There is not 100% confidence in the elevation data and/or mapping process. It is important not to focus on the exact extent of inundation, but rather to examine the level of confidence that the extent of inundation is accurate (see mapping confidence tab).
The four relative sea level rise (RSL) scenarios shown in this tab are derived from the 2022 Sea Level Rise Technical Report using the same methods as the U.S. Army Corps of Engineers Sea Level Change Curve Calculator. These new scenarios were developed by the U.S. Sea Level Rise and Coastal Flood Hazard Scenarios and Tools Interagency Task Force as input into the U.S. Global Change Research Program Sustained Assessment process and, Fifth National Climate Assessment. These RSL scenarios provide an update to the NOAA 2017 scenarios, which were developed as input to the Fourth National Climate Assessment.
Note: We do not show the low scenario, as it is a continuation of the current global trend since the early 1990s and has been determined to have a low probability of occurring by 2100. Furthermore, this scenario would be associated with low levels of risk even if it did occur.
Another important change from the 2017 scenarios is the exclusion of the extreme (2.5 meter) scenario. Based on the most recent scientific understanding, and as discussed in the IPCC AR6, the uncertain physical processes that could lead to much higher increases in sea level are now viewed as less plausible in the coming decades before potentially becoming a factor toward the end of the 21st century. A GMSL increase of 2.5 meters is thus viewed as less plausible and the associated scenario has been removed.
For almost all the scenarios, RSL rise is likely to be greater than the global average in the U.S. Northeast and the western Gulf of Mexico. In intermediate and low scenarios, RSL rise is likely to be less than the global average in much of the Pacific Northwest and Alaska. For high scenarios, RSL rise is likely to be higher than the global average along all U.S. coastlines outside Alaska.
A RSL-change adjustment to the current National Tidal Datum Epoch (1983-2001) will cause a minimal offset that may be needed for some applications. The USACE Sea Level Change Curve Calculator can correct for this offset.
The inundation areas depicted in the Sea Level Rise tab are not as precise as they may appear. There are many unknowns when mapping future conditions, including natural evolution of the coastal landforms (e.g., barrier island overwash and migration), as well as the data used to predict the changes. The presentation of confidence in these maps only represents the known error in the elevation data and tidal corrections.
Blue areas denote a high confidence of inundation, orange areas denote a high degree of uncertainty, and unshaded areas denote a high confidence that these areas will be dry given the chosen water level.
In this application 80% is considered a high degree of confidence such that, for example, the blue areas denote locations that may be correctly mapped as 'inundated' more than 8 out of 10 times. Areas with a high degree of uncertainty represent locations that may be mapped correctly (either as inundated or dry) less than 8 out of 10 times. For a detailed description of the confidence levels and their computation, see the methods document.
Predictions represent the potential distribution of each wetland type (see legend) based on their elevation and how frequently they may be inundated under each scenario. As sea levels increase, some marshes may migrate into neighboring low-lying areas, while other sections of marsh will change type or be lost to open water.
Note: We do not show the low scenario as it is a continuation of the current global trend since the early 1990s and has been determined to have a low probability of occurring by 2100. Furthermore, this scenario would be associated with low levels of risk even if it did occur.
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. By looking at the intersection of potential sea level rise and vulnerable Census tracts, one can get an idea of how vulnerable populations might be affected by sea level rise. Dark red indicates tracts having a high vulnerability, and the lighter reds indicate decreasing vulnerability.
Click on a NOAA tide station icon in the map to see historical inundation events in flood days per year. The flood thresholds used in these plots are derived national flood thresholds from NOAA Technical Report NOS CO-OPS 086: Patterns and Projections of High Tide Flooding Along the U.S. Coastline Using a Common Impact Threshold. The derived thresholds used here provide a national definition of coastal flooding and impacts for quantifying and communicating risk. These thresholds may deviate from NWS impact thresholds which take into account local flood risk and are used to issue NWS coastal flood watches, warnings, and advisories.
The purpose of this map viewer is to provide federal, state, and local coastal resource managers and planners with a preliminary look at sea level rise and coastal flooding impacts. The viewer is a screening-level tool that uses best-available, nationally consistent data sets and analyses. Data and maps provided can be used at several scales to help estimate impacts and prioritize actions for different scenarios.
The establishment of the United Nations High-level Political Forum on Sustainable Development (HLPF) was mandated in 2012 by the outcome document of the United Nations Conference on Sustainable Development (Rio+20), "The Future We Want". The format and organizational aspects of the Forum are outlined in General Assembly resolution 67/290.
The Forum meets annually under the auspices of the Economic and Social Council for eight days, including a three-day ministerial segment and every four years at the level of Heads of State and Government under the auspices of the General Assembly for two days.
The HLPF is the main United Nations platform on sustainable development and it has a central role in the follow-up and review of the 2030 Agenda for Sustainable Development and the Sustainable Development Goals (SDGs) at the global level. General Assembly resolutions 70/299 and 75/290 B provide further guidance on the follow-up and review of the 2030 Agenda and the SDGs.
As stipulated in the 2030 Agenda for Sustainable Development, the HLPF has a central role in the follow-up and review of the 2030 Agenda and its 17 SDGs at the global level, working coherently with the General Assembly, the Economic and Social Council and other relevant organs and forums.
The Forum facilitates the sharing of experiences, including successes, challenges and lessons learned and provides political leadership, guidance and recommendations for follow-up. It promotes system-wide coherence and coordination of sustainable development policies. It ensures that the 2030 Agenda remains relevant and ambitious and focuses on the assessment of progress, achievements and challenges faced by developed and developing countries as well as new and emerging issues. Effective linkages are made with the follow-up and review arrangements of all relevant United Nations conferences and processes, including on least developed countries, small island developing States and landlocked developing countries.
A central feature of the HLPF are the voluntary national reviews (VNRs) that it receives from Member States on their implementation of the 2030 Agenda and the SDGs. Regularly undertaken by both developed and developing countries, the VNRs provide a platform for partnerships, including through the participation of major groups and other relevant stakeholders.
The HLPF also undertakes annual thematic reviews of the SDGs including cross-cutting issues. As decided in General Assembly resolution 75/290 B, for the remainder of the current cycle of the high-level political forum, the themes shall be:
For the remainder of the current cycle of the high-level political forum convened under the auspices of the Economic and Social Council, the sets of Sustainable Development Goals to be reviewed in-depth shall be:
Follow up and review at the HLPF is informed by an annual progress report on the SDGs prepared by the Secretary-General of the United Nations. The most recent report is available here.. The HLPF is also informed by the Global Sustainable Development Report (GSDR), which strengthens the science-policy interface and is issued every four years (E/HLS/2016/1).
The General Assembly in resolution 67/290 decides that all meetings of the Forum shall provide for the full and effective participation of all States Members of the United Nations and States members of specialized agencies.
For further information please see General Assembly resolution 67/290 on the format and organizational aspects of the Forum and resolution 70/299 on the follow-up and review of the 2030 Agenda for Sustainable Development at the global level.
On the High-level Political Forum on Sustainable Development (HLPF), the General Assembly decided in 2016 in its resolution 70/299 to review progress in implementing resolution 70/299 and resolution 67/290 on the format and organizational aspects of the HLPF at its 74th session. The review was to benefit from lessons learned in the first four-year cycle of the forum, including the SDG Summit in September 2019, as well as from other processes under the GA and ECOSOC related to the follow-up and review of the implementation of the 2030 Agenda for Sustainable Development.
During the 74th session of the General Assembly, on 13 January 2020 the President of the GA appointed the Permanent Representative of Benin and the Permanent Representative of Georgia to facilitate the intergovernmental negotiations related to the implementation of resolution 72/305 on ECOSOC strengthening and the HLPF resolutions 67/290 and 70/299.
