Introduction
The thaw is the period when the ice melts, because of the hot weather.
Thaw occurs in some parts of the world.
According to some experts opinion, the most affected area is near the Arctic.
In last years, the surrounded ice became 40% weaker and the area reduced itself 14%. All because the temperature’s average in Alaska Northern Canada and Siberia increased much more than the global average.
In about thirty years it increased 2.75°C.
Causes:
Thaw is a consequence of the undercurrents of the Antarctic.
Experts believe that there are geometrical sources in Arctic depths, where there were active volcanoes, 2000 years ago.
Atmosphere’s results
Ice reflects suns light and, because we are almost without ice, the sea is turning itself darker. Because of that it’s going to absorb sun radiations, which is going to increase the temperature’s levels – climate changes.
Seasons of the years are going to disappear.
Geosphere’s results
Land might become underwater, and that will cause alarming results to some islands, like the Azores.
The lost of all the ice matter.
Fusion between the ice and the sub soil has been provoked unsteadiness in airports and roads.
Biosphere’s results
It’s affecting millions of people.
It may provoke the extinction of several animal species, like polar bears.
Hydrosphere’s results
The increase of the level’s average of sea.
Stops undercurrents.
Curiosities
The most worrying is the glacier, named “Pine Island”, that moves 3.5 km each year.
