Which is the world’s second largest glacier?

Closeted in a lap of an archetypal U-shaped glacier valley with the Saltoro Hills to the west and Karakoram Range to the east in the Ladakh District of the state of Jammu and Kashmir, the Siachen Glacier is the longest (76 km) glacier in Himalaya and the second longest glacier in the world outside the Polar Regions.

Where is the biggest glacier?

The largest glacier in the world is the Lambert-Fisher Glacier in Antarctica. At 400 kilometers (250 miles) long, and up to 100 kilometers (60 miles) wide, this ice stream alone drains about 8 percent of the Antarctic Ice Sheet. Antarctic ice is up to 4.7 kilometers (3 miles) thick in some areas.

How old is the oldest ice on Earth?

To get that kind of neatly layered ice sample, scientists need to drill straight down through the thick Antarctic ice sheet. So far, the oldest ice collected that way goes back 800,000 years. Now, several groups from around the world want to drill down to ice that’s even older, more than 1.5 million years old.

Why are glaciers so blue?

Glacier ice is blue because the red (long wavelengths) part of white light is absorbed by ice and the blue (short wavelengths) light is transmitted and scattered. The longer the path light travels in ice, the more blue it appears.

Which is the second largest glacier in India?

How long until the glaciers melt?

Antarctica’s ice sheet could retreat 20 years sooner than expected. Factoring that in, the melting ice could raise the sea level by an additional 2.7 to 4.3 inches on top of the 10.6 to 14.9 inches that simpler models predict by the year 2100.
