Alert melting ice
FonteOn 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.
ThicknessThe split plate Wilkins has operated at its thinnest part, a bridge 500 meters wide.
IcebergsFollowing the posting of this giant block of ice in Antarctica, many icebergs are formed and drift.
TracksWithin 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.
GelThe Arctic Ocean could be ice-free in 50 years to a century. The impact on ecosystems and climate are dramatic.
PanoramaAntarctica contains 90% ice and 70% of freshwater reserves.
ArkThe 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.
AubeThe researchers recorded a significant drop in salinity around Antarctica. Fresh water from melting glaciers dillu the salt concentration.
ErosionContrary 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.
UnderwaterThe change in salinity of sea water directly affects ocean currents. This has consequences on the climate.
CrackIf the frozen continent, Antarctica, and Groëland were to melt, the worst is to fear for the planet. Entire countries were wiped off the map.
BlockThe complete disappearance of Antarctica would raise sea levels by 70 meters, it would be 6 meters for the loss of Greenland.
SculpturesDuring this century, scientists have recorded a temperature increase of 3 ° C at the Antarctic Peninsula.
FloatThese huge pieces of ice floating on the ocean, the icebergs are monitored by satellite to thousands of kilometers high.
IleThe disappearance of sea ice threatens an entire ecosystem. Many species such as polar bears are destroying their natural habitat.
LanguageGlaciers 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.
LairThe ice prevents the glaciers flowing toward the ocean. If it disappears, no further barrier can keep them there and the water level will rise.
TabularThe 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.
FractureScientists predict an average increase in temperature from 3.8 to 7.2 ° C on Earth by 2100. The poles will be hit hard.
GlacierPermafrost, 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.
