Heads of state gathered in New York for the September 19 United Nations Summit on Refugees and Migrants will reaffirm principles of international law, pledge to treat asylum seekers more humanely, and promise to improve coordination between humanitarian and development organizations.

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.

Most citizens of democratic nations expect their governments to do their very best to make society more egalitarian, productive, adaptive, and resilient.

Without addressing the needs of people, conservation measures will not be very effective, and conversely, without conservation, people lose vital natural resources and suffer consequences to their health.

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.
