claim: ( 2005 ), where satellite altimetry  established that the mean thickness of the entire Greenland ice sheet  had increased at 2 inches per year – a total of almost 2 feet – in the  11 years 1993-2003.”
evidence: This network was used, in combination with satellite altimeter data, to establish that global mean sea-level rose 19.5 cm ( 7.7 in ) between 1870 and 2004 at an average rate of about 1.44 mm / yr ( 1.7 mm / yr during the 20th century ).
