Specifically attributing a particular weather event to climate change has been difficult – as one famous analogy goes, it’s like determining which of Mark McGwire’s home runs were because of steroids and which weren’t. But climate attribution science is slowly becoming more accurate and accepted. In “Explaining Extreme Events of 2011 From a Climate Perspective,” a new study appearing in July’s Bulletin of the American Meteorological Society, editors Thomas C. Peterson, Peter A. Stott, and Stephanie Herring provide a review of six extreme weather events from last year and offer “some illustrations of a range of possible methodological approaches” to the process of attribution. Among their conclusions, the editors note that, due to climate change, the extreme heat and drought that suffocated Texas in 2011 was 20 times more likely to occur than 40 years earlier. However, the devastating floods that swept across Thailand last year are blamed on a number of other non-climatic factors.

Bouncing along bad roads in a jeep through central Mongolia, with bright blue skies and high clouds overhead, we drive for miles through a treeless landscape, passing only dry grasslands dotted with cattle and white yurts. But as we head north – myself, two U.S. scientists, and one Mongolian forestry expert – we begin to notice Siberian pine and larch growing on the northern slopes of rolling hills, but not the southern slopes, and at some elevations, but not others. In water-scarce Mongolia, as my travel companion Neil Pederson of Columbia University’s Lamont-Doherty Earth Observatory explained, the precarious growth of trees is limited by temperature and moisture availability; small variations – northern slopes are slightly cooler and wetter – can make all the difference.

In the “first spatially explicit comparison of groundwater use, availability, and environmental flow for aquifers globally,” a new article in Nature finds that the “size of the global groundwater footprint is currently about 3.5 times the actual area of aquifers.” An aquifer’s footprint is the theoretical size it would need to be to sustainably support use at its current rate, so groundwater footprints being much larger than their corresponding aquifers is a sign of overuse.

Climate change “has been thought of in many quarters as something that affects folks ‘over there,’ and not as much domestically, and I think that’s a mistake,” said ECSP’s Geoff Dabelko in a recent podcast with the Zurich-based International Relations and Security Network. “I think folks are coming to a realization that there are very high economic, political, and ultimately security stakes for the United States.”

We live in an era when the pace and scope of global change – including forces such as population growth, resource scarcity, urbanization, migration, and economic development – increasingly impact all of us as individuals, from our health and security to our environment and economic well-being. This complex web of the global and local has led the Wilson Center to create a new initiative focusing on global sustainability and resilience.

Following on the news that long-time ECSP Director Geoff Dabelko is moving on to a well-deserved post directing environmental studies at Ohio University’s Voinovich School of Leadership and Public Affairs, I am thrilled to announce that I will direct a new Wilson Center initiative on global sustainability and resilience, which will combine the ongoing efforts of the Environmental Change and Security Program, Global Health Initiative, China Environment Forum, and Comparative Urban Studies Project. This new initiative will integrate and build upon their already substantial contributions to the field.

There’s been much discussion lately about the “water kit,” a mysterious contraption that a purported Pakistani engineer insists will enable cars to use water as fuel.

Yet missing from this debate is a basic but critical fact: Pakistan is dangerously water-deficient. Per capita availability hovers just above the scarcity threshold of 1,000 cubic meters. In several decades, availability could plummet to 550 cubic meters.

I have a bit of news to share. After 15 years at the Wilson Center, I will be moving back to my home town of Athens, Ohio, next week. This fall I will become a professor at Ohio University’s Voinovich School of Leadership and Public Affairs, where I will serve as director of environmental studies and work in their campus-wide Consortium on Energy, Economics, and the Environment.

I am very pleased that I will continue working as a senior advisor to the Environmental Change and Security Program, as both the university and the Wilson Center are eager for me to stay connected on current projects and foster new collaborations. This new role will certainly evolve over time and I look forward to continuing to work with all of you from this different perch.

“I’m going to talk about religion. But it’s a broad and very delicate subject, so I have to limit myself. Therefore I will limit myself to only talk about the links between religion and sexuality…I will talk on what I remember as the most wonderful – it’s the moment when the young couple whispers, ‘tonight, we are going to make a baby,’” said Hans Rosling, the eclectic Swedish doctor and statistician known for his Gapminder tool, in a TedxSummit presentation in April.
