World leaders have arrived in Europe for the climate change conference COP26.
The conference is being held in the Scottish city of Glasgow and will run for two weeks, finishing on 12 November. However, Italy is also co-hosting, which means Italian leaders will help push important issues and lead debates.
The event is a global United Nations event. This is where more than 100 world leaders will meet to discuss how to tackle important issues surrounding climate change.
COP stands for Conference of the Parties, and will be attended by countries that signed the United Nations Framework Convention on Climate Change (UNFCCC) – a treaty agreed in 1994.
The 2021 meeting will be the 26th meeting, which is why it’s called COP26.
The COP26 will be the last climate change summit for German president Angela Merkel who is stepping down as German leader after 16 years in office.
US President Joe Biden and his climate special envoy John Kerry will also be in attendance.
Two of the biggest names in climate change activism, Sir David Attenborough and Greta Thunberg, will both be at COP26.
New Zealand Prime Minister Jacinda Ardern is not going to the conference. Instead, Climate Minster James Shaw has gone to represent New Zealand.
