"It could be that the 2016 Games are the last Olympics in the history of mankind," Ishihara told reporters at a Tokyo 2016 press event ahead of the vote.
"Global warming is getting worse. We have to come up with measures without which Olympic Games could not last long.
"Scientists have said we have passed the point of no return," said Ishihara.
WASHINGTON — The FBI is investigating the hanging death of a U.S. Census worker near a Kentucky cemetery, and a law enforcement official told The Associated Press the word 'fed" was scrawled on the dead man's chest.
The body of Bill Sparkman, a 51-year-old part-time Census field worker and occasional teacher, was found Sept. 12 in a remote patch of the Daniel Boone National Forest in rural southeast Kentucky. The Census has suspended door-to-door interviews in rural Clay County, where the body was found, pending the outcome of the investigation.
Investigators are still trying to determine whether the death was a killing or a suicide, and if a killing, whether the motive was related to his government job or to anti-government sentiment.
Investigators have said little about the case. The law enforcement official, who was not authorized to discuss the case and requested anonymity, said Wednesday the man was found hanging from a tree and the word "fed" was written on the dead man's chest. The official did not say what type of instrument was used to write the word.
The U.S. Census Bureau is overseen by the Commerce Department.
