Partnership with IDB Expands Risk Finder to Caribbean

Published 11/1/17

November, 2017 Risk Finder is now expanded to include most Caribbean islands, plus Suriname and Guyana, using Climate Central's high-accuracy CoastalDEM elevation data. These additions were made possible async through support and collaboration from the Inter-American Development Bank.  Climate Central's Surging Seas Risk Finder aims to provide citizens, communities and policymakers with easily accessible, science-based, local information to help you understand and respond to the risks of sea level rise and coastal flooding. This interactive toolkit includes maps, local sea level and flood risk projections, and potential impacts for land, population, internet infrastructure, and other variables. It analyzes… More »

Extreme Sea Level Rise Mapped in 3D

Published 4/27/17

April 27, 2017 In January 2017, the National Oceanic and Atmospheric Administration published updated sea level scenarios for the United States. They included a new extreme scenario that would mean roughly 8 feet of global average sea level rise by 2100, but 10-12 feet along almost all U.S. shores outside of Alaska. Scientists consider the scenario unlikely, but increasingly plausible, especially with continued high emissions of greenhouse gases. Yesterday, Climate Central released a suite of new maps, visuals and analyses fleshing out the implications: Read our report, Extreme Sea Level Rise and the Stakes for America Tour our interactive 3D map, using the new… More »

New Animated Map Shows How Warming Could Shrink the World’s Coasts

Published 11/1/16

November 1, 2016 Climate Central has launched its first animated map, Seeing Choices, which allows viewers to see the long-term sea levels locked in by different amounts of carbon pollution, contrasting scenarios of 0°C through 4°C of global warming.  Based on recent scientific research, this global interactive tool builds upon our prior work and aims to focus attention on the urgency of moving away from fossil fuels to protect the stability of the world’s climate. Every fraction of a degree of global warming sets in motion sea level rise that will profoundly threaten coastal cities across the… More »

‘Risk Zone’ Map Redesigned and Expanded Globally

Published 11/8/15

November 8, 2015 By Climate Central Climate Central has launched a redesigned version of its Surging Seas Risk Zone Map, and extended the map from U.S.-only to global coverage. Our goal is to provide a powerful new web tool to boost global understanding and communication of sea level rise and coastal flooding under different carbon emissions scenarios, and to better inform coastal planning and resilience efforts globally.   New Risk Zone Map features include: Ability to explore inundation ​risk ​up to 30 meters (100 feet) high across the world's coastlines Local sea level rise projections at over 1,000 tide gauges on 6 continents… More »

New Report and Maps: Rising Seas Threaten Land Home to Half a Billion

Published 11/2/15

November 8, 2015 By Climate Central Carbon emissions causing 4°C of warming — what business-as-usual points toward today —- could lock in enough sea level rise to submerge land currently home to 470 to 760 million people, with unstoppable rise unfolding over centuries. At the same time, aggressive carbon cuts limiting warming to 2°C could bring the number as low as 130 million people. These are the stakes for global climate talks December in Paris. Our analysis details the implications of different warming scenarios for every coastal nation and megacity on the planet, and our globally searchable… More »
