Direct air capture (DAC) is a type of technology that captures carbon dioxide directly from the air. As the negative impacts of climate change become ever more apparent, governments and private industries have funneled increasing support toward DAC as a critical pathway toward achieving a net-zero future. Although a promising technology, wide-scale deployment of DAC faces several significant challenges.

With the looming threat of increased conflict in Ukraine, businesses around the world should be preparing now, write Paul R. Kolbe, Maria Robson Morrow, and Lauren Zabierek. Corporate security and intelligence teams have said they’re seeing an increase in cyber probes, and the U.S. Cybersecurity and Infrastructure Security Agency and the European Central Bank have both issued warnings about potential Russian cyberattacks. At this point, companies should be taking the following steps: 1) Review business continuity plans; 2) Closely examine supply chains; 3) Actively engage peer networks, vendors, and law enforcement around cyber intrusions; 4) Instill a security mindset in employees; and 5) Make sure corporate intelligence and IT teams are working closely together on solutions.

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.

Richard Revesz, the Lawrence King Professor of Law at New York University and co-founder of the Institute for Policy Integrity, shared his thoughts on how the transition to a new presidential administration later this month will impact U.S. environmental and climate change policy in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” a podcast produced by the Harvard Environmental Economics Program.

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.

For most people, there was nothing to celebrate when the International Monetary Fund downgraded its outlook for global economic growth in June, anticipating a contraction of 4.9% for 2020. Yet for others, such as the small but persistent group of economists and others known as the “degrowth movement,” the Covid-induced economic slowdown has a silver lining.

The search for silver linings to the coronavirus pandemic has come up woefully short. But one hopeful — and much talked of — prospect is that the disruption will accelerate the global shift to a more sustainable energy future.

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.
