How to Defuse Gulf Tensions and Avoid War with Iran

| June 24, 2019

The Trump administration has spent over a year attempting to pressure Iran back to the negotiating table to get a “better deal” than the 2015 nuclear agreement known as the Joint Comprehensive Plan of Action (JCPOA). That strategy has failed. Iran has demonstrated that it is willing to risk war rather than endure the humiliation of negotiating “withsomebodywho hasaknife inhishand.” And PresidentTrump has indicated he doesn’t want to go to war in the Middle East.

Acting on the Climate Crisis: What Must Be Done Now?

As numerous studies have made strikingly clear, climate change is increasing much more rapidly than anticipated and its negative impacts are becoming more and more visible around the world. From the escalating extremity of weather events, severe droughts and wildfires, to melting glaciers, rising sea levels, and disastrous floods, climate change is already harming humans and our ecosystems in a myriad of ways. We asked John P. Holdren, Henry Lee, Robert N. Stavins, Afreen Siddiqi, Kelly Gallagher and Halla Hrund Logadóttir for their thoughts on how best to tackle our climate crisis.

Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. The authors conducted a comprehensive assessment of CBECCS technology for China, with a focus on plant and fuel configurations (e.g., biomass ratios) and economics, as well as CO2 and greenhouse gas emissions and cobenefits for air quality.
