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. Maps that compare temperature increases show sea level projections that lock in if and when enough carbon emissions add up to lock in each temperature increase. Type your address in the search bar. However, negative emissions also suggest the possibility that some “locked-in” Potsdam Institute of Climate Impact Research, Proceedings Since we have already warmed the planet more than 1°C, many feet of 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. 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. Coastal flooding is on the rise. Climate Central is a donor-supported not-for-profit organization dedicated to providing This analysis and the maps do not account for levees and other defenses that have been or might be built. Form submitted. These are the four warming levels for which these maps visualize projections of committed sea level rise. Interested in supporting the Program on Sea Level Rise or Climate Central generally? The first is: When do we pass the point of no return, and lock in the future sea levels shown? of the National Academy of Sciences of the United States of America. Weather and Climate Impacts by State Map. 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. 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. 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. 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. The areas colored blue are the areas below those levels – areas which will eventually be permanently underwater. Navigate the map. 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. At the same time, the volume of the water itself expands when warmed. China further has the most to gain from limiting warming to 2 °C (3.6 °F), which would cut the total to 64 million. See our Privacy Policy for more details. 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). 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. Our scientists publish and our journalists report on climate science, energy, sea level rise… Click on the share icon above the map, or tap on “Share this map” Below are detailed maps from U.S. This is essentially the course we are on now. Lock-In | Timing | Choices | Impacts | Sources | Help | Team | Funding | Legal. Why the wide range? Tools from NOAA, Climate Central, Information is Beautiful, and EarthTime are helpful for visualizing the effects of sea level rise. 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 … 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. 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). Change scenarios. Back to top. The Climate Central sea level rise group conceived and maintains this tool. Disclaimer | Under RCP 2.6, annual emissions rapidly peak in 2020, decline sharply to reach zero just after 2080, and become slightly negative after that. See maps, images, and video fly-overs of the sea levels that different amounts of warming could lock in. Support our work. The Social Vulnerability Index , which shows areas of high human vulnerability to hazards, is based on population attributes from Census 2010 (e.g., age and poverty) and the built environment. 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. Find out how coastal flood risk events may have an effect on your facilities and investments. 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. Downloadable data includes local, state and national analysis results, and our methods explain in detail how we generated our data and maps. 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. These notes are intended to help explain the research, the maps, and how to use them. Sea level rise map. Carbon pollution casts a long shadow. Note: We do not provide analysis on individual homes at this time. 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. Terms of Use | To the many organizations that have financially supported Climate Central and its sea level program, including The Kresge Foundation and The Schmidt Family Foundation. Warming of 3 °C (5.4 °F) corresponds roughly to the current sum of “intended nationally determined commitments” These maps contrast different emissions and warming scenarios, over different time frames, which can be accessed and changed by clicking or tapping on the scenario/warming tabs, the settings icon above the map (three horizontal lines with dots), or the settings menu (select “See different futures”). Negative emissions would require engineered active removal of carbon from the atmosphere at a massive scale, likely to be extremely difficult and expensive. Learn more. That’s what these maps are about. This option corresponds to RCP Climate Central’s sea level maps and tools are grounded in peer-reviewed science. Back to top We also provide analysis products for There are two timeframes to these maps. Minor carbon cuts. 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 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. without any warranty to their performance, accuracy or suitability for any particular purpose. Other visualizations are based on carbon pathways, as opposed to set temperature increases, and are described just below. 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. The second timeframe is: When will the sea actually reach the heights shown? Download a KML file and open with Google 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. Building in coastal flood risk zones is outpacing safer development in some states. Maps assume no further warming after selected temperature. The entire Climate Central sea level rise group helped conceive and create this tool, its core design, and the associated materials. Which level depends on how much we pollute. sea level rise might eventually be “unlocked,” assuming unstoppable ice sheet decay is not already set in motion. Twelve other nations each have more than 10 million people living on land at risk, led by India, Bangladesh, Viet Nam, Indonesia and Japan. The entire Climate Central sea level rise group helped conceive and create this tool, its core design, and the associated materials. Effect of Global Warming and Climate … It is not meant as a planning tool or as a prediction for any precise location. These are central estimates within wider possible ranges, as are the further estimates in this section below. This Climate Central map shows how sea-level rise will cover parts of South Florida, based on the elevation. See related content. 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. Research. Interactive global map showing areas threatened by sea level rise and coastal flooding. (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.). Your download will begin momentarily. Climate Central built this screening-level public web tool to help communities, planners, and leaders better understand sea level rise and coastal flood risks. However, these maps and the analysis do not account for further pollution past 2100 under any of the four carbon pathways considered. All fields are optional. Embed the map.

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. 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. Bathymetry (AusSeabed) Bureau of Meterology: Climate Change Stamen Design in San Francisco designed and built the map and mobile tool Here is a guide to the possibilities that can be explored in these maps via different settings. Take a screenshot. The Climate Central sea level rise group conceived and maintains this tool. Use our contact form to request more information. Privacy Policy | Graphical map tiles are by Stamen Design, under CC BY 3.0. 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. Climate Central 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. Temperatures. Map data by OpenStreetMap, under CC BY SA. 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. 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. a wide range of free and accessible analyses and maps to the public. 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. Map development was also supported in part by U.S. National Science Foundation grant ARC-1203415. 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. These are a few of the headlines from the Climate Central-led paper and report behind these maps. Moderate carbon cuts. Global GIS map layers illustrating the extent of sea level rise and coastal flooding Integrates the leading sea level rise science, local flood history, and cutting-edge elevation data Customizable by year, projection type, sea level rise model, pollution scenario, and more Back to top. 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. About | Warming of 2 °C (3.6 °F) is a long-standing international target, and corresponds to what many would consider successful global efforts to control greenhouse gas emissions. Global warming has raised global sea level about 8 inches since 1880, and the rate of rise is accelerating. for reducing emissions, and 6.4 m (21.0 ft) of locked-in global sea level rise. via the settings menu. via the settings menu. RCP 8.5 implies we emit a total of 2,430 gigatons of carbon by 2100 (or 3.67 times that weight of CO2). 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. Global flood layers are available for viewing in Google Earth. 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). They also reference local high tide lines (mean higher high water, MHHW) based on high-resolution tidal modeling from NOAA, via the tool VDatum. 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. Share the map. Hundreds of millions more people than previously estimated live on land at risk from coastal flooding linked to climate change; largest vulnerable populations concentrated in Asia. All maps … Earth to explore. Click on the embed icon above the map, or tap on “Embed this scene” 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. However, these maps and the analysis do not account for post-2100 pollution. A Climate Central analysis reveals that 89% (217) of 245 cities have fewer cold nights since 1970. More sea level resources from Climate Central Risk Zone Map shows near-term sea level rise and coastal flood threats. utilizing them, include a link to http://sealevel.climatecentral.org/ if Click on the camera icon above the map, or tap on “Download map screenshot” Maps show sea levels that could lock in this century, and occur as early as 2200. They do not show what sea levels will be in this century (see this Local projections shown do not factor in the continuation of current land subsidence or uplift. However, these maps and the analysis do not account for post-2100 pollution. 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). These increases threaten an enormous amount of damage. Humanity is currently adding about 10 GtC to the atmosphere annually, a rate that has been increasing almost every year. As humanity pollutes the atmosphere with greenhouse gases, the planet warms. Application of this research to areas outside the U.S. is detailed in the Mapping Choices report. Use the “+” button to zoom in. 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. 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. PowerPoint and PNG images are taken using your browser's current view. 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. 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. Members of the Climate Central staff and board are among the most respected leaders in climate science. 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 … Make a gift online or contact Barbara Charbonnet at 201-321-8301 or by email at barbcharb@climatecentral.org. The maps assume no pollution beyond the selected year or temperature. Risk Finder includes projections, analysis, and downloadable graphics and reports for every coastal city, county, and state -- and more -- in the contiguous U.S. CoastalDEM is roughly 30 meters in horizontal resolution. We quantify the increasing chances of coastal flood events for organizations in the public and private sectors. Adjust your location and ×Sea level maps not available at this latitude due to elevation and coastline data quality challenges. Published 3/12/20. These maps and analysis do not account for post-2100 negative emissions. of Use. This option corresponds to RCP 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. Again, we welcome you to share these materials widely. 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.
