A study published by the Proceedings of the National Academy of Sciences projects future sea-level rise with a new model, providing crucial information for coastal planning and further impetus to cut carbon emissions. Sifting through data on thermal expansion and retreating glaciers, the two leading causes of sea-level rise in the past century, the authors confirm that sea level is rising at an unprecedented rate.

The climate agreement reached in Paris last December, seen by many as a critical step toward lowering greenhouse gas emissions, was big news – perhaps too big. Pointing to the thousands of articles about COP-21, National Geographic Senior Editor Marla Cone asked at a recent Wilson Center panel, “Is this a wise use of resources, when newsrooms are so stretched thin, to have everybody pretty much chasing the same stories?”

China’s “strictest air protection law” yet took effect on January 1, 2016, promising to bring big changes to its smog-filled cities. But some municipal governments have been ahead of the curve, working to clean up the air through experimentation and innovation. Shenzhen, China’s first special economic zone and which recently passed its neighbor Hong Kong to lead China’s most competitive cities, is one of these.

The new climate deal coming out of Paris commits governments to hold the rise in average global temperatures to “well below” two degrees Celsius compared to preindustrial levels. An important dimension of this agreement calls for subsequent work on limiting the increase to 1.5 degrees. This is an important win for islands and other low-lying countries, and for humanity.

In the hierarchy of global and national security challenges, climate change comes out near the top, said a panel of distinguished defense, diplomacy, and intelligence leaders at the Wilson Center on November 17. [Video Below]

As the UNFCCC Conference of the Parties (COP) gets underway in Paris, #resilience appears with increasing frequency on my Twitter feed, and I frequently hear talk about “socio-ecological resilience,” “climate-resilient development,” and “resilience programming.”

The Sundarbans – a collection of densely populated islands in India’s sprawling Ganges Delta – are so remote that the only way to get there is by boat. But human traffickers still manage to get in, and that’s left many families with missing daughters.
