A small lake in Canada is key to understanding the dawn of the Anthropocene epoch. Crawford Lake, located near Toronto, has preserved layers of sediment that record the history of human activity on Earth. By analyzing these layers, researchers had confirmed that the Anthropocene began in 1950s, when hydrogen bomb tests left a global trace of radioactive fallout. #Anthropocene #CrawfordLake #History https://www.sciencealert.com/a-lake-in-canada-defines-the-moment-we-changed-earth-forever?utm_source=flipboard&utm_content=HariTulsidas%2Fmagazine%2FArchetypes

The thot plickens.. “Meanwhile, the proposal that #Anthropocene is a geologic epoch, with #CrawfordLake as its representative, now advances to the next level and, if it succeeds, to a vote by the International Commission on Stratigraphy. The whole idea can still be vetoed by the International Union of Geological Sciences, which holds a congress once every four years and is next set to meet in Korea in the summer of 2024.”

Digging deep into a humble lake in Canada, scientists found a spot on Earth like no other — and a record that could redefine our history of the planet

The tipping point in #ClimateChange is now being traced to the 1950s. More importantly, even though some of these changes are irreversible, we can drastically improve our planet survival if we curb #GlobalWarming, pollution and declines in #biodiversity

"In just seven decades, the scientists say, humans have brought about greater changes than they did in more than seven millennia. Never in Earth’s history has the world changed this much, this fast. Never has a single species had the capacity to wreak so much damage — or the chance to prevent so much harm."

"No other water body is known to possess this particular combination of attributes, making #CrawfordLake a unique bellwether of global change"
