In advance of President Obama's long-awaited speech on climate change, NPR looked at climate adaptation - preparing for the environmental changes it will cause. Rising sea level is the topic. In the U.S., two cities stand out: New York and Miami.
NPR host Jacki Lyden introduces the "cover story today: climate change and drowning cities, learning to live with rising seas." The 11-1/2 minute report is available as text, podcast and streaming audio.
Mayor Michael Bloomberg's "ambitious 20-year plan that includes seawalls....and flood control structures in the city streets" puts New York City in a class by itself in preparation, states Lyden's guest, science and nature writer Tim Folger. "But will it be enough?", he asks.
On the other extreme - not because it isn't preparing for sea level but because it may have the most to lose and the most difficult to defend, is Miami. Lyden states that "(i)f sea levels rise three feet (by mid-century) as is projected, the entire city of Miami will be uninhabitable". She asks Folger to explain why Miami will be so difficult to defend from rising sea level.
(T)he biggest challenge for Miami and all of Southern Florida, really, is that the sorts of solutions that work in New York and in the Netherlands and perhaps even in Ho Chi Minh City [which has a contract with the Dutch to try to protect that city from sea level rise, he explained earlier] won't work in Miami because Miami and most of Southern Florida rests on this foundation of really highly porous limestone. It's just like this honeycomb or like petrified Swiss cheese. It's extremely porous. And so building a barrier won't really work because the water will just continue to flow beneath that barrier.

- Lifting the Alton Road construction project six inches.
- Raising sea walls "on the western quarter of the island...and by adding pump stations so we can pump water out quicker"
While the timing of this story is meant to coincide with President Obama's speech on climate change, it unintentionally corresponds with a "king tide - when high tide coincides with the largest full moon". Denise Keener of the Environmental Protections Agency, Lyden's third guest, explains that "(t)he ineluctable tidal pull results in a storm surge without the storm".
Will the king tide serve as a "wake-up call for communities", as Keener hopes, so they can prepare for rising sea levels? If not, the 500% increase in homeowners insurance in the last decade might do so.
