Jerry Theodorou, an insurance expert at the libertarian R Street Institute, said, “The science on the existence of climate change is settled…”

The federal government has no oversight of insurance companies, which are regulated by the states. The Biden administration has used a small Treasury Department agency to highlight climate change and property insurance by issuing reports and collecting insurer data.

But the administration has also contributed to rising insurance costs by moving forward with the federal flood program that Trump postponed as president. The National Flood Insurance Program is projected to increase premiums by thousands of dollars — and possibly cause policyholders to drop coverage — in areas such as the Louisiana coast as it adjusts rates to better reflect climate change and flood risk.

“Where Harris mentions ‘losing their home, having nowhere to go,’ that could refer to folks who don’t have flood insurance,” Theodorou of the R Street Institute said.
