The continent of Antarctica has been losing more than 100 cubic kilometers (24 cubic miles) of ice per year since 2002. Measurements from the Grace satellites confirm that Antarctica is losing mass 11. Isabella Velicogna of JPL and the University of California, Irvine, uses Grace data to weigh the Antarctic ice sheet from space. Her […]
Irvine, Calif., December 14, 2009 — New space observations reveal that since October 2003, the aquifers for California’s primary agricultural region – the Central Valley – and its major mountain water source – the Sierra Nevada – have lost nearly enough water combined to fill Lake Mead, America’s largest reservoir. The findings, based on satellite […]
East Antarctic sheet shedding 57bn tonnes of ice a year and contributing to sea level rises, according to NASA aerial survey By Ian Sample, science correspondentwww.guardian.co.uk, Sunday 22 November 2009 18.00 GMT The world’s largest ice sheet has started to melt along its coastal fringes, raising fears that global sea levels will rise faster than […]
Distribution of 2003–2008 mass changes across the ice sheet. The period (2003–2008) was chosen to coincide with the GRACE and IceSAT epochs. Numbers indicate basin-integrated mass loss rates due to SMB and D (in Gt year–1). Numbers in the lower right corner represent the values for the whole ice sheet, indicating the dominant surface contribution […]
ScienceDaily (Nov. 29, 2008) — Researchers at the Laboratoire d’Etudes en Géophysique et Océanographie Spatiales and at a subsidiary of CNES have discovered that the accelerated melting of continental icepacks is the major reason for the rise in sea level over the 2003 to 2008 period, something which has minimized the effect of thermal expansion […]
