2080

2080 was a year.
By this year, the Amazon Rainforest on Earth had become the Amazon Desert after the eco-system collapsed. When the Fifth Doctor and Turlough arrived in Brazil for the Rio de Janeiro carnival, they found shanty towns instead. (AUDIO: Loups-Garoux)
Whilst in space, the Cybermen took control of the Silver Carrier. Eight weeks later, they caused an explosion in the Perseus Cluster. (TV: The Wheel in Space)
