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. By 2005, the glacier had retreated, and the lake had become a small grassland. 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. This is an increase of 0.24 inches (6.1 mm) from 2018. With climate change, the water cycle is expected to undergo significant change. In: Climate Change 2013: The Physical Science Basis. We have programs to help you save on your utility costs. From the 1970s up through the last decade or so, melting and heat expansion were contributing roughly equally to observed sea level rise. 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. IPCC. 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. Seattle Public Utilities is investing in our infrastructure to protect public health and the environment and to continue providing essential services to customers. Geophysical Research Letters, 45(24), 13,367-13,376. https://doi.org/10.1029/2018GL081183, IPCC, 2019: Summary for Policymakers. [online] http://cpo.noaa.gov/sites/cpo/Reports/2012/NOAA_SLR_r3.pdf. Alpine glaciers: Another decade of loss. 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. Explore information about some of Seattle Public Utilities' completed construction projects, including summaries and documentation. As the world warms, land ice and ice shelves melt, with their water flowing into the global oceans. Published by the National Oceanic and Atmospheric Administration. National Oceanic and Atmospheric Administration, National Ocean Service, Silver Spring, MD. Seattle has over 1,200 miles of sewer pipe. Construction Resources. (2011). Merrifield, G.A. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. Interactive Map Climate change Snapshots of a warming world. Sea level is measured by two main methods: tide gauges and satellite altimeters. How fast it will rise depends mostly on the rate of glacier and ice sheet melting. Sea level can rise by two different mechanisms with respect to climate change. 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. Global warming is causing global mean sea level to rise in two ways. 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. Naturally occurring ocean climate cycles can also play a role in temporarily masking or enhancing the effects of climate change on sea level rise. We provide construction professionals with guidelines, specifications, and permits to connect to Seattle's water and sewer systems. See how we maintain these services for you. ... Sea-Level Rise. Accessed November 2, 2015. Do you have feedback to offer on this or another article?Let us know what you think. As seas rise, saltwater is also contaminating freshwater aquifers, many of which sustain municipal and agricultural water supplies and natural ecosystems. 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. By the end of the century, global mean sea level is likely to rise at least one foot (0.3 meters) above 2000 levels, even if greenhouse gas emissions follow a relatively low pathway in coming decades. http://doi.org/10.1007/s10712-011-9119-1, Domingues, R., Goni, G., Baringer, M., & Volkov, D.

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. A LANDMARK UN report has warned sea levels will rise way faster than first thought by 2100, so how much of the UK will be under water by that time? 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. View central estimates. Climate change is expected to … The interactive map, produced by Climate Central, shows the change in the UK in the next 30 years because of rising sea levels. Antarctic ice loss nearly quadrupled from 51 billion tons per year between 1992 and 2001 to 199 billion tons per year from 2012-2016. Water Outages View our current water outage map and read about how you can prepare for planned water outages. All three utilities strive to operate in a cost-effective, innovative and environmentally responsible manner. We do our best to minimize the impact of our construction on your neighborhood. 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. Pfeffer, D. Stammer and A.S. Unnikrishnan. Water Outages View our current water outage map and read about how you can prepare for planned water outages. 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. Sea level rise and nuisance flood frequency changes around the U.S. NOAA Technical Report NOS CO-OPS 73, 53p. NOAA Tech.

In IPCC Special Report on the Ocean and Cryosphere in a Changing Climate [H.-O. Sea Level Change. By the end of the century, global mean sea level is likely to rise at least one foot (0.3 meters) above 2000 levels, even if greenhouse gas emissions follow a relatively low pathway in coming decades.

Cambridge University Press, Cambridge, United Kingdom and New York, NY, USA. Sea-Level Rise from the Late 19th to the Early 21st Century. Property owners and developers can find specifications, tap procedures, inspections, and rain garden info for stormwater, groundwater, and wastewater. For the densely populated Atlantic seaboard north of Virginia and the western Gulf of Mexico, sea level rise will likely be higher than the global average for all pathways. This Scary Map Shows How Climate Change Will Transform Your City Click on your city, and the map will pinpoint a modern analog city that matches what your climate may be in 2080. If melted completely, the Greenland ice sheet contains enough water to raise sea level by 5-7 meters (16-23 feet). Using data from scores of stations around the world, scientists can calculate a global average and adjust it for seasonal differences. The climate projection methodology is described in full in Rasmussen et al. Allen, J. Boschung, A. Nauels, Y. Xia, V. Bex and P.M. Midgley (eds.)]. (n.d.) Sea level trends. Residents and businesses can conserve, reduce waste, and practice sustainability. By 2050?
