Predicted/scheduled events[edit]


  • Global sea levels could rise by 6.8 metres (22 ft) by the 31st century under a high emissions scenario.[1]
  • 3015: A camera placed by Jonathon Keats will finish its exposure time after its placement at the ASU Art Museum in Tempe, Arizona, in 2015.[2]
  • 3016: According to Stephen Hawking, humanity may be doomed by this time due to climate change, nuclear war, and/or artificial intelligence unless space colonization is achieved.[3]
  • 3117: Minimum time by which, according to physicist Andrew Kennedy, humanity can expect to have reached Barnard's Star, assuming an annual economic growth rate (and corresponding increase in power output) of 1.4% from 2007.[4]
  • 3183: The time pyramid, a public art work at Wemding, Germany, is scheduled for completion.[5]
  • 3500: Re-inception of a period of cyclical polar glaciation if atmospheric CO2 concentrations did not exceed a low 240 parts per million by volume (ppmv), however currently exceeding 390. This date would be greatly prolonged even if restored to a pre-industrial 280.[6]
