![]() ![]() Because of its significant depth - 24 metres - and narrow surface of a few hectares, Crawford’s deeps never mix and are essentially cut off from the world. The scientists chose Crawford Lake because of the remarkable clarity and depth of its sedimentary record. “Anything that came out of smokestacks or tailpipes, that’s what we see,” McCarthy said.Īll of the 12 candidates considered for the Golden Spike showed the same signals, said McCarthy. Atmospheric changes alter what filters down from the sky. Many of these accelerations show up in the geological record.įertilizer use changes which nitrogen compounds are deposited. They all spike dramatically right around 1950. The year also coincides with the beginning of the so-called “Great Acceleration,” a time when everything seemed to suddenly take off.Ī 2015 paper in the journal Anthropocene Review produced 12 graphs on everything from population to GDP to fertilizer use to dam construction to energy consumption to international travel. The element does not occur in nature and is the result of widespread nuclear weapons testing. That’s when plutonium-239 begins to show up in geological strata. Some geologists initially suggested a new epoch should begin with the Industrial Revolution, when fossil-fuel combustion began in earnest. That will bring to a close a debate geologists have been having since 2009: have humans altered the planet’s functioning profoundly enough to change its geology, and if so, should a new geological epoch be declared? The matter is to come to a final vote at the International Union of Geological Sciences in August 2024. ![]() Geologists are to debate the issue, including whether the Anthropocene should be declared at all, in the fall. The recommendation was announced Tuesday at the International Congress on Stratigraphy in Lille, France. Her group says the lake along the Niagara Escarpment should be considered the location for the so-called “Golden Spike” marking the start of the Anthropocene. “Within that short span of time, the system flipped and can’t go back to the way it used to be.” “It’s a bit sobering,” said Francine McCarthy, a Brock University geologist who was on the research team for the Anthropocene Working Group of the International Union of Geological Sciences. Previous ambassadors include Pierce Brosnan’s sons Dylan and Paris Brosnan, Idris Elba’s daughter Isan Elba, and Dwayne “The Rock” Johnson’s daughter Simone Garcia.Īwards season kicked off Monday with the Gotham Awards, where "Nomadland" took home best feature in a hybrid virtual ceremony with no audience but live presenters at New York's Cipriani Wall Street.A team of geologists has concluded, after studying sites around the globe, that a tiny, deep lake in southern Ontario should mark the birth of the modern world.Ī few layers of sediment from around 1950 at the bottom of Crawford Lake, they say, show more clearly than anywhere else how human activities have changed the planet’s functioning to the extent that a new geological epoch should be declared: the Anthropocene, or the age of people. “We’re proud to carry our father’s legacy of storytelling to bring attention to communities close to our hearts,” Satchel said in a statement.Īdded Jackson: “As a visionary creative, my dad taught Satchel and me the importance of entertainment as a cultural catalyst of change." ![]() ![]() Satchel is partnering with Callen-Lorde, an organization that helps with LGBTQIA+ communities in New York City, while Jackson is partnering with Big Brothers Big Sisters, the volunteer-supported mentoring network.
