(.#A.009).- The immense southern ice field of the Pentagonia splits in two.
Warming breaks the ice.
Posted on June 18, 2019.
The 12,000 square kilometers of the Pentagon's ice field have split in two and are likely to continue to fracture due to climate change, Chilean scientists who study the region said last month. Temperatures are rising in the Andes Mountains, on the border of Chile and Argentina. As a result, there is less snow and ice to replenish the many glaciers in the region. The southern ice field is the largest frozen surface in the southern hemisphere, outside of Antarctica.
2.7 cm rise in sea level between 1991 and 2016 caused by the melting of glaciers around the world (9000 billion tonnes less ice), according to IRSTEA (French Institute for Research in Science and Technology for Environment and Agriculture.
A risk of enlargement.
1- The ice naturally reflects the sun's rays.
2- But the heat can lead to movements of the snow. Its friction can cause glacier breaks,
3- The bare rock is warming up under the sun's rays.
4- The ice can get warm because of the higher temperature of the nearby bare rock. And it melts, which increases the separation.
The separation leaves between the two pieces of ice a breach of bare rock 100 meters wide.
As big as half of Quebec City in Canada.
The ice mass that separated from the main glacier is estimated at 208 square kilometers, a little less than half of the nation's capital. This is a relatively small part of the ice field.
