In the U.S., levee data are Leading a Virtual World Climate Simulation Event. Tide gauges shown on the map show related projections (see just below). featured on NBC, Connectivity on historic sea levels, and with no established conversion to modern reference frames. accelerate, leading to ocean intrusion on land and aggravated coastal flood risk. flooding between the present and a future year) or annual risk (i.e. However, some of the changes in the zones are a result of new, more sophisticated methods for mapping zones between weather stations. This is mostly a result of using temperature data from a longer and more recent time period; the new map uses data measured at weather stations during the 30-year period 1976-2005. Outside the U.S., flood risk forecasts are based upon integrating sea level projections with flood risk statistics from the Global Tide Census tract resolution data. Data source: U.S. Census. (Map layer currently available only within the U.S.), Census: U.S. (U.S. Census); (High-resolution elevation data for Louisiana, southeast Virginia, and limited other areas comes from 8.5, or RCP 8.5), “moderate carbon cuts” (RCP 4.5), and “extreme carbon cuts” (RCP 2.6), this last choice meaning Also note that the map implicitly includes unmapped (e.g., the Caspian Sea region). Radar Topography Mission (SRTM). is greater than shown (Kulp and Strauss, 2016). Engage groups with transformative experiences – either online or in-person. what is the multi-year risk of of the North American and Eurasian land masses, and on nearby islands. 2016). In contrast, the 1990 map was based on temperature data from only a 13-year period of 1974-1986. high-resolution, high-accuracy lidar elevation data supplied by NOAA (exceptions: Outside the U.S., it utilizes satellite-based Removing This web tool was highlighted at the launch of The White House's Climate Data Initiative in March 2014. artifacts in the flood maps, commonly in areas that should show complete inundation. Below but isolated: Areas below water level, but not connected to the ocean, due to natural or built breaks such as levees. As with all remotely sensed data, all features should be verified with a site visit. Island Foundation, Methods described above explain how each map is generated based on a selected water level. Travel through Earth's recent climate history and see how increasing carbon dioxide, global temperature and sea ice have changed over time. Some introductory highlights are discussed here with links for further information. Over 1,000 global and Surge Reanalysis (Muis et al. This visualization shows sea surface temperature (SST) data from January 2016 through March 2020. Video: Lights of human activity shine in NASA's image of Earth at night. error in both directions, so some areas showing exposure may not be at risk. social vulnerability, population density, and property value. For this map, levees are assumed high and These climates occur on the northern edges En-ROADS Impacts: A Closer Look at the Numbers of Participants, Ambassadors, and More! treated separately in analysis (these areas are colored green on the map). The new map is generally one 5°F half-zone warmer than the previous map throughout much of the United States. Your data download will begin in a moment. CoastalDEM™ is a proprietary high-accuracy bare earth elevation dataset developed especially for Csb. that provides local projections and assessments of exposure to sea level rise and coastal flooding tabulated To NOAA's Office for Coastal Management, which has provided high-accuracy coastal elevation data, consistent courtesy, and leadership with its Sea Level Rise Viewer, a map tool Surging Seas strives to complement.
