- Abstract:
- The first months of Donald Trump’s presidency have raised serious concerns about the new administration’s understanding of climate change and the associated security risks. President Trump’s vocal skepticism of climate change and his appointment of several prominent climate deniers to his Cabinet, along with deep proposed budget cuts to government activities aimed at slowing or adapting to climate change, could see the new administration do untold damage to the environment, human health and security, economic development, and international peace and stability. The Trump administration’s disengagement comes at a time when severe weather conditions spurred on by climate change are having devastating effects in the United States and around the world. In California, for example, despite a recent respite, the state’s long-running drought cost the state’s agricultural sector an estimated $2.7 billion in 2015 alone, and the state is expected to experience chronic water shortages in the future.1 In southern Africa, for example, millions are at risk of starvation following a two-year drought and above-average temperatures.2 And in Sri Lanka, the worst drought in 40 years has left more than 1 million people affected by acute water shortages.3 These worrying signs early in the Trump administration contrast sharply with the legacy of former President Barack Obama. Before leaving office, President Obama signed a Presidential Memorandum on Climate Change and National Security designed to elevate and address the national security implications of climate change. Hailed as an historic step, the memorandum directed federal departments and agencies to “ensure that climate change-related impacts are fully considered in the development of national security doctrine, policies, and plans.”4 Released alongside a National Intelligence Council, or NIC, report, “Implications for US National Security of Anticipated Climate Change,” the memorandum reflected the consensus among U.S. national security experts that climate change is a core national security concern and should be addressed as such.5 Indeed, even some within the Trump administration agree with this consensus: Trump’s Secretary of Defense James Mattis, in his written testimony following his confirmation hearing, noted that climate change poses a serious threat to American interests abroad.6 Both Obama’s presidential memorandum and the NIC report argue that extreme and more frequent weather events, droughts, heat waves, rising sea levels, and ocean acidification—all driven or exacerbated by climate change—will increasingly threaten food and water security, energy and transportation infrastructure, and other crucial systems in the decades to come. These disruptions can seriously stress or overwhelm affected governments’ ability to respond to crises, threatening human security and eroding state legitimacy. Deteriorating conditions or severe crises can undermine economic livelihoods and contribute to decisions to migrate. Taken in the aggregate, these stresses can create political instability and amplify conditions that lead to conflict, especially in already fragile or unstable regions.7 And, as many recent crises have demonstrated, instability and violence in one country often do not remain confined solely within that country’s borders. Both reports therefore conclude that it is in the United States’ national interest to try and address the underlying drivers of crises abroad to prevent future instability and avoid more expensive crisis interventions. While the Trump administration’s approach to the issues outlined in the memorandum and the NIC report are shaping up to be hostile, the fact that such challenges exist is unequivocal.8 The administration would do well to heed the advice of climate and national security experts and ensure that the United States continues to address these issues.
