In this speculative world map published in 2009, New Scientist imagines what the world might look like if (or more likely, when) the Earth warms by 4ºC. Many current coastal areas would be underwater and much of the most heavily populated areas of the Earth would be desert or otherwise uninhabitable while the northern parts of Canada and Russia would become the new bread baskets of the world. But on the plus side, western Antartica would be habitable and possibly “densely populated with high rise cities”. In an article that accompanied the map, Gaia Vince wrote:
Imagine, for the purposes of this thought experiment, that we have 9 billion people to save — 2 billion more than live on the planet today. A wholesale relocation of the world’s population according to the geography of resources means abandoning huge tracts of the globe and moving people to where the water is. Most climate models agree that the far north and south of the planet will see an increase in precipitation. In the northern hemisphere this includes Canada, Siberia, Scandinavia and newly ice-free parts of Greenland; in the southern hemisphere, Patagonia, Tasmania and the far north of Australia, New Zealand and perhaps newly ice-free parts of the western Antarctic coast.
The citizens of the world’s wealthiest and most populous nations will become climate refugees, which means things are going to get really, really ugly for everyone else.
In 1990, China, Hong Kong, and Taiwan had only a handful of subway lines. In the early 2000s, growth in the number of cities with subways started to increase dramatically, as did the number of lines in the bigger cities like Beijing and Shanghai. As of 2020, more than 40 Chinese cities will have subway systems. Check out this time lapse map by “transit nerd” Peter Dovak (who also did these Mini Metros maps):
In this time, Beijing and Shanghai in particular have ballooned from nearly nothing into the world’s two largest, in both length and annual ridership. The timeline of their expansion alone is mesmerizing.
NASA has built a service for estimating populations, part of which is a map hosted by Columbia on which you can draw a circle or a shape and the map will give you an estimate of the population contained by the shape. You can also access the service via an API…just send it polygonal coordinates and it returns population data.
Just for fun, I drew a small circle with an area of ~7000 sq. km and dragged it around to different spots on the globe:
Have you ever wondered why, when you’re driving along on a straight road in the Western US, there’s a weird curve or short zigzag turn thrown into the mix? Grids have been used to lay out American roads and houses since before there was a United States. One of the most prominent uses of the grid was in the Western US: the so-called Jefferson Grid.
The Land Ordinance of 1785, drafted by Thomas Jefferson, extended government authority over the Mississippi River and the Great Lakes regions. As a response to what he believed to be a confusing survey system already in use, Jefferson suggested a new grid system based on the rectangle. The grid divided land into plots one mile square, each consisting of 640 acres. The grid also placed a visible design upon a relatively untouched landscape.
As most people know, the Earth is roughly spherical. When you try to cover the surface of a sphere with squares, they are not going to line up perfectly. That means, every so often, sections of the grid shift away from each other. Gerco de Ruijter’s short film, Grid Corrections, shows dozens of examples of places where this shift occurs and the corrections employed to correct them.
By superimposing a rectangular grid on the earth surface, a grid built from exact square miles, the spherical deviations have to be fixed. After all, the grid has only two dimensions. The north-south boundaries in the grid are on the lines of longitude, which converge to the north. The roads that follow these boundaries must dogleg every twenty-four miles to counter the diminishing distances.
If you want to look at some of the corrections yourself, try this location in Kansas (or this one). See that bend? Now scroll the map left and right and you’ll see a bunch of the north/south roads bending at that same latitude.
Hi son, just reading your blog on the section lines….don’t forget, you used to live on a correction line…that is why 3 of my 40’s were only 26.3 acres….
“40’s” refers to 40 acre plots…a common size for a parcel of land back when that area was divvied up. Wisconsin has so many lakes, rivers, and glacial features that interrupt the grid that it’s difficult to tell where the corrections are, but looking at the map, I can see a few roads curving at that latitude. Cool!
Credit can be a lifeline during emergencies and a bridge to education and homeownership. But debt-which can stem from credit or unpaid bills-often burdens families and communities and exacerbates wealth inequality. This map shows the geography of debt in America at the national, state, and county levels.
I’d love to hear why the “share with any debt in collections” is so relatively low in the Upper Midwest, Minnesota in particular.
The Washington State Geological Survey is using LIDAR technology to study the geology of the land hidden under forested areas of the state. LIDAR is like radar, but instead of bouncing radio waves off of objects to detect their distances, you use lasers. When you shoot laser light at a forested area, most of it is reflected back by the trees. But some of it reaches the ground, so by measuring the light that’s reflected back from the lowest point, you get a very accurate map of the bare earth, sans nature. Using the LIDAR maps, they can study the course changes in rivers, landslides, volcanic lava flows, earthquake faults & fault zones, tsunami inundation zones, and glaciers.
The beautiful photo at the top is a LIDAR image of the Sauk River and all its current and former channels…the bluish tint makes it look like an x-ray, which it pretty much is. It also reminds me of the meander maps of the Mississippi River made by Harold Fisk for the US Army Corps of Engineers.
Here are two images of Bainbridge Island:
The LIDAR image clearly shows a horizontal earthquake fault scarp that’s completely hidden by the ground cover.
These two images are of drumlins left behind by a glacier:
Again, the LIDAR image shows the movement of a long-gone glacier with stunning clarity compared to the satellite photo with ground cover.
Strava, makers of apps that allow people to track and share their athletic activities, have released a global heatmap, a visualization of the humanity’s collective athletic activities. In a recent blog post, the company highlighted some of the most interesting spots on the map, which was created using 27 billion miles of data representing over 200,000 years of hiking, biking, running, skiing, and other sporting activity. Pictured above are the ski areas near Salt Lake City and kiteboarding in Baja, Mexico.
A Tapestry of Time and Terrain is a map from the USGS that shows the topology and ages of rock underneath the surface of the United States. The age scale on the right is difficult to read unless you download the full 45Mb PDF version, but it goes from Precambrian (2.6 billion years ago) at the bottom to more-or-less the present day at the top.
Through computer processing and enhancement, we have brought together two existing images of the lower 48 states of the United States (U.S.) into a single digital tapestry. Woven into the fabric of this new map are data from previous U.S. Geological Survey (USGS) maps that depict the topography and geology of the United States in separate formats. The resulting composite is the most detailed and accurate portrait of the U.S. land surface and the ages of its underlying rock formations yet displayed in the same image. The new map resembles traditional 3-D perspective drawings of landscapes with the addition of a fourth dimension, geologic time, which is shown in color. This union of topographic texture with the patterns defined by units of geologic time creates a visual synthesis that has escaped most prior attempts to combine shaded relief with a second characteristic shown by color, commonly height above sea level (already implicit in the shaded relief). In mutually enhancing the landscape and its underlying temporal structure, this digital tapestry outlines the geologic story of continental collision and break-up, mountain-building, river erosion and deposition, ice-cap glaciation, volcanism, and other events and processes that have shaped the region over the last 2.6 billion years.
If you superimpose the Mediterranean Sea (and the Black Sea) over a map of the United States (map by Bret Drager) — creating geographic landmarks like the Confederate Sea, the Great Salt Islands, the Straits of Pismo, and a coastal Las Vegas — you get a real sense of how big each of them is. I confess, I didn’t think the Mediterranean Sea was this large. The other surprising thing is that the latitudes of the superposition are pretty accurate…only a degree or two off, if that.
Last year, the NOAA updated their Climate Explorer tool, which lets you see how climate change will affect the weather (daily max/min temperatures, really hot & cold days, precipitation, etc.) in different parts of the United States. For example, if emissions of greenhouse gases continue to increase throughout the next 80 years, the average temperature in Miami will increase from a current ~84.5 °F to over 91 °F in 2100…and even worse, the annual number of 95+ degree days will go from less than 10 to 140.
Which actually isn’t that big of a deal because a bunch of the city will be underwater and uninhabitable because of rising sea levels. Ok, moving on…
You live in the northeast and like to ski? Well, that might be a problem in the future. In Stowe, VT, the annual number of days with minimum temperatures below 32 °F will decrease from about 175 now to ~140 by 2070 even if emissions of greenhouse gases start dropping in 2040.
And if emissions don’t drop, Vermont could only see ~105 days of minimum temperatures below 32 °F by 2100. Goodbye ski season.
Design studio Dorothy has released this poster of a map of hip hop history, featuring notable rap and hip hop artists and groups laid out in the style of a circuit diagram for a classic turntable.
The print pays homage to the godfathers of hip-hop (Gil Scott-Heron, The Last Poets) but takes its starting point as DJ Kool Herc’s Back to School Jam in August 1973 — a block party in the Bronx, New York which is widely regarded as the birthplace of hip-hop.
The print weaves it way through many different scenes and record labels including early old-school innovators (Grandmaster Flash and the Furious Five, DJ Kool Herc, Afrika Bambaataa, Cold Crush Brothers), golden age heroes (Run-DMC, Beastie Boys, KRS-One, Eric B. & Rakim), the collective Native Tongues (De La Soul, A Tribe Called Quest, Jungle Brothers, Queen Latifah, Monie Love), politically charged hip-hop (Public Enemy, The Disposable Heroes of Hiphoprisy, Lauryn Hill), legendary East Coast artists (The Notorious B.I.G, Nas), legendary West Coast artists (Tupac Shakur, Dr. Dre), gangsta rap (Ice-T, N.W.A, Ice Cube, Snoop Dogg), hardcore (Wu-Tang Clan, Mobb Deep), Southern rap (Lil Wayne, T.I., Outkast) underground hip-hop (Company Flow, MF Doom, Aesop Rock), turntablism (Invisibl Scratch Piklz, The X-Ecutioners), trip-hop (Massive Attack, Tricky, Portishead), UK grime (Wiley, Skepta and Stormzy) and legendary producers (DJ Premier, J Dilla and Madlib).
It’s September 1st and currently 52° here in VT (low tonight of 38°) which means summer is over. :| But luckily fall is pretty great here as well. Once again, SmokyMountains.com has the best fall foliage prediction map around.
The 2017 Fall Foliage Map is the ultimate visual planning guide to the annual progressive changing of the leaves. While no tool can be 100% accurate, this tool is meant to help travelers better time their trips to have the best opportunity of catching peak color each year.
The subway and the street level of NYC are two very different worlds and even long-term residents have a difficult time understanding how they fit together. Architect Candy Chan has drawn a series of x-ray maps of NYC subway stations that show their layouts and orientation compared to the geography of the streets above. (Tip: you can zoom the maps for more detail.)
This was far more complicated than I had initially anticipated. Not only were there way more Roman Roads in Britain than I initially thought, but also their exact locations and extents are not very clear. In a few places I had to get rather creative with the historical evidence.
As Wikipedia notes, most of the roads were completed by 180 AD and many of them are still in use today.
After the Romans departed, systematic construction of paved highways in the UK did not resume until the early 18th century. The Roman road network remained the only nationally-managed highway system within Britain until the establishment of the Ministry of Transport in the early 20th century.
In just the past 10 years, the number of earthquakes in the central US (and particularly Oklahoma) has risen dramatically. In the 7-year period ending in 2016, there were more than three times the number of magnitude 3.0+ earthquakes than in the previous 36 years. Above is a video timeline of Oklahoma earthquakes from 2004-2016. At around the midpoint of the video, you’ll probably say, “wow, that’s crazy”. Keep watching.
Wastewater disposal wells typically operate for longer durations and inject much more fluid than hydraulic fracturing, making them more likely to induce earthquakes. Enhanced oil recovery injects fluid into rock layers where oil and gas have already been extracted, while wastewater injection often occurs in never-before-touched rocks. Therefore, wastewater injection can raise pressure levels more than enhanced oil recovery, and thus increases the likelihood of induced earthquakes.
Of course, this wastewater is a byproduct of any oil & gas production, including fracking. But specifically in Oklahoma’s case, the induced earthquakes have relatively little to do with fracking:
In contrast, in Oklahoma spent hydraulic fracturing fluid represents 10% or less of the fluids disposed of in salt-water disposal wells in Oklahoma (Murray, 2013). The vast majority of the fluid that is disposed of in disposal wells in Oklahoma is produced water. Produced water is the salty brine from ancient oceans that was entrapped in the rocks when the sediments were deposited. This water is trapped in the same pore space as oil and gas, and as oil and gas is extracted, the produced water is extracted with it. Produced water often must be disposed in injection wells because it is frequently laden with dissolved salts, minerals, and occasionally other materials that make it unsuitable for other uses.
Each of the 50 US states made of food and named accordingly, e.g. Arkanslaw, Pretzelvania, Tunassee, Mississippeas. Maps? Food? Language? How many more of my boxes could this project possibly check? Oh, this was a kid’s idea and his dad went over the top in helping him achieve it? CHECK.
Oh, and to teach the kid about capitalism, of course there are t-shirts and posters available.
The Washington Post has a cool series of maps related to the total solar eclipse happening in August. The one above is a one-shot view of what the Sun will look like across the US on August 21 and there are other maps with captions like “The last eclipse over these areas occurred before Columbus’s arrival in 1492” and “Total solar eclipse paths over the continental U.S. since 2000 B.C.”
In the last 100 years, some areas have been in the paths of multiple eclipses: New England, for example, saw four. (During its World Series dry spell from 1918 to 2004, the greater Boston area alone saw two.)
Others weren’t so lucky. Just 200 miles away in New York, construction on the Empire State Building had not started yet the last time the city saw a total solar eclipse (1925). San Diego had a population of less than 100,000 the last time it was eclipsed (1923), and Chicago hasn’t seen a total eclipse at all in the last 100 years. An area near Tucson has the longest dry spell in the Lower 48: The last total solar eclipse it saw was in the year 797.
The U.S. mainland has averaged about seven total solar eclipses per century since 2000 B.C. Some areas have seen as many as 25 eclipses, while others, such as spots west of Minneapolis, have seen only four in the last four millennia.
Per Betteridge’s law of headlines and also the map above, my answer is clearly no. You can try it yourself here…you draw them one at a time and it adds them to the map automagically. I’m going to blame my trackpad use a little, but I’m not sure I would have done much better had I drawn with a pencil and looked a map beforehand.
Update: Your periodic reminder that Senator Al Franken can draw all 50 US states from memory with astonishing accuracy.
Coming almost 450 years after the world’s first Atlas, this Atlas for the End of the World audits the status of land use and urbanization in the most critically endangered bioregions on Earth. It does so, firstly, by measuring the quantity of protected area across the world’s 36 biodiversity hotspots in comparison to United Nation’s 2020 targets; and secondly, by identifying where future urban growth in these territories is on a collision course with endangered species.
Standing at the edge of the moon’s shadow, or umbra, the difference between seeing a total eclipse and a partial eclipse comes down to elevation — mountains and valleys both on Earth and on the moon — which affect where the shadow lands. In this visualization, data from NASA’s Lunar Reconnaissance Orbiter account for the moon’s terrain that creates a jagged edge on its shadow. This data is then combined with elevation data on Earth as well as information on the sun angle to create the most accurate map of the eclipse path to date.
You can download maps of your area from NASA’s official eclipse website…I will be studying the Nebraska map closely.
After much research, Sasha Trubetskoy has completed a subway-style map of the road system of the Roman Empire. From about 300 BC, the Romans built or improved over 250,000 miles of roads (50,000 miles were stone paved) that extended into the farthest reaches of the Empire: from Spain to modern-day Iraq to Britain to northern Africa.
Creating this required far more research than I had expected — there is not a single consistent source that was particularly good for this. Huge shoutout to: Stanford’s ORBIS model, The Pelagios Project, and the Antonine Itinerary (found a full PDF online but lost the url).
The lines are a combination of actual, named roads (like the Via Appia or Via Militaris) as well as roads that do not have a known historic name (in which case I creatively invented some names). Skip to the “Creative liberties taken” section for specifics.
The Paleobiology Database Navigator is a world map that shows where hundreds of thousands of fossils have been found. The data is maintained by an international group of paleontologists and you can filter the map by type of fossil and when it was found. There’s even a toggle to flip back and forth between the current placement of the continents and much earlier Pangea-like configurations. (via @srikardr)
Today they are releasing a new global composite map of night lights as observed in 2016, as well as a revised version of the 2012 map. The NASA group has examined the different ways that light is radiated, scattered and reflected by land, atmospheric and ocean surfaces. The principal challenge in nighttime satellite imaging is accounting for the phases of the moon, which constantly varies the amount of light shining on Earth, though in predictable ways. Likewise, seasonal vegetation, clouds, aerosols, snow and ice cover, and even faint atmospheric emissions (such as airglow and auroras) change the way light is observed in different parts of the world. The new maps were produced with data from all months of each year. The team wrote code that picked the clearest night views each month, ultimately combining moonlight-free and moonlight-corrected data.
Scientists are planning on providing “daily, high-definition views of Earth at night” starting later this year. It’s worth clicking through to play with the interactive India map…it’s astounding to see how much light the country has added in the past 5 years. And see if you can spot North Korea at night:
Zak Ziebell asked 30 people to sketch a map of the world and then averaged the results into the map above. I especially love the bottom one with the satellite terrain.
Tasked with creating “a piece of art that would reveal something unseen” as part of a pre-college fine arts program, Ziebell approached 29 strangers on the University of Michigan’s campus, handed them a pen and half a sheet of paper, and asked them, on the spot, to draw a map of the world. Ziebell, who recently posted his findings to Reddit, then completed the task himself and digitally merged the 30 maps into one image, overlaying the composite drawing with satellite data.
From Aron Strandberg,1 this is a timeline visualization of the age of the world’s population from 1960-2060. The world’s human population has increased rapidly in the last couple centuries, most recently doubling since 1970:
A tremendous change occurred with the industrial revolution: whereas it had taken all of human history until around 1800 for world population to reach one billion, the second billion was achieved in only 130 years (1930), the third billion in less than 30 years (1959), the fourth billion in 15 years (1974), and the fifth billion in only 13 years (1987).
But watching that video, you’ll realize that the world’s population will not reach 20 or 30 billion in 2050 — human civilization is getting old.
