The World Ocean became deeper - scientists


Global sea level is considered one of the most important indicators of climate changes on the planet. For the last 25 years global sea level has grown by 7,7 cm. The international team of scientists on the basis of satellite data has come to the corresponding conclusions, Earth System Science Data reports. Growth of level goes with an average speed of 3,1 mm a year and at the same time accelerates on 0,1 mm annually. Authors of a research have tried to estimate a contribution of various circumstances to an observed picture. By their calculations, thermal expansion of water plays the leading role so far - 42%. On a share of thawing of sea ices and also glaciers of Greenland and Antarctica, 21%, 15% and 8% respectively have. The water drain role to the ocean through the rivers isn't clear yet - scientists have noted that uncertainty is too big here to draw some conclusions. Global sea level is considered one of the most important indicators of climate changes on the planet. Others are the temperature of the ocean and absorption of heat by it, concentration of greenhouse gases, acidity of waters of the ocean, a condition of glaciers and a condition of sea ice. Earlier the group of scientists from Australia and the USA has analysed a condition of the World Ocean and has counted quantity unaffected the person of water areas.
