A couple of articles related to global warming got my attention recently. First, the Washington Post had an article about plant species common to North Carolina now finding their homes in the District of Columbia and environs. The article quotes the curator of the United States Botanical Garden as saying, "You could say D.C. is the new North Carolina." The article included a map (at right) that shows how the true that statement is.

Some of us at Streetsblog headquarters were talking about putting together a sidebar listing of recommended books to reinforce the commentary you find on the blog. I put together a few brief recommendations of five of my favorites, but we're also interested in learning what you've all been reading and what you'd suggest to others, so treat this as an open thread on livable streets-related books now that we're in the midst of the holiday gift-buying season.

One of those subtle aspects of life that serves to normalize auto transport as the only thing going is the way most maps are designed to barely include railroad tracks and stations, presumably so as to avoid interfering with roads and Interstates and their giant identification shields. But when we plug some fun data into Google mashup mapping, it is clear that the rail system serving the metropolitan area is extensive, probably more extensive than most people realize. This screenshot shows the location of stations served by New York City's four passenger railroads: Metro-North in blue, NJ Transit in green, the LIRR in red and Amtrak in purple.

Via the Manhattan Institute's new blog, Streetsblog learns of a pdf-formatted report entitled A Heavy Load: The Combined Housing and Transportation Burdens of Working Famillies, which looks at the housing and transportation expenses paid by lower income families in a number of cities. The report, published by the Center for Housing Policy, a K Street think tank, finds that lower-income families in central cities spend significantly less on the overhead of life than suburban and exurban ones.

In his weekly radio address yesterday, Mayor Bloomberg discussed some steps his administration is taking toward a sustainable future, including the creation of an Office of Long-Term Planning and Sustainability, and a Sustainability Advisory Board, which held its first meeting last week.

Of the ten largest cities in the United States, New York has far and away the greatest population density: 26,402.9 people per square mile, more than double the second densest big city, Chicago. The chart at right shows how the largest metropolitan areas stack up in terms of core population, overall population and core population density.  This fact alone should force New York City authorities to think differently than the rest of the country on all sorts of matters of public policy. New York is a quantitatively different animal than the other big American metropolitan regions in terms of percentage of people that live in the core, density and size of the core and size of the metropolitan area.
