Alaska: Alsec glacier melted the size of the lake double and the hill named ‘Pro Knob’ has now become a new island. NASA Satellite recorded this change, which is a major sign of climate change.
NASA Satellite imprisoned photos.Alaska Of Southeast Part From One A unique picture has surfaced. Due to the melting of a glacier here, a new island has emerged in the middle of the lake. NASA’s satellites saw with their eyes and recorded it in the pictures.
This new island is actually a small hill named ‘Pro Knob’. First these four Side Alsech glacier was surrounded by snow. The size of the lake increased due to ice melting and retreat. Gradually the water surrounded the entire space and the Prof. Knob was cut off from the rest of the ground.
Difference between NASA’s old and new pictures
NASA’s Landsat-5 satellite took pictures of Pro Knob in July 1984. Then one edge of the hill touched the lake, but most of the part was in the grip of thick ice. In the next four decades, pictures show how Lysak The glacier retreated continuously. Along with this, the Grand Plato Glacier spreading towards the south also melted. Due to the back of both the glaciers, the scope of the lake increased and Pro Knob has now become the lone island.
20How was the picture in the century?
Glacier scientists say that Alsech Glacier somewhere in the beginning of the 20th century More Was huge. Then it was spread to the ‘Gateway Knob’ located about 3 miles west of the Prof. Knob. But since 1984, it has slipped a distance of more than three miles back.
The back of the glacier had a direct impact on the Alsech lake. In 1984, this lake spread to about 17 square miles. But today its scope is almost Double It has reached 30 square miles. Scientists call such lakes as ‘Progalasial Lake’, that is, the lake which is formed and increased by the melting of the glacier.
