According to recent calculations by glaciers, geologists and geophysicists, most of this reduction in the size of glaciers began after 2000.
In the last 20 years due to global warming, Iceland’s glaciers have lost about 750 square kilometers, or seven percent of their surface space. This information has been found in a study published on Monday.
A study by the Icelandic scientific journal Jokul states that the glaciers present in Iceland are spread over 10 percent of the country’s land. In 2019, it was over 10,400 square kilometers. Since 1890, the land covered by glaciers has decreased by about 2,200 square kilometers, or 18 percent.
According to recent calculations by glacier experts, geologists and geophysicists, most of this decrease in the size of glaciers started after 2000. Experts previously warned that Iceland’s glaciers were at risk of disappearing completely by 2200.
The speed at which the ice has started in the past two decades is comparable to the total surface area of Hofsjökull, the third largest ice cap in Iceland, covering about 810 square kilometers.
The authors of this study point out that variations in glacier areas in Iceland since 1890 show a clear response to changes in climate. That said, they have been rather syncretic across the country. However, some glaciers have been affected due to subglacial volcanic activity.
In 2014, Glaciers knowledgeable people revoked the recognition granted to the Okjokull glacier as a glacier. This was the first time in Iceland. The reason behind this was that it was made of dead ice and was no longer moving like glaciers.
According to a study published in the journal Nature in April, around 2,20,000 glaciers of the world are disappearing at a rapid pace on a large scale. In this way, they are contributing in a big way in increasing the global sea level in this century.
Analyzing images taken by the US space agency NASA’s Terra satellite, they found that the world’s glaciers lost an average of 267 billion tonnes of ice each year between 2000-2019. The team also found that the rate of melting of glaciers increased rapidly during the same period.
The team found that between 2000 and 2004, glaciers lost 227 billion tons of ice every year. But between 2015-2019, glaciers lost an average of 298 billion tonnes of ice each year.
These results of this study will be included in the forthcoming assessment report of the United Nations Intergovernmental Panel on Climate Change due in 2022. Let us know that melting of glaciers has come as a new challenge for the world. Due to this the risk of drowning of coastal areas has started increasing.
