Paleogene climatic optimums

Target entity: Paleogene climatic optimums
Context triple: [Neogene, precededBy, Paleogene climatic optimums]

• A. Eocene–Oligocene climate transition
  The Eocene–Oligocene climate transition was a major global cooling event around 34 million years ago that marked the shift from a greenhouse to an icehouse Earth, including the formation of large Antarctic ice sheets.
• B. Holocene climatic optimum
  The Holocene climatic optimum was a warm period roughly 9,000–5,000 years ago when global temperatures, especially in the Northern Hemisphere, were higher than today, influencing the spread of forests and early human civilizations.
• C. Cenozoic glaciations
  Cenozoic glaciations are a series of major ice age cycles during the Cenozoic Era that saw extensive growth and retreat of continental ice sheets, profoundly shaping Earth’s climate and landscapes.
• D. Snowball Earth glaciations
  Snowball Earth glaciations were extreme global-scale ice ages in the Precambrian when ice sheets may have covered most or all of Earth’s surface for millions of years.
• E. Milankovitch cycles
  Milankovitch cycles are long-term variations in Earth’s orbit and axial tilt that drive natural climate fluctuations, including the timing of ice ages.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Paleogene climatic optimums
Target entity description: Paleogene climatic optimums were intervals of exceptionally warm global climate during the Paleogene Period that set the stage for the cooler conditions of the subsequent Neogene.
