New Coastal Risk Screening Tool Supports Sea Level Rise and Flood Mapping by Year, Water Level, and Elevation Dataset

Published 3/12/20

March 12, 2020 Climate Central today announced the release of its global Coastal Risk Screening Tool to generate customizable, localized maps of projected sea level rise and coastal flood risks by year, water level, and elevation Climate Central’s new mapping tool enables users to explore risks over time, for any coastal location in the world, incorporating multiple pollution scenarios, leading sea level rise models, and the most accurate available elevation data available—including Climate Central’s new CoastalDEM® elevation data for areas outside the United States. Coastal Risk Screening Tool users begin their exploration with three map… More »

Climate Central’s Portfolio Analysis Tool (PAT) estimates future coastal flood threat to Hard Rock Stadium

Published 1/30/20

Image: Climate Central/Nickolay Lamm The image above illustrates what Hard Rock Stadium could look like under 1.5 feet of water during a flood event at 6 feet above the local high tide line. The stadium property is relatively flat, with elevations only about 4 to 6 feet above sea level. Water could reach this level through a combination of sea level rise, tide, and storm surge. If emissions continue unabated and sea level rises at a mid-range pace, analysis shows the Miami Gardens area with a 3% risk of experiencing at least one 6 foot or higher flood between today and 2050; that risk jumps to… More »

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 »
