One of the most pressing—and distressing—climate change impacts faced by the world is storm surge, a storm-induced increase in water level exceeding normal, tidal levels. Storm surge is becoming more of a threat to coastal communities due to rising sea levels, since higher sea levels mean higher “normal, tidal levels” before surge even occurs. Affected communities face risks to their homes, infrastructure, and livelihoods, but what can we do about the problem, aside from abandoning coastal communities altogether?
In Episode 20 of ISGP’s “The Forum,” a biweekly audio podcast produced by the Institute on Science for Global Policy, the co-hosts contextualize storm surge, severe storms, and sea level rise in the broader picture of climate change. The New Jersey shore is chosen as a case study since 2012’s Hurricane Sandy devastated the area and raised questions as to how the same coastal communities would cope with similar, future storms exacerbated by greater storm surge.
Episode 20 recaps a debate between Mr. Tom Knutson of the National Oceanic and Atmospheric Administration (NOAA) and scientists, local officials, and community members of Toms River, New Jersey, and the surrounding area. The debate noted that recent hurricanes in the New Jersey coastal area have resulted from warming of the Atlantic Ocean, especially in its northern and tropical regions. The strength of forthcoming hurricanes will be inextricably linked to ocean warming, though trends in U.S. hurricanes making landfall have not been identified. Nonetheless, heightened storm surge associated with rising seas will increase the intensity of hurricanes when they do reach land, and climate models can help us predict this surge before it occurs.
The issues faced by the New Jersey shore are directly applicable to other coastal communities in the United States and abroad. However, in Episode 20 the co-hosts stress that “each location will have to analyze their own risks and make—or not make—their own adaptation decisions.” These decisions exist on a spectrum from more- to less-severe anticipated surge impacts. For instance, individuals anticipating less-severe impacts, whether accurately or inaccurately, can educate themselves about flood insurance options and emergency evacuation routes. Residents expecting more-severe or long-term impacts might even choose to relocate, especially if they will not be able to afford constant rebuilding in the case of more frequent devastation. Full communities, private companies, and emergency response platforms are also beginning, or have begun, planning for surge impacts that have become less theoretical and more a matter of “when.”

To fight illegal coca plantations and conflict actors’ income sources, Colombia’s president wants to loosen the ban on aerial glyphosate spraying. However, considering the dynamics of organised crime, the use of toxic herbicides will not only fail to achieve its aim, it will have many adverse effects for the environment and human health, fundamentally undermining ways to reach peace in the country. International cooperation and national policy-makers need to account for this peace spoiler.
As India grapples with the worsening impacts of climate change, the need to strengthen its adaptation efforts has become more significant than ever. Climate diplomacy and mainstreaming climate adaptation into the most vulnerable sectors could provide some solutions to overcoming barriers, such as the lack of sustainable funding.
“Climate Security risks will materialise in very different ways and forms, whether we talk about Lake Chad or about the Arctic, Bangladesh and the Small Island Developing States,” said the EU’s Ambassador to the United Nations in New York, Joao Vale de Almeida, in his opening remarks. “But for the EU, there is no doubt, as underlined in 2016 in our Global Strategy, and reaffirmed by the 28 Ministers of Foreign Affairs, that climate change is a major threat to the security of the EU and to global peace and security more generally,” he said.
The challenges facing the international community are growing while the willingness to cooperate seems to be waning. Foreign policy must help bridge this gap. One way to accomplish this is by pushing forward a major achievement of multilateralism: the 2030 Agenda and its 17 Sustainable Development Goals. At a side event during the 2019 High-Level Political Forum, diplomats and policy experts discussed the role of foreign policy in the global sustainability architecture.
