My latest book—States and Nature: The Effects of Climate Change on Security (Cambridge University Press)—has been more than two decades in the making. And as I reflect on that journey, I see significant parallels between my own trajectory and the larger efforts to define and refine thinking about climate security.

The harm that comes to the environment during armed conflict is often permanent, yet the lack of advocates to fight for its protection as they happen creates a deafening stillness. Indeed, this state of affairs has led to the environment to be seen as the “silent victim of war.” Vietnam, Kuwait, Syria, Afghanistan, Ukraine, and several more nations have been permanently damaged due to the destruction of the environment during armed conflict which can persist long after hostilities have ceased.

In Iraq, climate change is adding stress to an already precarious situation. Weak public services,  growing unemployment, fossil fuel-related environmental and health hazards, and other factors have generated high levels of social vulnerability and contributed to recent protests. In the top post for May, Dylan O’Driscoll and Shivan Fazil write about how, against this fragile backdrop, insecurity is heightened by increasingly deadly flash floods and more frequent dust storms that pose a public health threat.

Is a “green resource curse” on its way? Kimberly Thompson, a Senior Advisor for Natural Resources and Conflict and the Industry Lead for Mining at the U.S. Agency for International Development (USAID), says that the current status quo in the green mining industry risks “inadvertently creating the conditions” for it to happen.

The infant formula shortage and the COVID-19 pandemic have added fuel to an already existing fire in maternal mental health in the United States.

As Adrienne Griffen, Executive Director of Maternal Mental Health Leadership Alliance pointed out at a recent event on the COVID-19 pandemic, maternal mental health, and policy solutions, “maternal mental health conditions, including anxiety, depression, and other issues, affect 1 in 5 pregnant or postpartum people [in the U.S.].”

In an increasingly unpredictable world of pandemics, conflict, and disasters, climate change is often at the center of conversations about the instability of global affairs. From California wildfires to droughts across East Africa, the role of climate cannot be ignored in any analysis of global unpredictability. And citizens around the world know it. Growing global public support for governments to aggressively act on climate change has led to an increase in policy action on climate issues.
