Joseph Nye writes that even at this early stage, there are at least eight lessons— some old, some new— that the world is learning (or relearning) from the war in Ukraine.

Will China succeed in what some call its grand strategy of displacing American power? Whichever scenario emerges also depends on the strategy the US chooses in response, rites Joseph Nye.

Carbon capture, utilization, and storage (CCUS) is very likely to be a key technology for achieving the Biden administration's goal of net-zero greenhouse gas emissions by 2050. But absent regulation requiring its use, CCUS needs to become more economical in order for deployment in the United States to expand significantly.

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

In the wake of a series of damaging cyber intrusions on private businesses controlling critical pieces of U.S. infrastructure, Harvard Kennedy School Senior Lecturer Juliette Kayyem says that countering the growing threat will require erasing the "legal fiction" that cyberattacks are different than physical attacks on American civilians.

This study provides a whole-systems simulation on how to halve global CO2 emissions by 2050, compared to 2010, with an emphasis on technologies and costs, in order to avoid a dangerous increase in the global mean surface temperature by end the of this century.

By investing in the public and private sector research and development in this space, and by fostering a community of researchers, entrepreneurs, and investors literate in CO2 capture opportunities, the United States can be the leader of this new economic sector. It is essential for the Nation to build a vibrant and sustained research and development community spanning the public sector, academic and research domains, and for-profit companies, ensuring world leadership in this new technological domain.

Professor Joseph Aldy says the incoming U.S. administration can breathe new life into global efforts against climate change, but faces daunting political and economic obstacles.

President-elect Joe Biden’s decision to create a new cabinet-level position for climate-related issues — and to choose so prominent a figure as former Secretary of State John Kerry to fill it — demonstrates Biden’s sincerity over putting climate at the very center of U.S. foreign policy. It is easy to understate the importance of this appointment, given the flurry of czars created by most new administrations.

The geopolitical and geo-economic forces wrought by the coronavirus pandemic, as examined previously in this series, are likely to slow the transition to a more sustainable global energy mix. Fortunately, the pandemic has also resulted in governments gaining vastly greater influence over whether this shift stalls or accelerates.
