Ralph Regenvanu, Vanuatu’s Minister for Climate Change speaks to Christiane Amanpour about the landmark climate ruling by the International Court of Justice.

The paramount chief of a volcanic island in Vanuatu said Thursday he was "very impressed" by the ICJ's declaration that countries must tackle climate change.

Student Vepaiamele says the international court's advisory opinion also affirms countries' legal obligations to combat climate change and protect human rights.

The United Nations’ top court in a landmark advisory opinion says countries could be in violation of international law if they fail to take measures to protect the planet from climate change, and nations harmed by its effects could be entitled to reparations.

Britain can dodge climate lawsuits from other countries if it makes “significant and meaningful” contributions reflecting its historical responsibility for global warming to a UN fund, Vanuatu’s lawyer has said.
