sea level rise accelerated in the last 10 years compared to previous decades, according to a study published today in the journal Nature .
The study contradicts the estimates and forecasts of further research, which showed that the growth of the water level was lower in the last decade compared to previous years.
When calculating again sea level rise, the scientists found that between 1993 and 1999 the growth was lower than in previous studies published and had to adjust between 0.9 and 1.5 mm less.
This means that, although the advance of the sea was slightly lower than what has been published in the past, growth has accelerated in recent years compared to the last decades of the twentieth century, as evidenced by the adjustments made in the data.
The research highlights that previous studies based on satellite data did not take into account the movement of the vertical field (VLM, for its acronym in English) to calculate the increase in sea level.
The team of researchers from the University of Tasmania in Australia, led by Christopher Watson used data from the Global Positioning System (GPS, for its acronym in English) combined with data from tide gauges distributed by the oceans.
This technique allowed the researchers could identify and correct errors in the measurements for a change in the level of the oceans closer to reality.
The study authors say it is “reasonable” to think that this acceleration in sea level rise is that the ice of Antarctica and the area of Greenland melts, as have also shown recent studies.
