Global Sea Level Increasing at Accelerated Rate

Over the last two decades, a significant rise has been witnessed in the sea levels. Researchers of a new study have assessed sea level data from 1993 to 2014.

The researchers came to know that an earlier model, which depicted sea level rise is taking place at a reduce rate in the last decade has actually miscalculated the rate for the decade before it. When the data was adjusted, the rate was seen as increasing.

Since 1993, overall rate of sea level rise has been increasing when compared with the years before then. Melting ice in the Arctic and West Antarctica is the main reason behind sea level rise. The place, which is facing the maximum risk from rising sea levels are coastal zones.

It is suspected that inundation events will become more common. “The thing that was really puzzling us was that the last decade of sea level rise was marginally slower, ever so subtly slower, than the decade before it”, said study’s lead researcher Dr. Christopher Watson from the University of Tasmania.

Watson said it was the error that gave the illusion that sea level rise is decreasing by 0.058mm/year 2 between 1993 and 2014. In reality, it increased between 0.041 and 0.058 mm/year 2.

The new information is in line with what UN’s climate science body, the Intergovernmental Panel on Climate Change (IPCC) has stated. The IPCC’s report found the sea rising on an average by 3.2 mm per year since 1993. Watson’s study found the rate between 2.6 and 2.9 mm per year.

Watson said the rise is taking faster over the last two decades in comparison to what it has been over the 20th century and now is getting faster again.
