Finding the World’s Economic Center of Gravity
djv:

Each point is the average of all economic activity for a certain year. You can see how the world’s economic center is moving as time progresses. The graphic was generated using publicly available data. I used Python for the data processing and plotting. Detailed write-up of the process

These swirling clouds captured by NASA’s Terra Satellite are known as Von Karman vortices.They are created when a mass of fluid, such as water or air, encounters an obstacle and creates swirls going in alternating directions.The obstacle in this instance is Isla Socorro, a volcanic island in the Pacific Ocean. The island, which is located a few hundred kilometers off the west coast of Mexico and the southern tip of Baja California, is part of the Revillagigedo Archipelago. JeanPhotograph: MODIS/Terra/NASA

Map of gerrymandering in the United States
Mainstay17:

Here is an interactive map of this from the Washington Post.


An explanation for non-American redditors: Each Congressional district elects one representative, so that more populated states have more than less populated states. This is intended to counterbalance the equal representation in the Senate. However, on many occasions both major parties wildly - wildly - redraw the borders of the districts to encompass as many voters from their party as possible.


For example, Party A redraws the borders in a state so that the people voting for Party B are clustered in one or two districts, and the people voting for Party A are spread out over all of the other districts.

African fibre-broadband network
NelsonMinar:

From this Economist article, about Liquid Telecom running Internet infrastructure inland in sub-Saharan Africa. I particularly like the way the map highlights the difference between oceanic cables providing access to the continent vs. inland cables bringing service to people. The last 1000 mile problem, with elephants and big rivers and a very complicated regulatory environment.

5 Scary Charts from the US Government’s National Climate Assessment
SOURCE: The Huffington Post 

In May [2014] the U.S. government released its third National Climate Assessment, writing that climate change is already “triggering wide-ranging impacts in every region of our country and throughout our economy.”

Wile the full report is over 800 pages, there’s a 137 page highlights document. The Huffington Post chose these five charts as most indicative of “how much things have changed in recent decades and what we might expect later this century.”

  1. We’re Seeing More Heavy Precipitation than We Used To
  2. It’s Gotten Warmer Almost Everywhere
  3. We’re Seeing a Lot of 100-Degree Days
  4. Drought Is Becoming a Major Problem for Much of the Country
  5. Business as Usual = More Temperature Rise
