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 […]
Cumulative SMB-D anomaly (2003–2008) and comparison with GRACE data (18). Short horizontal lines indicate GRACE uncertainty, dashed lines the linear trends. GRACE values are not absolute numbers, and the curve has been vertically shifted for clarity. The scatter plot in the inset shows a direct linear regression between the monthly GRACE values as a function […]
Mt. Kenya’s ice cap was so stunning that some began revering it as God’s home. But most of the shining glacier has now disappeared, robbing communities of water and leading to a crisis of faith. By Edmund Sanders, November 10, 2009 Reporting from Muranga, Kenya – From a tree-shaded plateau facing Mt. Kenya, the worshipers […]
Satellite observations and a state-of-the art regional atmospheric model have independently confirmed that the Greenland ice sheet is loosing mass at an accelerating rate, reports a new study in Science. This mass loss is equally distributed between increased iceberg production, driven by acceleration of Greenland’s fast-flowing outlet glaciers, and increased meltwater production at the ice […]
Outlines of the Kibo (Kilimanjaro) ice fields 1912, 1953, 1976, and 1989 (1), 2000 (2) and updated with Ohio State University aerial photographs taken October 15, 2007. (Inset) Areal extent (km2) versus time with a linear fit (R2 = 0.98). An ice cover map was produced by using the 2007 photos and combined with four […]
(a) Seasonal Melt Departure (SMD) for June-August and (b) seasonal maximum daily temperature anomalies at three coastal meteorological stations in Greenland for June-August from 1973 to 2007 (Mote 2007). The recent marked retreat, thinning, and acceleration of most of Greenland’s outlet glaciers south of 70° N has increased concerns over contributions from the Greenland Ice […]
By Jeremy Hance, www.mongabay.com, November 02, 2009 The most recent survey among the ice fields atop Mount Kilimanjaro found that the ice atop Africa’s most famous mountain could be gone in twenty years—and maybe even sooner. Published in the Proceedings of the National Academy of Science the study [pdf] was conducted by a team of […]
By Staff Writers, Buffalo NY (SPX) Oct 29, 2009 The possibility that climate change might simply be a natural variation like others that have occurred throughout geologic time is dimming, according to evidence in a Proceedings of the National Academy of Sciences paper. The research reveals that sediments retrieved by University at Buffalo geologists from […]
Jakobshavn Glacier in western Greenland has been rapidly losing ice from its terminus for more than a decade due to warm water currents reaching up the fjord. The arrow indicates direction of discharge, while the glacier retreats back towards the Greenland Ice Sheet. Another study focused on western Greenland’s Jakobshavn Isbrae responsible for draining 7 […]
By RANDOLPH E. SCHMID, AP Science Writer WASHINGTON — Global warming is messing with the planet’s thermostat. That warning came Thursday from Richard Spinrad, head of research at the National Oceanic and Atmospheric Administration, in releasing the annual update of science’s Arctic report card [pdf]. Warming temperatures continue in the polar north, changing wind patterns, […]
