If you watch, read, or listen, to Terry Nation’s “Survivors” (1975) – you will see civilisation suddenly collapse due to a type of flu that is spread around the world via jet-liners (international travelling being a relatively new phenomena for the masses at the time). The USSR existed then and the US was engaged in a “Cold War” with it at the time (it turns out that illnesses are no respecter of political ideology). The US laughably believed that the Soviets possessed a “weather-altering machine” and would use it to usher-in a new ice-age. To this end, the US government ordered the British government (something of a US lap-dog at the time) to put-out the false propaganda that an “ice-age” was coming! The BBC made disinforming series about this whilst academics happily conformed despite all the data denying this assertion. This was the fake climate change argument of the day – and individuals lost their career when denying it.
