titled "Involve social scientists in defining the Anthropocene." In it, they argue that a rush to confirm the 1950s as the beginning of a new geologic epoch in the history of the planet is a mistake.Instead, the researchers call for deeper deliberation with a broader range of academic expertise, greater transparency and a new international institution to oversee all of this.To help you learn and understand key social sciences terms and concepts, we’ve identified some of the most important ones and provided detailed definitions for them, written and compiled by Chegg experts.Due to their outstanding resolution and well-constrained chronologies, Greenland ice-core records provide a master record of past climatic changes throughout the Last Interglacial–Glacial cycle in the North Atlantic region.

Ask yourself how the things that are happening in the world today might end up being recorded in the sediments that are now or soon will be deposited.The data not only resolve the well-known sequence of Dansgaard–Oeschger events that were first defined and numbered in the ice-core records more than two decades ago, but also better resolve a number of short-lived climatic oscillations, some defined here for the first time.Using this revised scheme, we propose a consistent approach for discriminating and naming all the significant abrupt climatic events of the Last Glacial period that are represented in the Greenland ice records.How would today's sediments appear to a geologist millions of years in the future examining outcrops of sedimentary rock that originated in our time?What would the geologist be able to deduce about the world we live in, based on what was left in the strata?

The GS and GI periods are the Greenland expressions of the characteristic Dansgaard–Oeschger events that represent cold and warm phases of the North Atlantic region, respectively.
