Check out this cool site sponsored by NASA that compiles all of the surface temperature data from around the world, dating as far back as 1880 in some places. Pretty cool stuff. And no, it isn’t your imagination, it is getting much hotter in Miami.
A new report from the National Research Council shows that compact development, if done correctly, can result in reductions of VMT’s of up to 25% - over the next 40 years.
Requested by Congress and funded by the U.S. Department of Energy, Special Report 298: Driving and the Built Environment: The Effects of Compact Development on Motorized Travel, Energy Use, and CO2 Emissions examines the relationship between land development patterns and motor vehicle travel in the United States.
According to the committee that wrote the report, the most reliable research studies estimate that doubling residential density in a metropolitan area might lower household driving between 5 percent and 12 percent. If higher density were paired with more concentrated employment and commercial locations, and combined with improvements to public transit and other strategies to reduce automobile travel, household driving could be lowered by as much as 25 percent. By reducing vehicle use, petroleum use and CO2 emissions would also be lessened.
You can read the full report here. The long time horizon means that while compact development will play an important role in mitigating our carbon footprint in the long term, it will not be enough to slow the brunt of climate change in the short term.
The reason weather is rarely discussed on this site is because we think for the most part it is a non-issue. By and large,
Another thing to keep in mind is that most people commute early in the morning when temperatures are nearly at their coolest, which is certainly bearable even during
In poorly designed places, heat does have the potential to be oppressive. This is why it’s so important to adhere to quality urban design principles, with buildings having short setbacks coupled with awnings or sidewalk shade trees (this usually means higher density – one more reason why it’s not an evil thing). Mayor Diaz is trying to attack this issue with a Tree Master Plan, with goals to improve the City’s tree canopy by 30% by 2020. Developers need to do their part, too, by making their street frontages more protected from sun.
This is one more reason why low-density sprawl is so bad, especially in
And lastly, rain is definitely a non-issue for pedestrians - all you need is an umbrella!

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
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.
