Consider a water cycle diagram, like the one below; global warming is altering nearly every stage in the diagram. Scientists account for these types of changes by measuring sea level change … 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. The higher worst-case scenario—which is extremely unlikely, but can’t be ruled out—is largely due to new observations and modeling on ice loss from Antarctica and Greenland. 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. 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. We manage sewer, drainage, and waste collection services for residents and businesses in Seattle. (2011). Will your city or county be flooded by 2020?

Do you have feedback to offer on this or another article?Let us know what you think. Clark, A. Cazenave, J.M. Rates of local sea level (dots) can be amplified by geological processes like ground settling or offset by processes like the centuries-long rebound of land masses from the loss of ice age glaciers. Sea Level Change. Phone: (206) 684-3000. The base digital elevation model (DEM) used in the analysis was produced using data from the 2016 regional LiDAR project by King County & the Puget Sound LiDAR Consortium. In the early 20th century, the glacier met the water and calved icebergs into a marginal lake near the bay. For the safest holidays - EVERYONE should avoid travel and only gather with household members to prevent the further spread of COVID-19 in our region. In the United States, almost 40 percent of the population lives in relatively high population-density coastal areas, where sea level plays a role in flooding, shoreline erosion, and hazards from storms. On the bright side, if future energy choices keep us on one the three lowest pathways, Alaska and the Pacific Northwest are likely to experience local sea level rise that is less than the global average. Learn about the water system, water quality labs, and metering. Explore the programs we offer for you to learn about the environment and get involved. The second mechanism is the melting of ice over land, which then adds water to the ocean. 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 … Global and Regional Sea Level Rise Scenarios for the United States. In 2019, global mean sea level was 3.4 inches (87.6 millimeters) above the 1993 average—the highest annual average in the satellite record (1993-present). ... A partial melting of this ice sheet would cause a 1-meter (3-foot) rise. 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. 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. http://www.star.nesdis.noaa.gov/sod/lsa/SeaLevelRise/documents/NOAA_NESD... https://tidesandcurrents.noaa.gov/sltrends/, http://cpo.noaa.gov/sites/cpo/Reports/2012/NOAA_SLR_r3.pdf, http://www.realclimate.org/index.php/archives/2019/03/alpine-glaciers-another-decade-of-loss/, https://tidesandcurrents.noaa.gov/publications/techrpt83_Global_and_Regional_SLR_Scenarios_for_the_US_final.pdf, https://tidesandcurrents.noaa.gov/publications/NOAA_Technical_Report_NOS_COOPS_073.pdf, Explaining the NOAA Sea Level Rise Viewer, Rising Sea Levels Threaten Hawaiian Sea Turtles’ Nesting Sites, Climate Change: Arctic sea ice summer minimum.

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. Church, J.A., P.U. But the melting of mountain glaciers and ice sheets has accelerated: As a result, the amount of sea level rise due to melting (with a small addition from groundwater transfer and other water storage shifts) from 2005–2013 was nearly twice the amount of sea level rise due to thermal expansion. From 2018 to 2019, global sea level rose 0.24 inches (6.1 millimeters). Interactive Map Climate change Snapshots of a warming world. 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 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. If melted completely, the Greenland ice sheet contains enough water to raise sea level by 5-7 meters (16-23 feet). NOAA Tech. The climate projection methodology is described in full in Rasmussen et al. Zoom into a familiar location, create a point, and share your story. Mailing Address:

To estimate how much of the increase in sea level is due to actual mass transfer—the movement of water from land to ocean—scientists rely on a combination of direct measurements of melt rate and glacier elevation made during field surveys, and satellite-based measurements of tiny shifts in Earth’s gravity field. Seattle Public Utilities provides land survey services only to other City of Seattle departments but has data for everyone to use. 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. Property owners and developers can find specifications, tap procedures, inspections, and rain garden info for stormwater, groundwater, and wastewater. Our large watersheds supply safe and clean drinking water to the greater Seattle area. Seattle has over 1,200 miles of sewer pipe. How much it will rise depends mostly on the rate of future carbon dioxide emissions and future global warming. Address:
