Measured timeline

📍 The outcome

Scientists proposed a new theory explaining why Antarctica froze millions of years before the Arctic. The research suggested that ancient mantle waves may have lifted Antarctica's mountains and that the breakup of Gondwana contributed to the ice growth.

The obvious questions

When did Antarctica freeze according to the new theory?

According to IFLScience, Antarctica froze 34 million years ago.

What geological event contributed to the freezing?

Coverage mentions the breakup of Gondwana over 100 million years ago and the influence of ancient mantle waves that may have lifted mountains.

How does this compare to the Arctic?

The reports state that Antarctica became engulfed by ice many millions of years before the Arctic.

  • Source Integrity: Verified strictly against primary headline reporting under zero-hallucination protocols.

Scientists have developed a new theory regarding the timing of Antarctic glaciation. Research suggests that Antarctica, once part of the supercontinent Gondwana, became engulfed by ice millions of years before the Arctic experienced similar conditions.

Coverage from Phys.org, Reuters, and Discover Magazine emphasizes the role of ancient mantle waves inside the Earth, which may have lifted Antarctica's mountains prior to the freeze. Other reports from GFZ and eos.org link the process to the breakup of Gondwana over 100 million years ago.

Further analysis will likely focus on the specific mechanisms of the 34-million-year-old freezing event and the impact of the continent's geological history on current ice presence.
