Friction between Japan and China in the East China Sea has escalated this year to the point where jets on both sides have been scrambled and Chinese military vessels have locked their fire control radar onto their Japanese counterparts multiple times. The source of this tension is the Senkaku (as they are known in Japan) or Diaoyu (if you’re in China) Islands – specifically, who owns them.

Some 52 percent of the world’s population lives in cities, a proportion that will only grow throughout the next few decades. Understanding the health challenges facing urban residents is crucial for those who seek to improve human health, especially since many of these challenges differ from those facing inhabitants of rural areas, where global health resources have traditionally been concentrated. At a private meeting on March 4 at the Wilson Center, experts described how factors ranging from climate change and greenhouse gas emissions to reproductive health and rights impact urban health.

As world population pushes towards nine billion by mid-century and millions are elevated to the global middle class every year, demand for water continues to grow as well. More people need more water for drinking and household use, but also for agriculture, mining, energy, and industry. With water often cited as a limit to growth and potential crisis point, the World Resources Institute has released the Aqueduct Water Risk Atlas, which details various types of water stress around the world in impressively detailed fashion.

Dialogue at the Wilson Center tackled demography and the environment last week, interviewing Pulitzer Prize-winning journalist and former Wilson Center public policy scholar Caryle Murphy about her new book, A Kingdom’s Future: Saudi Arabia Through the Eyes of Its Twentysomethings, followed by John Sullivan, director of the Environment and Health and Safety News Division for Bloomberg BNA, on the most important energy and environmental issues of 2013.

The 2009 Copenhagen summit was a watershed moment in the history of climate change negotiations, especially from an Indian perspective. Brazil, South Africa, India, and China – the “BASIC” group – asserted their position, which led to a virtual collapse in talks, ostensibly marking the ascent of the global “south” and relative descent of the “north.”

When Superstorm Sandy slammed into the U.S. East Coast last October, it was the latest in a series of “teachable moments” about our growing vulnerability to climate change.

Across-the-board federal spending cuts that are scheduled to go into effect starting on March 1 are likely to cause further delays to weather and climate satellite programs, and may degrade the government’s ability to issue timely and accurate early warnings of extreme weather and climate events, according to federal officials and atmospheric scientists.
