On April 4, Wilkins plate located at the Antarctic Peninsula has broken away from the frozen continent. This huge block of ice as big as New York City.
Thickness
The split plate Wilkins has operated at its thinnest part, a bridge 500 meters wide.
Icebergs
Following the posting of this giant block of ice in Antarctica, many icebergs are formed and drift.
Tracks
Within two years, the area of Arctic sea ice has lost 22%. In 2007, this loss reached a record with a cast of 1.2 million square kilometers of ice.
Gel
The Arctic Ocean could be ice-free in 50 years to a century. The impact on ecosystems and climate are dramatic.
Panorama
Antarctica contains 90% ice and 70% of freshwater reserves.
Ark
The thickness of the ice in Antarctica varies from 2 000 to 5 000 meters from place to place. But it tends to decrease as a result of global warming.
Aube
The researchers recorded a significant drop in salinity around Antarctica. Fresh water from melting glaciers dillu the salt concentration.
Erosion
Contrary to what one might think, the melting of icebergs and ice does not raise the water level. It’s the same principle as the ice floating on water.
Underwater
The change in salinity of sea water directly affects ocean currents. This has consequences on the climate.
Crack
If the frozen continent, Antarctica, and Groëland were to melt, the worst is to fear for the planet. Entire countries were wiped off the map.
Block
The complete disappearance of Antarctica would raise sea levels by 70 meters, it would be 6 meters for the loss of Greenland.
Sculptures
During this century, scientists have recorded a temperature increase of 3 ° C at the Antarctic Peninsula.
Float
These huge pieces of ice floating on the ocean, the icebergs are monitored by satellite to thousands of kilometers high.
Ile
The disappearance of sea ice threatens an entire ecosystem. Many species such as polar bears are destroying their natural habitat.
Language
Glaciers worldwide are facing the same fate as the poles. Chinese scientists have recorded a decline de196 sq km of glacier plateau of Qinghai-Tibet in 40 years.
Lair
The ice prevents the glaciers flowing toward the ocean. If it disappears, no further barrier can keep them there and the water level will rise.
Tabular
The ice of the ice reflects light energy from the sun. If it melts, there will be a decrease in the reflectivity. The oceans store, then more energy which contributes to the warming and, therefore, the weather disturbance.
Fracture
Scientists predict an average increase in temperature from 3.8 to 7.2 ° C on Earth by 2100. The poles will be hit hard.
Glacier
Permafrost, ground that remains frozen all year, is threatened by global warming. Basing it releases carbon trapped over millions of years, which increases the concentration of greenhouse gas emissions.
