Higher background water levels mean that deadly and destructive storm surges, such as those associated with Hurricane Katrina, “Superstorm” Sandy, and Hurricane Michael—push farther inland than they once did. View our garbage, recycling, and food & yard waste (compost) services, find the nearest transfer station (dump/landfill) for extra waste, and learn about your collection day. The rising water level is mostly due to a combination of meltwater from glaciers and ice sheets and thermal expansion of seawater as it warms. You can tour the Cedar River Watershed and hike nearby trails. Our large watersheds supply safe and clean drinking water to the greater Seattle area. About half of the measured global sea level rise on Earth is from warming waters and thermal expansion. There are many opportunities for you to become involved and help us keep Seattle great. The map illustrates how climate change could affect the global economy as regions connected by trade are affected by changes in crop yield, droughts, flooding and high temperatures. As global temperatures continue to warm, sea level will continue to rise. By 2005, the glacier had retreated, and the lake had become a small grassland. ... A partial melting of this ice sheet would cause a 1-meter (3-foot) rise. For more detail on the data sources, see the end of the article. Pelto, M. (2019). Now there's a map for that. Learn about current projects in your neighborhood, across the city, and at our drinking water facilities in the region. Seattle Public Utilities maintains 1,600 miles of water pipes. Rep. NOS CO-OPS 083. Maps forecast large areas of Nelson under water from sea-level rise. The higher the sea level, the faster and stronger the return signal is. When water shifts from land to ocean, the increase in mass increases the strength of gravity over oceans by a small amount. The climate projection methodology is described in full in Rasmussen et al. The decadal average loss from glaciers in the World Glacier Monitoring Service’s reference network quintupled over the past few decades, from the equivalent of 6.7 inches (171 millimeters) of liquid water in the 1980s, to 18 inches (460 millimeters) in the 1990s, to 20 inches (-500 millimeters) in the 2000s, to 33 inches (850 millimeters) for 2010-2018. To estimate how much of the observed sea level rise is due to thermal expansion, scientists measure sea surface temperature using moored and drifting buoys, satellites, and water samples collected by ships.

In some ocean basins, sea level has risen 6-8 inches (15-20 centimeters). High-tide flooding is already a serious problem in many coastal communities, and it is only expected to get much worse in the future with continued rising seas. In the United States, the fastest rates of sea level rise are occurring in the Gulf of Mexico from the mouth of the Mississippi westward, followed by the mid-Atlantic. 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. About the data used in the interactive graph. At the same time, the volume of the water itself expands when warmed. Roads, bridges, subways, water supplies, oil and gas wells, power plants, sewage treatment plants, landfills—the list is practically endless—are all at risk from sea level rise. Regional differences exist because of natural variability in the strength of winds and ocean currents, which influence how much and where the deeper layers of the ocean store heat. Sea level is measured by two main methods: tide gauges and satellite altimeters. Find everything to research, obtain permits, install, inspect, or restore pavement for construction involving water lines. Learn about our ongoing maintenance of these pipes and how this work can impact your neighborhood.

Address: Sweet, W.V., Kopp, R.E., Weaver, C.P., Obeysekera, T., Horton, R.M., Thieler, E.R., and Zervas, C. (2017). Observed sea level since the start of the satellite altimeter record in 1993 (black line), plus independent estimates of the different contributions to sea level rise: thermal expansion (red) and added water, mostly due to glacier melt (blue). Water Outages View our current water outage map and read about how you can prepare for planned water outages. This shift of liquid water from land to ocean is largely due to groundwater pumping. Since the 2012 report report, new research has emerged showing that some of the more extreme estimates of how quickly those ice sheets could melt were more plausible than they previously seemed. In no event will The City of Seattle be liable for any loss or damage including without limitation, indirect or consequential loss or damage, or any loss or damage whatsoever arising from loss of data or profits arising out of, or in connection with, the use of any SLR information. Globally, 8 of the world’s 10 largest cities are near a coast, according to the U.N. Atlas of the Oceans. The second mechanism is the melting of ice over land, which then adds water to the ocean. We also offer water service in some surrounding areas. From the 1970s up through the last decade or so, melting and heat expansion were contributing roughly equally to observed sea level rise. The weights for each gauge in the global mean are determined by a cluster analysis that groups gauges from locations where sea level tends to vary in the same way. The pace of global sea level rise more than doubled from 1.4 mm per year throughout most of the twentieth century to 3.6 mm per year from 2006–2015. Climate Resilience Toolkit.). On future pathways with the highest greenhouse gas emissions, sea level rise could be as high as 8.2 feet (2.5 meters) above 2000 levels by 2100. In IPCC Special Report on the Ocean and Cryosphere in a Changing Climate [H.-O. View central estimates. NOAA Tech. As seas rise, saltwater is also contaminating freshwater aquifers, many of which sustain municipal and agricultural water supplies and natural ecosystems. Photo by Flickr user James WIlliamor, via a Creative Commons license. Even if the world follows a low greenhouse gas pathway, global sea level will likely rise at least 12 inches (0.3 meters) above 2000 levels by 2100. We provide construction professionals with guidelines, specifications, and permits to connect to Seattle's water and sewer systems. (2011). (2019). Contribution of Working Group I to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change [Stocker, T.F., D. Qin, G.-K. Plattner, M. Tignor, S.K. Seattle has over 1,200 miles of sewer pipe. Cambridge University Press, Cambridge, United Kingdom and New York, NY, USA. Church, J. The water along Seattle's Puget Sound shoreline has risen by more than 6 inches during the past century. National Oceanic and Atmospheric Administration, National Ocean Service, Silver Spring, MD. We're here to help. To squeeze or stretch the graph in either direction, hold your Shift key down, then click and drag. Global mean sea level has risen about 8–9 inches (21–24 centimeters) since 1880, with about a third of that coming in just the last two and a half decades. Pedersen Glacier, at Aialik Bay in Alaska’s Kenai Mountains, in 1917 (left) and 2005 (right). We partner with schools to promote green practices. Accessed November 18 2019. (2012). Pörtner, D.C.

Bex and P.M. Midgley (eds.)]. In 2012, at the request of the U.S. In many locations along the U.S. coastline, high-tide flooding is now 300% to more than 900% more frequent than it was 50 years ago. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. NOAA Climate.gov graph, adapted from Figure 8 in Sweet et al., 2017. We have programs to help you save on your utility costs. Seattle Public Utilities (SPU) is comprised of three major direct-service providing utilities: the Water Utility, the Drainage and Wastewater Utility, and the Solid Waste Utility. King Tides: Snap the Shore, See the Future A collaboration of NOAA’s Office for Coastal Management and the King Tides Project to help people understand the global impact of sea level rise. Climate change is expected to … Do you have feedback to offer on this or another article?Let us know what you think. Chapter 3: Polar regions. From our watersheds to your streets and parks, we strive to keep Seattle clean and safe. You can see how this process works by building a model using everyday items to demonstrate that water expands when heat energy is added. Naturally occurring ocean climate cycles can also play a role in temporarily masking or enhancing the effects of climate change on sea level rise. The rate of sea level rise is accelerating: it has more than doubled from 0.06 inches (1.4 millimeters) per year throughout most of the twentieth century to 0.14 inches (3.6 millimeters) per year from 2006–2015. Tide gauge stations from around the world have measured the daily high and low tides for more than a century, using a variety of manual and automatic sensors. Temperatures in the upper half of the ocean are measured by a global fleet of aquatic robots. We manage sewer, drainage, and waste collection services for residents and businesses in Seattle. Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas, and a range of other impacts. The non-vegetated vertical accuracy for the project is calculated at 0.172 feet (0.052 meters). Pfeffer, D. Stammer and A.S. Unnikrishnan. Sea-Level Rise ("SLR") information is prepared for use by The City of Seattle for its internal purposes only, and is not designed or intended for use by members of the public. Thermal expansion happens when water gets warmer, which causes the volume of the water to increase. These changes will put pressure on drinking water supplies, food production, property values, and more, in the U.S. and all around the world. All three utilities strive to operate in a cost-effective, innovative and environmentally responsible manner. Global and Regional Sea Level Rise Scenarios for the United States. (2016). The early part of the time series shown in the graph above comes from the sea level group of CSIRO (Commonwealth Scientific and Industrial Research Organisation), Australia's national science agency. Explore information about some of Seattle Public Utilities' completed construction projects, including summaries and documentation. Since the early 1990s, sea level has been measured from space using radar altimeters, which determine the height of the sea surface by me… 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. The pace of sea level rise accelerated beginning in the 1990s, coinciding with acceleration in glacier and ice sheet melting. http://doi.org/10.1007/s10712-011-9119-1, Domingues, R., Goni, G., Baringer, M., & Volkov, D. (2018). Higher sea level also means more frequent high-tide flooding, sometimes called “nuisance flooding” because it isn't generally deadly or dangerous, but it can be disruptive and expensive. In all cases, however, rising sea levels are increasing coastal flood risk. In: Climate Change 2013: The Physical Science Basis. Ice loss from the Greenland Ice Sheet increased seven-fold from 34 billion tons per year between 1992-2001 to 247 billion tons per year between 2012 and 2016. In some ocean basins, sea level has risen as much as 6-8 inches (15-20 centimeters) since the start of the satellite record in 1993. Antarctic ice loss nearly quadrupled from 51 billion tons per year between 1992 and 2001 to 199 billion tons per year from 2012-2016. Tide gauge stations from around the world have measured the daily high and low tides for more than a century, using a variety of manual and automatic sensors. Climate Projections. Hall, R. Horton, K. Knuuti, R. Moss, J. Obeysekera, A. Sallenger, and J. Weiss. Sea level rise and nuisance flood frequency changes around the U.S. NOAA Technical Report NOS CO-OPS 73, 53p. The Intergovernmental Panel on Climate Change (IPCC) stated last month in a special report on the oceans that global average sea levels could rise by up to 1.1m by 2100, in the worst warming scenario. Seattle Public Utilities is investing in our infrastructure to protect public health and the environment and to continue providing essential services to customers. Sea level can rise by two different mechanisms with respect to climate change. The global mean water level in the ocean rose by 0.14 inches (3.6 millimeters) per year from 2006–2015, which was 2.5 times the average rate of 0.06 inches (1.4 millimeters) per year throughout most of the twentieth century. Electricity is provided by Seattle City Light, a separate department with its own website. Construction Resources. Milne, R.S. Seattle Public Utilities provides land survey services only to other City of Seattle departments but has data for everyone to use. Global warming is causing global mean sea level to rise in two ways. In the early 20th century, the glacier met the water and calved icebergs into a marginal lake near the bay. Church, J.A., P.U. ... Sea-Level Rise. NOAA Center for Operational Oceanographic Products and Services. Mailing Address: This is an increase of 0.24 inches (6.1 mm) from 2018. Leuliette, E. (2014). (2013). Allen, J. Boschung, A. Nauels, Y. Xia, V. Bex and P.M. Midgley (eds.)]. Photo by Amy McGovern. Learn about the water system, water quality labs, and metering. Using data from scores of stations around the world, scientists can calculate a global average and adjust it for seasonal differences. Residents and businesses can conserve, reduce waste, and practice sustainability. View our current water outage map and read about how you can prepare for planned water outages. What Caused the Accelerated Sea Level Changes Along the U.S. East Coast During 2010–2015? Large images: 1917 | 2005. Their experts concluded that even with lowest possible greenhouse gas emission pathways, global mean sea level would rise at least 8 inches (0.2 meters) above 1992 levels by 2100. For example, a warmer climate causes more water to evaporate from both land and oceans; in turn, a warmer atmosphere can hold more water – roughly four percent more water for every 1ºF rise in temperature. However, it’s uncertain whether that acceleration will continue, driving faster and faster sea level rise, or whether internal glacier and ice sheet dynamics (not to mention natural climate variability) will lead to “pulses” of accelerated melting interrupted by slowdowns. [Online: https://tidesandcurrents.noaa.gov/publications/techrpt83_Global_and_Regional_SLR_Scenarios_for_the_US_final.pdf], Sweet W. V., J. In 2019, global sea level was 3.4 inches (87.6 mm) above the 1993 average—the highest annual average in the satellite record (1993-present). Also read about what to do if your bill seems too high. Connect with coastal stakeholders across the country through this interactive map, which allows you to identify and share your observations and experiences with sea-level rise impacts along Canada's coastline. From 2018 to 2019, global sea level rose 0.24 inches (6.1 millimeters). Will your city or county be flooded by 2020? [online] http://www.ipcc.ch/pdf/assessment-report/ar5/wg1/WG1AR5_SPM_FINAL.pdf. (The global mean surface air temperature for that period was estimated to be 14°C (57°F), with an uncertainty of several tenths of a degree.) Melt streams on the Greenland Ice Sheet on July 19, 2015. Globally, sea levels have risen about 7 inches since the beginning of the 20th century. Learn about our commitment to equitable service and civic partnerships. Accessed November 2, 2015. Global Sea Level Rise Scenarios for the US National Climate Assessment. Only in Alaska and a few places in the Pacific Northwest are sea levels falling, though that trend will reverse under high greenhouse gas emission pathways. Frightening climate change map shows Scottish cities under water in 2050 The worst affected parts of Scotland are coastal areas, but the North and South Uist in … Discover tips for safer gatherings and ideas for alternative ways to celebrate. In the natural world, rising sea level creates stress on coastal ecosystems that provide recreation, protection from storms, and habitat for fish and wildlife, including commercially valuable fisheries. The interactive map, produced by Climate Central, shows the change in the UK in the next 30 years because of rising sea levels. Coastal flooding is on the rise. (2013). Sign up for a utility discount and get rebates for environmentally friendly practices. In: Climate Change 2013: The Physical Science Basis. Since the early 1990s, sea level has been measured from space using radar altimeters, which determine the height of the sea surface by measuring the return speed and intensity of a radar pulse directed at the ocean. Past and future sea level rise at specific locations on land may be more or less than the global average due to local factors: ground settling, upstream flood control, erosion, regional ocean currents, and whether the land is still rebounding from the compressive weight of Ice Age glaciers. Fires and floods: maps of Europe predict scale of climate catastrophe This article is more than 10 months old Without urgent action, rising sea levels by end of century could leave cities under water Potential Sea-Level Changes. Based on their new scenarios, global sea level is very likely to rise at least 12 inches (0.3 meters) above 2000 levels by 2100 even on a low-emissions pathway. A third, much smaller contributor to sea level rise is a decline in the amount of liquid water on land—aquifers, lakes and reservoirs, rivers, soil moisture. A., and White, N. J. Changes in ocean currents such as the Gulf Stream can also affect sea levels by pushing more water against some coastlines and pulling it away from others, raising or lowering sea levels accordingly. In some ocean basins, sea level has risen as much as 6-8 inches (15-20 centimeters) since the start of the satellite record. The more recent part of the time series is from the University of Hawaii Sea Level Center. By 2005, the glacier had retreated, and the lake had become a small grassland. We manage large, regional watersheds that provide some of the cleanest water in the nation. Sea-Level Rise from the Late 19th to the Early 21st Century. The values are shown as change in sea level in millimeters compared to the 1993-2008 average. Water Outages View our current water outage map and read about how you can prepare for planned water outages. Between 1993 and 2018, mean sea level has risen across most of the world ocean (blue colors). In the early 20th century, the glacier met the water and calved icebergs into a marginal lake near the bay. Photos courtesy of Louis H. Pedersen (1917) and Bruce F. Molina (2005), obtained from the Glacier Photograph Collection, Boulder, Colorado USA: National Snow and Ice Data Center/World Data Center for Glaciology. It is based on a weighted average of 373 global tide gauge records collected by the U.S. National Ocean Service, UHSLC, and partner agencies worldwide. Ice loss from the Greenland and Antarctic Ice Sheets as well as alpine glaciers has accelerated in recent decades. NOAA Climate.gov graphic, adapted from Figure 3.15a in State of the Climate in 2018. Data from the Sea Level Rise Viewer were used to create an interactive map that shows how areas vulnerable to flooding today were often marshlands in 1863. Access manuals, design specifications, and guidelines to meet design and construction rules and requirements, including CAD resources. Climate change impacts the world’s water in complex ways.
