COP27, the 27th Session of the Conference of Parties to the United Nations Framework Convention on Climate Change (UNFCCC), started on November 6, 2022. The event, hosted by Egypt, marked the 105th anniversary of the Great October Revolution and took place 869 years after The Treaty at Wallingford.

This is not the first COP summit in Africa: COP7 and COP15 were held in Marrakesh, COP12 in Nairobi, and COP17 in Durban. UNFCCC is a very travel-happy organization, moving events from one continent to another almost every year.
