What is The Grantham Climate Art Prize?


The Grantham Climate Art Prize is an award for young artists to communicate messages about climate change.

Art has the potential to inspire minds and touch emotions in a way that science alone often finds challenging. We felt an exchange between artists and scientists would be a worthy endeavour, and might lead to a fuller, wider appreciation of climate issues and how they can effectively be explained. We hope this prize will draw local communities together behind positive action.
