This is another effect of global warming and the melting of the glaciers. Thirty-five lakes have made their appearance in the Savoie region during the past 40 years, according to Le Parisien, Sunday 26 July. This discovery is due to the naturalist Jean-Pierre Martinot and glaciologist Hugo Mansoux.
In The Dauphiné libéré, the first explains that with Hugo Mansoux " [they] simply crapahuté to the borders of Italy and, there, [have] overview due to the retreat of the glaciers these 35 lakes, the lakes because they are more than 0.5 ha. Some are still on their sea ice. Thus, it is simply linked to climate warming has been accelerating over the past 40 years. "These lakes are all at high altitude, mainly in the Haute-Maurienne.

other lakes should appear
The naturalist explains that these lakes can form in two ways. The water can either be housed in a cavity formed in the rock due to the erosion caused by the glacier when it moves. Otherwise, it is an effect dam : stones carried by the bottom of the glacier is accumulating, which will allow for the retention of natural water during the melting of the glacier.
According to Jean-Pierre Martinot, " these lakes that once formed over centuries will now appear in a few tens of years. It is symptomatic of the abrupt removal of the alpine glaciers. "This movement of creation of lakes would not be close to finished :" The figures from the Ipcc are greatly concerned that this thing is accelerating and will continue. Therefore, as long as there are glaciers and that they will shorten, it has good chances of finding new lakes ", he says, thinking that it may not remain for more than a few pieces of glacier in the future, in the Savoy region.
