storm damage

Winter storms can easily become billion-dollar disasters as the snow piles up on interstates and collapses roofs and power lines. Yet, while canceled flights and business interruptions can’t be avoided, what turns a snowstorm into a disaster often can be. I have worked on engineering strategies to enhance disaster resilience for over three decades and recently wrote a book, “The Blessings of Disaster,” about the gambles humans take with disaster risk. Snowstorms stand out for how preventable much of the damage really is. Stay off the roads The easiest storm costs to avoid involve human behavior, including driving during snowstorms. Successfully plowing the snow off a highway requires repeated passes to prevent snow from accumulating to the point where it piles up faster than it can be removed. However, that simple concept breaks down when an accident blocks the lanes, and traffic – including commerce and emergency vehicles – grinds to a halt. W...

Honolulu has lost more than 5 miles of its famous beaches to sea level rise and storm surges. Sunny-day flooding during high tides makes many city roads impassable, and water mains for the public drinking water system are corroding from saltwater because of sea level rise. The damage has left the city and county spending millions of dollars on repairs and infrastructure to try to adapt to the rising risks. Future costs will almost certainly be higher. More than US$19 billion in property value, at today’s dollars, is at risk by 2100 from projected sea level rise, driven by greenhouse gas emissions largely from the burning of fossil fuels. Elsewhere in Honolulu County, which covers all of Oahu, many coastal communities will be cut off or uninhabitable. Unwilling to have their taxpayers bear the full brunt of these costs, the city and county sued Sunoco LP, Exxon Mobil Corp. and other big oil companies in 2020. Their case – one of more than two dozen involving U.S. ci...

If you look back at the history of Atlantic hurricanes since the late 1800s, it might seem hurricane frequency is on the rise. The year 2020 had the most tropical cyclones in the Atlantic, with 31, and 2021 had the third-highest, after 2005. The past decade saw five of the six most destructive Atlantic hurricanes in modern history. Then a year like 2022 comes along, with no major hurricane landfalls until Fiona and Ian struck in late September. The Atlantic hurricane season, which ended on Nov. 30, had eight hurricanes and 14 named storms. It’s a reminder that small sample sizes can be misleading when assessing trends in hurricane behavior. There is so much natural variability in hurricane behavior year to year and even decade to decade that we need to look much further back in time for the real trends to come clear. Fortunately, hurricanes leave behind telltale evidence that goes back millennia. Two thousand years of this evidence indicates that the Atlantic has experie...
