Graph Of Rising Sea Levels

Currently it is rising at a rate of over three millimeters per year. So not only is sea level rising but also it is rising at a faster rate than in the past.

The site displays a current graph of estimated mean sea level.

Graph of rising sea levels. Multiply the area of the world ocean by the average annual rate of sea level rise to estimate the increase in volume of water that occurs each year or decade. In 2014 global sea level was 26 inches above the 1993 averagethe highest annual average in the satellite record 1993 present. Sea level continues to rise at a rate of about one eighth of an inch per year.

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. Since 1993 however average sea level has risen at a rate of 011 to 014 inches per yearroughly twice as fast as the long term trend. After a period of approximately 2000 years of little change not shown here global average sea level rose throughout the 20 th century and the rate of change has accelerated in recent years.

Between 1993 and 2003 the contribution to sea level rise increased for both sources to 279 millimeters 011 inches per year ipcc ar4 wg1 2007. Based on their new scenarios global sea level is very likely to rise at least 12 inches 03 meters above 2000 levels by 2100 even on a low emissions pathway. A project by the 2 degrees institute.

Global sea level has been rising over the past century and the rate has increased in recent decades. This is the uncertainty margin or the range from the mean average within which there is a high probability that the true number resides. Rsl is a combination of the sea level rise and the local vertical land motion.

1 when averaged over all of the worlds oceans absolute sea level has risen at an average rate of 006 inches per year from 1880 to 2013 see figure 1. How do i use the site. Sea level rise is speeding up.

Sea level was rising slowly 03 03 mm yr1 from ad 1500 to ad 1900 but during the 20th century the rate increased to 28 05 mm yr1 in agreement with instrumental measurements commencing in 1924. The global sea level trend has been recorded by satellite altimeters since 1992 and the latest global trend can be obtained from noaas laboratory for satellite altimetry with maps of the regional variation in the trend. Scientists forecast that in just the next 20 years the sea will have risen by another 6 inches.

For example when we say that global mean sea level for a particular month is 50mm 4 mm the true value for that month has a high probability of being between 46 and 54 mm. See how global sea levels have changed over the past 800000 years with this fully interactive global sea levels graph featuring the most recent historical sea level data and global temperatures. On future pathways with the highest greenhouse gas emissions sea level rise could be as high as 82 feet 25 meters above 2000 levels by 2100.

If the rate of sea level rise remains constant how much will it rise in a century.
