Bloomberg discusses Mapping America’s Underwater Real Estate. What happens to home prices if flood maps start measuring climate change? Millions of Americans are about to find out.

Millions of Americans just woke up in a flood zone that had never before been listed on U.S. government maps.

The new flood-risk data, released Monday by the research and technology nonprofit First Street Foundation, is a virtually unprecedented disclosure of how much damage climate change can be expected to inflict at the level of individual homes.
