Climate impacts are growing more frequent and severe as global temperatures rise. Weather-related disasters have seen a five-fold increase over the past half-century. In many cases, these calamities are already testing the adaptation capabilities of vulnerable communities across the world. If emissions follow the trajectory set by current country targets, the chance of temporarily overshooting the 1.5 °C target in the next five years is 48 percent.

This failure would have implications for the global economy and international security. Yet despite the fact that climate change shapes geopolitics, climate risk itself has rarely been featured in international geopolitics and diplomacy.

Ever since the CNA’s Military Advisory Board—composed of former U.S. military personnel—named climate change as a “threat multiplier” in a 2007 report, the term has gained widespread currency both in environmental and national security circles. It also has propelled the need to assess and address climate-related security risks higher up overall policy agendas.

“One of the challenges of responding to climate risks is that climate’s impacts and how those impacts interact with existing systems on the ground are so varied and specific to a given place,” said Lauren Risi, Director of the Wilson Center’s Environmental Change & Security Program, at a recent PeaceCon conference panel on climate change, violence, and migration in Central America. “But there is also an opportunity in how we respond to develop more agile, just, and sustaining programs and policies that go beyond a singular focus on responding to climate change and instead build the overall resilience of communities.” 

Almost two years after Cyclone Idai hit Mozambique, Zimbabwe, and Malawi, thousands of people remain displaced. At the time, Idai was the most powerful cyclone to hit the Southern Hemisphere in two decades, but it is no longer an anomaly. Worse, the Word Bank reports that climate change can potentially wipe out decades of social and economic progress in the developing world by displacing millions of people, many of whom will be pushed into poverty. Food and water insecurity connected to climate hazards—particularly in places dependent on agriculture—is a major factor which has forced families and whole communities to relocate for safety and subsistence.

The impacts of COVID-19 have shown policymakers that we need to invest in infrastructure and shore up existing systems to ensure that they can withstand changing conditions over time, says Alice Hill, former special assistant to President Barack Obama and current senior fellow at the Council on Foreign Resilience, in this week’s New Security Broadcast. “As we go forward, we need to have resilient systems. But we haven’t done that yet, we’re unprepared.” Hill sat down with Sherri Goodman, Senior Fellow at the Wilson Center’s Environmental Change and Security Program and former U.S. Deputy Undersecretary of Defense, to her new book, The Fight for Climate After COVID-19, and how the response to COVID-19 can inform approaches to building climate resilience. 

“The impacts of displacement present major challenges at every level of decision-making, but the opportunities for interventions that build resilience to climate change, foster social cohesion, and address gender and other disparities—well they’re also very real as well,” said Ambassador Mark Green, President, Director, and CEO of the Wilson Center, during his opening remarks at a recent event hosted by the Wilson Center and Population Institute to explore innovative approaches to addressing the underlying drivers of forced displacement in the Sahel.

Not only is the Sahel highly vulnerable to the impacts of climate change, but it is also one of the regions where climate change is most likely to undermine security and trigger violent conflict. Now more than ever, climate security risks must be effectively integrated into stabilisation and peace operations in order to achieve stability in the region.
