In May 2014, the New Zealand Court of Appeal dismissed a claim by Kiribati citizen that sea level rise due to climate change was making his country uninhabitable and that he and his family should be allowed to stay in New Zealand as refugees.
While the court didn't agree with the claim, stating there is no provision under the international refugee convention covering environmental displacement, it agreed climate induced sea level rise and other effects posed a real problem in the Pacific. The prospect of possible relocation is faced by people in Small Island Developing States like Kiribati, and in Arctic coastal communities like Shishmaref and Newtok, Alaska. MSV held a workshop to address this issue during COP 19 Warsaw, Poland, as part of a larger initiative on climate change and community-based relocation.
