ResilienceWe need to change how and where we build to be ready for a future of more extreme weather
The human and economic losses resulting from extreme weather events during the last several years vividly demonstrate the U.S. historically shortsighted approach to development. The ill-advised, fast-paced construction of human settlements in low-lying, coastal and riverine environments prone to flooding has long been the American way. From Galveston to Hoboken, we have laid out our grids and thrown up our houses with little regard for the consequences. Storms like Sandy are a harbinger of extreme weather events to come as a result of climate change. Without concerted action, the costs, in lives and property, of future weather events will only multiply. Rather than spending $25 million on PR campaigns to convince ourselves we’re “stronger than the storm,” we should start making choices that prove we’re smarter. For while we can’t say when the next hurricane with the force of Sandy (or even greater force) will batter the Atlantic Coast or when extreme flooding will hit Texas, we do know that there will be a next time. And we’re still fundamentally unprepared for it. We can’t continue to bet against climate change; we’ll lose in the end.

And the consequences can be devastating. Hurricane Sandy, which hit the East Coast in 2012 just one year after Hurricane Irene, another “100-year” storm, “filled up Hoboken like a bathtub.” The storm’s impact all across the eastern seaboard was staggering: 147 people were killed, 650,000 homes were damaged or destroyed, and 8.5 million residences lost power, some for weeks. In the end, the costs of the storm were pegged at over US$60 billion, making Sandy the second costliest natural disaster in US history after Hurricane Katrina in 2005.
Storms like Sandy are a harbinger of extreme weather events to come as a result of climate change. Without concerted action, the costs, in lives and property, of future weather events will only multiply. It’s time we recognize not only that the climate is changing but that the development patterns that have hardly served us well in the past certainly won’t serve us well in the future. Changing course will require a reassessment of risks as they relate not only to how but also to where we build. In our larger, more densely populated regions and cities, massive storm protection projects are both necessary and economically viable, but in many places we would be much better served to move out of harm’s way.
Climate change means more extreme weather events
It’s beyond dispute that the planet is warming. The year 2014 was the warmest on record, and projections suggest that by 2100, average global temperatures could increase by between 2 and 11 Fahrenheit. And with rising temperatures come rising sea levels. Globally, sea level rose seven inches during the twentieth century, and projections for the twenty-first century are alarming, with estimates ranging from between 1 and 4 feet globally.
