With its track record of climate disruption and unabated emissions growth, 2018 might sow doubt about the viability of meaningful climate action. And yet, by following a trajectory from international cooperation to efforts at the national and subnational level, and even to the role of traditional indigenous practices, the articles in this issue collectively affirm both the importance and availability of climate solutions that transcend all geographic, political and cultural boundaries.

In addition to articles on COP 24, indigenous knowledge in climate solutions, liability and responsibility, climate change and the Security Council and discontinuity and conflict in U.S. climate policy, this issue includes reports on legal developments in Europe and internationally.
