In 10 years, between 1993 and 2003, the overall average level of the sea, as measured by satellites Franco-American Topex / Poseidon and its successor Jason-1, was mounted at a relatively constant rate of 3 mm / year. The IPCC report, published in 2007, showed an increase of about 1.5 mm / year, was due to the expansion of ocean waters are warming, while 1.2 mm / year from loss of mass polar caps and mountain glaciers. Since 2003, there is still a fairly rapid rise of sea level (2.5 mm / year), but the warming of the ocean has less effect, the steric contribution (in the three-dimensional space) to higher level sea is only 0.4 mm / year.* The magnificent Perito Moreno glacier in Patagonia (Argentina). |
