The [Uncertain] Four Seasons is an algorithmic re-composition of Vivaldi’s ‘The Four Seasons’. Developed by composers, musicians, climate and computer scientists using geospatial climate predictions for 2050.

On November 1, 2021, in the hours leading up to COP26 in Glasgow, orchestras from around the world will perform their variation of The [Uncertain] Four Seasons in a global, 24-hour streaming event that aims to place further pressure on leaders to sign the Leaders Pledge for Nature, and commit to reversing biodiversity loss by 2030.
