As our climate changes, “we are vulnerable to unacceptable risks of failures in functionality, durability, and safety,” said Alice C. Hill, former senior director for resiliency policy for the National Security Council, as she launched Resilience Week at the Wilson Center. During the week, members of the UN Resilience Academy joined representatives from the Wilson Center, Stanford Woods Institute for the Environment and the Hoover Institute for in-depth discussions on building global resilience in the face of environmental change. “Resilience is proving necessary to withstand the disruptions to our very interconnected systems,” she said.

Hurricanes Irma and Maria devastated Puerto Rico, leaving many on the island without power, drinking water, or cellular service. Such disasters are not just an issue for the Caribbean, said the Wilson Center’s Roger-Mark De Souza in an interview with WOUB that was last month’s most read story on New Security Beat. All coastal areas of the United States, with their growing populations and vulnerable but valuable infrastructure, should be prepared to face more severe climate-related natural disasters.

To meet the climate challenge, city leaders are committing to ambitious emissions targets, designing decentralized action plans, and sharing lessons in transnational networks. Since growing cities are a large source of global emissions, their efforts could contribute substantially to global climate objectives. As the world’s climate experts gather next week in Bonn, Germany, for the 23rd Conference of the Parties (COP-23), urban initiatives will be a key focal point of the agenda-setting conversation.

Six years of brutal warfare have destroyed basic infrastructure in Yemen, Libya, and Syria.  While U.S. and European governments have been largely preoccupied with providing immediate assistance and dealing with refugees, international humanitarian organizations—such as the International Committee of the Red Cross and Doctors without Borders—are focusing on how to repair, maintain, and safeguard the facilities that provide essential services like clean water, sanitation, and electricity.  Yet these efforts are hindered by lack of resources, protracted violence, and—most insidiously—by the warring parties’ intentional targeting of humanitarian actors and environmental infrastructure. Just as the extensive damage from hurricanes in the Caribbean and southeastern United States has underscored the need for more resilient infrastructure, the wars of the Middle East show that protecting infrastructure is key to protecting civilians caught up in conflict.

With air pollution causing more than one million deaths in 2015 and reducing the lifespan of citizens in northern China by three years, clean energy has become a top priority for China’s leaders. China tops the world in wind and solar power installations and the government plans to invest more than $360 billion through 2020 on renewable energy. But the green energy transition needs more than renewable power generation: Long-distance electricity transmission could play a key role in cleaning up China’s brown skies. Our recent study estimated that transmitting a hybrid of renewable and coal power through 12 new high-voltage transmission lines could prevent 16,000 deaths from air pollution exposure, and avoid 340 million tons of CO₂ emissions in China.

As the climate changes, cities will suffer. “These are important places that have a lot of people, property, and local economies that are going to struggle,” said Jessica Grannis, the adaptation program manager at Georgetown’s Climate Center, at a recent Wilson Center event on the role of subnational decision-makers in achieving international goals.  “The good news is that, here in the United States, many cities are recognizing these threats to their people and populations, and they’re beginning to take action,” said Grannis.

In 2011, a group of Hong Kong water activists and researchers traveled the length of the Dongjiang (East) River, which stretches from northeast Guangdong Province into Hong Kong’s New Territories, to investigate the challenges facing the watershed. The Dongjiang basin, which provides nearly 80 percent of Hong Kong’s water supply, has suffered water shortages due to the region’s increasing urbanization and industrialization. They found unchecked wastewater discharges—from agriculture, poultry farms, chemical plants, tanneries, and even an open-air quartz quarry—were dangerously degrading  water quality.

The 1-2-3 punch of hurricanes Irma, Harvey, and Maria has made it devastatingly clear that extreme weather events can and will destroy families, interrupt livelihoods, and tear apart communities, particularly in coastal and low-lying areas of vulnerable regions like the Caribbean and the United States.
