Each one of those bars aggregates 10 years of data. And the trend, particularly in recent years, is clear: The world is getting warmer. “The period 2000-2010 was the warmest decade on record since modern meteorological records began around 1850,” the authors write.
The slowdown in rising temperatures over the past 15 years goes from being unexplained to overexplained
Alexander Johannison, a nuclear physicist working at the United States Atomic Energy Commission, is mystified when his Geiger Counter starts failing to detect radioactivity. Over a period of time, his colleagues also notice the same strange events, but when he finally reports to his boss, no-one will take him seriously and he realises that he is the only one who is still aware of the existence of radioactivity.
Thinking that maybe an enemy has removed all knowledge of nuclear energy and nuclear weapons and is about to invade the United States, he goes home and finds a stranger there talking to his wife. The stranger, who looks like an impossibly perfect human, explains that he is an entity from ‘outside the Universe’. He has been assigned to perform an ‘operation’ on humanity to save them from a potential nuclear holocaust. As part of the operation, all knowledge of radioactivity has been removed from humanity for five years. Also, all radioactive elements no longer exist. After the Pause, about one hundred people, including Johannison, will have the task of re-educating humanity in the peaceful use of nuclear power.
The story ends on a sinister note, as, in discussing the visit with his wife, Johannison points out that the visitor at one point referred to the Earth as “the yard”, mistakenly using its own context in the reference rather than ours. Johannison concludes that it regards the Earth as a “barnyard” and humans as mere cattle who have to be controlled.
