The UN’s annual climate change summit opens on Sunday with hosts Egypt billing it as the world’s “watershed moment” on climate action.
More than 120 world are leaders heading to the Red Sea resort of Sharm el-Sheikh.
About 30,000 people will attend the two-week summit, known as COP27, though some activists are staying away over concerns about Egypt’s rights record.
The past year has seen extreme weather regularly linked to climate change.
The summit will open with welcome speeches from the UN’s new climate change chief, Simon Stiell, and Egyptian Foreign Affairs Minister and COP27 President-Designate Sameh Shoukry.
