Glacier loss rates 2003-2009. Global map annotated to show the amount of glacial loss by mass for different regions of the Earth. The area of the red circles corresponds to the annual glacial mass loss from 2003 to 2009. The glacier mass change estimates are from a combination of satellite altimetry (ICESat), satellite gravimetry (GRACE) and in situ field observations. The circles also show total glacier area (green) and tidewater basin fractions (blue) for each region. The glaciers themselves are shown in yellow, exaggerated in size to aid visibility.
