Agreed Measures ?

Liability Annex

• Influencing factors– Antarctic values (peak science?); climate & environmental

change; increasing human activity; belief in the system

• Choice 1 – Business as usual– Huge past success leading to “interested laissez-faire”

• Choice 2 – Enhanced commitment– Determination to invest in current system– An ATS fulfilling its global responsibilities

• Choice 3 – Future reinvented– A revised 21st century governance regime

The Antarctic Treaty in 2056 – it’s a choice thing!

Rear Admiral John Martin, ONZM…

Exploring the Antarctic Treaty in 2056

• What will be the emergent threats?

• Is our organisation consistent with our strategy?

• What is the honourable thing to do?

• Why our history with Antarctica really matters as kiwis

• Why a policy pull on science is so important to New Zealand

• Why people in nature will ultimately keep the ATS strong

Antarctic Treaty System and Science

Guarantees continued freedom to conduct scientific research

Promotes international scientific cooperation including the exchange of research plans and personnel, and requires that results of research be made freely available

• Science and diplomacy increasingly important to NZs broader foreign policy agenda

• China, Korea, USA, Italy

Future science aligned with national and international priorities and directions

RCP 8.5 business as usual

RCP 2.6 Paris target

• RCP 2.6 saves the Antarctic ice shelves

• More than 2°C above pre-industrial commits Antarctica to ongoing melt and sea-levels up to 10m above present.

• A critical issue for future ACTS is mitigation strategy to achieve Paris target
