Scientists want to re-freeze the Arctic
Recently, due to the melting of glaciers in the Arctic are quite increased sea levels. But the water level rise threatens not only the flooding of coastal land areas. Since concealing ice, roughly speaking, "dilutes" the sea water, warm currents get colder. All this can not but affect negatively on the climate of our planet. However, recently a group of scientists and architects offered to freeze the Arctic again. And a very elegant way.
Why is it important to restore the Arctic
In addition to the threat of climate change, which we have already mentioned, in the past few decades, the Arctic Ocean has lost about 30% of its ice cover. As a result of this endangered species were wild inhabitants of cold regions such as seals, polar bears, wolves, penguins and other animals.
How to freeze the Arctic?
Authors of the project offer to use special submarines that will sink to the depths of the ocean, collect sea water is filtered from salts and freeze it. At the exit turn out small pieces of ice in the shape of hexagons. The production of each of these pieces require 2027 cubic meters of water. All the hexagons can be connected to each other or to dock their side, or "thrown" under the glacier.
Our goal - the restoration of the polar ecosystem, which has a direct impact on the global climate, - says one of the authors of the project Faris Raja Kotahatuhaha.
Why can not it work?
It's simple: the approach to the formation of new ice treats, roughly speaking, a symptom, not a disease. The disease in this case - global warming. This is acknowledged and the authors of the work, but their ideas at the same time can help to slow down the destruction of the planet, until we figure out what to do with global warming.
Our project still will not stop global warming, but the recovery is melted glaciers will help to keep the Arctic fauna.
Also, at the moment it is not clear where the submarines will take energy to operate. After all, for the work of a "fleet" (and here, of course, a couple of submarines can not do), you just need some kind of a tremendous amount of energy, which could further aggravate the situation with the gas emissions into the atmosphere.
This is interesting: How would look like without the Greenland ice sheet?
The only option would be to use "clean" energy such as solar panels and hydrogen fuel, but this approach makes the project prohibitively expensive and in this case the resources where appropriate to put the fight against global warming itself, and not for the "freezing" of ice.
