Why in news
The potential collapse of permafrost in the Himalayas due to climate change is gaining attention.
Glaciologist S.N. Remya, part of this year’s Indian Arctic Expedition, is studying permafrost to assess disaster risks and provide early warnings to local communities.
What is permafrost
Permafrost is essentially any ground that stays frozen — 0 degree Celsius or lower — for at least two years straight.
These permanently frozen grounds are often found in Arctic regions such as Greenland, Alaska (the United States), Canada, Russia and Eastern Europe.
Although the ground remains perennially frozen, permafrost regions aren’t always covered with snow.
They can be found on land and below the ocean floor.
