imageTop ten global cities at risk from power outages

New York - A new study from Johns Hopkins University has selected the ten major cities from across the U.S. most at risk from future power outages. The research implies that residents in these cities need to get used to periods of darkness.
For the research Johns Hopkins scientists developed a computer model to predict the increasing vulnerability of power grids in major coastal cities during hurricanes. With these they factored in historic hurricane information with various likely scenarios for future storm behavior. Using the model the team were able to pinpoint which of 27 cities, from Texas to Maine, will become more susceptible to blackouts from future hurricanes.
The cities most at risk are:
1. New York, NY
2. Philadelphia, PA
3. Jacksonville, FL
4. Virginia Beach, VA
5. Hartford, CT
6. Orlando, FL
7. Tampa, FL
8. Providence, RI
9. Miami, FL
10. New Orleans, LA
The rate of hurricanes is expected to increase through climate change. Although hurricanes, typhoons, and cyclones have always ravaged coasts, some scientists (although not all) are of the opinion that global warming may be making matters worse. This is because sea levels are rising and will continue to rise as oceans warm and glaciers melt. Rising sea level consequently means higher storm surges, even from relatively minor storms, which increases coastal flooding and subsequent storm damage along coasts.
The cities that feature in the list appear because of the anticipated impact on the Gulf and Atlantic coasts. In an example of the analysis, the researchers predict a 30 percent increase in the number of customers without power in Miami and New Orleans.
The idea behind the study is to enable the highlighted metropolitan areas to better plan for climate change. The new study has been published in the journal the journal Climatic Change. It is titled "Simulation of tropical cyclone impacts to the U.S. power system under climate change scenarios."
