The figure will help to assess which scenario(s) the trajectory of sea level rise is following The graph is customizable and can be resized, printed, or pasted into your website. A list of the tide gauges used is available here (zipfile, 21,008 bytes) The paper describing this is: Church, J. E1434-E1441.
between the calculated trends if their 95% confidence intervals overlap. The interannual variation for many Pacific stations is closely related to the The plot shows the interannual variation of monthly mean sea level and the 5-month running average. Scientists forecast that in just the next 20 years, the sea will have risen by another 6 inches. See how Global sea levels have changed over the past 800,000 years with this fully interactive global sea levels graph featuring the most recent & historical sea level data and global temperatures. Choose from 4 color themes to match your website's look and feel. The average seasonal cycle and linear sea level trend have been removed. If several recent years have anomalously high or low water levels, the values may actually move slightly away from the true long-term linear trend. A project by the 2 Degrees Institute. A 30-year data set should provide a trend with a +/- 1.5 mm/yr confidence interval; The long-term linear trend is also shown, including its 95% confidence interval. Follow the IPCC. the linear relative sea level trends can be recalculated each year. The main effect of including a few more years of data is to narrow the 95% confidence intervals. A late Pleistocene sea level stack. Mitrovica, E.D. doi:10.1073/pnas.1517056113. The interannual variation for many Pacific stations is closely related to the The solid horizontal line represents the linear relative sea level trend using the entire period of record. Driven by climate change, global mean sea level rose 11–16 cm in the twentieth century 1,2.Even with sharp, immediate cuts to carbon emissions, it could rise … This is a free service, but we do ask for a Choose a theme and then copy & paste the code below where you would like it to appear on your website.Global sea levels are updated as soon as the latest values become available.

As more data are collected at water level stations, The rate of sea level rise or fall has been determined for long-term U.S. water level stations. View global sea levels and/or temperature over a span of thousands of years or zoom to specific time periods. and N.J. White. Facilitated by Dr. Carlos Primo David, chair of the NPTE, the forum aimed to share good practices, innovative technologies, and latest policy reforms on sea level rise. Proceedings of the National Academy of Sciences, Vol. with its six regionalized sea level rise scenarios plotted relative to a 1991-2009 baseline period In the last five years, sea level has risen 66% faster than the historical rate, and is now rising by an average of one inch every five years. Climate of the Past, Vol. 1079-1092. doi:10.5194/cp-12-1079-2016. The plot shows the monthly mean sea level without the regular seasonal fluctuations due to coastal ocean temperatures, salinities, winds, atmospheric pressures, and ocean currents. The variation of each 50-year trend, with 95% confidence interval, is plotted against the mid-year of each 50-year period. 113, pp. For local and regional comparisons, the calculated average seasonal values for all non CO-OPS and CO-OPS Stations are available as tables in meters. The average seasonal cycle of mean sea level, caused by regular fluctuations in coastal temperatures, salinities, winds, Historical data from multiple sources are combined to produce a continual record from 800,000 years ago up to the present day. Monthly sea level data were used to obtain linear trends, seasonal cycles, and interannual variations. 2011.
Therefore, the most recent calculated trend is not necessarily more accurate than the previous trends; it is merely a little more precise.
