Visual guide for the fires in Australia

For The Guardian, Niko Kommenda and Josh Holder provide a visual guide to the bushfires in Australia: Satellite data from Nasa showed a stark increase in the number of fire detections in November and December compared with previous years. Satellites detect fire “hotspots” by measuring the infrared radiation emitted by the blazes. In previous years, between 2,000 and 3,000 such hotspots were recorded each December in the south-east, while in...

Arctic ice melting

One way to gauge the amount of ice in the Arctic is to look at the average age of the ice. From the NASA Scientific Visualization Studio, the map above shows the estimated age of ice on a monthly basis, going back to 1984: One significant change in the Arctic region in recent years has been the rapid decline in perennial sea ice. Perennial sea ice, also known as multi-year...

Using old ship logs as a window into the weather in the 1800s

For Reuters, Feilding Cage describes a weather time machine project by NOAA that uses old shipping logs to build climate models for the 19th century: In the 19th and early 20th centuries, millions of weather observations were carefully made in the logbooks of ships sailing through largely uncharted waters. Written in pen and ink, the logs recorded barometric pressure, air temperature, ice conditions and other variables. Today, volunteers from a...

Making the most detailed map of auto emissions in America

Using estimates from the Database of Road Transportation Emissions, Nadja Popovich and Denise Lu for The New York Times mapped auto emissions at high granularity. Popovich described their process on Storybench: I want to make graphics that really resonate with people. If that is your goal as a visual journalist, something to think through is just how you can tie data back to a more human experience. To kind of...

Hotter days where you were born

It’s getting hotter around the world. The New York Times zooms in on your hometown to show the average number of “very hot days” (at least 90 degrees) since you were born and then the projected count over the next decades. Then you zoom out to see how that relates to the rest of the world. I’ve always found it interesting that visualization and analysis are typically “overview first, then...

Art piece uses wind energy to mine cryptocurrency and then fund climate research

HARVEST is an art piece by Julian Oliver that consists of a 4G-connected waterproof computer connected to a wind turbine. While it is powered by the wind, the computer mines for for cryptocurrency, and earnings are then cashed out as donations to climate change research organizations. Yeah. Tags: climate, crytocurrency

Climate Change Coloring Book

The Climate Change Coloring Book by Brian Foo makes data tactile and interactive. “The goal is to encourage learning, exploration, and reflection on issues related to climate change through act of coloring.” It’s in the early days of a Kickstarter campaign, but I suspect it’ll be funded in no time. Pledged. Tags: book, climate, environment

Are People in Colder Countries Taller? (Continued…)

Earlier this week I posted two scatterplots examining the relationship between a country’s average temperature and its male residents’ average height. The data show some correlation, but there probably are several of other factors affecting height as well. The earlier plots shaded the country dots by income and region, allowing more context about the groupings of countries (hint: Europe is colder and taller). This next version, however, proportionally sizes the...
