High mountain regions face grave environmental challenges with climate change impacts already as severe as any place on earth. Temperature increases are expected to be greater at higher altitudes than at sea level, and glaciers and snowfields are retreating in many areas, increasing the risk of catastrophic glacial lake outburst floods, affecting fresh water supplies for hundreds of millions of people, and exacerbating territorial and natural resource disputes.

If Hurricane Sandy was a wake-up call for many in the United States to the kind of extreme weather that climate change is expected to bring, Typhoon Bopha, which struck the Philippines a month later, is a reminder of what makes developing regions even more vulnerable to these changes.

Rich, untapped deposits of gold, iron, copper, lithium, and rare earth minerals have been known in Afghanistan for decades, but recently, extensive reports from the U.S. Department of Defense and U.S. Geological Survey have shed new light on their potential value.

Every year the United Nations convenes diplomats from more than 190 nations to negotiate a climate change treaty, and in many years negotiators go home with little more than the promise of another annual meeting.

The CIA may have shut down its dedicated climate change center earlier this year, but a recently released report sponsored by the intelligence community reaffirms the deep connection between climate change and national security. New threats to U.S. national security – like increased food and water insecurity and more natural disasters requiring humanitarian assistance – have emerged as climate change creates unprecedented changes in the global environment.

The Wilson Center Policy Briefs are a series of short analyses of critical global issues facing the next administration that will run until inauguration day.

We live in a world that is different from that inhabited by our ancestors in many profound ways. Among the most important changes is that, for the first time, almost half of the world’s people live in cities. According to the United Nations, in 2008 the global urban population surpassed half of the world’s population of 6.7 billion compared with 13 percent a century ago and 3 percent a century before that. This trend will require profound changes in the way the U.S. government addresses everything from development policy to international security.

Five hours by truck and mule from the nearest town, a rumbling generator cuts through the silent night to power large spotlights as botanists crouch and kneel on large blue tarps spread across a cow pasture. It’s nearly midnight, and the team works urgently to describe every detail of the dozens of colorful orchids, ferns, and other exotic plants they have collected that day in Las Orquídeas National Park, one of the single most biologically diverse places on the planet.
