Usually after dinner, Mr. Ma would take off his shirt, shut the door, and begin work making plastic pellets from scrap. But tonight, he sits in his darkened yard staring at two SUV-sized plastic processing machines and a bundle of colorful scrap plastic. No lights are on, no machines grind, and no familiar theme song of CCTV-1 plays in the background. Walking through other villages in Wen’an County, more men meander around their yards filled with the same idle processing machines and mini-mountains of scrap plastic. Most have never studied English, but they are fluent in the language of plastics, sprinkling words like ABS, PP, and PVC into their conversations. They are the owners of small plastic scrap recycling workshops that were once booming—but are now silent.

Since the dawn of the Industrial Revolution, humans have so vastly altered Earth’s systems that we’re now in the midst of what many are calling the Anthropocene Epoch. Human activity has become the dominant influence on climate and the environment, inflicting changes that may persist for millennia. 

Climate change is widely recognised as one of the major forces shaping the future. Climate impacts illustrate in stark clarity how human actions fundamentally affect the basic physical processes of the planet with vast and, in the worst cases, disastrous consequences for communities around the world. Given these profound impacts, climate change is increasingly treated as a security risk. As a changing climate is causing and will continue to cause diverse impacts across the globe, the associated security challenges are multifaceted. They involve human, community, state, and international security risks, and will require responses across all levels of decision-making, from the local to international.

The world’s ocean and cryosphere have been absorbing the heat from climate change for decades, said Intergovernmental Panel on Climate Change (IPCC) Vice Chair Ko Barrett at a recent Wilson Center event on the IPCC’s Special Report on Oceans and Cryosphere. “The consequences for nature and humanity are sweeping and severe,” she said.

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.

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.
