Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'ледяной век' for figurative use; it may sound unnatural. Use 'период застоя', 'холодный период' instead.
- The term 'ледниковый период' is the correct scientific equivalent, not 'ледяной век'.
Common Mistakes
- Using 'ice age' uncapitalized when referring to the specific Pleistocene Ice Age (formal geology capitalizes it: 'the Ice Age').
- Confusing 'ice age' (long epoch) with 'glaciation' (a shorter cold phase within an ice age).

Frequently Asked Questions
In general writing, it is often lowercase ('ice age'). In formal geological contexts referring to the specific Pleistocene epoch, it is usually capitalized ('the Ice Age').
Yes, technically. We are in the Quaternary ice age, but currently in an interglacial warm period (the Holocene) within it.
An 'ice age' is a long period (millions of years) with persistent ice sheets. A 'glaciation' is a shorter cold phase within an ice age when ice sheets advance. We are in an ice age but not in a glaciation.
Yes, it is commonly used to describe any prolonged period of stagnation, cold relations, or lack of progress (e.g., 'an ice age in negotiations').
