The Nakheel Tower is a 4000-foot tall super skyscraper located in Dubai Waterfront. If people disappeared from the tower, how long can it last in high humidity?
1 day after people: Power plants shut down everywhere in Dubai. At night, the Nakheel is completely dark. Mold growth and other nasties build up due to extremely high humidity.
250 years after people: Corossion and humidity have destroyed the pretty exterior of the Nakheel. A sandstorm larger than the July 2011 Arizona storm hits Dubai. The 1 kilometer high Nakheel tower leans over into the sea creating an enormous collapse.
