A lengthening crack is threatening to cause an Antarctic ice shelf to collapse

A lengthening crack is threatening to cause an Antarctic ice shelf to collapse About 10 to 12 percent of the Larsen C Ice Shelf is expected to break off during such an event, leaving the larger ice shelf even more vulnerable to melting from increasing air and ocean temperatures.The iceberg and ice shelf melting would not, however, increase sea levels, since the ice is already resting in the ocean, like an ice cube in a glass.

The Terra Nova expedition: An ambitious and ill-fated attempt to reach the South Pole

The Terra Nova expedition: An ambitious and ill-fated attempt to reach the South Pole In 1910, British explorer Robert Falcon Scott embarked on an ambitious expedition to Antarctica, aiming to explore uncharted wastelands, conduct scientific studies and above all else, become the first person to reach the South Pole.Ernest Shackleton had come within 100 miles of the pole the previous year, and Norwegian explorer Roald Amundsen also had his sights set on reaching it first.

Startling aerial video reveals massive crack in Antarctic Ice Shelf

Startling aerial video reveals massive crack in Antarctic Ice Shelf The crack is expected to give rise to one of the largest icebergs on record, sometime within the next few months, though the precise timing of the breakup is unclear.Researchers from Project MIDAS, led by Swansea University, have reported several rapid elongations of the crack in recent years.

Here's what the Ice Age tells us about future sea level rise

Here's what the Ice Age tells us about future sea level rise Glaciers in Greenland, Antarctica and other areas have been melting rapidly in recent years due in part to increasing ocean temperatures.They also used Bassis' mathematical model for describing how ice reacts to air and ocean temperatures, and the implications for sea level rise.
