Mourners gathered in Iceland this week to commemorate the loss of Okjokull, which has died at the age of about 700. Click here to read the full story.

What once was glacier has been reduced to a small patch of ice atop a volcano.

After opening remarks by Prime Minister Ms Jakobsdottir, mourners walked up the volcano northeast of the capital Reykjavik to lay a plaque which carries a letter to the future.

"Ok is the first Icelandic glacier to lose its status as glacier," it reads.

"In the next 200 years all our main glaciers are expected to follow the same path. This monument is to acknowledge that we know what is happening and what needs to be done.

"Only you know if we did it."

The dedication, written by Icelandic author Andri Snaer Magnason, ends with the date of the ceremony and the concentration of carbon dioxide in the air globally - 415 parts per million (ppm).
