New study triples global estimates of population threatened by sea level rise

Published 10/29/19

October 29, 2019 Climate Central research finds hundreds of millions more people than previously known live on land at risk from coastal flooding linked to climate change; largest vulnerable populations concentrated in Asia By 2050 sea level rise will push average annual coastal floods higher than land now home to 300 million people, according to a Climate Central study published in Nature Communications. And high tide lines could permanently rise above land occupied by some 150 million, including 30 million in China. Without augmented or new coastal defenses, populations in these areas may face regular flooding or permanent inundation within 30 years. These findings are based on… More »

Ocean at the Door: New Homes and the Rising Sea

Published 7/30/19

July 2019 In 2012, Hurricane Sandy slammed into New Jersey, producing a major storm surge and damaging or destroying many thousands of homes. In the years that followed, builders put up new houses and reconstructed damaged ones—in many areas that will be vulnerable to more flooding in the future. The post-Sandy rebuilding was a striking example of a broader pattern. Across the United States, coastal communities have recently built tens of thousands of houses in areas at risk of future flooding driven by sea level rise from climate change. That has put homeowners, renters, and investors in danger of steep… More »

Climate Central Story Featured on Google Earth’s Voyager

Published 9/12/18

September 12, 2018 Google is featuring a Climate Central story on Google Earth’s Voyager website. Sea Level Rise and the Fate of Coastal Cities illustrates long-term scientific projections flowing from different near-term emissions pathways for heat-trapping gases. The story takes viewers on a tour of seven coastal cities across the globe and visualizes future sea-level rise under different future warming scenarios based on peer-reviewed research by Climate Central and collaborators. Carbon emissions leading to 4 degrees Celsius of warming (7.2 degrees Fahrenheit) would lock in enough eventual sea-level rise to submerge land currently home to as many as 760 million people… More »

Sea Level Tools Released in Spanish

Published 7/18/18

July 18, 2018 Detailed information is now available in Spanish for U.S. coastal communities on populations, infrastructure, and property at risk from rising sea levels and coastal floods, through a trio of Climate Central web tools. Hispanic communities are among those particularly affected by rising seas, with more than 280,000 Hispanics in the contiguous United States living on land less than 4 feet above high tide line. 53% percent of this group lives in Florida, including one-third in Miami-Dade County alone. Other highly affected areas include San Mateo County, Cal., Broward County, Fla. and New York, NY. Climate Central’s tools — Risk… More »

Surging Seas Community Rating System Guide Updated

Published 12/14/17

December, 2017 Climate Central identified many ways its web tools could be used to support activities that receive credit/points within FEMA's Community Rating System (CRS) through conversations with local CRS coordinators and implementers, and with FEMA CRS representatives. This guide provides step-by-step instructions on how to access information and downloads from the Surging Seas web tool that could be utilized within specific CRS activities in FEMA’s 2017 CRS Coordinator’s Manual. Climate Central updated its guide to incorporate the 2017 edition of the CRS Coordinator’s Manual which includes more opportunities for users to gain… More »
