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). window size to get a different image. This option corresponds to RCP Effect of Global Warming and Climate … Which level depends on how much we pollute. These are central estimates within wider possible ranges, as are the further estimates in this section below. 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. Download a KML file and open with Google Climate Central’s Portfolio Analysis Tool (PAT) estimates future coastal flood threat to Hard Rock Stadium. Maps assume no further warming after selected temperature. needs. Stamen Design in San Francisco designed and built the map and mobile tool. Global flood layers are available for viewing in Google Earth. 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”). Maps assume no further pollution after selected year. The same simple contrast would apply to an ice sculpture in a warm room. We quantify the increasing chances of coastal flood events for organizations in the public and private sectors. These maps pose this question: which legacy will we choose? (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.). This analysis and the maps do not account for levees and other defenses that have been or might be built. Explore where, when and what could be impacted near you. 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. 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. China further has the most to gain from limiting warming to 2 °C (3.6 °F), which would cut the total to 64 million. Global warming has raised global sea level about 8 inches since 1880, and the rate of rise is accelerating. 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. The first is: When do we pass the point of no return, and lock in the future sea levels shown? Stamen Design in San Francisco designed and built the map and mobile tool 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. Temperatures. 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. Rising seas dramatically increase the odds of damaging floods from storm surges. 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 Climate Central sea level rise group conceived and maintains this tool. of Use. 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. Sea level rise map. ×Sea level maps not available at this latitude due to elevation and coastline data quality challenges. Find out how coastal flood risk events may have an effect on your facilities and investments. All data and maps are provided “as is” This map is paired with a companion report , brief , and interactive tool (scroll to the “Future Flood Risk to Homes” section of the tool after inputting a location name).The integrated project was executed in partnership between Climate Central and Zillow. Other visualizations are based on carbon pathways, as opposed to set temperature increases, and are described just below. via the settings menu. 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. 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. Building in coastal flood risk zones is outpacing safer development in some states. map for near-term analysis). 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. Change scenarios. However, these maps and the analysis do not account for further pollution past 2100 under any of the four carbon pathways considered. Please consider supporting our nonprofit efforts. At the same time, the volume of the water itself expands when warmed. The areas colored blue are the areas below those levels – areas which will eventually be permanently underwater. See related content. 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). About | 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. 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. 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. Globally, sea levels have risen about 7 inches since the beginning of the 20th century. The sea may rise higher still over longer timeframes, but those possibilities are beyond the scope of this analysis. Below are detailed maps from U.S. Tools from NOAA, Climate Central, Information is Beautiful, and EarthTime are helpful for visualizing the effects of sea level rise. Privacy Policy | Map development was also supported in part by U.S. National Science Foundation grant ARC-1203415. via the settings menu. 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. Special Thanks. Minor carbon cuts. 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. via the settings menu. Bathymetry (AusSeabed) Bureau of Meterology: Climate Change RCP 8.5 implies we emit a total of 2,430 gigatons of carbon by 2100 (or 3.67 times that weight of CO2).

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. they are used online, and adhere to our terms of use. 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. 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. 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. 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.

Flood Map shows the map of the area which could get flooded if the water level rises to a particular elevation. Embed the map. These two elements contribute to sea level rise. 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). It is not meant as a planning tool or as a prediction for any precise location. 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. 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. Back to top. Back to top 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. 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. This Climate Central map shows how sea-level rise will cover parts of South Florida, based on the elevation. Please consider supporting our nonprofit efforts. Humanity is currently adding about 10 GtC to the atmosphere annually, a rate that has been increasing almost every year. 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.

The entire Climate Central sea level rise group helped conceive and create this tool, its core design, and the associated materials. Carbon emissions levels would still influence all outcomes. Unchecked pollution. That’s what these maps are about. Lock-In | Timing | Choices | Impacts | Sources | Help | Team | Funding | Legal. 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. 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). Some research has suggested that the West Antarctic Ice Sheet has begun an unstoppable collapse, but the evidence is far from conclusive. utilizing them, include a link to http://sealevel.climatecentral.org/ if Adjust your location and Earth to explore. 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. 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. The entire Climate Central sea level rise group helped conceive and create this tool, its core design, and the associated materials. Climate Central built this screening-level public web tool to help communities, planners, and leaders better understand sea level rise and coastal flood risks. 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. However, these maps and the analysis do not account for post-2100 pollution. These notes are intended to help explain the research, the maps, and how to use them. These are a few of the headlines from the Climate Central-led paper and report behind these maps. Note that in RCP 8.5, annual emissions are still rising in 2100, so locked-in sea levels will continue to increase. Share the map.

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. 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. If collapse has in fact begun, all locked-in sea levels would be higher than shown. These increases threaten an enormous amount of damage. It also corresponds, in this analysis, to 4.7 meters (15.4 feet) of global sea level rise locked in to someday take place. 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.
