A bipartisan group of defense experts and former military leaders are calling on the next administration to consider climate change as a grave threat to national security.

Accurate measurements of wealth are useful for developing more targeted and effective poverty reduction programs. Unfortunately, such metrics are few and far between, as data on economic livelihoods tends to be expensive to obtain, and once collected, is often unreliable.

Featured side by side at the top of The New York Times home page recently were two stories: one on the United States and China, the world’s largest producers of carbon emissions, committing to a global climate agreement, another on how rising seas are already affecting coastal communities in the United States.

A study published in PNAS highlights the unpredictability of the impacts of climate change on water resources by comparing detailed simulations in mountain areas of Chile and Nepal. Authors Silvan Ragettli, Walter W. Immerzeel, and Francesca Pellicciotti study the response of river flows to a significant decline in glacier areas in the Juncal catchment of Chile and the Langtang catchment of Nepal at higher spatiotemporal resolutions than any previous study.

Although separated by a thousand miles, the women of the Malaysian state of Sarawak and the Filipino island of Mindoro are united by a major struggle: climate change. As rainfall patterns grow increasingly unpredictable, natural disasters become more frequent, and drought ravages once-arable land, women are on the frontlines in both communities.

When wildfires become unstoppable, consuming forests, farmlands, communities, and anything else in their path, how will those affected cope? When typhoons slam coastal populations, dumping over a foot of rain in a single event, who will be there to help mop up? When seas rise up, drowning centuries-old communities, where will the displaced go?

“The time for talk is done; it is now the time for action,” says Inger Andersen, director general of the International Union for Conservation of Nature (IUCN), in an interview before the 2016 World Conservation Congress.

Conflict is typically viewed as a failure of social and political systems and almost never as a method of transforming dysfunctional or fractured societies into cohesive units. However, in an analysis of the discourse around climate change and conflict in Local Environment, Melissa Nursey-Bray concludes that conflict is a sometimes-necessary step in a complicated process to create stable societies. Nursey-Bray separates the climate-conflict discourse into two baskets: climate change as a security risk and climate change as one of many factors that contribute to insecurity.
