According to new report released by the Center for Climate Integrity, coastal communities in the U.S. will need to spend more than $400 billion in order to protect themselves from the threats of rising sea levels. In the latest paper, the researchers claimed that authorities will be required to build 50,000 miles of coastal barriers across 22 different states by next two decades.
During the course of the latest study, researchers relied on the correlations between the sea level rise and expected increment in yearly storms. According to the data, if the sea levels rise quicker than expected, government will be required to spend more to protect coastal areas.
Unsurprisingly, Florida will need to spend over 75 billion to build 9,243 miles of seawalls. Florida is followed by Louisiana, North Carolina, Virginia and Maryland which are expected to spend $38 billion, $34.8 billion, $31 billion and $27 billion respectively.
While the numbers aren’t surprising, the authors of the study asked the bigger question of who will be responsible for the costs of the projects. Most importantly, given most of the companies which are responsible for the climate change continue to profit from their business, it’s their responsibility to pay for the construction according to the authors.
As a result, the researchers urged to take actions regarding upcoming threats of climate changes. They wrote, “The conclusions of the study can provide the basis for an informed discussion about alternative courses of action and additional sources of revenue beyond raising taxes for necessary adaptation projects.”
