Everyone knows it, the planet is warming every day and the glaciers and ice continue to melt.
Famous French explorer Jean-Louis Etienne said: “I crossed Antarctica in 1990 conf with Claude Lorius who was already talking about melting ice with this formula:” the process is started, “” he says. For the first man to have reached the North Pole alone in 1986, the melting ice is far from being only a theory, since he himself was able to see it in action during his travels. “There is a retreat of the polar ice caps, especially in Greenland,” he insists, “I was there in March and it is undeniable that the ice has receded.”
Eternal snows are melting and disappearing!
“The ice that is at the North Pole is a layer of the frozen sea”, summarizes Jean-Louis Étienne, “it is formed of the multi-year ice, also called eternal snows and a layer of ice that is formed in the year. ” The problem is that climate change is altering this process of renewing the ice cap. “At the North Pole, the eternal snow disappears and there is only the ice of the year that is only one to two meters thick.”
The loss of a balance between the poles
Also a physician, Jean-Louis Étienne details the functioning of the planet in the manner of that of a human body. “Poles are essential to the climate machine,” he explains, “the heat of the tropics must be exchanged with the poles in order to preserve a balance.” The problem is therefore that the global increase in temperature, at the poles as in the tropics, induces an imbalance in this exchange. “We lost 4 ° C at the North Pole,” explains the explorer. “We opened the door of the fridge, we go to the cold to balance the heat of the tropics.”
Jean Louis Etienne is also preparing the Polar Pod Expedition to study the Antarctic Circumpolar stream.
“The Southern Ocean is not limited by the continents like all the oceans of the world; it is an ocean in motion that circulates from west to east around Antarctica, which is called the Antarctic Circumpolar Current.
It is a major player in the climate, which is still poorly known due to its remoteness, its isolation outside the traditional navigational zones, the high cost and therefore the rarity of oceanographic campaigns.
So there is a wait in the scientific community.
POLAR POD, as a satellite around Antarctica, will allow the acquisition of data and long-term observations that will be transmitted to researchers, oceanographers, climatologists … involved in the project.
The sharing in real time of the expedition by the image, the sound, and the voices, will feed a great international pedagogical project on the Sciences of the Life and the Earth.”
