Mourners are gathering in Iceland to commemorate the loss of Okjokull, which has died at the age of about 700.
The glacier was officially declared dead in 2014 when it was no longer thick enough to move.
What once was glacier has been reduced to a small patch of ice atop a volcano.
Prime Minister Katrin Jakobsdottir, Environment Minister Gudmundur Ingi Gudbrandsson and former Irish President Mary Robinson are due to attend the ceremony.
After opening remarks by Ms Jakobsdottir, mourners will walk up the volcano northeast of the capital Reykjavik to lay a plaque which carries a letter to the future.
RTWT — the obituary on the plaque says it all.
Trump is not expected to attend the ceremony.
