News Brief
Rising Seas Will Cost at Least $400 Billion in the U.S.
Per capita costs would exceed a million dollars in some communities.
The report focuses on construction of seawalls and relies on conservative estimates. For example, it looks only at storm surge from one-year storms, because these are nearly guaranteed to happen annually, rather than at 100-year or 500-year storms. It projects only modest sea-level-rise, assuming some reductions in carbon emissions. “This conservative approach is by design and is intended to shine a light on near-term costs and choices that cannot be avoided,” the report notes.
The expense per capita in many communities will be enormous, contends the report, exceeding $1 million in many areas (the highest estimated cost per capita is $7,155,000 in Junction City, Washington). The authors recommend holding fossil fuel companies accountable for at least some of these expenses.
The full dataset is available, along with rankings of different communities’ projected costs.
