Analysing the Urban Environment

Via the Guardian comes an interactive piece from researchers at MIT and the Technical University of Lisbon that allows users to examine urban environments to compare population, energy use, and building material intensity for a select set of 42 different cities. The screenshots below are of neighbourhoods in Philadelphia.

Once the user has chosen an area, he or she can move on and analyse a different section of the city. This behaviour generates a comparison on the right of the current area to the previous area.

After the user has found an area of particular interest, he or she can generate a graphical report that summarises the findings for the selected area and compares that to other areas of similar scale in the city.

Let’s Talk About the Weather

Global warming is probably not the worst-branded concept out there, but it is not particularly effective. Mostly because it implies the world will warm and warm evenly. In truth, some parts will get colder, some parts drier, some parts wetter, and yes, some parts warmer. Hence the better term is climate change.

In the US, we have a tendency to be rather skeptical of climate change and the degree to which, if not whether entirely, it is due to mankind. So, the New York Times released the results of a survey about whether Americans believe recent weather events are related to global warming—their word choice, not mine.

While not all bars sum to 100, probably due to rounding, note how the bars are all aligned against the point of divergence between the scales of agreement and disagreement and then sorted according to agreement.

A Warm Winter in Canada

For many, this past winter was not so wintery, warmer than average temperatures and less than average snowfall. The National Post looked at Canada’s winter experience and found it to be the third-warmest in history. The story was covered in a large infographic piece that uses small multiples to look at previous Februaries across Canada and then bar charts to look at March temperatures specifically.

Rising Seas

Via the Guardian, Stamen Design has teamed up with Climate Central to create an interactive piece that maps the potential effects of rising sea levels. The user has control over the amount of the rise—this graphic says four feet—after which the coastline recedes to reveal the devastation. This is complemented by statistics of the land, including the population potentially affected along with the number of homes and total acres. In this case you see South Jersey, which is where I spent my summers. As you can see, the coastal beach towns I called home would be underwater. (And the little blue specks inland in Pennsylvania near my hometown, those are quarries; nobody lives there. No need to worry.)

The problem, of course, is that a large percent of the Earth’s population lives near the ocean. There are not, after all, many people living in the interiors of the continents. So receding coasts may very well be a problem in the coming years.

The Science of Cherry Blossoms

The Washington Post explains the science—or is it art—of the cherry blossom in D.C. though an illustrated video. Certainly this is literally more illustrative in concept than some other posts here, but the illustrations nonetheless match the audio explanations and parallel nicely with the aesthetic qualities of the cherry trees.

Fresh Water Bulge in the Arctic Ocean

The BBC has an article on a discovery of a growing bulge of fresh water in the Arctic Ocean. The top of the article includes a large set of graphics that explains the story below and links to an animation. The animation depicts the growth of the Arctic ice sheet from the pressure beneath and plots the height of the ice.

Exporting the Sun

Plans are afoot to harness the power of the sun in the deserts across northern Africa. The electricity generated in Morocco is planned to turn on light switches in Madrid and throughout the rest of Europe.

The Guardian created a map to show how the solar facilities could be connected to each other and to other renewable power sources in Europe—from Icelandic geothermal plants to North Sea wind turbines to Alpine hydroelectric plants.

Glaciers Aren’t So Slow After All…

Antarctica is a continent way down at the southern end of the world. It is covered almost entirely by glaciers. But glaciers move, and NASA and the University of California unveiled a map looking at the speed of the glaciers’ movements. Along with it, an interesting little video showing the tributaries to the glacial flow.
