Is an Increase in Waterfront Property on the Horizon?

HRMiami-125M

The Miami Herald is reporting that County Commissioners, today, will hear a report from the “Miami-Dade County Climate Change Task Force,” in which data point to nothing less than a dramatic rise in sea levels on the horizon.

What does this have to do with transportation in Miami? Some of the suggestions for improvement from the task force are interesting:

  • Phasing out “gas-guzzler” taxis by 2008
  • Burning bio-fuels in county fleet vehicles

While the article points out that there are zoning changes that are also part of the recommendations, the article does not point out the impact the daily commute has on our atmosphere here, and worldwide. It seems to take a bleak look overall at the scenario, without the proper focus on anything except pie-in-the-sky suggestions such as the aforementioned, which suggestions are all-but-certain to be obliterated by lobbyists before they see even a pilot implementation.

What is clear (and this is also presented by the article) is that Everglades restoration needs to be the first and foremost on everyone’s mind right now, as this will at least delay the salt water invasion some of our water well fields are already experiencing. Next, since this looks like it will happen sooner, rather than later, perhaps it’s time to start looking at some of the flood protection that has been implemented in coastal areas of mainland Europe, and on the British Isles.

Finally, while the county had the forethought to actually implement this sort of task force, bringing their ideas to fruition may take a lot longer than we have. What incentive is there to implement? The water isn’t lapping at our feet yet.

Climate Change and South Florida

Our global warming crisis continues to become more foreboding. Today the Herald reported findings from a recent study that predicts serious local climate change in South Florida’s future. According to the study, which is one of the first to predict local climate change stemming from global warming, by 2100 South Florida will likely have a novel climate that is warmer, drier, and unlike any other on Earth. Among the findings:

  • Mean temperatures in South Florida could rise by 5-7 degrees Fahrenheit during the summer/wet season (+ 3 ½ degrees in the winter/dry season)
  • High temperatures in the mid-to-upper 90’s can be expected during the summer/wet season
  • Much drier conditions: 3 ½ fewer inches of rainfall during the wet season (Note: Drier does not mean less humid)
  • Even if worldwide action reduces greenhouse gas emissions, 4-20 percent of the world’s land could experience novel climates
These findings have grave implications for South Florida. As I noted above, a “drier” climate does not mean a less humid climate. High temperatures in the mid-to-upper 90s coupled with high humidity would make it feel like 110-120 degrees based on heat indexes. Also to consider, the 5-7 degree rise is in mean temperature, which is the average temperature over a 24-hour period. For the last 30 years, Miami’s mean temperature has averaged about 83 degrees during the peak of the summer/wet season. If the predictions are true, then our average daily temperatures could be as high as 90 degrees! Imagine stifling days with highs of 95 and lows of 85. Factor in humidity, and even our nights would feel as warm as 100 degrees!

All of this does not even consider the potentially catastrophic effects of rising sea levels, increased frequency of major hurricanes, drought, and the decimation of the Everglades. It is now critical that we begin making major changes in the way we live and the way our cities function. Given the implications of climate change in South Florida, you would think that our region would be on the leading edge of sustainable urban planning. Sadly, as we all know, this is not currently the case. Yes, Mayor Diaz should be complemented for his green building proposal, Miami 21, and the Miami Streetcar initiative, but this barely scratches the surface of sustainability. We need a progressive, regional effort to significantly reduce our dependence on the automobile, boost alternative transportation modes, and design sustainable, pedestrian-oriented neighborhoods. We cannot wait any longer to act.
