As the world continues to battle the COVID crisis, we must not lose sight of the greatest long-term threat faced by mankind: climate change.

COVID-19 and its even more contagious variants have wrought misery upon our world, inflicting massive loss of life and sickness, widespread disruption of health services, and economic ruin with ensuing social upheaval. There is no silver lining.

We can, however, attempt to extract useful lessons from the strategies and tactics──both successful and unsuccessful──used to battle the contagion to better array our forces against that other pending global catastrophe: climate change.

No country has escaped the setbacks caused by COVID-19, but impacts on low-income countries are proving far worse. The World Bank estimates the pandemic and the actions necessary to contain it will drive 150 million people globally into extreme poverty. Post-pandemic, there will likely be long-term effects. Even with this grim reality, there is hope. Governments and international development organizations have accumulated a wealth of knowledge about what works to reduce poverty and increase economic activity. As the Biden administration and other actors work to build a post-pandemic environment, key lessons can be drawn from this knowledge to inform recovery efforts.

Southeast Asia is at the center of the two major geopolitical challenges of the 21^st century: climate change and the rise of China. As decision-makers across the region grow increasingly concerned about climate change and environmental degradation, as well as the implications of intensifying competition between China and the United States, Washington has an opportunity to strengthen its engagement with Southeast Asia and advance its broader geopolitical objectives.

Chile is on the cusp of a new era. Just as its lithium—a common element of energy storage technology, which is itself a critical component of the clean energy transition—is experiencing a rise in global market demand, Chilean citizens have called for a new constitution.

Rather than delve into issue opinion polling, or assess presidential campaign strategies, political demographers assume that political change is the predictable product of a set of mutually reinforcing social, economic, and demographic transitions, which can be tracked using data. But is this true in a country like the United States that has been in the advanced stages of these development transitions for decades? If these transitions are as important as demographers believe, could their variation among the 50 states explain the outcome of the recent U.S. presidential election? If so, what could they tell us about America’s electoral future?

Climate change will upend the 21^st century world order. It will redefine how we live and work, and change the systems of production, trade, economics, and finance. Even now, in the midst of a global pandemic, it is clear that climate change will be the defining issue of this century. In fact, COVID-19 has only underscored the inadequacy of our responses to global crises and heightened the urgency of this call to action. 21^st century diplomacy will have to raise climate ambition, shape the transformative systems change needed, and promote and facilitate new modes of multilateral collaboration.

The dry season returned to Brazil’s Amazon region in late July—and with it, forest fires, largely human-made. After making substantial progress in reducing deforestation in the 2000s and early 2010s, Brazil has reversed course and deforestation is rising. In the Amazon, this season has been the worst in more than a decade in number of fires, and second worst in terms of total deforestation, according to satellite data from Brazil’s National Institute of Space Research (INPE), which monitors the situation.
