This is essentially the course we are on now. The Climate Central sea level rise group conceived and maintains this tool. PowerPoint and PNG images are taken using your browser's current view. Technically, this option corresponds to a scientific scenario called RCP 8.5, which carbon pollution has been tracking closely so far. Earth to explore. Maps show local projections that can vary by several feet from the global average due mainly to changing gravity fields as the polar ice sheets lose mass. Sea level rises MAP: Exact locations in the UK that will be wiped out by rising sea levels EXTREME sea level rises are expected to hit by 2050 according to … The answers depend on our carbon choices, and could easily fall within this century for any of the temperature options (see the scientific paper behind these maps and its Supporting Information, plus two efforts that project warming based on “intended nationally determined commitments” for reducing emissions). However, negative emissions also suggest the possibility that some “locked-in” Use the “+” button to zoom in. Click on the embed icon above the map, or tap on “Embed this scene” Global warming has raised global sea level about 8 inches since 1880, and the rate of rise is accelerating. The answer could be sooner than 200 years from now (see Table 1 in this scientific paper), or as long as 2,000 years (see this paper). Maps that compare carbon scenarios show long-term sea level projections based on different pollution pathways through 2100 (default), 2050, or 2015 (historic pollution), depending on the settings chosen. Sea level projections are based on the expansion of ocean water as it warms; melting glaciers and ice caps; and the decay of Greenland and Antarctic ice sheets. This option corresponds to RCP Terms of Use | Here is a guide to the possibilities that can be explored in these maps via different settings. This Climate Central map shows how sea-level rise will cover parts of South Florida, based on the elevation. There are two timeframes to these maps. They do not show what sea levels will be in this century (see this To the many organizations that have financially supported Climate Central and its sea level program, including The Kresge Foundation and The Schmidt Family Foundation. Other visualizations are based on carbon pathways, as opposed to set temperature increases, and are described just below. Special Thanks. a wide range of free and accessible analyses and maps to the public. At the same time, the volume of the water itself expands when warmed. The first is: When do we pass the point of no return, and lock in the future sea levels shown? of Use. The map for other areas utilizes elevation data on a roughly 300-foot (90-meter) horizontal resolution grid derived from NASA’s Shuttle Radar Topography Mission (SRTM). Within the United States, these maps are based primarily on high quality lidar bare earth elevation data curated by NOAA, with roughly 5-meter (16-foot) horizontal resolution and a vertical accuracy (root mean square error) generally within 15 centimeters (6 inches). private sector and government decision-makers who have more specific A Climate Central analysis finds the odds of “century” or worse floods occurring by 2030 are on track to double or more, over widespread areas of the U.S. Effect of Global Warming and Climate … Disclaimer | However, these maps and the analysis do not account for further pollution past 2100 under any of the four carbon pathways considered. Sea level rise map. Flood Map shows the map of the area which could get flooded if the water level rises to a particular elevation. Licensing | Embed the map. Please consider supporting our nonprofit efforts. Maps assume no further pollution after selected year. These are a few of the headlines from the Climate Central-led paper and report behind these maps. Why the wide range? That corresponds to 3.3 °C (5.9 °F) of eventual warming, and 7.1 meters (23.3 feet) of global sea level rise locked in to someday take place. Carbon emissions causing 4 °C (7.2 °F) of warming—what business-as-usual points toward today—could lock in 6.9 to 10.8 meters (23 to 35 feet) of global sea level rise, enough to submerge land currently home to 470 to 760 million people. 4.5 and implies 1,266 GtC in total carbon pollution by 2100; 1.7 °C (3.1 °F) of warming; and 2.6 meters (11.8 feet) of locked-in global sea level rise. Coastal flooding is on the rise. (See privacy and permissions policies below.)

However, these maps and the analysis do not account for post-2100 pollution. These are central estimates within wider possible ranges, as are the further estimates in this section below. ×Sea level maps not available at this latitude due to elevation and coastline data quality challenges. This option corresponds to RCP Extreme carbon cuts. 2.6 and implies 840 GtC in net total carbon pollution by 2100; 1.1 °C (2.0 °F) of warming; and 2.4 meters (7.9 feet) of locked-in global sea level rise. Click on the heart icon above the map, or tap on “Support our work” Graphical map tiles are by Stamen Design, under CC BY 3.0. Stamen Design in San Francisco designed and built the map and mobile tool. We quantify the increasing chances of coastal flood events for organizations in the public and private sectors. Note: We do not provide analysis on individual homes at this time. The second timeframe is: When will the sea actually reach the heights shown? Back to top Please consider supporting our nonprofit efforts. The maps here do not assume inevitable West Antarctic collapse. See related content. Reading Sea level timing is critical for a clear understanding of when the sea level rise shown on these maps could occur in the future. Since we have already warmed the planet more than 1°C, many feet of New Coastal Risk Screening Tool Supports Sea Level Rise and Flood Mapping by Year, Water Level, and Elevation Dataset. Find out how coastal flood risk events may have an effect on your facilities and investments. Surging Seas maps, graphics and information are backed by scientifically peer-reviewed Climate Central research papers.National and state reports and fact sheets provide background and translate our research for more general audiences. Sea level rise is one of the best known of climate change’s many dangers. However, these maps and the analysis do not account for post-2100 pollution. Interactive global map showing areas threatened by sea level rise and coastal flooding. Click on the “plus” icon above the map, or tap on “See more” Published 1/30/20. What they do show are scientific projections, taken from this paper, of the different post-2100 sea levels that could lock in this century, depending upon the carbon pathway we select. See our Privacy Policy for more details. Some research has suggested that the West Antarctic Ice Sheet has begun an unstoppable collapse, but the evidence is far from conclusive. By overlaying social and economic data on a map that depicts sea level rise, a community can see the potential impact that sea level rise can have on vulnerable people and businesses.

Benjamin Strauss and Scott Kulp of Climate Central led and conducted the research behind this project, in collaboration with Anders Levermann of the Potsdam Institute of Climate Impact Research. It is expected to persist in the atmosphere long enough to prolong temperature increases for hundreds and thousands of years, long after we stop burning fossil fuels or clearing forest. China, the world’s leading carbon emitter, also leads in coastal risk, with 145 million people living on land ultimately threatened by rising seas if emission levels are not reduced. Climate Central’s sea level maps and tools are grounded in peer-reviewed science. Explore where, when and what could be impacted near you. The entire Climate Central sea level rise group helped conceive and create this tool, its core design, and the associated materials. map for near-term analysis). As one indicator suggestive of quality, our analysis of the U.S. based on SRTM elevation data and the global MHHW grid—plus a global population data source—underestimates exposure in the U.S. by 18% after 4 °C of warming, and by 36% after 2 °C of warming, as compared to our analysis based on lidar, VDatum, and U.S. Census data. Explore where, when and what could be impacted near you. Members of the Climate Central staff and board are among the most respected leaders in climate science. of the National Academy of Sciences of the United States of America. As humanity pollutes the atmosphere with greenhouse gases, the planet warms. Across the country, nearly 5 million people live in 2.6 million homes at less than 4 feet above high tide — a level lower than the century flood line for most locations analyzed. they are used online, and adhere to our terms of use. Building in coastal flood risk zones is outpacing safer development in some states. Temperatures. via the settings menu. Stamen Design in San Francisco designed and built the map and mobile tool New study triples global estimates of population threatened by sea level rise Digital Earth Australia: Intertidal Extents Model and High and Low Tide Composites ; NationalMap – view & access Digital Earth Australia Data ; Relevant Links. Risk Finder includes projections, analysis, and downloadable graphics and reports for every coastal city, county, and state -- and more -- in the contiguous U.S. The purpose of this web tool is to provide a picture of post-2100 sea level rise threatened by different levels of carbon pollution, in order to inform public and policy dialogues about energy and climate. Under RCP 4.5, annual emissions peak in 2040 and then decrease, stabilizing at roughly half of current levels, so locked-in sea levels will continue to modestly increase. For more information visit Disclaimer |Terms Warming of 4 °C (7.2 °F) is close to our current path, would represent a breakdown in efforts, and corresponds to 8.9 m (29.2 ft) of locked-in global sea level rise. window size to get a different image. If you'd like it to show another data layer, or a different place, just close this and change the big version to how you want it, then hit EMBED THIS MAP again. Under RCP 6.0, annual emissions peak in 2060 and then decrease, but remain above current levels through 2100, so locked-in sea levels will continue to increase. Application of this research to areas outside the U.S. is detailed in the Mapping Choices report. The historical scenario assumes we will be at 560 GtC by the end of 2015, which matches to 0.7 °C (1.4 °F) of warming and 1.6 meters (5.2 feet) of locked-in global sea level rise. Again, we welcome you to share these materials widely. Carbon pollution casts a long shadow. Aggressive carbon cuts resulting in 2 °C (3.6 °F) warming, the well-established international target, could bring the numbers as low as 3.0 meters (10 feet) and 130 million people. Make a gift online or contact Barbara Charbonnet at 201-321-8301 or by email at barbcharb@climatecentral.org. Climate Central Then move the water gauge up a foot, or two feet, or nine feet. Moderate carbon cuts. The map outside the U.S. (and for Alaska) also utilizes a different source for MHHW, and a global grid for MHHW provided by Mark Merrifield of the University of Hawaii, Manoa, Hawaii. Climate Central built Surging Seas Risk Finder as a free web tool to help U.S. communities, planners and leaders better understand sea level rise and coastal flood risks. Our analysis found most of the stadium property faces exposure to annual flood risk by 2070, if emissions of heat-trapping gases continue to grow unchecked⁠⁠. If collapse has in fact begun, all locked-in sea levels would be higher than shown. Weather and Climate Impacts by State Map.
