New melting process is giving rise to sea level, new satellite research shows. Scientists have discovered a worrying process of melting ice sheets in Greenland and Antarctica that speeds up the rate of sea level rise.
A research published in Proceedings of the National Academies of Sciences on Monday shows new melting process is giving rise to sea level. Considering the current rate, the oceans around the globe will be at least on average 2 feet (61 centimeters) higher later of the century compared to today.
The melting ice sheets, caused by warming of the ocean making the world’s oceans surface layer less salty and more buoyant, according to a research which is based on 25 years of satellite data. It supports computer simulations of scientists and the United Nations’ predictions that reveal regular climate change reports.
Sea level rise has two factors including first year-to-year small rises and falls and another is larger long-term rising trends caused by natural events and man-made climate change respectively.
Sea level rise more than temperature marks a climate change according to director of Earth science, Anny Cazenave at the International Space Science Institute in France, who edited the study.
“Our results suggest that a further increase in the supply of glacial meltwater to the waters around the Antarctic shelf may trigger a transition from a cold regime to a warm regime, characterised by high rates of melting from the base of ice shelves and reduced formation of cold bottom waters that support ocean uptake of atmospheric heat and carbon dioxide,” said Alessandro Silvano, a PhD student at the University of Tasmania’s Institute for Marine and Antarctic Studies.
