Negotiators early Sunday approved a historic deal that would create a fund for compensating poor nations that are victims of extreme weather worsened by rich countries’ carbon pollution, but an overall larger agreement still was up in the air because of a fight over emission reduction efforts.

After that vote, talks on other aspects of the negotiations were put on hold while delegates were given 30 minutes to read texts of other measures they were to vote on.

The decision establishes a fund for what negotiators call loss and damage. It is a big win for poorer nations which have long called for cash — sometimes viewed as reparations — because they are often the victims of climate worsened floods, droughts, heat waves, famines and storms despite having contributed little to the pollution that heats up the globe

“This is how a 30-year-old journey of ours has finally, we hope, found fruition today,” said Pakistan Climate Minister Sherry Rehman, who often took the lead for the world’s poorest nations. One-third of her nation was submerged this summer by a devastating flood and she and other officials used the motto: “What went on in Pakistan will not stay in Pakistan.”
