Warming of 3 °C (5.4 °F) corresponds roughly to the current sum of “intended nationally determined commitments” Your download will begin momentarily. Climate Central now offers analysis products for decision-makers who have more specific needs. This option corresponds to RCP 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 … Please cite Climate Central in any publication Lock-In | Timing | Choices | Impacts | Sources | Help | Team | Funding | Legal. Technically, this option corresponds to a scientific scenario called RCP 8.5, which carbon pollution has been tracking closely so far. Therefore, this map generally under-portrays, and our analysis underestimates, areas that could be submerged at each locked-in sea level. China further has the most to gain from limiting warming to 2 °C (3.6 °F), which would cut the total to 64 million. Please consider supporting our nonprofit efforts. There are two timeframes to these maps. Weather and Climate Impacts by State Map. 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 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. CoastalDEM is roughly 30 meters in horizontal resolution. Bathymetry (AusSeabed) Bureau of Meterology: Climate Change 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. They do not show what sea levels will be in this century (see this Global warming has raised global sea level about 8 inches since 1880, and the rate of rise is accelerating. About | via the settings menu. 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. The maps assume no pollution beyond the selected year or temperature. 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. The maps here do not assume inevitable West Antarctic collapse. Map data by OpenStreetMap, under CC BY SA. Special Thanks. These increases threaten an enormous amount of damage. Interactive global map showing areas threatened by sea level rise and coastal flooding. Global flood layers are available for viewing in Google Earth. If collapse has in fact begun, all locked-in sea levels would be higher than shown. 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. Research. 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. of Use. They also reference local high tide lines (mean higher high water, MHHW) based on high-resolution tidal modeling from NOAA, via the tool VDatum. The span from 2-4 °C covers the likely range of possible outcomes from global climate talks at COP21 in Paris. Privacy Policy | Climate Central is a donor-supported not-for-profit organization dedicated to providing As the world warms, land ice and ice shelves melt, with their water flowing into the global oceans. SRTM provides surface elevations, not bare earth elevations, causing it to commonly overestimate elevations, especially in areas with dense and tall buildings or vegetation. Building in coastal flood risk zones is outpacing safer development in some states. Coastal flooding is on the rise. This option corresponds to RCP Here is a guide to the possibilities that can be explored in these maps via different settings. Use the “+” button to zoom in. RCP 8.5 implies we emit a total of 2,430 gigatons of carbon by 2100 (or 3.67 times that weight of CO2). Use our contact form to request more information. Negative emissions would require engineered active removal of carbon from the atmosphere at a massive scale, likely to be extremely difficult and expensive. via the settings menu. window size to get a different image. 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. for reducing emissions, and 6.4 m (21.0 ft) of locked-in global sea level rise. Carbon emissions levels would still influence all outcomes. Carbon pollution casts a long shadow. 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. ×Sea level maps not available at this latitude due to elevation and coastline data quality challenges. 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 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. via the settings menu. However, these maps and the analysis do not account for post-2100 pollution. Members of the Climate Central staff and board are among the most respected leaders in climate science. These are central estimates within wider possible ranges, as are the further estimates in this section below. Please consider supporting our nonprofit efforts. 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. Sea level rise is one of the best known of climate change’s many dangers. Click on the share icon above the map, or tap on “Share this map” This analysis and the maps do not account for levees and other defenses that have been or might be built. 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. Rising seas dramatically increase the odds of damaging floods from storm surges. 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. The entire Climate Central sea level rise group helped conceive and create this tool, its core design, and the associated materials. All maps … These two elements contribute to sea level rise. The Climate Central sea level rise group conceived and maintains this tool. Which level depends on how much we pollute. Climate Central’s Portfolio Analysis Tool (PAT) estimates future coastal flood threat to Hard Rock Stadium. 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. 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). 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. All data and maps are provided “as is” All fields are optional. See related content. Support our work. needs. Application of this research to areas outside the U.S. is detailed in the Mapping Choices report. Learn more. 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. Click on the embed icon above the map, or tap on “Embed this scene” Maps show sea levels that could lock in this century, and occur as early as 2200. 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. 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. Climate Central, which shows accurate risk zone areas in the U.S. as well as detail on the disaster zones and locations. Embed the map. 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.

Climate Central bridges the scientific community and ... Our scientists publish and our journalists report on climate science, energy, sea level rise. We quantify the increasing chances of coastal flood events for organizations in the public and private sectors. 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. That’s what these maps are about. Globally, sea levels have risen about 7 inches since the beginning of the 20th century. 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. 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 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. Since we have already warmed the planet more than 1°C, many feet of 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. Terms of Use | 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. 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. Again, we welcome you to share these materials widely. Unchecked pollution. Climate Central’s sea level maps and tools are grounded in peer-reviewed science. Local projections shown do not factor in the continuation of current land subsidence or uplift. Navigate by typing any city or other place name or postal code through search, or using standard zooming and panning. 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. New Coastal Risk Screening Tool Supports Sea Level Rise and Flood Mapping by Year, Water Level, and Elevation Dataset. 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. 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. 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. Please consider supporting our nonprofit efforts. It also corresponds, in this analysis, to 4.7 meters (15.4 feet) of global sea level rise locked in to someday take place. they are used online, and adhere to our terms of use.
