How Globle Warming Effect in Three Decades NASA Realeased Shocking Image

Shocking images released by NASA show how soaring temperatures in the Arctic have caused an enormous glacier in Iceland to melt - in just three decades.

The Okjökull glacier, which once measured six square miles (16 km²) and is known as Ok, has now completely vanished.

Images taken in 1986 show the glacier covering a huge mountainside in the west of Iceland but, in the latest photo, a tiny patch of ice is all that remains

Okjökull has thinned so much that it no longer has enough mass to flow. Pictured: A closeup of the Okjökull glacier and the crater of the volcanic mountain it sits on, taken on September 7, 1986

Okjökull, part of the Langjökull group of glaciers, was officially declared 'dead' in 2014. Pictured: A closeup of the former glacier site, as seen in 2019

HOW IS GLOBAL WARMING AFFECTING GLACIAL RETREAT?

Global warming is causing the temperatures all around the world to increase. 

This is particularly prominent at latitudes nearer the poles. 

Rising temperatures, permafrost, glaciers and ice sheets are all struggling to stay in tact in the face of the warmer climate.

As temperatures have risen to more than a degree above pre-industrial levels, ice continues melt.

For example, melting ice on the Greenland ice sheet is producing 'meltwater lakes', which then contribute further to the melting. 

This positive feedback loop is also found on glaciers atop mountains. 

Many of these have been frozen since the last ice age and researchers are seeing considerable retreat. 

Some animal and plant species rely heavily on the cold conditions that the glaciers provide and are migrating to higher altitudes to find suitable habitat. 

This is putting severe strain on the ecosystems as more animals and more species are living in an ever-shrinking region. 

On top of the environmental pressure, the lack of ice on mountains is vastly increasing the risks of landslides and volcanic eruptions.

The phenomena is found in several mountain ranges around the world.

It has also been seen in regions of Antarctica.
