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 »

‘Mapping Choices’ Launched to Visualize Carbon Choices

Published 10/12/15

In conjunction with new peer-reviewed scientific research led by Climate Central in collaboration with Anders Levermann of the Potsdam Institute of Climate Impact Research, and published Monday ​in the Proceedings of the National Academy of Sciences, Climate Central has launched Mapping Choices, an interactive online map that allows anyone to visually compare the long-term consequences that different carbon choices could lock in. Our goal is to offer a new way to essentially see the future, for every coastal city and ZIP code in the US, and better understand what different emissions or warming levels ultimately mean. The sea level… More »

New Report: Sea Level Rise Threatens Hundreds of U.S. Energy Facilities (PDF) News: Senate Hearing Focuses on Threat of Sea Level Rise Watch: Archived webcast of Senate hearing Read: Ben Strauss' Senate testimony Read: Senate testimony of five witnesses  Description: Coastal energy facilities threatened by sea level rise and coastal flooding. Date: April 19, 2012 Full PDF of Report Summary: Sea level rise from global warming is well on the way to doubling the risk of coastal floods 4 feet or more over high tide by 2030 at locations nationwide. In the lower 48 states, nearly 300 energy facilities stand on land… More »
