Today is the anniversary of a doomsday prediction made by Swedish climate campaigner Greta Thunberg when she was just 15 years old June 21st 2018, stating the human race had five years to end fossil fuels or face certain death. She wrote then:

A top climate scientist is warning that climate change will wipe out all of humanity unless we stop using fossil fuels over the next five years.

While these alarming, but later forgotten warnings with very definite and certain sounding timescales are a major part of green propaganda, this particular instance has taken on a life of its own due to the Streisand Effect, given as the deadline date approached Thunberg was caught having deleted the claim.
