Four dozen Antarctic ice shelves have shrunk by at least 30% since 1997, and 28 of those have lost more than half of their ice in that time, reports a new study that surveyed these crucial “gatekeepers’’ between the frozen continent’s massive glaciers and open ocean.

Methodology and full results
The data used in this analysis is from a research report conducted by Climate Central and Zillow on the 150 largest coastal cities in the U.S. The research report includes various climate pollution scenarios, including “unchecked pollution,” “moderate carbon cuts,” and “deep carbon cuts.” Risk zones are classified as areas with elevations below local projected sea levels as well as areas with elevations below projected annual flood heights. Low-lying areas protected by topography or levees are excluded.
Real estate data from Zillow includes single-family homes, condominiums, and other multi-unit properties, such as duplexes. Buildings zoned for commercial residential use, such as apartment buildings, are not included. “New housing” refers to housing units built in 2010 or later.
