  • Rising Sea Levels were Faster in the Previous Century than in the Past Three Millennia

The rising sea levels have been faster in the previous century than in the past three millennia.

The sea levels on a worldwide level rose faster in the 20th century than in the past 3000 years. A Rutgers University study corroborated this fact. Had the variable of global warming not taken place, the rising sea levels would not have occurred so fast.

They may even have dropped a little. From the years 1900 to 2000, global sea levels rose up to 14 centimeters. That is quite a big jump especially for the lowlands of the coastal areas which were automatically inundated. 

While the 20th century rise was peculiar to say the least, the rise in the last two decades has been even more dramatic. The study was published in the journal Proceedings of the National Academy of Sciences.

"The 20th century rise was extraordinary in the context of the last three millennia - and the rise over the last two decades has been even faster," said Robert Kopp, the lead author and an associate professor in Rutgers' Department of Earth and Planetary Sciences.

A novel statistical method was employed in the study. It took two and a half years to reach completion as a tool-of-the-trade. Local recordings do not measure global sea levels.

Sea levels are a locality-based measurement. That is the way it has always been. The local measurements cause the readings to turn out different from the global standards. 

The obstacle was in the reading of a global premise. This was readily accomplished thanks in no small part to the new statistical method. One thing to be noted down is that from the years 1000 to 1400, global sea levels declined by 8 cm.

This was when the temperatures had gone down by 0.2 degrees Celsius. This is a strange occurrence. On the contrary, today the average global temperature has increased by one degree Celsius. Thus the rise in sea level does not come as much of a surprise. 

Since statistics can normally be bent or molded to fit whatever form mankind wants, the data behind the statistical procedures was also examined. Therefore a team of scientists recorded data from various marshes, coral atolls and prehistoric sites.

These were extant during the past 3000 years. The response of sea levels to temperature rise is the crux of the matter. The recordings of sea level rise during the past three millennia provide a context in which to see the overall trend.

As the database has amassed sufficient evidence regarding sea level changes and global temperatures through the ages, the delicate relation between the two variables has been calculated with razor sharp accuracy. The future trends do not look to be too bright. Sea levels will rise by another 1.7 to 4.3 feet by the end of the current century.
