There may not have been a single question about climate change in the 2016 presidential debates, but it remains a hotly contested, partisan issue for many in the United States. That climate change is happening and requires a response is not up for debate within the upper echelons of the U.S. military, however.

“Climate change is one of the greatest challenges of our time and it calls for a comprehensive and cooperative international approach like we’ve never seen,” said Jainey Bavishi, associate director for climate preparedness at the White House Council on Environmental Policy, at the Wilson Center on October 5. “The leadership of the island nations is essential; they punch well above their weight on this issue.”

“By 2050 the world urban population is expected to nearly double, making urbanization one of the 21st century’s most transformative trends.” -Draft “Quito Declaration on Sustainable Cities and Human Settlements for All,” September 2016

Over the course of 1,800 miles, 5,300 vertical feet, and at least five name changes, the Brahmaputra River, in sometimes turbulent outbursts, flows from the Tibetan plateau to the Bay of Bengal. Along the way, it crosses three countries, including major geopolitical rivals China and India, and supplies 90 percent of downstream Bangladesh’s freshwater during the dry season.

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.

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?
