Much ink has been spilt on the study of climate change fiction (cli-fi), whereas relatively less attention has been devoted to the burgeoning growth of climate change poetry. As a sub-genre of ecopoetry which aims at dealing with realistic environmental issues and raising readers' awareness to protect the earth, climate change poetry not only represents the ongoing climatic crises in varied ways, be they realistic or imaginative, but also actively engages in provoking ecological responsibilities and environmental activism.
