The Cataclysmic Break That (Maybe) Occurred in 1950
Sixty-nine years ago, a new geological era may have begun on Earth.
Robinson Meyer Apr 16, 2019
"Here is the hypothesis: Not so long ago, the very nature of planet Earth suffered a devastating rupture. The break was sudden, global, and irreversible. It happened on a Sunday within living memory. Mick Jagger, Meryl Streep, and Caitlyn Jenner were all born before this crack in time. Vladimir Putin, Liam Neeson, and Mr. T were all born after it." ...
"Starting next week, the committee’s 37 members will vote on two questions. First, should the Anthropocene be added as a new epoch to the Geological Time Scale, the standard scientific timeline of Earth’s 4.5-billion-year history? Second, should the Anthropocene, if it does exist, commence in the middle of the 20th century?" ...
"It was “the Big Zoom,” he said, borrowing a phrase from the journalist Andrew Revkin. There is “nothing really comparable” to that shift in any other period of Earth history. Even setting carbon pollution aside, he said, the spike in fertilizer use led to the largest jump in surface nitrogen levels in 2.5 billion years. Zalasiewicz hopes the committee will start the Anthropocene in the middle of the 20th century."...
"The idea of the Anthropocene was first proposed by the Nobel-winning chemist Paul Crutzen in 2000. Since then, it has caught on more broadly in culture, even though it is not a formal term in geology. (The musician Grimes is releasing an Anthropocene-themed album later this year.) But it could soon have its day: If the working group accepts its existence, that will clear the way for the International Commission on Stratigraphy and the International Union of Geological Sciences to accept it in full."...!
