This installation is a celebration of Indonesia's coral reefs, while also pinpointing the human-caused damage that infects the vibrant systems. “Corals, anemones, sponges and other reef-dwelling invertebrates coalesce into a cyclone-like spiral with colorful healthy corals at the eye of the storm, their tentacles and branches dancing in the current,” explains Courtney Mattison. “Toward the edges and tail of the swirling constellation, corals sicken and bleach, exposing their sterile white skeletons — a specter of what could be lost from climate change. Yet at its heart the reef remains healthy, resilient and harmonious.” more »

n 2020, there were 30 named storms, of which 14 became hurricanes, including seven major hurricanes last year. Major hurricanes are known to carry winds of 111 mph and higher. The season was so active we ran out of the alphabetical list of names and had to borrow some from the Greek alphabet. This year, however, the Greek alphabet will no longer be used partly due to difficulty translating in different languages. Instead, any extra storms will be named through a supplemental names list from the World Meteorological Organization (WMO). Several factors contributed to NOAA’s prediction for an above-normal hurricane season. Among them: predicted warmer-than-average temperatures in the Tropical Atlantic Ocean and Caribbean Sea; weaker tropical Atlantic trade winds; and an enhanced west African monsoon. more »

US economic activity contracted sharply during 2020 as COVID-19 spread and government introduced policies aimed at curbing the virus. Understanding the impact of the pandemic on economic activity as well as the effectiveness and economic impact of health and containment policies has been a major challenge faced by policymakers. The fundamental issue is that economic activity, COVID-19's spread, and health and containment policies are interconnected — they simultaneously influence each other. In a recent working paper, we develop a methodology to investigate the causal linkages among COVID-19's spread, health and containment policies, and economic activity.1 In this two-part essay, we present a nontechnical summary of our approach and main findings. In particular, Part I explains our methods and summarizes how COVID-19 has affected economic activity and government policies. Part II describes the effects of government policies on COVID-19's spread and economic activity. more »
