As the prospects of significantly mitigating climate change through emissions reductions become dimmer, the critical necessity of adaptation has become clearer, with failure-to-adapt litigation possibly playing an important role in bringing adaptation measures to pass.

It unanimously determined that State Parties to the United Nations Convention on the Law of the Sea have specific obligations to take all necessary measures to prevent, reduce, and control marine pollution from anthropogenic greenhouse gas emissions.
