Environment & Climate Change

Maintaining bitcoin and other cryptocurrencies causes about 0.3 percent of global CO₂ emissions. That may not sound like a lot, but it’s more than the emissions of Switzerland, Croatia, and Norway combined. As many cryptocurrencies crash and the FTX bankruptcy moves into the litigation stage, regulators are likely to scrutinize the crypto world more than ever before. This presents a perfect opportunity to curb their environmental damage.

The good news is that cryptocurrencies don’t have to be carbon intensive. In fact, some have near-zero emissions. To encourage polluting currencies to reduce their carbon footprint, we need to force buyers to pay for their environmental harms through taxes.

Joseph Nye analyzes why the Cold War metaphor in relation to  the U.S. and China, although convenient, is lazy and potentially dangerous. It obscures and misleads us by underestimating the real challenge we face — and offering ineffective strategies.

Stephen Walt looks back at the Trump administration as four years of big ambitions, a handful of successes—and many more failures. He concludes that it was more than a missed opportunity because Trump's blunders have left the United States in much worse shape than when he took office. 

Ambassador Nicholas Burns speaks about the "devastating portrait" of President Trump's leadership during the COVID-19 pandemic. 

Joseph Nye analyzes Trump's misguided approach to China  and concludes that it could lead the United States to discard its aces of alliances and global institutions or to severely restrict immigration. He advises that since the United States cannot solve problems like pandemics and climate change alone, Americans and its leaders must learn to distinguish power with others from power over others.

This essay makes three arguments. First, the US government will need to establish a coronavirus commission, similar to the 9/11 commission, to determine why, since April 2020, the United States has suffered more coronavirus fatalities than any other country in the world. Second, the COVID-19 pandemic represents a watershed for what will be a major national security theme this century: biological threats, both from naturally occurring pathogens and from synthesized biology. Third, intelligence about globalized challenges, such as pandemics, needs to be dramatically reconceptualized, stripping away outmoded levels of secrecy.

Joseph Nye writes that the world is increasingly obsessed with the ongoing power struggle between the United States and China. But the technology-driven shift of power away from states to transnational actors and global forces brings a new and unfamiliar complexity to global affairs.

Arctic Innovator Jenna Stark recommends closing the crisis-related collaboration gap in the polar region. Greater communication between emergency response specialists is needed both for the Arctic to weather the current coronavirus crisis and also to prepare for and mitigate future disasters, such as assuring food security for remote communities in the event of a wildlife disease outbreak.

Kaveri Iychettira and Afreen Siddiqi explain why computational modelling is a useful tool, especially when stakes are high and resources are constrained, and detail why developing countries should build capacity for it. 

Stephen Walt offers what he considers to be the top five silver linings from the COVID-19 pandemic.
