New study triples global estimates of population threatened by sea level rise Map development was also supported in part by U.S. National Science Foundation grant ARC-1203415. private sector and government decision-makers who have more specific More sea level resources from Climate Central Risk Zone Map shows near-term sea level rise and coastal flood threats. of the National Academy of Sciences of the United States of America. There are two timeframes to these maps. 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. 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. 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). Temperatures. Adjust your location and Published 3/12/20. The second timeframe is: When will the sea actually reach the heights shown? Minor carbon cuts. The maps assume no pollution beyond the selected year or temperature. This option corresponds to RCP Support our work.

About | 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. 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). This option corresponds to RCP And the seas will continue to rise. 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. Negative emissions would require engineered active removal of carbon from the atmosphere at a massive scale, likely to be extremely difficult and expensive. 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. It is easier to estimate how much ice will eventually melt from a certain amount of warming, than how quickly it will melt, which involves more unknowns. Stamen Design in San Francisco designed and built the map and mobile tool. without any warranty to their performance, accuracy or suitability for any particular purpose. Tools from NOAA, Climate Central, Information is Beautiful, and EarthTime are helpful for visualizing the effects of sea level rise. 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. Climate Central RCP 8.5 implies we emit a total of 2,430 gigatons of carbon by 2100 (or 3.67 times that weight of CO2). (See privacy and permissions policies below.) 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 Note that in RCP 8.5, annual emissions are still rising in 2100, so locked-in sea levels will continue to increase. The entire Climate Central sea level rise group helped conceive and create this tool, its core design, and the associated materials. Change scenarios. 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. Navigate by typing any city or other place name or postal code through search, or using standard zooming and panning. 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. Use the “+” button to zoom in. The same simple contrast would apply to an ice sculpture in a warm room. 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. Click on the camera icon above the map, or tap on “Download map screenshot” They also reference local high tide lines (mean higher high water, MHHW) based on high-resolution tidal modeling from NOAA, via the tool VDatum. 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. Therefore, this map generally under-portrays, and our analysis underestimates, areas that could be submerged at each locked-in sea level. It also corresponds, in this analysis, to 4.7 meters (15.4 feet) of global sea level rise locked in to someday take place. 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. of the National Academy of Sciences of the United States of America. Since we have already warmed the planet more than 1°C, many feet of Climate Central’s Portfolio Analysis Tool (PAT) estimates future coastal flood threat to Hard Rock Stadium. These notes are intended to help explain the research, the maps, and how to use them. 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. They do not show what sea levels will be in this century (see this This option corresponds to RCP Click on the share icon above the map, or tap on “Share this map” Graphical map tiles are by Stamen Design, under CC BY 3.0. 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. 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. This analysis and the maps do not account for levees and other defenses that have been or might be built. Please consider supporting our nonprofit efforts. However, these maps and the analysis do not account for post-2100 pollution. (In most places, these might translate to a few centimeters or inches per century, but some places, such as southeastern Louisiana in the U.S., are sinking close to ten times faster.). needs. The span from 2-4 °C covers the likely range of possible outcomes from global climate talks at COP21 in Paris. New Coastal Risk Screening Tool Supports Sea Level Rise and Flood Mapping by Year, Water Level, and Elevation Dataset. 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. Limiting warming to 2 °C (3.6 °F) could cut the total population numbers by more than 10 million, and reduce the damage inflicted on many iconic American cities and landmarks. Climate Central’s sea level maps and tools are grounded in peer-reviewed science. window size to get a different image. Coastal flooding is on the rise. 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. Special Thanks. 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. Embed the map. It is not meant as a planning tool or as a prediction for any precise location. Licensing | 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. And compounding this risk, scientists expect roughly 2 to 7 more feet of sea level rise this century — a lot depending upon how much more heat-trapping pollution humanity puts into the sky. Please cite Climate Central in any publication All data and maps are provided “as is” Find out how coastal flood risk events may have an effect on your facilities and investments.

Back to top. Members of the Climate Central staff and board are among the most respected leaders in climate science. This effort is made possible thanks to the many organizations that have supported Climate Central and its sea level program, including the V. Kann Rasmussen Foundation, the Kresge Foundation and the Schmidt Family Foundation. See related content. Which level depends on how much we pollute. utilizing them, include a link to http://sealevel.climatecentral.org/ if map for near-term analysis). Temperatures | Unchecked pollution | Minor cuts | Moderate cuts | Extreme cuts, The sea level we lock in depends on the total amount of carbon we put into the atmosphere. Rising seas dramatically increase the odds of damaging floods from storm surges. 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. 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. PowerPoint and PNG images are taken using your browser's current view. Caribbean islands, plus Guyana and Suriname, use CoastalDEM™ elevation data, a proprietary high-accuracy bare earth elevation dataset developed especially for low-lying coastal areas by Climate Central. Globally, sea levels have risen about 7 inches since the beginning of the 20th century. Building in coastal flood risk zones is outpacing safer development in some states.
