Does the science criterion rest on thin ice?

This paper explores whether a central plank of the Antarctic Treaty System (ATS) - the science criterion - is threatened by anthropogenic climate change. It begins by situating the origins of the ATS within the context of the International Geophysical Year (IGY), and the privileged position that science obtained within first the IGY and later the ATS. This extends to science functioning as the dominant currency through which states may ascend to the level of consultative parties (CPs), the highest level of authority within the ATS.
