Organic carbon sampled in the lake contained radiocarbon, indicating connection to the ocean in the mid-Holocene, when the grounding line was up to 260 kilometers inland of its current position.
Through a local fixed time-step filter, global Holocene magnetic field models remain mathematically tractable refining our insight into field variability and improving archeological dating.
Ancient plant and animal DNA buried in Arctic sediments preserve a 50,000-year history of Arctic ecosystems, suggesting that climate change contributed to mammoth extinction.
Humans may be in a new geologic epoch—the Anthropocene—but different groups define its start at varied times. When should the Anthropocene have begun?
Roughly 1,500 years ago, the Tierra Blanca Joven eruption blanketed Central America in ash and likely displaced Maya settlements, new research shows.
East Asia’s Black Current may have rerouted in the past 10,000 years or so.
Old coral colonies suggest that a prehistoric warming event called the mid-Holocene Thermal Maximum may have occurred earlier than previously thought.
Two recent papers in Earth's Future discuss the addition of a new epoch to the geological timescale.
Ice core data, archeological evidence, and other studies suggest humans had a significant influence on Earth's preindustrial climate.
Geologists must consider whether the Anthropocene is a specific segment in the continuum of time or a holistic concept.
