Vulnerability to sea-level rise of the coast of the Río Negro province

Mostrar todas las versiones(3)

According to the global predictions by the International Panel of Climate Change (IPCC), the sea-level rise due to ocean thermal expansion and glacier mass loss will average 0.09 - 0.88 m between 1990 and 2100, with a trend toward an increasing rise rate. Potential impacts of this increasing rise ra...
