"Sea levels are rising several times faster than they have in the past 2,800 years, with the process accelerating because of manmade global warming, according to new studies.An international team of scientists examined two dozen locations across the globe to chart rising and falling seas over centuries and millennia.Until the 1880s and the worlds industrialisation, the fastest seas rose was about 3cm to 4cm a century. During that time global sea levels did not get much higher or lower than 7.6cm above or below the 2,000-year average. But in the 20th century the worlds seas rose 14cm." - The GuardianFor More Info: http://www.theguardian.com/environment/2016/feb/23/sea-levels-rising-at-fastest-rate-in-2800-years-due-to-global-warming-studies-show
