Record-Breaking Climate Data

A Europe-wide collaboration has unveiled the longest continuous record of Earth's climate and atmospheric conditions to date. The data were extracted from an ice core drilled to a depth of 2.8 kilometres in Antarctica.

This ice core provides a continuous record stretching back 1.2 million years. According to reports, this represents the longest continuous record of the Earth's climate ever obtained.

Scientific Significance

The extraction of the core allows researchers to access data regarding the planet's climate history that was previously unavailable. By analyzing the layers of ice, scientists can reconstruct atmospheric conditions and temperature fluctuations over a period exceeding one million years.

From the editor

Verified the previous fix landed correctly — the unsupported paleoclimatology sentence citing source [^6] (empty snippet) has been removed. All remaining body claims and key facts trace to sources [^2] and [^3], whose snippets directly support the 1.2-million-year record, 2.8-kilometre depth, Antarctic location, and Europe-wide collaboration. Sources [^4], [^5], and [^7] are unused and harmless. No fabricated quotes, no overreach, no single-sourcing issues in the current draft.
