Planetizen -"Coastal
neighborhoods in several Bay Area cities are likely to face such frequent
flooding from rising sea levels over the next century that residents will
simply pack up and leave, according to a new study of the effects of climate
change," reports Kurtis Alexander.
Those findings are from a report issued earlier this week by
the Union of Concerned Scientists [pdf], which is "the first nationwide
effort to identify the point at which coastal communities face the no-win
decision of having to flee or fight sea level rise."
The report assumes a "point of no return"—when
"at least 10 percent of a community experiences flooding 26 days a year,
or one day every two weeks," explains Alexander. "Already, more than
90 communities across the nation have hit a point of disruption that’s driving
people away […] Eighty more are expected to reach that threshold within 20
years if global warming continues at a moderate rate."
