Arctic in the Oven: Milne Ice Shelf has collapsed

Milne Ice Shelf collapsed in the waters of the Arctic Ocean, the last intact Canadian ice shelf, close to Ellesmere Island. The cause is obviously climate change and the effects of a summer in the oven, as the scientists explained.

Milne Ice Shelf is almost 4,000 years old, the Milne Ice Shelf was the last intact ice shelf in the country until the end of July, when an Arctic ice scholar noted from satellite photos that it had lost 43% of its ice. ice.

The platform area has shrunk by 80 square kilometers. According to the Canadian Ice Service and according to Luke Copland, a glaciologist at the University of Ottawa: "Above-normal air temperatures, offshore winds and the open sea in front of the ice shelf are all ingredients in the recipe that has led to this collapse.

These are huge chunks of ice, the size of entire cities. That was the largest ice shelf that has remained intact and it has effectively disintegrated. " The whole planet that is overheating due to climate change. But in the past 30 years, the Arctic has warmed at twice the rate of the global average, due to a process called Arctic amplification.

And this year the temperatures in the region are even more intense, so much so that the polar ice cap has reached its lowest in 40 years. The collapse of the ice shelf on Ellesmere Island also resulted in the loss of the last known epishelf lake in the Northern Hemisphere.

Epishelf lakes are a particular geographic formation that forms when melted fresh water is trapped under a floating ice shelf - this fresh water does not mix with the salt water below, but floats on ocean water.

It's August but it looks like Winter in the Italian Alps

In Italy, despite the sultry days of this first week of August, the snow at the Stelvio pass, in the Italian Alps has fallen copiously, in an unusual midsummer snowfall.

Over the last few hours, more than 20 centimeters of snow has fallen, which has whitened the streets and parked cars. Temperatures have dropped suddenly in the last few hours across Northern Italy. And to think that we are in the summer, like many people enjoying the sun and the sea.

While the snow was hiding in winter. Another relentless sign of climate change: the Italian Alps covered with a blanket of snow in August while the rest of the country gasps with the heat and the high pressure field that has dramatically raised temperatures.
