Turned 60, is the Antarctic treaty system in good health?

Signed in 1959, the Antarctic Treaty is usually hailed as an example of what
states can achieve when they leave aside their interests and truly collaborate. It
was over 30 years ago, however, that the last significant legal instrument of the
Antarctic Treaty System (namely, the Protocol on Environmental Protection)
was signed. Since then, no new legal instruments have been drafted, despite
a number of growing internal and external challenges. In this special issue,
an interdisciplinary group of scholars examine some of these challenges and
evaluate whether the system is well prepared to tackle them. Their point of
agreement is that, if not severely ill, the system's chronic ailments—particularly
laggardness—must be addressed if it is to respond satisfactorily to rapid social,
political, environmental and economic changes on a global scale.
