Researchers will gather on Sunday in Borgarfjörður, Iceland, to commemorate Okjökull, or Ok, after losing its glacier status in 2014. The inscription entitled "A Letter to the Future" on the monument paints a gloomy picture.
"Ok, the first Icelandic glacier to lose its status as a glacier, and over the next 200 years, all our glaciers are expected to follow the same path, confirming that we know what is happening and know what is being done Only you know if we did it, "it says in English and Icelandic.
From the ice sheet in Greenland to the towering glaciers in the West Antarctic, the enormous ice masses of the earth melt quickly. And although sea levels have risen and fallen throughout history, scientists say it never happened so quickly.
If glaciers continue to melt at their present speed, this will pose a number of threats to the planet, geologists say. Here are some of the possible dangers:
It can displace people.
By 2100, according to a 2017 study, up to 2 billion people – or about one fifth of the world's population – could be forced out of their homes and forced to move inland because of rising sea levels.
Bangladesh is particularly vulnerable. About 15 million people in the country could become climate refugees when sea levels rise one meter. And more than 10% of the country would be under water.
Some displaced persons could not have a place to go to. They are not protected under international law, so that the industrialized countries are not required by law to grant them asylum.
It can submerge some islands.
When sea levels continue to rise rapidly Some isolated island states, including Tuvalu, the Maldives and the Marshall Islands, could possibly disappear.
You can reduce the drinking water.
Millions of people rely on glaciers for drinking water, especially in the Hindu Kush Himalayas and the Andes.
In dry climates near mountains, glaciers collect precipitation and fresh water and store it as ice during the colder months. When summer comes, the ice melts, flows into rivers and streams and supplies drinking water.
A glacial world would threaten water supply and potentially devastate effects, said Jason Briner, a geologist at the University of Buffalo CNN.
It can endanger our food supply.
