Doggerland and Sundaland represent two of the most significant landmasses lost to post-glacial sea level rise, together encompassing hundreds of thousands of square kilometers of habitable terrain that was progressively
E_2_17 — Campanian Ignimbrite: 40,000 BP European Super-Eruption
The Campanian Ignimbrite (CI) eruption — also known as the CI super-eruption — was the largest volcanic event in the Mediterranean region during the past 200,000 years and one of the largest explosive eruptions in the La
E_2_07 — The 4.2 Kiloyear Event — Bronze Age Climate Catastrophe
The 4.2 kiloyear event (~2200 BCE) was a severe, century-scale aridification episode that constitutes one of the most significant abrupt climate changes of the Holocene. Identified through speleothem, marine sediment, an
E_2_02 — Toba Supervolcano and the 74,000 BP Genetic Bottleneck
Approximately 74,000 years ago, the Toba supervolcano on the island of Sumatra (modern Indonesia) produced the largest volcanic eruption in the last 2 million years: a VEI-8 (Volcanic Explosivity Index maximum) event tha

E_4_13 — Milankovitch Cycles and Orbital Forcing
Milankovitch cycles are periodic variations in Earth's orbital geometry that modulate the distribution and intensity of solar radiation reaching Earth's surface, driving the glacial-interglacial cycles that have dominate

E_4_11 — The Holocene Climate Optimum and Mid-Holocene Transition
The Holocene Climate Optimum (also called the Holocene Thermal Maximum or Hypsithermal) designates a prolonged warm interval roughly spanning 9,000–5,000 years before present, during which Northern Hemisphere summer temp
E_4_09 — Magnetic Pole Reversals and the Laschamp Event
Earth's magnetic field periodically undergoes geomagnetic reversals — events in which the north and south magnetic poles swap polarity. This has occurred at least 183 times in the last 83 million years, with the last ful
