Share the map. 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. Find out how coastal flood risk events may have an effect on your facilities and investments. map for near-term analysis). The same simple contrast would apply to an ice sculpture in a warm room. 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. Climate Central Use our contact form to request more information. These notes are intended to help explain the research, the maps, and how to use them. The Climate Central sea level rise group conceived and maintains this tool. Stamen Design in San Francisco designed and built the map and mobile tool 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. All fields are optional. 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. Interactive global map showing areas threatened by sea level rise and coastal flooding. 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. Rising seas could affect three times more people by 2050 than previously thought, according to new research, threatening to all but erase some of the world’s great coastal cities. Other visualizations are based on carbon pathways, as opposed to set temperature increases, and are described just below. To the many organizations that have financially supported Climate Central and its sea level program, including The Kresge Foundation and The Schmidt Family Foundation. The analysis behind the maps accounts only for warming caused by carbon dioxide, a long-term climate pollutant: in other words, as one example, the 2 °C (3.6 °F) scenario requires enough carbon emissions to cause this warming acting alone. Weather and Climate Impacts by State Map. NOAA's Sea Level Rise map viewer gives users a way to visualize community-level impacts from coastal flooding or sea level rise (up to 10 feet above average high tides). via the settings menu. Projections, analysis, comparisons, and downloadable data and local reportsabout coastal flood and sea level threats to people, property and infrastructure.For cities, counties, states, ZIPs, and much more. window size to get a different image. See maps, images, and video fly-overs of the sea levels that different amounts of warming could lock in. A Climate Central analysis reveals that 89% (217) of 245 cities have fewer cold nights since 1970. Climate Central’s sea level maps and tools are grounded in peer-reviewed science. 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). It also corresponds, in this analysis, to 4.7 meters (15.4 feet) of global sea level rise locked in to someday take place. sea level rise might eventually be “unlocked,” assuming unstoppable ice sheet decay is not already set in motion. Warming of 1.5 °C (2.7 °F) is the preferred goal of many island nations as compared to 2 °C (3.6 °F), and corresponds to 2.9 m (9.5 ft) of locked-in rise. These increases threaten an enormous amount of damage. The Appendix at the end of the downloadable report includes two tables with results for every coastal nation in the world, and affected cities with total population over 1 million. Unchecked pollution. 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. Licensing | 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. Climate Central has created an interactive, zip-searchable map of the U.S. to show the 20 ft of sea level rise that would be locked in by 2°C (3.6°F) of global warming, based on a newly published Science study. There are two timeframes to these maps. The second timeframe is: When will the sea actually reach the heights shown? The entire Climate Central sea level rise group helped conceive and create this tool, its core design, and the associated materials. 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). Therefore, this map generally under-portrays, and our analysis underestimates, areas that could be submerged at each locked-in sea level. Services Climate Central offers coastal area flood and sea level risk assessment services in the U.S. and globally, including infrastructure and portfolio analytics, digital tool-building, and other tailored services and consulting for governments, NGOs, businesses and investors. The maps here do not assume inevitable West Antarctic collapse. Minor carbon cuts. via the settings menu. Since we have already warmed the planet more than 1°C, many feet of No personally identifying information entered in this form will be shared without written permission. These are the four warming levels for which these maps visualize projections of committed sea level rise. Carbon emissions levels would still influence all outcomes. This option corresponds to RCP ×Sea level maps not available at this latitude due to elevation and coastline data quality challenges. 6.0 and implies 1,678 GtC in total carbon pollution by 2100; 2.3 °C (4.1 °F) of warming; and 5.0 meters (16.4 feet) of locked-in global sea level rise. As the world warms, land ice and ice shelves melt, with their water flowing into the global oceans. Under RCP 2.6, annual emissions rapidly peak in 2020, decline sharply to reach zero just after 2080, and become slightly negative after that. 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. Temperatures. Bathymetric map, ocean depth. Sea level rise is one of the best known of climate change’s many dangers. They also reference local high tide lines (mean higher high water, MHHW) based on high-resolution tidal modeling from NOAA, via the tool VDatum. As humanity pollutes the atmosphere with greenhouse gases, the planet warms. This Climate Central map shows how sea-level rise will cover parts of South Florida, based on the elevation. However, these maps and the analysis do not account for further pollution past 2100 under any of the four carbon pathways considered. Some research has suggested that the West Antarctic Ice Sheet has begun an unstoppable collapse, but the evidence is far from conclusive. Support our work. Below are detailed maps from U.S. These maps are based on peer-reviewed scientific research led by Benjamin Strauss and Scott Kulp of Climate Central in collaboration with Anders Levermann of the Potsdam Institute of Climate Impact Research, and published in Proceedings That’s what these maps are about. Please cite Climate Central in any publication Search or navigate our interactive tools above to see maps of areas below different amounts of sea level rise and flooding, down to neighborhood scale, matched with area timelines of risk. Lock-In | Timing | Choices | Impacts | Sources | Help | Team | Funding | Legal. The tool also provides statistics of population, homes and land affected by city, county and state, plus links to factsheets, data downloads, action plans, embeddable widgets, and more. Click on the share icon above the map, or tap on “Share this map” 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. And the seas will continue to rise. Warming of 3 °C (5.4 °F) corresponds roughly to the current sum of “intended nationally determined commitments” Effect of Global Warming and Climate … Graphical map tiles are by Stamen Design, under CC BY 3.0. Building in coastal flood risk zones is outpacing safer development in some states. The multi-part tool provides local sea level rise and flood risk projections, searchable interactive maps, “fast look” community reports, data downloads, and exposure tabulations by zip codes, municipalities, counties, and more. 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. 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 … However, negative emissions also suggest the possibility that some “locked-in” Navigate the map. The span from 2-4 °C covers the likely range of possible outcomes from global climate talks at COP21 in Paris. Photo simulations of how future flooding might impact local landmarks are also provided, as well as data related to water depth, connectivity, flood frequency, socio-economic vulnerability, wetland loss and migration, and mapping … All risks associated with any results, decisions and/or performance of the data made available on this website are borne entirely by the user. of the National Academy of Sciences of the United States of America. Change scenarios. via the settings menu. without any warranty to their performance, accuracy or suitability for any particular purpose. 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. Note that in RCP 8.5, annual emissions are still rising in 2100, so locked-in sea levels will continue to increase. 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. 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. The Supporting Information at the end of the downloadable paper includes 12 tables with detailed and extensive results for each coastal U.S. state and majorly affected city with population exceeding 100,000. Rising seas dramatically increase the odds of damaging floods from storm surges. SRTM data do not cover latitudes farther north than 60 degrees or farther south than 56 degrees, meaning that sparsely populated parts of Arctic Circle nations are not mapped here. Twelve other nations each have more than 10 million people living on land at risk, led by India, Bangladesh, Viet Nam, Indonesia and Japan. 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. See our Privacy Policy for more details. The first is: When do we pass the point of no return, and lock in the future sea levels shown? It is not meant as a planning tool or as a prediction for any precise location. Research. These are a few of the headlines from the Climate Central-led paper and report behind these maps. They do not show what sea levels will be in this century (see this The areas colored blue are the areas below those levels – areas which will eventually be permanently underwater. Maps assume no further pollution after selected year. More sea level resources from Climate Central Risk Zone Map shows near-term sea level rise and coastal flood threats. Climate Central built this screening-level public web tool to help communities, planners, and leaders better understand sea level rise and coastal flood risks. Negative emissions would require engineered active removal of carbon from the atmosphere at a massive scale, likely to be extremely difficult and expensive. However, these maps and the analysis do not account for post-2100 pollution. All data and maps are provided “as is” Technically, this option corresponds to a scientific scenario called RCP 8.5, which carbon pollution has been tracking closely so far. Climate Central is a donor-supported not-for-profit organization dedicated to providing All maps … To explore this sea level projection in a 2D map in U.S. locations, navigate to this page. Then move the water gauge up a foot, or two feet, or nine feet. For more information visit Disclaimer |Terms 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. 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. (See privacy and permissions policies below.) Please consider supporting our nonprofit efforts. 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. 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. Click on the embed icon above the map, or tap on “Embed this scene” New Coastal Risk Screening Tool Supports Sea Level Rise and Flood Mapping by Year, Water Level, and Elevation Dataset. Published 3/12/20. Adjust your location and Click on the “plus” icon above the map, or tap on “See more” 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. CoastalDEM is roughly 30 meters in horizontal resolution. Click on the camera icon above the map, or tap on “Download map screenshot” 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. Maps show sea levels that could lock in this century, and occur as early as 2200. 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. Contact, Sea level rise analysis by Climate Central, New Coastal Risk Screening Tool Supports Sea Level Rise and Flood Mapping by Year, Water Level, and Elevation Dataset, Climate Central’s Portfolio Analysis Tool (PAT) estimates future coastal flood threat to Hard Rock Stadium, New study triples global estimates of population threatened by sea level rise, Ocean at the Door: New Homes and the Rising Sea. Your answers will help us to understand our audience and improve our offerings, and we will respect your privacy. Members of the Climate Central staff and board are among the most respected leaders in climate science. Take a screenshot. Here is a guide to the possibilities that can be explored in these maps via different settings. Explore where, when and what could be impacted near you. These are central estimates within wider possible ranges, as are the further estimates in this section below. A number of pro sports venues in coastal areas could be exposed to flooding from sea level rise, including Citi Field in New York, Oracle Park in San Francisco, Petco Park in San Diego, and MetLife Stadium in East Rutherford, N.J. With Florida’s coastal areas already facing increased flood risk from high tide flooding and extreme rainfall events, Climate Central looked into how sea level rise may affect Miami’s Hard Rock Stadium, this year’s Super Bowl host. Local locked-in sea level rise projections, which the maps show, differ slightly from global ones, because of gravitational and isostatic effects described in the research behind this project. Risk Finder includes projections, analysis, and downloadable graphics and reports for every coastal city, county, and state -- and more -- in the contiguous U.S. If collapse has in fact begun, all locked-in sea levels would be higher than shown. The maps assume no pollution beyond the selected year or temperature. This effort is made possible thanks to the many organizations that have supported Climate Central and its sea level program, including the V.
