Venezuelan singer-songwriter Jorge Drexler, who grew up around these glaciers, wrote a poignant lament[1] in anticipation of this day. The gist is that at this point the only thing to do is to grieve for the world we have already lost. I don't think there's anything else to say.
Y cuando el momento llegue, honremos nuestras heridas / Celebremos la belleza que se aleja hacia otras vidas / Y aunque la pena nos hiera, que no nos desampare / Y que encontremos la manera de despedir a los glaciares
(When the moment comes, let us honor our wounds / celebrate the beauty that goes off to other lives / and although the sorrow stings, I hope it will remain / and that we find a way to say goodbye to the glaciers)
