Lots of talk around Washington these days of the U.S. intelligence community preparing a National Intelligence Estimate on climate change. Gordon Mitchell at the University of Pittsburgh’s Security Sweep points out that the pending Intelligence Authorization Act for Fiscal Year 2008 (S. 1538) includes specific language calling for the National Intelligence Council to conduct such an estimate. While the bill is in line for debate on the Senate floor, some of you aficionados might like a look at the full text. Section 321 reads:

NATIONAL INTELLIGENCE ESTIMATE ON GLOBAL CLIMATE CHANGE.

(a) Requirement for National Intelligence Estimate-

(1) IN GENERAL- Except as provided in paragraph (2), not later than 270 days after the date of the enactment of this Act, the Director of National Intelligence shall submit to Congress a National Intelligence Estimate (NIE) on the anticipated geopolitical effects of global climate change and the implications of such effects on the national security of the United States.

(2) NOTICE REGARDING SUBMITTAL- If the Director of National Intelligence determines that the National Intelligence Estimate required by paragraph (1) cannot be submitted by the date specified in that paragraph, the Director shall notify Congress and provide–

(A) the reasons that the National Intelligence Estimate cannot be submitted by such date; and

(B) an anticipated date for the submittal of the National Intelligence Estimate.

(b) Content- The Director of National Intelligence shall prepare the National Intelligence Estimate required by this section using the mid-range projections of the fourth assessment report of the Intergovernmental Panel on Climate Change–

(1) to assess the political, social, agricultural, and economic risks during the 30-year period beginning on the date of the enactment of this Act posed by global climate change for countries or regions that are–

(A) of strategic economic or military importance to the United States and at risk of significant impact due to global climate change; or

(B) at significant risk of large-scale humanitarian suffering with cross-border implications as predicted on the basis of the assessments;

(2) to assess other risks posed by global climate change, including increased conflict over resources or between ethnic groups, within countries or transnationally, increased displacement or forced migrations of vulnerable populations due to inundation or other causes, increased food insecurity, and increased risks to human health from infectious disease;

(3) to assess the capabilities of the countries or regions described in subparagraph (A) or (B) of paragraph (1) to respond to adverse impacts caused by global climate change; and

(4) to make recommendations for further assessments of security consequences of global climate change that would improve national security planning.

(c) Coordination- In preparing the National Intelligence Estimate under this section, the Director of National Intelligence shall consult with representatives of the scientific community, including atmospheric and climate studies, security studies, conflict studies, economic assessments, and environmental security studies, the Secretary of Defense, the Secretary of State, the Administrator of the National Oceanographic and Atmospheric Administration, the Administrator of the National Aeronautics and Space Administration, the Administrator of the Environmental Protection Agency, the Secretary of Energy, and the Secretary of Agriculture, and, if appropriate, multilateral institutions and allies of the United States that have conducted significant research on global climate change.

(d) Assistance-

(1) AGENCIES OF THE UNITED STATES- In order to produce the National Intelligence Estimate required by subsection (a), the Director of National Intelligence may request any appropriate assistance from any agency, department, or other entity of the United State Government and such agency, department, or other entity shall provide the assistance requested.

On Friday, October 12, 2007, the Norwegian Nobel Committee chose the UN Intergovernmental Panel on Climate Change (IPCC) and former U.S. Vice President Al Gore to receive the 2007 Nobel Peace Prize for their respective efforts to document and raise awareness of the effects of climate change.

Some observers are perplexed by the Committee’s decision to award a peace prize for work on an environmental issue. The Environmental Change and Security Program (ECSP), however, has long been cognizant of the myriad ways in which the environment is linked to peace and conflict. Climate change is only one of many environmental issues—including water scarcity, pollution, deforestation, and natural resource exploitation—that can affect security.

This is the second time in three years that the Committee has awarded the Peace Prize to an environmentalist. 2004 winner Wangari Maathai and her Green Belt Movement were recognized for their efforts to develop sustainable livelihoods and empower women through tree planting and other environmental activities. In the latest issue of the ECSP Report, Maathai explains the close linkage between good governance, sustainability, and peace: “When we manage our resources sustainably and practice good governance we deliberately and consciously promote cultures of peace, which include the willingness to dialogue and make genuine efforts for healing and reconciliation…Whenever we fail to nurture these three themes, conflict becomes inevitable.”

ECSP Director Geoff Dabelko reflected on the Committee’s selection of Maathai—and its implications for the international community’s notions of peace and security—in several articles on leading environmental blog Gristmill. Dabelko’s words on Maathai’s selection still ring true: “Yet the criticism may miss the point by missing the widespread violence that goes on within states, violence that is not necessarily well-organized or by force of arms. The structural violence of poverty, corruption, and environmental degradation affects literally billions every day. The Nobel Prize rightly stretched the prior confines of the award and called attention to these ‘conflicts.’”

“Energy is a critical, yet hugely neglected, determinant of human health. Health is an important enough aspect of energy policy to deserve a much greater influence on decisions about our future personal, national, and global energy strategies….Energy is as important as any vaccine or medicine. 2 billion people currently lack access to clean energy: they live in energy poverty and insecurity. International institutions, such as the World Bank and WHO, have repeatedly failed to make the connection between energy and health in their country work,” writes Lancet editor Richard Horton in the journal’s September 15, 2007 issue.

A six-article series in The Lancet examines how energy use—or the lack thereof—affects human health. Providing needed data on the health and economic impacts of both energy use and energy scarcity, the series explores one of the many links between environment and human security. The series is available on The Lancet’s website (subscription required).

At a recent conference at the U.S. Army War College in Carlisle, PA, I had the chance to sit down with one of the most influential military voices on environmental security debates, Dr. Kent Hughes Butts. As both a professor of geography and a retired colonel in the U.S. Army, Dr. Butts has been at the center of the U.S. military’s efforts to grapple with the implications of environmental change. I asked Dr. Butts how he saw the field of environmental security (if we can call it a field) evolving over the last two decades.

Egyptians took to the streets to protest water shortages this summer, reports Inter Press Service (IPS), but despite widespread domestic press coverage of the groundbreaking protests and repeated assurances from Egyptian government officials, Egypt seems to have made little progress in resolving its water shortage problems. Even after President Hosni Mubarak and his cabinet announced a plan to invest $180 million in the construction of small water purification centers in areas susceptible to shortages, popular protests began or continued in multiple provinces. Mohamed Nagi, head of the Habi Centre for Environmental Rights in Cairo, told IPS, “The recent demonstrations show that citizens have lost faith in longstanding government promises to provide them with adequate drinking water.”

Indeed, as the University of Maryland’s Ken Conca points out in “The New Face of Water Conflict,” “Amid the talk of looming ‘water wars,’ a less dramatic—but more immediate—link between water and violence is often ignored: the violence engendered by poor governance of water resources.” The IPS article seems to confirm Conca’s assertion that how well water is managed can be as important as how much water is available. According to Nagi, Egypt’s water infrastructure is chronically underfunded and mismanaged. The article also notes that a study by Egypt’s state-run National Research Centre found that 85 percent of Egypt’s total potable water was wasted due to the poor condition of water distribution systems.

Egypt faces persistent water shortages despite the fact that it and Sudan hold absolute rights to use 100 percent of the Nile’s water under agreements signed in 1929 and 1959. The other countries that depend on the Nile—Burundi, Eritrea, Ethiopia, Kenya, Rwanda, Tanzania, Uganda, and the Democratic Republic of the Congo—are poorer and less powerful than Egypt, so their access to water is even more precarious than Egypt’s. For one scholar’s vision of how the 10 countries of the Nile River basin could cooperate around shared water management, see Patricia Kameri-Mbote’s “Water, Conflict, and Cooperation: Lessons from the Nile River Basin.” Kameri-Mbote believes that the combined efforts of local and national civil society groups and the Nile Basin Initiative, a high-level forum that brings together ministers from the Nile basin countries, could lead to more stable, sustainable, and equitable use of the Nile’s water.

“The possibility of a world transformed by climate change is not a science fiction image of a post-apocalyptic society; it is not a road warrior movie. It is happening now. There is another holocaust now in Darfur.” Brad Miller (D-NC), chairman of the Investigations and Oversight Subcommittee of the House Committee on Science and Technology, chose strong words to open the subcommittee’s September 26, 2007, hearing “The National Security Implications of Climate Change.”

The first witness was General Gordon R. Sullivan (USA Ret.), chairman of the CNA Corporation’s Military Advisory Board, which wrote the groundbreaking report National Security and the Threat of Climate Change. Sullivan reminded the congressmen of the potential destabilizing impacts of climate change—reduced access to freshwater, impaired food production, the spread of diseases, land loss due to flooding, and population displacement, among others—and their potential security consequences, which include an elevated risk of state failure, the growth of terrorism, mass migrations leading to regional and global tensions, and conflicts over resources.

China’s geopolitical importance should make it of particular concern to policymakers, said Alexander Lennon, a research fellow at the Center for Strategic and International Studies. According to Lennon, two-thirds of China’s cities are currently experiencing water and food shortages. These environmental issues already cause unrest among the population, and the combined effects of climate change and rapid urbanization could increase tensions. A destabilized China, however, is only one of the various climate-related problems the United States could face in the future. Climate change could also foster terrorism, Lennon said. Rampant poverty, growing economic inequality, state failure, and ethnic tensions form a fertile substrate for terrorist groups.

James Woolsey, vice president of Booz Allen Hamilton and former director of the CIA, argued that the threats posed by climate change and terrorism should not be isolated from one another. Indeed, “terrorists may exploit vulnerabilities in our energy production and distribution or other weaknesses in our infrastructure,” he said. Fuel convoys in Iraq, for instance, are a primary target for insurgents. Woolsey encouraged policymakers to opt for a plan that would reduce both threats simultaneously. His solution: improving U.S. energy efficiency.

As the nation’s largest single consumer of oil (1.8 percent of the U.S. total), the Department of Defense (DoD) is already working on improving energy efficiency, said Kent Butts, director of National Security Issues at the U.S. Army War College’s Center for Strategic Leadership. More generally, he continued, DoD is devoting considerable attention to the destabilizing impacts of climate change, although there is no overarching directive that guides these efforts. The Navy, for instance, is currently analyzing the security implications of shrinking ice sheets in the Arctic.

U.S. Representative Dana Rohrabacher (R-CA) shared his concerns regarding the military’s efforts to increase vehicles’ efficiency. Focusing too much on climate change, he argued, could be harmful to U.S. troops’ security. “If we decide to produce lighter vehicles in order to consume less oil, soldiers will be less protected. Aren’t our troops more important than climate change?” he asked. Sullivan responded that if lighter vehicles were produced, they would be designed so they protected soldiers as well as today’s heavier vehicles do.

Andrew Price-Smith, a professor of political science at Colorado College, emphasized another potential area of impact: global health. He explained that an increase in temperatures and precipitation could favor the proliferation and geographical expansion of infectious diseases such as cholera and malaria. The spread of deadly diseases to new areas could in turn undermine the economy (through absenteeism, increased medical costs, and premature deaths) and foster political instability.

Finally, several representatives shared their skepticism concerning climate change. Reps. Dana Rohrabacher and James Sensenbrenner (R-WI), who said they did not believe human activities have contributed to climate change, argued that the United States should not try to mitigate climate change, but instead try to adapt to it. “Fostering a more robust economy is our strongest defense against climate change,” said Sensenbrenner. “Because it is too late to prevent rising temperatures, the best response is to ensure that our economy is strong enough to adequately respond.” In other words, he was suggesting that we should not try to reduce carbon emissions, because doing so would slow economic growth. He concluded on an optimistic note: “Everyone agrees that the wealthiest countries and individuals will be the least affected by global warming. Putting more people in a position to afford air conditioning will actually save lives.” Needless to say, not everyone in the room shared his view.

Climate change could be to blame for many of the wars in China during the past millennium, says an article published recently in Human Ecology. The study, the first quantitative examination of the link between conflict and temperature changes, is a milestone in climate change research.

David Zhang and co-authors compared the 899 wars that occurred in eastern China between A.D. 1000 and 1911 with climatic data for the same period. They found that warfare frequency in eastern China—particularly in that region’s southern part—correlated strongly with temperature oscillations. Warfare ratios in the cold phases were twice as high as in the warm phases. Furthermore, almost all dynastic changes and warfare peaks coincided with cold phases.

“In general, rebellion was the dominant category of war,” write the authors. “The rebellions were predominantly peasant uprisings induced by famine and heavy taxation, since farmers were always the first to suffer from declining agricultural production.”

The authors surmise that by affecting agriculture, cooler temperatures disrupted food supply, especially in the ecologically vulnerable northern part of eastern China. Food scarcity could have triggered rebellions or forced people to migrate, further exacerbating food shortages in certain areas. Migration could also have generated tension between groups, producing local conflicts—especially when China was populated by nomadic tribes that could move freely. The authors also hypothesize that food scarcity may have encouraged opposing Chinese armies to conduct cross-border raids on each other’s crops. However, additional, more detailed analysis of the pathways leading from cooler temperatures to conflict in eastern China is needed.

It is unclear whether the correlation observed by Zhang in eastern China will hold true for other parts of the world. We should also be careful not to use this one study to draw premature connections to today’s unprecedented climate change. However, we hope additional quantitative studies will be carried out; they would be solid contributions to the research on climate and security, which currently suffers from a scarcity of empirical data.

The President’s Emergency Plan for AIDS Relief (PEPFAR), a $15 billion commitment, is set to expire at the end of fiscal year 2008. This critical boost in U.S. AIDS funding has helped millions of individuals infected with HIV, and in so doing, has improved developing nations’ health and education systems and decreased violence against women. In an original podcast by the Environmental Change and Security Program and the Global Health Initiative, UNAIDS Executive Director Dr. Peter Piot discusses how reauthorizing PEPFAR at increased levels of funding, expanding AIDS prevention programs, and coordinating global efforts to combat HIV/AIDS under U.S. leadership could amplify the effectiveness and sustainability of the global AIDS response.
