Earth’s Cryosphere is Dwindling by 87,000 Square Kilometers Annually

According to a new study, due to climate changes, the Earth’s Cryosphere is reducing by around 87,000 square kilometers annually on average between 1979 and 2016.

The study is the first of its kind to offer a global approximation of the Earth’s surface area roofed by frozen ground, snow cover, and sea ice.

The land covered with frozen water is of equal importance as its mass as the white surface reflects sunlight very efficiently, keeping the planet cool.

Changes in the location and size of snow and ice might change the sea level, change air temperatures, and can also affect ocean currents across the globe.

A physical geographer at Lanzhou University, Xiaoqing Peng, said that the Cryosphere is the most sensitive indicator for climate change and the earliest to reveal a changing world.

He further added that the change in its size represents a huge global change rather than a local or regional issue.

The Cryosphere and few mountainous regions hold approximately three-quarters of fresh water on Earth. Shrinking glaciers is a major threat to supplies of drinking water.

Several scientists have scripted the loss of Arctic sea ice, dwindling snow cover, and shrinking ice sheets separately because of climate changes.

But none of those studies clarified the dimensions of the Cryosphere over the globe and its role in temperature controls.

The dwindling mainly occurred in the Earth’s Northern Hemisphere, with a reduction of around 102,000 square kilometers or approximately equal to half the Kansas area annually.

The area of the Cryosphere in the Southern Hemisphere has increased by 14,000 square kilometers approximately.
