sea level rise it accelerated in the last ten years compared to previous decades, according to a study published by the Nature magazine.
The study contradicts the estimates and forecasts of further research, which showed that the growth of water level was lower in the last decade compared to previous years.
When calculating growth over sea level, the scientists found that between 1993 and 1999, the growth was lower of the published in previous studies and had to adjust between 0, 9 and 1.5 millimeters 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 to the data.
The research highlights that previous studies based on satellite data did not take into account movement vertical terrain (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 positioning system Global (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 get a variation the level of the oceans closer to reality.
The study authors note that is “reasonable” to think that this acceleration in sea level rise is because Antarctic ice and the area of Greenland melts, as recent studies have also shown.
