Larsen B Ice Shelf Collapse


Global Warming. The Collapse of the Larsen B Ice Shelf. Posted by Picasa

LATER THAT YEAR, October 4, 2002; the ice river C Zero reversed it's direction as a result of melt water running under the ice. On the same day the mechanism of Global Warming manifested and has yet to abate in the way of vortices. There were two that morning, one in the Northern Pacific and one in the Northern Atlantic. I found it odd that on the same day I read about C Zero the vortices came under my gaze as well. It was a stark reality that validated by concern after this collapse.

The Larsen B ice shelf collapsed and broke away from the Antarctic Peninsula during February and March, 2002 — a progression observed by Terra's Moderate-resolution Imaging SpectroRadiometer (MODIS) and analyzed at the University of Colorado's National Snow and Ice Data Center. The collapse is thought to have been accelerated by warm summer temperatures which caused meltwater to fill crevasses along the landward side of the Larsen shelf, leading to intensified pressures within the sheet structure.
