they hold the fingerprints of human activity from the byproducts of fossilfuels, microplastics, and the fallout from nuclear weapons testing. and it s the plutonium from these nuclear tests that s being isolated here to determine which year the anthropocene started. we re looking at the plutonium radioactivity in the early 1950s. that was the point when this almost entirely artificial product was globally dispersed. and we pick it up from the early 1950s in sediments all over the globe. the last epoch change happened more than 11,000 years ago. a record is buried in a bog on the isle of wight. this is a really beautiful transition. you see the difference in the colour of sediments. the darker mud belongs to the ice age. the lighter mud is where the warmer holocene epoch began. but there s a major difference compared with what s happening now. these are natural changes here. this is a natural system that drives these changes. what we are doing right
i am quite sure 1950 is right around here. that would be the base of the proposed anthropocene epoch. this new epoch defines the moment humans started having a bigger impact on our planet than anything else. so we refer to the anthropocene as the interval of time since the mid 20th century when the great acceleration of human industry, it changed the way the earth behaves. it basically is a tipping point that was reached that altered earth s history forever. some of that core has been sent to southampton university. what s inside these little files doesn t look like much, just a scrape of canadian mud. but each one of these contains material from a particular year. and crucially, one will help to pinpoint the exact moment when the anthropocene began. these sediments can be analyzed.

cal tentacles, it could play out in a number of ways. if special counsel jack smith does indict donald trump on this, how earth do courts manage three different diments you have in the hushmon classified documents case, you also have january 6th and potentially the georgia election meddling. how does a court maneuver this if. i ve never heard or seen anybody who has been under three different indictments, if we get one more, never mind four, from four different jurisdictions at the same time. this will be a mess. because classified documents is in florida and january 6th would theoretically be in d.c. we have the state charge here in manhattan. some of this could play to donald trump s advantage because his best defense here, his best strategy is delay. we will not try three or four
