From 28 May to 8 June 2023, Finland hosted the XLV Antarctic Treaty Consultative Meeting (ATCM) as well as the XXV meeting of the Committee for Environmental Protection (CEP). A total of 400 delegates attended the meeting in person.
SCAR attended the meeting as an Observer and plays important role in providing scientific advice to inform discussions. This year's SCAR lecture was given by Dr Heather Lynch on satellite-based science and the changing nature of Antarctic exploration. Prof Steven L Chown gave an Antarctic Climate Change and the Environment Decadal Synopsis update on the ATCM for a joint ATCM/CEP session on Climate Change.
Both lectures are available from our SCAR library:
- pdf SCAR Lecture 2023: "Satellite-based Science and the Changing Nature of What it Means to "Explore" Antarctica" (Lecture Slides) (9.92 MB)
- pdf SCAR Presentation: Antarctic Climate Change and the Environment Decadal Synopsis - Update to ATCM 45 (6.36 MB)
The ATCM adopted a declaration on climate change on the last day of the meeting. The Helsinki Declaration on Climate Change in the Antarctic was one of the key objectives of the meeting.
