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.

At the start of Youth and Public Empowerment Day at COP26 on November 5th 2021, The [uncertain] Four Seasons will release the performances of 14 orchestras from across 6 continents – half of which are youth orchestras. The performances elevate the voices of young people in the ongoing movement for climate action, and place further pressure on world leaders to sign the Leaders Pledge for Nature, and thereby commit to reversing biodiversity loss by 2030.

The following variations and orchestras are confirmed to perform:
