Nuclear Europe

30 years ago on this day the nuclear accident of Chernobyl brought the risks of nuclear energy production closer to the European population. Alongside the United States, Europe has the most dense network of nuclear power plants in relation to its population, as the below map shows. Of the producers of nuclear power in Europe, France (17.1%) and Russia (7.0%) are the largest when comparing it to the global share (France comes second after the USA). The United Kingdom’s production accounts for 2.9%. In contrast, France generates the largest share of its domestic electricity generation from nuclear power (74.4%) worldwide. It is followed by Sweden (43.4%) and Ukraine (43.0%), while the United Kingdom comes fifth with 19.2%.

In Focus: Where Art meets Science

Political InsightPublic spending cuts have been an important part of the political debate in Britain in recent years. In an article for the “In Focus” section of Political Insight (April 2016, Volume 7, Issue 1) Danny Dorling and I plotted the distribution of funding for the arts and universities in England.
The United Kingdom, and especially England, has become geographically extremely unequal. This inequality is not only seen in growing economic disparities within the population, but also becomes increasing visible across all parts of public life, such as science and education, as well as the arts. A report on arts funding in 2013, highlighted just how concentrated such funding was within London compared to the rest of the country. This represents the continuation of a now long-established trend.

World Population Cube


World Population CubeLast November’s theme of the Super Science Saturday at the Oxford University Museum of Natural History was Planet Earth. As part of the activities I contributed a map cube which I created a few years ago.
Cubic globes are not a new idea. They put a nice twist to showing just a simple map, and more importantly, they allow for some activity which get the kids involved just as much as adults. A cube is much less work than creating a spheric version of Earth, and (as said by Carlos Furuti on his online cube globe collection) the cube is an ideal introduction to folding one’s own pseudoglobes.
At last November’s Super Science Saturday I displayed some of my work and offered a ‘Map Cube Activity’ where children (and adults) could cut, fold and glue their own globes. My version of a map cube does not display a normal world map, but a gridded population cartogram (hence the name ‘World Population Cube’). You can create your own cube by using the following template: Continue reading

Air Spaces: Where the Planes Fly

Cartographic Summit 2016The Future of Mapping was the theme of a Cartographic Summit jointly held by the International Cartographic Association (ICA) and Esri at Esri’s headquarters in Redlands (California). The aim of the event was to examine new directions in mapping in a time at which mapping is evolving at a rapid pace, enabling us to communicate in new ways, analyze important issues, and understand our world. Among the keynote speakers was graphics designer Nigel Holmes whom I had a chance to work with several years ago while making some contributions for Lonely Planet’s travel-infographics book How to land a jumbo jet. Meeting him in person at last reminded me to put online the last of the four cartograms that I made for the book.
The following map is a gridded cartogram visualisation of global flight tracks taken from the OpenFlights database. The map distorts the land area by the number of flights that pass a certain space which leads to these ‘ploughing patterns’ over some areas where are airplanes basically just passing by, such as in the western part of Australia where planes simply fly over on their way to the most populated southeast of the country. The colours in the map relate to the Worldmapper colour scheme (explained here).

Global Temperature Anomalies

Recent figures released by the NASA as well as the British Met Office and NOAA confirm that 2015 was the hottest year ever recorded. In addition, the period of the past five years was also the warmest in recent times. The following map animation visualises a data series by NASA’s Goddard Institute for Space Studies (GISS) that depicts “how much various regions of the world have warmed or cooled when compared with a base period of 1951-1980. They show temperature anomalies, or changes, not absolute temperature. (The global mean surface air temperature for that period was estimated to be 14°C or 57°F.)” It uses an equal population project in form of a gridded cartogram so that the underlying temperature anomalies can seen in relation to the global population distribution:
