The Ebola outbreak in Western Africa continues to make the news as more cases are reported and casualties rise. A common thread in reporting is the difficulty in communicating accurate information to...
Scientists have issued a new warning to the world’s coastal megacities that the threat from subsiding land is a more immediate problem than rising sea levels caused by global warming.
A new paper from the Deltares Research Institute in the Netherlands published in April identified regions of the globe where the ground level is falling 10 times faster than water levels are rising - with human activity often to blame.
In Jakarta, Indonesia’s largest city, the population has grown from around half a million in the 1930s to just under 10 million today, with heavily populated areas dropping by as much as six and a half feet as groundwater is pumped up from the Earth to drink.
The same practice led to Tokyo’s ground level falling by two meters before new restrictions were introduced, and in Venice, this sort of extraction has only compounded the effects of natural subsidence caused by long-term geological processes.
Elizabeth Borneman explores how cartography and cartographic projections help and hinder our perception of the world.
"How do you think the world (starting with our perceptions) could change if the map looked differently? What if Australia was on top and the hemispheres switched? By changing how we look at a map we truly can begin to explore and change our assumptions about the world we live in."
Geography doesn’t just teach us about the Earth; it provides ways for thinking about the Earth that shapes how we see the world. Maps do the same; they represent a version of reality and that influences how we think about places.
"This animation distils hundreds of years of culture into just five minutes. A team of historians and scientists wanted to map cultural mobility, so they tracked the births and deaths of notable individuals like David, King of Israel, and Leonardo da Vinci, from 600 BC to the present day. Using them as a proxy for skills and ideas, their map reveals intellectual hotspots and tracks how empires rise and crumble. The information comes from Freebase, a Google-owned database of well-known people and places, and other catalogues of notable individuals. The team is based at the University of Texas at Dallas."
"Last week, a major tourist thruway in Yellowstone National Park had to be shut down because the road melted. The road’s Wicked Witch of the West impression was caused by high temperatures in both the air and under the ground. Yellowstone sits atop a volcanic hotspot, and that heat helped cause the asphalt to soften and oil to well up onto the surface."
"Why are all the gas stations, cafes and restaurants in one crowded spot? As two competitive cousins vie for ice-cream-selling domination on one small beach, discover how game theory and the Nash Equilibrium inform these retail hotspots."
"The global Multidimensional Poverty Index (MPI) is an international measure of acute poverty covering over 100 developing countries. It complements traditional income-based poverty measures by capturing the severe deprivations that each person faces at the same time with respect to education, health and living standards."
As the climate shifts, rivers will both flood and dry up more often, according to the latest report from the Intergovernmental Panel on Climate Change. Shortages are especially likely in parts of the world already strapped for water, so political scientists expect feuds will become even more intense. To track disputes worldwide, researchers at Oregon State University spent a decade building a comprehensive database of international exchanges—-both conflicts and alliances—over shared water resources. They found that countries often begin disputes belligerently but ultimately reach peaceful agreements. Says Aaron Wolf, the geographer who leads the project, “For me the really interesting part is how even Arabs and Israelis, Indians and Pakistanis, are able to resolve their differences and find a solution.”
With Tuesday's seizure of Mosul, Iraq's second largest city, the Islamic State of Iraq and Syria notched a major victory in its campaign to create a new country containing parts of what had part of both Syria and Iraq. On Wednesday, the insurgents continued their march south, taking control of Tikrit, the hometown of Saddam Hussein.
