The European 'Beyond EPICA - Oldest Ice' project reached bedrock at Little Dome C, East Antarctica, in January 2025, at a depth of roughly 2,800 m — recovering a continuous ice-core climate record estimated to extend back about 1.2 million years, more than 400,000 years further back than the previous record held by the original EPICA Dome C core (about 800,000 years). The extended record is expected to help explain why the pace of Earth's ice ages shifted roughly 900,000-1,200,000 years ago.

The greatest age of any continuous, dated climate record recovered from a single ice core.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
