International political boundaries are arbitrary creations. Today’s borders are better described as imaginary lines on maps, rather than hard barriers between states. Often using mountains, rivers, or other geographical landmarks, modern borders are entrenched in historic tradition rather than logic and fact. As a result, today’s international borders are poorly equipped to handle modern challenges, in particular climate change, which has already begun to threaten the most important state resource, fresh water.

The UN Office for Disaster Risk Reduction recently released the fifth edition of the Global Assessment Report on Disaster Risk Reduction (GAR19). The report highlights the increasingly complex interaction between hazards, and provides an update on how risk and risk reduction are understood in practice. GAR19 also highlights how the latest Disaster Risk Reduction (DRR) framework integrates into global goals such as the Paris Agreement and the 2030 Agenda for Sustainable Development. To better understand the scope and significance of this report, New Security Beat sat down with Roger Pulwarty, Senior Scientist at NOAA, and a lead author of the GAR19.

Climate change is a risk, said Maurice Amollo, a Mercy Corps Chief of Party in Nigeria Mercy Corps. “But it is also an opportunity if people come together.” He spoke at a recent USAID Adaptation Community Meeting, “Tackling the threat multiplier: Addressing the role of climate change in conflict dynamics.” The discussion focused on USAID’s Peace III initiative that Amollo and Mercy Corps implemented in the Karamoja region along the borders of Kenya, Ethiopia, Somalia, and Uganda, where climate and conflict shocks are part of daily life for pastoralist ethnic groups. Addressing climate and conflict issues in these regions will require using the environment to build cooperation and peace, said Eliot Levine, the Director of Mercy Corps’ Environment Technical Support Unit.

The Arctic is changing, and it’s changing fast, even faster than models had predicted. The most recent Intergovernmental Panel on Climate Change (IPCC) report found with strong confidence that the Arctic is warming two to three times faster than the global average.

Rising concentrations of heat-trapping greenhouse gases in the atmosphere are reshaping the world from the top down, according to a special report on the world’s oceans and frozen regions from the United Nations climate panel.

Policymakers and emergency managers tend to build a conceptual wall between natural hazards and terrorism. The causes of—and remedies for—these two kinds of disasters are seen as separate and distinct. But, in the era of climate change, the wall between the two is crumbling.

“Today we face two existential threats: nuclear annihilation and catastrophic climate change,” writes Daniel Poneman, former Deputy Secretary of the Department of Energy, in his book, Double Jeopardy: Combating Nuclear Terror and Climate Change. “Both stem from human origins. We need to fight both threats aggressively.” At a recent event hosted by the Wilson Center, Poneman discussed his book. While the dangers of nuclear energy are clear from incidents like Fukushima and Chernobyl, Poneman proposes policies that aim to encourage a safe, non-carbon baseload power that responds to the Intergovernmental Panel on Climate Change (IPCC) 2018 report and keeps our global temperature rise below 2 degrees Celsius above pre-industrial levels, per the 2015 Paris Climate Agreement.

Water security is a pervasive climate issue and one that has increasingly been viewed as a gendered issue. Worldwide, women and girls spend 200 million hours collecting water every day. While doing so, they place themselves at increased risk of assault and become more likely to develop medical issues related to physical labor. They also pay an opportunity cost, as this time could be better spent in school or performing other productive tasks.
