In August, Solomon Hsiang, Marshall Burke, and Edward Miguel published a provocative piece in Science in which they sought to demonstrate a correlation between climate extremes and violence across a range of time periods, countries, and different levels of conflict. It’s a massive undertaking and one that predictably has evoked some criticism – some of it warranted.

Population aging and decline are frequently described as a threat to countries’ economic development and social stability. Evocative language, such as “demographic winter” and “graying of the great powers,” portrays the serious consequences that many observers envision as fertility and growth rates decline and the elderly comprise a greater percentage of the population. These concerns reach around the globe, including in Africa, which has the lowest percentage of elderly among the world’s major regions.

At the end of June, the European Union Foreign Affairs Council adopted a set of conclusions on EU climate diplomacy that left us with mixed feelings. Acknowledging and recalling that climate change is of paramount importance is commonplace – too often quoted and very seldom followed by decisive action. Explicit reference to the positive results of the Durban and Doha climate conferences is even a reason to get nervous. Many negotiators and observers will doubt a similarly enthusiastic framing for the most recent results.

Developing countries will account for much of the world’s growth in agricultural production, demand, and trade during the next decade, as production growth in developed countries slows, according to reports from leading food policy organizations. The shift will pose challenges for the quality and abundance of water supplies in regions like South America, Asia, and Africa.

The disastrous flooding in the Himalayan state of Uttarakhand this summer, which claimed more than 6,000 lives, was the outcome of a changing climate and poorly planned development. It was also another case in point of the increasing importance of environmental security in India – especially for the military.

The black, blasted landscape of Wuhai City sometimes looks more like the moon than Inner Mongolia. But this scene is becoming all too common across much of Northern China. China’s massive coal industry is not only polluting the air and water, but also fundamentally altering the surrounding landscape and communities.

According to the UN, the planet has warmed faster since the turn of the century than any other period on record. Sea-level rise has also increased pace to 0.12 inches a year – almost double the rate observed during the 20^th century. This “unprecedented” rate of climate change is expected to disproportionally impact developing countries, whose socio-economic, political, and physical landscapes make them particularly vulnerable to the effects. The GAIN Index, an interactive mapping tool recently acquired by the University of Notre Dame, can help policymakers prepare for these changes by comparing the climate change vulnerability and readiness of countries around the world.

Fire needs oxygen to burn. When a fire starts inside a building, the floors, ceilings, walls, doors, and windows can constrict the flow of air. Breaking in to fight the fire thus carries the risk of opening a new airway. If that happens, a smoldering fire can expand explosively, bursting into roaring flames as it sucks air in through the new passageway. This sudden inrush of air to fuel a burst of fire has a name: backdraft.
