Satellites Reveal Melting Antarctic Ice

Envisat satellite owned by the European Space Agency (ESA) observed that one of the three layers of ice on the Antarctic Peninsula have been melting. Global climate is getting warmer is claimed to be the driving factor.

Reported by Live Science, Envisat was initially mapped approximately 1235 miles or 3200 kilometers of the Larsen ice sheet. layer includes a layer of ice on the Antarctic Peninsula. Of mapping done Envisat, Larsen ice layer are grouped into three parts, namely A (smallest), B and C (the largest).


For more than a decade in orbit, Envisat has found ice in the layer B decreases. This layer has lost approximately 1790 square kilometers of territory in January 2005. Layer B is now less than 15 percent of its original size in 1995.

Meanwhile, since January 1995 A layer had disappeared, while the C layer remains in stable condition, although it began to melt from the observations show.

"the ice sheet is sensitive to temperature rises in the atmosphere and changes in ocean currents," said Helmott Rott, a professor from the University of Innsbruck in Austria.

He adds, "In the northern peninsula of Antarctica has been warming approximately 2.5 degrees Celsius, the atmosphere or the equivalent of 4.5 degrees Fahrenheit. Over the last 50 years the warming trend is stronger than the global average heat, causing melehnya the ice."

Envisat observations are scheduled to continue for at least two years. The new satellites called Sentinels are now being prepared and will be operational in 2013.
