-
A.
Younger Dryas cold event
chosen
The Younger Dryas cold event was a brief, abrupt return to near-glacial conditions about 12,900–11,700 years ago that interrupted the general warming trend at the end of the last Ice Age.
-
B.
Last Glacial Maximum
The Last Glacial Maximum was the most recent period in Earth’s history when ice sheets reached their greatest extent, dramatically lowering sea levels and reshaping global climates and ecosystems.
-
C.
Huronian glaciation
The Huronian glaciation was one of Earth's earliest and longest ice ages, occurring over 2.4 billion years ago and likely linked to the Great Oxidation Event and major climatic shifts.
-
D.
8.2 kiloyear event
The 8.2 kiloyear event was a sudden, short-lived global cooling episode during the early Holocene, likely triggered by massive meltwater outbursts disrupting North Atlantic ocean circulation.
-
E.
Würm glaciation
The Würm glaciation was the last major glacial period of the Pleistocene in the Alps, marked by extensive ice coverage and shaping much of the region’s modern landscape.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
