Map Monday: Will Global Warming Drown Your Hometown?
You may recently have read about climate change and North Carolina for all the wrong reasons, entailing laws designed to forbid the mentioning of the term "climate change" as well as outright banning measurements of sea-level rise.
City-Scale Congestion Pricing Picking Up Steam
What is congestion charging? Congestion charging or pricing is the practice of setting up cordon tolls around the city on a large-scale to charge entrants for entering during peak hours.
Top 10 (Transport) Sights in Paris
Few tourists travel explicitly to see a city’s or country's mode of transportation, but I dare say that besides transport nerds such as myself, there are examples which qualify as must-see, including Japan's Shinkansen high-speed train, Lisbon's old tram system, and the streetcars of New Orleans, among others.
Fuel/Cost Savings of Improving Fuel Economy from 12->15 mpg = 30->60 mpg
Consumer tip-of-the-day: increasing efficiency of fuel economy on a miles-per-gallon scale is not linear, as more miles-per-gallon (mpg) are initially better for your wallet and the planet than you might expect, and eventually trail off with diminishing returns.
Battleship Barcelona: When Child-Like Simplicity Saves the Day
I am one of those people who always thought Barcelona would be my favorite city in the world. I visited several times, and though the weather, design, and food leave you wanting little else, there was always something about the sheer number of tourists (besides myself) and traffic that put me off the whole experience.

Or rather, what if we managed to reduce CO2 emissions to necessary levels, what would our focus be on [...]
Map Monday: 50+ Shades of Air Pollution
In today's installment of Map Monday, I wanted to focus on air pollution as mapped by Hsu et al and The Atlantic. Go to this link to see the full interactive map, which details air pollution by country and city.
Map Monday: Economic Importance of Transport
Like most people, I am a sucker for a good map. To indulge in this nerdity, I am launching an occasional Map Monday series, beginning with one by Simran Khosla of GlobalPost who used the CIA Factbook to put together an excellent map detailing every country's highest-valued export.
Desire to Drive Flagging in the U.S. and Abroad
In the last post I presented results from my poll on the importance of cars to your everyday life. The results suggest, simply put, that its importance is sliding downwards.
SciAm Readers Prioritize MP3s Over MPGs
Thank you for your input as no less than 100 readers were kind enough to participate in my not-so-scientific survey of what is least important to them, when given a choice to give up one item ranging between a TV, vehicle, laptop/tablet, and a smartphone.
Full Frontal Nerdity
I was once caught staring at energy efficiency guru Amory Lovins' pocket protector, and without blinking he said, "Yes, it's full frontal nerdity." There was something refreshing about that sentiment, so let me similarly make my intentions clear: in joining SciAm Blogs, I hope to bring you some unnoticed news and engage you on a [...]
