If we are to avert the worst of climate change impacts, we need better tools for identifying patterns of displacement and migration around climate extremes. In vulnerable developing countries, increasingly frequent and intense storms will likely exacerbate current patterns of displacement and permanent migration. Displacement often leads to humanitarian crises in the short term and can derail progress toward development in the long term. Because of this dangerous potential, displaced persons and migrants are a common focus in humanitarian responses. However disaster responders must often “fly blind” without the benefit of current, accurate information about the worst-affected populations. To better respond to the impacts of climate change as they unfold, we will need more rapid, cost-effective, and accurate methods for identifying patterns of displacement and migration.

Most African states are more vulnerable and less prepared to address climate change challenges than the rest of the world. This observation is supported by a wide variety of sources, including the Climate Vulnerability Index and the Notre Dame Global Adaptation Index. And in fact Africans and their political leaders frequently observe that this crisis, manufactured in the developed world, disproportionately affects their continent. During a meeting of the African Union in 2007, Ugandan President Yoweri Museveni called climate change “an act of aggression” by the rich against the poor.

It might seem strange to say that the deep sea, the vast expanse of the world’s oceans beyond the continental shelf, is at risk of conflict and competition. After all, no one lives there, and as is often said, more is known about the surface of the moon than most parts of the ocean floor. But the fact is, even the cold, dark reaches of the ocean are no longer immune to resource competition between the world’s major powers.

The idea that climate change is causing migration and displacement is entering the mainstream, but experts have warned against using the term “climate refugees” to describe what we’re seeing in small islands, coastal regions, and even conflict zones like Syria.

Times are good for Fey Wei Dong. A genial, middle-aged businessman based in Hangzhou, Fey says he is raking in the equivalent of $225,000 a year from trading in the humblest of commodities: sand.

One of the findings of the Worldwatch Institute’s Family Planning and Environmental Sustainability Assessment (FPESA) suggests it’s not accurate to claim that climate change is at the root of growing water scarcity around the world. Based on the best recent scientific evidence we could find, another major global trend – the ongoing growth of human population – has a greater impact on water availability than climate change does.

The International Expert Forum (IEF) is a series of seminars meant to facilitate dialogue between experts and policymakers on peace and security. Meeting in Stockholm this past May, the forum explored the connections between environmental issues, peacebuilding, and conflict while considering how environmental governance can aid in peacebuilding. The summary brief produced after the forum provides a useful snapshot of a fast-changing field of study.

One fear of climate change is that more variable weather conditions will lead to violence and chaos in some places. But looking at it methodically, do erratic weather conditions actually lead to violent conflict and political instability? Not necessarily.
