The disappearance glaciers?

The Alps are the most important mountain range in Europe, the only one to still have vast glaciers and from which the most important rivers of our continent. No exception of course our Valtellina, which may include among its natural beauty, some of the most beautiful and magnificent alpine glaciers. In our valleys
s the street is the second largest glacier in the Italian Alps, by extension, that of the furnaces, which with its 1,200 acres of surface glaciation is the flagship of the Valtellina. The
Valmalenco is not the least, presented a large number and wide people, among which the great plateau of Scerscen top and bottom and the two Fellaria, which although very small compared to the past, help to donate to this beautiful valley the great looks we all know.
Unfortunately, these giants are in grave danger, because in recent years, their withdrawal has taken an alarming rate, so as to cause concern in a few decades will be no more of these true spectacles of nature. The cause of this seems to be once again the man who, with his aggressive and unchecked activities, is causing climatic changes in recent decades have had an alarming acceleration. Apart from the trivial concerns related to skiing summer (I do not want to tour operators and those who live there with this activity), the disappearance of glaciers in the mountains would have an impact heavily on 'water supply, both as regards the' drinking water for productive use that, since This is one of the most important reserves of fresh water available, just think that in Lombardy glaciers contain a water resource by more than 4 km 3, equivalent to about forty large reservoirs. The increasingly frequent
succession of winters with low rainfall and hot summers with almost tropical characteristics in recent seasons has definitely put our knees in ice.
The summer of 2003, for example, was marked by positive thermal anomalies that they would be as important as the hottest of the century, causing a mass reduction of impressive equipment in the Alps and in particular the Lombardy area (see charts), synthesized in many millions cubic meters of ice.
The year 2006 has not been outdone: specific budget Glacier Southern Alps to Mount Sobretta for the last season (2005/2006) reported a net loss of water equivalent to 2300 mm , ie, an amount that corresponds to about 5 seasons of accumulation, only in late July that there was accumulation average in two seasons. In the same season for the Forni glacier are lost 130 cm thick ice to 3300 m and above the glacier Red Pass, and near the front, about 2600 m altitude, andatosene thickness is over 500 cm, with ablation that did not stop even during the autumn months (those that should ensure the highest cumulative contributions), leading to an overall loss apparatus over the past one hundred years of 40% of its length: 3.5 km against the current 6 beginning of the 20th century. And the winter season now winding down and went so far, for temperatures and accumulations, in the worst way. Data
disconcerting, of course, but touch all that you do not need to be an expert, just a leisurely stroll to the hut Marinelli - Bombardier, one of the favorite symbol of Valmalenco, the sight of the Bernina group. Once, to get there, we had set foot on the glacier of Casper, today ... well, no more, took refuge there, at the top, protected by steep walls of the homonymous peak and neighboring peaks of Musella, in agony, and its appearance would indicate that he is just waiting to disappear altogether. Look at these photos that show the glacier glacis from panoramic place before the refuge in 1975, when I was born, and today, little more than 30 years later. A comparison of ruthless which can only embitter those who experienced the splendor of ancient glacial traces Malence.
