If there is one U.S. state whose airports are most vulnerable to climate change, it is Florida, where many significant airports are at very low elevation. The busiest Florida airport, KMIA in Miami, is at 9-feet elevation. The state’s fifth-busiest airport, KFLL in Fort Lauderdale,* is also at just 9-feet elevation. The state’s sixth-busiest airport, KTMB to the southwest of Miami, sits at just 10-feet elevation.
As atmospheric CO2 continues to climb, it is expected that the massive amounts of ice on Greenland and Antarctica will continue to melt. The rates of melting in the past decade have increased substantially, and some now believe that we have passed a tipping point — that the meltoff is irreversible. If so, sea levels around the world are expected to rise by dozens of feet. Of course, how quickly the sea levels rise depends on how quickly the ice melts or slides off into the adjacent seas.
Considering the vulnerability of Florida aviation to climate change sea-level rise, it is shocking to see the diversity of reactions by Floridians. On the one extreme, Senator Marco Rubio is in full denial. Yet, on the other extreme, a major Christian group is bucking the conservative trend and speaking of how we have a moral and religious obligation to protect our environment:
“…Climate change just isn’t in faraway places. Florida, your home, literally represents “ground zero.” Sea level rise, more extreme weather, saltwater contaminated wells, loss of farm land and increased air pollution all pose significant threats to the health and well-being of Floridians. Unfortunately, a few in our nation are attempting to portray addressing climate change as a liberal issue. It’s not. It’s a moral challenge to all Americans. It is a call to follow our Risen Lord and act to prepare for the impacts, many of which are already happening, and to work to reduce our carbon pollution to help our children, now and in the future….”
One other area of the U.S. that is especially vulnerable: New York City. The three busiest airports there all average more than 1,000 operations per day and include: KEWR in Newark at 10-feet elevation, KJFK (Kennedy) in New York in Jamaica at 12-feet elevation, and KLGA (LaGuardia) at 12-feet elevation (and with one runway end at just 7-feet elevation).
