“Climate change has the potential to be a very important confidence-building measure between the United States and China,” said Sharon Burke, Senior Advisor of the International Security Program and Resource Security Program at New America. “Because no matter what else is happening in our relationship, we can succeed together on climate change.” She spoke at the launch for a project co-led by the Wilson Center’s Environmental Change & Security Program and adelphi, “21st Century Diplomacy: Foreign Policy is Climate Policy.” Hosted as part of the Berlin Climate and Security Conference, the discussion focused on the “climate superpowers” section of the project.

The COVID-19 pandemic could lead to the death of mass transit. Few victims of COVID-19 were infected aboard mass transit, according to recent research. Yet ridership on urban mass transport has fallen sharply during the pandemic. In some places, such as Wuhan, China, the government shut mass transport down. In other places, the public stayed away. For example, New York City’s Metro-North commuter line reported a 95 percent COVID-19-related decrease in riders. Bus systems, which often disproportionally serve poorer riders who cannot work from home, have seen marked but less extreme drops in ridership.  

Fears of Central American caravans and Saharan smugglers keep European and U.S. leaders up at night. Desperate to manage migration, they turn to short-term fixes, which include blocking borders and supporting authoritarian leaders to contain people—their own citizens and others—before they get close to Europe or the United States. This bit of political theater appeals to some, but has limited effects in overall numbers. The long game consists of addressing root causes so people no longer feel compelled to move at all. But this too will do little to prevent migration north. If anything, it will encourage more people to move.

In early January of this year, China’s “National Sword” policy banned imports of non-industrial plastic waste. The ban forces exporting countries to find new dumping grounds for their waste, which is estimated to total nearly 111 million metric tons by 2030. China’s decision has exposed deep structural flaws and interdependencies in the global waste management system. Western countries that have long depended on China to take their garbage are now struggling to deal with mounds of plastic trash, while China lacks the low-priced labor needed to effectively sort and process waste.

Blockchain, the newest technology poised to revolutionize numerous industries, could help decentralize electricity systems across Asia, Europe, Australia and the United States. In Brooklyn, peer-to-peer microgrids allow prosumers—energy consumers who generate small amounts of electricity from renewable sources—to trade energy with other users. Blockchain technology provides distributed ledgers that validate, record, and share each transaction, using smart contracts that automatically execute energy trades when the price and volume of the electricity transaction meet the contracted requirements.

Plastics. From the devastating effects of plastic pollution on our oceans, to the news that plastic bottles likely pollute the drinking water they contain, plastic pollution—the theme of this year’s Earth Day—has been a highly visible issue, and we’ve seen some notable progress on fighting the plastic battle.
