What Have We Learned from Recent Disasters?

Hurricanes Harvey and Maria. California wildfires. Superstorm Sandy. The great Texas blackout. The list goes on.
These mega-events dramatize the need to improve our disaster response system. The trends are striking: escalating disaster impacts, more disaster clustering, more disaster cascades, and less predictability. We need to up our game. Lisa Grow Sun and I discuss the implications in a new paper, but here are a few of the key takeaways.
Escalating impacts. From 1980 to 2020, there were an average of seven billion-dollar events per year. (Interestingly, nearly half of them were in Texas.) But from 2015-2020, the average was 16 per year. 2020 had a record-breaking 22 billion-dollar events. Why? It's partly higher GDP and population, so more people and wealth are at risk. More people and infrastructure are located in high-risk areas, especially coasts. And over and above those trends, there's climate change — leading to a sharp increase in extreme weather events with more yet to come.
Clustering. As the number of large-scale disasters increases, the odds increase of two or three happening during a short period of time. By the time Hurricane Maria hit Puerto Rico …
In 2017, Puerto Rico was hit hard by two major hurricanes, Irma and Maria. First came Irma, a Category 5 storm that pummeled the island, leaving a trail of destruction. Less than two weeks later came Maria, another Category 5 storm that directly hit the island in what became the worst natural disaster in the U.S. territory's history. The storm moved directly across the island, knocking out electricity and inundating towns with floodwaters and mudslides.
Maria's immediate aftermath was brutal. It included cascading failures of critical infrastructure that threatened systems that people depend on to survive: energy, transportation, communications, water, and wastewater treatment. The storm caused $90 billion in damage to the island, and Puerto Ricans were forced to live without power for 328 days — the longest blackout in U.S. history. The storm also caused an estimated 3,000 deaths, according to an independent study …
June 1 marked the start of hurricane season for the Atlantic Basin. While not welcome, tropical storms, strong winds, and storm surges are an inevitable fact of life for many residents of the Eastern Seaboard and the Gulf Coast. As a new paper from the Center for Progressive Reform explains, with those storms can come preventable toxic flooding with public health consequences that are difficult to predict or control.
In Ernest Hemingway’s 1970 novel, Islands in the Stream, he wrote of his protagonist, Thomas Hudson, “He knew how to plot storms and the precautions that should be taken against them. He knew too what it was to live through a hurricane with the other people of the island and the bond that the hurricane made between all people who had been through it.”
Only Hemingway could romanticize hurricanes. And things have only gotten worse. Last month …
