Resiliency In The Face Of Stronger Storms
By Josephine Chu
We all remember Superstorm Sandy, especially those of us who live along the East Coast. My parents, who reside on Long Island, were very lucky and did not have any major damage to their home. They did, however, have to live without electricity for two weeks.
Seeing the impact on my parents during this time made me realize just how much we depend on electricity to run the daily tasks in our lives. My parents could cook at home on our gas stove, but without a working refrigerator, they couldn’t store perishables. Long lines at the gas stations meant that even the simple task of driving to buy supplies became difficult. Some of my friends didn’t have running water since there was no electricity to operate the water pumps. These stories made me wonder: will we be prepared if another Sandy hits? Are more Sandys in our future?
While there is uncertainty about the impact of climate change on the frequency of hurricanes, scientists have evidence documenting how climate change will intensify storms. According to the US Global Change Research Program, it is very likely that increased levels of greenhouse gases have contributed to an increase in sea surface temperatures. The intensity of North Atlantic tropical storm activity for most of the mid- to late 20th century has increased, too (see the orange “Power Dissipation Index” line in the figure above). This trend is associated closely with variations in sea surface temperature (see the dashed purple line). As sea surface temperatures are projected to continue increasing in a warming climate, we can expect that warm waters will fuel more intense storms.
Government agencies, including EPA, are working together to implement the Hurricane Sandy Rebuilding Strategy, with the goal of accounting for the impacts of more intense storms. Cities are also taking action; in June 2013, New York City mayor Bloomberg proposed a $20 billion plan of flood barriers and green infrastructure to build a more resilient city.
Check out EPA’s page on adaptation efforts for more information about how we can work together to build climate-resilient communities. With better adaptation efforts, hopefully, my family and other communities can be better prepared for the next storm.
