In 2014, Ok became the first glacier in Iceland to lose its status as a glacier due to heavy melting, and is now referred to as dead ice. This could also become the fate of the other 400 glaciers in Iceland. On one side of the former glacier, there is now a sticker exclaiming “A letter to the future”. The icelandic author Andri Snær Magnason wrote “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 letter is signed “415ppm CO2” – the highest carbon dioxide level measured in the air.
